day 1 convective outlook
nws storm prediction center norman ok
0752 am cdt wed may 27 2015

valid 271300z - 281200z

...there is a slgt risk of svr tstms over parts of the oh valley...

...there is a slgt risk of svr tstms from the mid atlantic states
into new england...

...there is a slgt risk of svr tstms over the central and southern
high plains...

...there is a mrgl risk of svr tstms over parts of the central and
eastern us...

...summary...
severe storms are possible today across parts of the northern mid
atlantic coast region into northern new england...as well as parts
of the upper ohio valley and lower great lakes region...and portions
of the central high plains into the southern plains.

...ohio valley...
morning water vapor loops show a shortwave trough moving across
ia/mo. a persistent cluster of thunderstorms is associated with
this trough over southeast mo. early visible satellite imagery
shows relatively clear skies downstream of the convection...which
should allow rapid heating and destabilization. present indications
are that this cluster of storms will intensify by late morning over
southern ind/western ky and track northeastward across oh into
western pa. mlcape values over 1500 j/kg and 40-50 knots of mid
level flow support a risk of locally damaging winds and hail in
these areas.

...mid atlantic region into new england...
a band of showers currently extends from western ny southward into
wv. this weak convection is associated with a lead shortwave trough
that will move eastward into parts of the mid atlantic region and
new england later today. strong heating in this region coupled with
dewpoints in the 60s will help yield mlcape values over 1000 j/kg.
most cam solutions show scattered thunderstorm development along
this corridor by mid afternoon. low level and deep layer shear
profiles are favorable for organized/bowing storm structures capable
of locally damaging winds. any storm that can remain discrete in
this region would pose a marginal risk for a tornado as well.

...central/southern high plains...
strong heating will occur once again today over parts of eastern
co/western ky and southwest neb...southward into tx and western ok.
similar to yesterday...moderate cape values and a breakable cap will
result in isolated to scattered thunderstorms along the dryline.
the highest probability of storms appears to be from southwest neb
into northwest ok. strengthening low level winds this evening and
steep lapse rates will promote a risk of supercells capable of
hail...damaging winds...and isolated tornadoes.

into the evening. high pressure will briefly be located over the
region on thursday but will move off the new england coast early
friday.

&&

near term /until 6 pm this evening/...
update...no changes for the update.
original...a weakening cold front will cross the region late this
afternoon into the evening. the area looks to be dry through the
morning but with afternoon heating and the lift near and ahead of
the front there should be some convective development. some of the
thunderstorms will have the potential to produce some stronger
wind as they cross northern ohio and nw pa. temperatures aloft may
also cool enough to allow for the development of some hail. will
mention the severe potential in the hwo.

it will be another warm day under variable amounts of cloud
cover. most locations should warm into the lower 80s.

&&

short term /6 pm this evening through saturday night/...
cold front should be east of the county warning area near or
shortly after midnight with the thunder moving eastward with it.
high pressure should then take control for about 24 hours with dry
conditions expected thursday into friday. we will have to monitor
nw ohio friday evening to see if any convection can drift into
the region ahead of the next cold front. the main push of
thunderstorms should hold off until saturday afternoon and
evening. these thunderstorms will again have a chance to become
severe.

temperatures will only cool slightly for thursday in the wake of
the weak front. most locations will be within a couple degrees of
80. cooler near the lakeshore with a lake breeze developing.
friday will see highs return to at least the middle 80s. a few
degrees cooler on saturday with more cloud cover.

&&

long term /sunday through tuesday/...
trend continues for saturdays cold front to be south of the area by
sunday. have therefore trended precip chances down...but still left
some as there are still discrepancies on how far south it gets. at
any rate it will be much cooler with high pressure building to our
north and northerly flow across our area. fair weather and high
pressure by tuesday with highs slowly trending warmer. overall
though temperatures near seasonal averages.
