.rain will overspread the area today as a warm front lifts north
of lake erie. a secondary round of rain will accompany a cold front
sweeping east across the region overnight. most areas will receive
between a half inch and an inch of rain...with locally higher
amounts possible where thunderstorms occur. additional run off
will be released from the melting snow pack as temperatures
approach 50 degrees by this evening. with the ground frozen...run
off from melting snow and rainfall will lead to rises on area
rivers. most rivers contain a considerable amount of ice which
could break up and jam as rivers rise and temperatures warm.
ponding of water and flooding of some roads and basements will
also be possible as snow continues to block drainage systems.

from 3 pm est this afternoon through friday morning

a combination of melting snow and rain will produce a threat
of flooding from thursday afternoon into friday. ice jams on
area rivers may also produce flooding.

new rainfall of a half to one inch is expected. localized
amounts up to two inches are possible from thunderstorms.

a significant amount of water will be released by the melting
snow as warmer temperatures move in on thursday. rain will
enhance the flood threat and any heavy rain could produce
significant flooding. some river flooding is likely. ice jam
flooding can develop quickly and make for a more dangerous flood
risk. in addition to flooding on streams and rivers... flooding
of basements and poor drainage areas is also possible.

precautionary/preparedness actions...

a flood watch means there is a potential for flooding based on
current forecasts. you should monitor later forecasts and be
alert for possible flood warnings. those living in areas prone to
flooding should be prepared to take action should flooding
develop. stay tuned to weather radio for further details or
updates

synopsis...
low pressure over the southern plains will undergo rapid deepening
as it tracks northeast across the upper midwest today. this system
will lift a warm front north across the area towards midday...followed
by a strong cold front sweeping east tonight. the low will move
north across lake superior on friday...with a ridge building over
the southern great lakes on sunday.
&&

near term /until 6 pm this evening/...
active forecast as a developing area of low pressure over the
southern plains tracks northeast and undergoes rapid
intensification. an area of showers and thunderstorms can be seen
over illinois moving northeast along the elevated front aloft and
this area of precipitation will make rapid progress towards nw ohio
this morning as a 50-60 knot low level jet approaches. the dry
resident airmass in place will quickly be overcome with moisture as
pw values increase from 0.25 to 1.00 by 18z. concerns early this
morning include patchy freezing fog in ne ohio/nw pa where skies
have been clear most of the night. also some concern that easterly
flow off lake erie in nw ohio will slow warming this morning with a
brief window of freezing rain possible before temperatures warm.
upstream observations show temperatures warming into the mid 30s
immediately ahead of the rain...and given that it won't arrive
until around 10 am think rain is the most likely scenario.
however...warm fronts tend to slow as they approach the frozen
lake erie so did include a brief mention of freezing rain. this
will not occur until after the morning commute is over.
thunderstorm activity continues to expand to the west and did
include a chance of thunderstorms all areas today as elevated
instability increases. a flood watch remains in effect as we
continue to melt the snowpack compounded by multiple rounds of rain
expected today. the heaviest rain during the daytime hours will be
focused across nw ohio where 0.50 to 1.00 of rain is likely. the
ground remains frozen so this water and water being released from
the snowpack will channel into area waterways. ponding of water may
be aggravated by drainage systems that are clogged by lingering
snow. thunderstorms during the daytime hours are not expected to
pose a threat of severe weather due to the very stable layer near
the surface. there will be a very strong wind field aloft with winds
near 850mb of 50 knots but these are not expected to mix to the
surface. the exception to this will be erie county pa where
southeasterly downsloping winds will gust to 45 mph by late
afternoon.
temperatures will be a little deceiving for today as forecast highs
in the mid 40s to low 50s will not occur until this evening. the
warming will be slowed by clouds and rain through mid day with
southerly winds ramping up into tonight. areas of fog are expected
mainly across nw ohio as dewpoints increase with additional
moisture from the melting snowpack and cool flow off lake erie.
&&

short term /6 pm this evening through saturday night/...
by 00z...a 982 surface low will be located west of
chicago...continuing to move north with a cold front pushing east out
ahead of it. convection is expected to develop along the cold
front moving eastward with some uncertainty in how far north the
surface based convection will extend. for now the storm prediction
center has kept the slight risk for severe thunderstorms just
south of the forecast area. it is possible that these
thunderstorms could only reach as far north as central ohio...but
think there is a decent chance of them extending into north
central and north east ohio. have issued a wind advisory for the
entire forecast area for tonight as the strong cold front moves
through the area. if convection does reach nrn ohio then severe
thunderstorm watches/warnings may also be needed. thunderstorms
will mostly likely occur between 9 pm and 2 am.
there is some concern that models may be struggling with
temperatures this evening because of the snow pack and that we may
actually make a run at the mid 50s...increasing the severe weather
threat. whether it is from the convection or just strong downward
momentum along the front...think wind gusts to 50 mph are likely and
could exceed 60 mph with convection. winds may also be a little
stronger in nw ohio where the strongest winds and downward momentum
will occur behind the front. qpf will range from 0.50 to 1.00 inch
again but the heaviest rain will likely extend from central ohio to
nw pa which may not receive as much during the first round thursday
afternoon.
winds will remain strong through the day on friday as the low
departs to the north. the atmosphere will be well mixed through
nearly 800mb and a 45-50 knot wind field remains in place at 850mb.
wind gusts to 50 mph will be possible again...likely strongest in
the north.
there will be some warm advection on saturday ahead of the next weak
frontal push. highs will reach the 40s most areas and include a
chance of showers most areas...possibly mixing with snow in nw
ohio.
&&

long term /sunday through wednesday/...
the flow aloft will be fast and zonal at the start of the period.
the models continue to have differing solutions as far as the timing
and movement of the individual impulses is concerned. sunday should
be dry but some lake enhanced snow showers could occur sunday night
into monday. it appears the best chances for precip during the
period will come monday night into tuesday. the ecmwf continues to
show a wave moving across the region at that time. a period of
light snow is probable. this solution is similar to the models
previous couple of runs. the gfs continues to vary a lot from run
to run so will follow the more consistent ecmwf. will need to
continue with a mention of lake effect into wednesday. for those
wanting spring...you will have to wait a while longer. high temps
the entire period will be well below normal and at least 15 degrees
below normal from monday on.
&&

aviation /06z thursday through monday/...
rain shield now into western illinois should reach nw oh toward
daybreak and spread across the entire area by early afternoon.
still possible to see some freezing rain nw oh...roughly in the
13 to 15z time frame...but did not put into taf as still doubts in
my mind. think temps will rise above freezing point at other taf
sites by the time precip arrives.
warm front now across tennessee will lift across the area
tomorrow afternoon. as it does expect to see at least areas of
ifr cig/br until front lifts north.
by 18z the 925mb winds increase to 40-50 knots...may see a little
llws with the warm front itself.
strong cold front will move across the area thursday night. expect
tsra to develop ahead of the front and move across the area thursday
evening. doubts in my mind as to how widespread it will be in our
forecast area. spc keeps slt risk area to our south.
outlook...non-vfr ne oh/nw pa friday and maybe sat in -shsn. some
non-vfr possible again sunday and maybe snowbelt on mon.
&&

marine...
a strong cold front is still on track to cross the lake later
tonight. will see increasing se flow today and s flow tonight ahead
of the front. sw flow behind the front will increase to gale force
on friday. have trimmed the watch start time back several hours.
it still a little far out to hoist the gale. have coordinated with
buffalo and expect the day crew to go with a warning. speeds will
gradually diminish friday night. west to southwest flow will then
continue through the end of the period. a line of convective
showers will likely cross the lake tonight. expect gusts with the
line to be close to gale force.

area of rain already into nw ohio with temperatures slowly
creeping up. lima was up to 36 degrees and defiance was up to 33
degrees ahead of the rain although temperatures at tol/fdy remain
at or below freezing. some evaporational cooling may occur as
rain begins with dewpoints still in the upper 20s. left a brief
chance of freezing rain in the forecast for nw ohio this morning

aviation /12z thursday through monday/...
a warm front over southern ohio will lift north across the area by
18z. precip associated with this front will move into nw oh by mid
morning. temps at ktol and kfdy remain below freezing. think kfdy
may climb above freezing before the rain starts but ktol may see a
brief period of fzra. will try to time the precip east across the
remainder of the area. expect keri to remain dry till late
afternoon. warmer and more humid air will arrive behind the front
and expect widespread ifr cigs and vsbys to develop as the snow
continues to melt. little improvement is expected till a cold
front arrives later tonight. it appears that a line of convection
will develop ahead of the front and move across the local area
beginning later this evening. will not include any thunder in the
tafs for now...but thunder is certainly a possibility...especially
in the south.
the other big concern today is the winds. se flow will gradually
increase today and then become s toward evening. the flow will
become sw behind the cold front. gusts to 30 knots are likely by
late afternoon most areas with gusts to 40 knots or greater with
any convection that forms and also right behind the cold front.
keri will see a good set up for downsloping winds and gusts to 40
knots are possible there by late afternoon.

likely occur between 9 pm and 2 am.
there is some concern that models may be struggling with
temperatures this evening because of the snow pack and that we may
actually make a run at the mid 50s...increasing the severe weather
threat. whether it is from the convection or just strong downward
momentum along the front...think wind gusts to 50 mph are likely and
could exceed 60 mph with convection. winds may also be a little
stronger in nw ohio where the strongest winds and pressure falls will
occur behind the front. qpf will range from 0.50 to 1.00 inch
again but the heaviest rain will likely extend from central ohio
to nw pa which may not receive as much during the first round
thursday afternoon.
winds will remain strong through the day on friday as the low
departs to the north. the atmosphere will be well mixed through
nearly 800mb and a 45-50 knot wind field remains in place at 850mb.
wind gusts to 50 mph will be possible...likely strongest in the
north.
there will be some warm advection on saturday ahead of the next weak
frontal push. highs will reach the 40s most areas and include a
chance of showers most areas...possibly mixing with snow in nw
ohio.
&&

aviation /12z thursday through monday/...
a warm front over southern ohio will lift north across the area by
18z. precip associated with this front will move into nw oh by mid
morning. temps at ktol and kfdy remain below freezing. think kfdy
may climb above freezing before the rain starts but ktol may see a
brief period of fzra. will try to time the precip east across the
remainder of the area. expect keri to remain dry till late
afternoon. warmer and more humid air will arrive behind the front
and expect widespread ifr cigs and vsbys to develop as the snow
continues to melt. little improvement is expected till a cold
front arrives later tonight. it appears that a line of convection
will develop ahead of the front and move across the local area
beginning later this evening. will not include any thunder in the
tafs for now...but thunder is certainly a possibility...especially
in the south.
the other big concern today is the winds. se flow will gradually
increase today and then become s toward evening. the flow will
become sw behind the cold front. gusts to 30 knots are likely by
late afternoon most areas with gusts to 40 knots or greater with
any convection that forms and also right behind the cold front.
keri will see a good set up for down sloping winds and gusts to 40
knots are possible there by late afternoon.
outlook...non-vfr ne oh/nw pa friday and maybe sat in -shsn. some
non-vfr possible again sunday and maybe snowbelt on mon.

marine...
jet maximum is progged to move northeast across the southern great
lakes and this feature will likely cause winds to increase over
the lake friday morning and continue into friday evening. winds
are expected to reach gale force friday morning. coordinated with
surrounding offices and the canadians on issuing the gale warning
for lake erie. warning will go into effect 7 am friday morning
through 1 am saturday morning.
previous discussion...
a strong cold front is still on track to cross the lake later
tonight. will see increasing se flow today and s flow tonight ahead
of the front. sw flow behind the front will increase to gale force
on friday. have trimmed the watch start time back several hours.
it still a little far out to hoist the gale. have coordinated with
buffalo and expect the day crew to go with a warning. speeds will
gradually diminish friday night. west to southwest flow will then
continue through the end of the period. a line of convective
showers will likely cross the lake tonight. expect gusts with the
line to be close to gale force.

the national weather service in cleveland has issued a

flood advisory for rain and melting snow in...
lucas county in northwest ohio...
ottawa county in northwest ohio...
northern wood county in northwest ohio...

until 630 pm est

at 1224 pm rain and thunderstorms continued across parts of
northwest ohio. snow melt was also occurring. flooding and ponding
of low lying areas and poor drainage areas was reported. the
flooding was exacerbated by drains that were plugged with snow and
ice.

flooding of low lying and poor drainage areas will likely continue
this afternoon.

precautionary/preparedness actions...

excessive runoff from the rain and snow melt will cause minor
flooding of low lying and poorly drained streets...highways and
underpasses. minor flooding of low lying roads and farmland near
creeks...streams...and drainage ditches is also likely. never cross
a flooded roadway.

area forecast discussion
national weather service cleveland oh
353 pm est thu feb 20 2014

synopsis...
deepening low pressure over the mid mississippi valley will cross
the western great lakes tonight and move across ontario on friday.
the warm front will move north of the area this evening followed
quickly by the cold front tonight. a weak cold front will cross
the area on saturday. colder air will spread across much of the
plains and midwest and lower great lakes early next week.
&&

near term /until 6 am friday morning/...
the last of the rain (the first batch) is lifting north across lake
erie. all of our meso models redevelop showers across western ohio
late this afternoon and early this evening but the better action is
showing across the mississippi valley as thunderstorms are already
racing northeast. this activity will get drawn north quickly
ahead of the front. not sure how much thunderstorms will get this
far north but there certainly is a chance given the low level jet
and the elevated instability. there is probably a better chance
for a quasi linear convective system (qlcs) of gusty showers just
ahead of or aligned with the cold front. these lines commonly
produce strong to damaging wind gusts. our synoptic models have
difficulty generating enough instability with the cold ground and
shallow inversions but when push comes to shove we can usually get
these winds to mix down with the frontal passage. the south winds
can mix down enough to catch down slope areas and hilltops as
well...especially near the lake erie lake shore. a wind advisory
remains in effect tonight and if necessary we will issue severe
thunderstorm warnings if we get a convective line.
the models will also struggle with the warm advection. just because
we have been slow to warm up during the day...we will get into the
south flow tonight ahead of the front. temperatures are in the 60s
across southern ohio during the afternoon and some parts of
northeast ohio will likely see 60f for an hour or two tonight ahead
of the cold front. the snow has been absorbing much of the rain and
will do so until the dew points rise tonight. then then snow pack
will begin to release all of its water. this will essentially cause
a flash melt of the remaining snow. depending on the amount of
additional qpf...which depends on the thunderstorms...we will see at
least minor to moderate flooding on many waterways. ice jam flooding
will almost certainly occur in some spots and exacerbate the
flooding. residents need to be on alert tonight. the flood watch
will remain in effect.
temperatures by morning should be back down into the lower 30s
across the i-75 corridor to the upper 30s/40 near the pa/oh
border.
&&

short term /6 am friday morning through sunday night/...
subsidence and pressure rises will move across the area on friday.
850 mb winds are progged about 45 knots. we could essentially mix
all of that down. will be close to high wind warning criteria
(50kts/58mph) across northwest ohio. we will certainly see advisory
wind gusts and it will likely be high end across northwest ohio and
near the lake erie lake shore. temperatures will sneak back up to the
lower/mid 40s on friday.
the next cold front is due on saturday. the models have been
consistent posting a little qpf with the front. will keep a low pop
chance for a few rain/snow showers. much the same on sunday. some of
the models develop just enough frontogenesis that i will keep a
small chance of snow showers. none of it should be a big deal. highs
still near 40 on saturday. colder by sunday with highs in the upper
20s to mid 30s on sunday.
&&

long term /monday through thursday/...
broad trough extending across the eastern two thirds of canada and
the northern united states will allow a vigorous positive vorticity
maximum to race east across the forecast area monday into monday
night. this feature will cause a low level jet to develop and move
through the area and would expect some jet dynamics to help enhance
the threat for some light snow. vorticity maximum pulls out to the
east and upper level trough will begin to flatten somewhat and allow
very weak ridging to move into the area by wednesday.
surface high pressure will move east across the ohio valley on
wednesday into wednesday night and bring some fair weather and drier
air back to the region. there is the possibility that flow could be
favorable for some lake effect snow in the northeast tuesday night
into wednesday night and then ending for thursday.
cold air advection returns and this will plunge temperatures back to
the below normal readings we have been seeing all winter. the upper
level pattern is relentless and shows no sign of breaking through
next weekend. actually...upper level ridge is expected to amplify
over the central united states and this will likely cause the trough
over the eastern united states to strengthen and cause deep south
cyclogenesis to occur. will have to monitor this to see if the storm
system takes a bit further north track into next weekend.
&&

aviation /18z thursday through tuesday/...
first batch of moderate to heavy rain and occasional rumble of
thunder continues to lift northeast at this time. models indicate
we will see a dry slot for a period of time with a few scattered
areas of sprinkles or showers through the afternoon. then...as
cold front sweeps through the area this evening...we should see
another shot of precipitation and lower ceilings. gradual
improvement in ceilings and visibilities will take place behind
the cold front. i decided to leave thunder out of the tafs with
the frontal passage since it should be very limited at this time.
problem of the day will be the wind as a low level jet stream
broad maximum moves northeast into the lower great lakes. winds
will be gusty out of the southwest at up to 20 gusting to 30 knots
across the area. this should cause issues with mechanical
turbulence at the taf sites through the end of the period.
outlook...non-vfr ne oh/nw pa friday and maybe sat in -shsn. some
non-vfr possible again sunday and maybe snowbelt on mon.
&&

marine...
gale warnings remain in effect for tomorrow into tomorrow night as
low level jet pushes east into the region behind the cold front.
winds should diminish fairly quickly late friday night into
saturday. the flow will remain relatively quiet through sunday and
then increase in speed on monday but diminish fairly quickly monday
night into tuesday.
