Area Forecast Discussion
National Weather Service Cleveland OH
546 PM EDT Mon May 21 2018

.SYNOPSIS...
High pressure over the Lake Huron will move off the New England
Coast overnight. This will allow low pressure to track NE across
the Lower Lakes Tuesday. High pressure will build in Wednesday
and linger through the end of the work week.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
Issued a severe thunderstorm watch for the southwest corner of
the forecast area until 11 PM this evening. This includes
Hancock, Crawford OH, Marion, Morrow, and Wyandot Counties.
Thunderstorms continue to develop and move northeast toward the
area this evening. Will continue to monitor for severe potential
as the evening progresses. There is the possibility that the
severe threat could extend further northeast overnight. Made
some adjustments to weather to account for severe threat and
also to hourly temperatures to reflect transition of the
warm front lifting north across the area.

Previous Discussion...

Showers and thunderstorms near the IN/OH border will intensify and
move across the forecast area this evening, ahead of approaching low
pressure system.  SPC has most of area in marginal risk with area SW
of FDY-MFD-MT Vernon line in a SLT Risk.  Low pressure West Central
IL will track into the Central Lakes overnight, lifting a warm
front, now across Central Ohio, across the forecast area.   Dew
points south of the front in the lower 60s so capes will approach
1000 j/kg across the southern portion of the forecast area this
evening. Combined with approximately 30 knots of shear and some
lift from 300mb jet will be enough to sustain convection
tonight. Setting up to be a marginal wind event, but with the
warm front cant rule out the chance of an isolated tornado.

Low forecast to be SRN Lower Michigan by daybreak with cold front
extending into SERN IL.   The front will track east dragging the
cold front across the forecast area tomorrow. showers will
linger across the east half of the area tomorrow morning. The
potential for more convection tomorrow afternoon/evening will
depend upon how much debris clouds insulate area tomorrow
afternoon. Everything should move east of the forecast area by
tomorrow evening, as high pressure builds in from the West.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
High pressure will expand south into the Great Lakes region on
Wednesday, slowly shifting to the Mid-Atlantic through Friday. Dry
conditions with low humidity expected Wednesday and Thursday before
dewpoints starts to creep back up with southwest flow on Friday.
Some clouds may linger into Wednesday morning but will scatter out
through the afternoon with increasing subsidence. Temperatures will
drop back a few degrees across the eastern half of the area on
Wednesday into the lower 70s, with mid 70s still likely in the west.
A warming trend will resume on Thursday with lots of sun and heights
building aloft. By Friday most of the area will be in the 80s except
for the northeast lakeshore. Raised highs on both Thursday and
Friday but they may even need to go a little higher.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
Models indicate that we should be between storm systems Friday
night. A weakening cold front will settle into the central Great
Lakes on Saturday with an increased chance of thunderstorms,
especially Saturday evening into Sunday. Models are struggling with
how far south the frontal boundary will move on Sunday. By Monday
the boundary will be lingering over Ohio with an increase in Gulf of
Mexico moisture a possibility. We will watch this potential over the
next week.

Saturday looks to be the warm day of the long term with most
locations warming into the 80s. Still warm on Sunday but with
increased cloud cover near the frontal boundary highs should range
from the mid to upper 70s north to around 80 south. Cooler Monday
with highs range from the upper 60s NW PA to the upper 70s NW OH.

&&

.AVIATION /18Z Monday THROUGH Saturday/...
A warm front across southern Ohio will lift across the forecast
area late this evening. Timing of convection appears NW OH late
this afternoon, then moving east of the forecast area toward
midnight local.

OUTLOOK...Non VFR probable in showers and thunderstorms Tuesday,
mainly across eastern sites.

&&

.MARINE...
Aside from the potential for thunderstorms tonight and again over
the weekend, generally good marine conditions expected on Lake Erie
this week. Northeast winds of 5 to 15 knots are in place across Lake
Erie this evening but will shift to the south overnight as a warm
front lifts north of the lake. Winds will shift to the north late
Tuesday as low pressure moves to the east and pulls a cold front
south behind it. High pressure will expand across Lake Erie on
Tuesday, pulling a weak cold front back south. High pressure will
build southeast into the Great Lakes region Wednesday then to Mid-
Atlantic coast through Friday. A cold front will sink south across
the lake over the weekend. &&
