.SYNOPSIS...
A strong cold front will pass east of the area through this evening.
A Canadian airmass with strong high pressure returns to the region
for Wednesday and will persist through the weekend.
&&
.NEAR TERM /THROUGH WEDNESDAY NIGHT/...
Showers have been more persistent across eastern portions of the
forecast area today while Northwest Ohio has seen a good break in
the rain. A swath of heavier rain moving out of Central Ohio will
continue to move northeast towards Youngstown and Meadville late
this afternoon. A dry slot is evident on satellite imagery
across the west with just a few scattered showers located along
the cold front that extends from just east of Port Clinton to
Findlay at 3 PM. Overall expecting shower activity along the
front to increase in coverage late this afternoon and this
evening as shortwave energy and upper level support increases,
especially along and east of the I- 71 corridor this evening.
Low level forcing along the front is also forecast to increase,
although perhaps a little slower than forecast to fill back in.
Instability has been limited thus far with ML CAPE of 500 J/kg
or less with extensive cloud cover but a chance of thunderstorms
does remain through this evening. Additional rainfall amounts
in the east will tend to range from a half inch to an inch with
locally higher amounts possible.
An abrupt wind shift to the north will accompany the front and
precipitation will taper off across most of the area by midnight.
Temperatures at 850mb fall by approximately 8C overnight,
ushering in a much different airmass. Upper level trough axis
will be overhead at 12Z and generally east of the area by 18Z.
Low level cyclonic flow in the morning will transition to anti-
cyclonic flow as strong surface high pressure over Wisconsin
builds into the Central Great Lakes. Expecting scattered cloud
off Lake Erie despite the anti-cyclonic flow given favorable
lake to 850mb delta T of around 19C. Highs on Wednesday will
tend to feel more fall like with highs in the 50s to lower 60s.
Following the airmass change, we will encounter much cooler
temperatures on Wednesday night. East northeast flow will keep
temperatures along the lakeshore and in NW Ohio slightly warmer
while the lowest min temperatures are focused across inland
portions of NE Ohio and NW Pennsylvania. Lows in this area are
forecast to reach the low to mid 30s and portions of NE Ohio
and NW Pennsylvania may need a Frost Advisory.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY/...
Strong high pressure continues to build east across the Great Lakes
Region on Thursday, reaching New England by Thursday night.
Temperatures on Thursday will again be below normal with frost
concerns on Thursday night. Winds will be near calm on Thursday
night presenting a more favorable set up for radiational
cooling. Most inland areas are expected to be in the low to mid
30s presenting favorable conditions for frost to form. A few of
the cooler valley locations in NE Ohio and higher terrain in NW
Pennsylvania are forecast to be near freezing and there is a
chance a couple counties could see a freeze.
Otherwise the ridge aloft starts to build again by Friday with
temperatures trending back towards normal.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
The long term forecast begins with some uncertainty as the 12Z ECMWF
and GFS are showing a compact upper level trough diving south into
the Great Lakes region. These solutions are accompanied by surface
low pressure and the potential for some showers. Deterministic
models have shown poor run to run consistency with this feature and
ensembles only show a weak trough which leads to below normal
confidence. Will keep the forecast dry for now over the weekend and
continue to monitor model trends with respect to this trough moving
out of Canada.
A warming trend should resume early next week as a high amplitude
ridge builds in behind this feature. Highs by Monday are forecast to
be near 70 degrees again.
&&
.AVIATION /00Z Wednesday THROUGH Sunday/...
Mixed-bag of VFR, MVFR, and IFR across the TAF sites this
evening, associated with both low ceilings and vsbys from rain.
MVFR/IFR conditions will gradually begin to improve to IFR
through tonight as drier air arrives behind a cold front,
evident by VFR conditions already appearing at TOL. Thunder is
not expected through the rest of this evening and overnight.
Otherwise, a cooler air mass will arrive on Wednesday, with sct
to perhaps bkn lake effect clouds around 3.5kft possible
downwind of Lake Erie.
Winds are out of the north behind the cold front, around 10
knots. Winds will favor a northerly direction through the TAF
period, 7 to 10 knots. Slightly higher winds of 10 to 12 knots
with gusts up to 20 knots are possible at CLE/ERI Wednesday
afternoon.
Outlook...Mainly VFR expected through Sunday.
&&
.MARINE...
Southwest winds 15-20 knots will quickly become northerly behind
the passage of a strong cold front this afternoon and evening.
Higher wind speeds 20-25 knots will be possible across nearshore
zones through Wednesday. Given onshore flow, wave heights will
build to 4-6 feet. As such, a Small Craft Advisory remains in
effect from this evening through Wednesday. Strong Canadian high
pressure will build across the Great Lakes region Wednesday
through the end of the week. This will allow for winds to
decrease and wave heights to subside below small craft criteria
by early Thursday morning. Winds turn northeasterly at 10-15
knots with the arrival of the high Wednesday night into
Thursday. Offshore flow 5-10 knots returns Friday into the
weekend.
