roadways or minor flooding. one to two inches of rainfall is
possible through tonight. storm motion will be to the northeast at
around 20 mph.

a few thunderstorms today could have strong gusty winds approaching
severe limits.

.days two through seven...sunday through friday

low pressure will track northeast along a stalled frontal
boundary on sunday bringing another round of rain. this rainfall
could cause additional ponding of water and minor flooding of
poor drainage areas.

there will be a high risk or rip currents along the lake erie
shoreline on saturday.

.spotter information statement...

spotter activation is not expected through tonight.

area forecast discussion
national weather service cleveland oh
509 am edt sat may 30 2015

synopsis...
moisture will spread north across the area today and interact with
a cold front approaching from the north. this frontal boundary
will stall in the vicinity of lake erie overnight with a wave of
low pressure tracking northeast along the boundary on sunday. the
front will push south on sunday night with high pressure building
overhead on tuesday.

&&

near term /until 6 pm this evening/...
the forecast area remains in the warm sector ahead of a cold front
approaching from the north. water vapor imagery shows a potent
upper level trough pushing south across ontario while a plume of
moisture can be seen spreading north up the mississippi valley.
this moisture which is just starting to sneak into nw indiana will
be directed eastward with time as the trough pushes south this
afternoon. the surface front itself will be slow to arrive...but
moisture will increase this afternoon and some leading energy or
even remnant support from upstream convection will help to
initiate convection this afternoon. some of the high resolution
models seem a little too fast with activity developing this
afternoon and think activity will follow more of a diurnal
cycle...increasing in coverage this afternoon. pw values are
forecast to increase to around 1.70 inches as the deeper moisture
arrives. instability may be a little better out ahead of the front
where there may be more sun. models showing around 1000 j/kg of
ml cape developing this afternoon and expect the greatest coverage
of thunderstorms to be focused from northwest ohio...extending ne
towards cleveland and erie by this evening. storm motion today
will be to the ne at about 20 knots which will could result in
some training of storms. due to the threat of training...moderate
storm motion and enhanced precipitable water values...expecting
some thunderstorms to produce locally heavy rainfall. the coverage
of the more robust convection is still somewhat hard to determine
so did not want to go with any flood watches...but will need to
keep an eye on rainfall this afternoon/evening. added a mention of
heavy rain possible with thunderstorms to the favored areas. the
storm prediction center also has the area in a marginal risk for
severe storms with wind gusts being the primary threat. this would
be mainly in the form of a wet microburst with limited
organization today. one question will be if it tends to propagate
to the south with time towards the better instability so that will
be something to watch which may help reduce training. warm mid-
levels may limit the southward progression though.

&&

short term /6 pm this evening through tuesday night/...
convection will likely continue into the evening with a decreasing trend
as we lose diurnal support...before the next wave rides north
along the front on sunday. this should place a swath of rain on
the northwest flank of the low with thunderstorms possible in the
east ahead of it. did raise temperatures in ne ohio and lower them
towards toledo. models are placing a 1.50-2.00 maxima of rain to
the north of the storm track but this may end up clipping
northwest ohio and then largely passing north of our area.
depending on how much rain we receive today...we may need to
consider a flood watch for sunday if a secondary round of heavy
rain is expected. a limiting factor for the heavy rain could be
the intrusion of a mid-level dry slot as seen on the gfs so we are
still trying to pin down the track of the highest qpf.

the front will eventually be pulled south behind the departing
wave on monday evening with any lingering precipitation becoming
light. much cooler temperatures expected on monday with highs
struggling to reach the low 60s. high pressure will build
southeast overhead on tuesday with partly to mostly sunny skies
helping temperatures recover to the 70s except 60s near lake erie. a
complicated forecast is expected this period trying to time the
convective development ahead and along a cold front for saturday
and the development and movement of a wave on the stalled front
south of the region sunday into monday.

&&

long term /wednesday through friday/...
in general...the models
have upper ridging over the area until late fri when a weak trough
is shown moving east thru the lakes. dry air is in place on wed then
by fri enough moisture appears to have moved back into the area for
sct shra/tsra to develop. near normal temps on wed should increase
to above normal by fri as east winds turn south.

&&

aviation /06z saturday through wednesday/...
some patchy mvfr fog may develop toward daybreak for a few hours
otherwise vfr will prevail with patches of higher clouds and
widely sct shra the rest of the night.

the approach of a cold front will trigger sct shra/tsra to develop
on sat...mainly in a west to east fashion. the short term models
indicate that a band of convection tries to develop near cle around
13 to 14z then pushes east into nw pa thru 17z. this may be
something to focus on but for now will keep tafs broad-brushed but
by mid to late afternoon...the storms should become numerous and
continue thru 06z. the cold front should drop se across most of the
taf sites by 06z causing sw winds of 10 t0 20 knots to turn nw to
north at 5 to 15 knots.

outlook...non vfr possible likely sunday.

&&

marine...
a cold front will drop se across lake erie this evening
causing sw winds of 10 to 20 knots to shift to nw then ne and
increase to 15 to 25 knots for sunday. numerous tsra will occur with
the frontal passage so beware. a sca will likely be needed for the
end of tonight thru sun eve. winds and waves will gradually diminish
sun night into tue as high pressure pushes into the lake. the high
should provide light e to ne winds on wed as it begins to shift east
of the lake.

&&

cle watches/warnings/advisories...
pa...none.
ny...none.
marine...none.

Beach Hazard Statement
Statement as of 4:19 AM EDT on May 30, 2015

... Beach hazards statement in effect from 2 PM EDT this afternoon
through Sunday afternoon...

The National Weather Service in Grand Rapids has issued a beach
hazards statement for dangerous swimming conditions... which is in
effect from 2 PM EDT this afternoon through Sunday afternoon.

  • High wave action... strong currents and dangerous swimming
    conditions expected.
  • Strong structural currents expected.
  • Strong longshore currents expected.
  • Rip currents expected.
  • Location... beaches from St. Joseph to Manistee.

For north flow use:

North Beach in South Haven...
Holland State Park...
Muskegon State Park...
Mears State Park in Pentwater...
Stearns Park in Ludington.

  • Overview/potential impacts... winds will become north to
    northeast this afternoon at 15 to 25 knots and continue through
    most of Sunday. This will build waves to between 4 to 7 feet.
    These conditions in combination with the very cold water will
    make being in the water hazardous.

Precautionary/preparedness actions...

High wave action makes swimming difficult and can tire even a
strong swimmer quickly.

Structural currents form along piers where longshore currents and
wave action flow into the structure. Structural currents can
sweep you out into deeper water along the pier structure.

A longshore current is a lake current that moves parallel to
shore. Longshore currents can be strong enough to prevent
swimmers from being able to keep their feet on the bottom...
making it difficult to return to shore.

Rip currents are powerful channels of water flowing quickly away
from shore... which occur most often at low spots or breaks in
sandbars. Rip currents can sweep you into deeper water.


Nothing to be alarmed about. Just a neat-looking radar image from 1:40 p.m. today.


Side note: some areas could see a good bit of rainfall over the next 24 hours.

This Afternoon: Showers and thunderstorms likely, mainly after 3pm. Mostly cloudy, with a high near 80. West wind around 10 mph. Chance of precipitation is 60%. New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms.

Tonight: Showers and thunderstorms before 1am, then showers and possibly a thunderstorm after 1am. Some of the storms could produce heavy rain. Low around 53. Northeast wind 8 to 16 mph. Chance of precipitation is 100%. New rainfall amounts between 1 and 2 inches possible.

Sunday: Rain and possibly a thunderstorm, mainly before 4pm, then a chance of rain and thunderstorms after 4pm. High near 55. Breezy, with a northeast wind 21 to 23 mph. Chance of precipitation is 90%. New rainfall amounts between a half and three quarters of an inch possible.

...flood watch in effect through sunday afternoon...

the national weather service in cleveland has issued a

  • flood watch for a portion of northwest ohio...including the
    following areas...lucas...ottawa and wood.
  • through sunday afternoon
  • showers and thunderstorms with very heavy rainfall are expected
    to move across the watch area tonight through sunday. widespread
    rainfall amounts of 1 to 2 inches are possible with isolated
    higher amounts.
  • the impacts are expected to remain in small streams and urban
    areas. these thunderstorms have the potential to produce
    torrential downpours with very high rainfall amounts in a short
    time. this type of rain can easily overwhelm poor drainage and
    urban areas.

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

0623 pm cdt sat may 30 2015

areas affected...eastern illinois...much of indiana...much of
ohio...western pennsylvania...and far southwestern new york

concerning...severe potential...watch unlikely

valid 302323z - 310030z

probability of watch issuance...20 percent

summary...scattered bands of thunderstorms will continue to produce
isolated severe wind/wind damage. a ww is unlikely due to the
isolated nature of the threat.

discussion...bands of newd moving strong to isolated severe storms
will continue through the discussion area over the next couple of
hours. isolated damaging wind gusts remain the primary threat with
these bands...particularly in/near localized bowing segments and
along leading edges of newd-propagating cold pools. weak to moderate
instability and deep unidirectional swly flow aloft should help
maintain storms as they move to the northeast...possibly as far as
western pennsylvania by sunset. the threat is expected to gradually
lessen with time with the loss of daytime heating after about
01-02z. given the isolated nature of the threat...a ww is not needed
at this time.
