Hazardous Weather Outlook-2

hazardous weather outlook
national weather service cleveland oh
543 am edt wed jun 23 2010
this hazardous weather outlook is for lake erie...north central
ohio...northeast ohio...northwest ohio and northwest pennsylvania.
.day one...today and tonight.
there is a moderate risk of severe thunderstorms across northern
ohio and northwestern pennsylvania this afternoon into tonight.
the main threat will be strong damaging winds. however marginally
severe hail will be possible.
a warm front lifting across northeast ohio and northwest
pennsylvania may generate enough lift to cause thunderstorms to
develop during the early afternoon. if any isolated supercell
thunderstorms can develop in this area there is a small potential
for the development of a tornado.
elsewhere across the region a warm and moist airmass will be in
place. as temperatures approach 90 degrees the airmass will become
increasingly unstable. while warmer temperatures aloft are expected
to move into the area it may not be enough to suppress thunderstorm
development...especially if any outflow boundaries move into northwest
ohio from morning thunderstorms over michigan.
additional strong to severe thunderstorms may also develop along a
cold front that will sweep across the region during the overnight hours.
.days two through seven...thursday through tuesday.
no hazardous weather is expected at this time.

il...extreme nrn ind...much of lower mi and extreme nw oh...
...there is a slgt risk of svr tstms from wrn new
england/mid-atlantic region swwd into the srn plains...
...synopsis...
primary feature of interest will be the ejection and amplification
of the upper trough from the nrn plains/upper ms valley into the
lower great lakes region on wednesday. associated surface lows will
track from parts of ia ewd along a nwd developing warm front into
mi/swrn ontario through wednesday evening. a cold front will surge
sewd across the midwest and the cntrl/srn plains by 12z thursday.
...upper ms vly into the midwest/oh valley/great lakes region...
one or more rounds of active severe weather will affect a corridor
from the upper ms valley to the lower great lakes on wednesday and
wednesday night.
first order of business will be the nocturnal mcs/possible derecho
expected to ongoing at 12z wednesday over portions of the upper ms
valley. the forward-propagating mcs is likely to continue tracking
ewd across lake mi and into at least the srn half of lower mi during
the morning then swrn ontario during the afternoon. air mass
downstream will gradually recover in wake of today/s departing
impulse...at least as far n as srn lower mi. as a result...there is
sufficient evidence to expect a continuation of damaging wind risks
during the morning into the early afternoon...although there may be
an initial weakening trend of the activity as it encounters slightly
less unstable regime over the cntrl/lower great lakes.
afternoon attention will focus on the 30-60 meter height falls
associated with the approaching mid-level wave. there is medium to
high confidence that the air mass will recover over parts of upper
ms valley ewd into the central great lakes with an extensive zone of
lower 70s surface dew points anticipated along/ahead of the surface
low/cold front. steepening low-level lapse rates in wake of
dissolving morning cloud cover will boost mlcapes 2000-3000 j/kg and
new storms will develop from srn wi/nrn il by mid-afternoon.
vertical wind profiles will be largely unidirectional...but strong
speed shear will contribute to supercell profiles with large hail
and a few tornadoes likely with initial development. activity will
likely develop upscale into another mcs by evening...tracking ewd
across srn lower mi and nrn ind with high winds. activity may
eventually reach the lower great lakes/upstate ny/wrn new england by
12z thursday with risks for damaging winds as the low-level air mass
recovers rapidly in advance of the mid-level impulse.
farther s...a few thunderstorms are expected to form along the
retreating warm front across parts of the mid/upper oh valley during
peak heating wednesday. these storms will be embedded along the
fringe of 40 kt wly mid-level flow and a modest degree of low-level
turning. as a result...a couple of tornadoes/ damaging wind gusts
will be possible with the storms as they move toward wrn pa during
the evening.
...mid-ms valley to the srn plains...
thunderstorms will likely backbuild swwd along the surging cold
front from the developing great lakes mcs into parts of nrn ok.
region will remain removed from higher momentum aloft...but hot
boundary layer and focus for storms will lead to at least widely
scattered damaging wind/hail possibilities.
...central appalachians to nc...
formidable convectively-enhanced impulse now over the mid-ms valley
will track ese into the central appalachians by 12z wednesday.
storms associated with this feature will turn more sely along the
instability axis into parts of srn va/nc during the day wednesday
with sporadic damaging wind gusts possible.
