Area Forecast Discussion
National Weather Service Wilmington OH
339 PM EDT Fri Sep 21 2018

.SYNOPSIS...
A strong cold front will push southeast through the region
tonight. The front will then stall across the Tennessee Valley
while high pressure moves across the Great Lakes through the
weekend. Much cooler weather can be expected this weekend.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
It appears that the main convective line to affect the region
this afternoon and this evening is developing from near
KCLE...southwest to KDAY...then into the Tri-State region (a
prefrontal trof/low level convergent axis) This line, broken in
spots, may produce strong to severe storms given moderate
instability, sufficient effective shear, DCAPES 1000+ J/kg, and
delta theta e over 20 K. Likely PoPs have been employed to
account for this. A cold front will then move southeast through
our region tonight, with the pcpn threat ending behind its
passage. Much drier and cooler air will move in overnight. Lows
will range from the lower 50s north to around 60.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
Aforementioned cold front will stall out in the Tennessee Valley
Saturday into Saturday night as it becomes parallel to the mid
level flow. Considerable mid and high level clouds can be
expected in the southwest flow aloft, enhanced by an upper level
jet across the Great Lakes. Models continue to indicate that
weak embedded energy will move across the Ohio River Valley
Saturday afternoon into Saturday night. In addition, they also
suggest that some low to mid level deformation may develop along
and south of the Ohio River. This setup will bring a chance of
rain to these locations, with the remainder of the region
remaining. Dry. Have kept PoPs in the chance category, but some
likely PoPs may be needed across our far southeast CWFA if
models continue to trend wetter. It will be much cooler on
Saturday due to low level CAA, clouds, and northeast surface
flow. Highs will only warm into the mid and upper 60s. Lows
Saturday night will range from the mid 40s far northwest to the
mid 50s along and south of the Ohio River.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Westerly mid level flow with east-west quasi-stationary front to our
south across the TN Valley late this weekend. Deepest moisture and
instability to our south but model solutions continue to indicate an
overrunning situation with ILN/s southern FA on the northern
periphery of rain shield. Will carry a low pop chance of pcpn
generally along and south of the Ohio River Sunday. Cool
temperatures to continue with highs Sunday around 70.

Models continue to be in general agreement with long wave trough
developing over the nations mid section early next week. Flow backs
southwesterly and moisture spreads back north across the area with
initial weak shortwave lifting through the area Monday. Will
continue to allow low pop chances for a shower into the south late
Sunday night.

Front to lift back north as a warm front Monday/Monday night with
pcpn chances increasing and some marginal instability developing
mainly in the west. Will spread chance pops across the area and
include the mention of thunder. Temperatures will warm with highs
Monday from the lower 70s northeast to the mid 70s southwest.

A surface cold front to push across the area late Tuesday night into
Wednesday. Will ramp pops up to likely category with the approach of
the front Tuesday night. In the warm sector temperatures look to be
above normal with highs Tuesday from the mid 70s north to near 80
south.  Due to the high amplification of the mid level pattern,
prefer a slower frontal movement with precipitation lingering on
Wednesday. Precipitation, clouds, and frontal passage will result in
cool temperatures a little below normal. Highs Wednesday to range
from the upper 60s northwest to the lower 70s southeast.

Model solution spread leads to lower confidence toward the end of
next week. Will keep Thursday mainly dry with high pressure building
across the area. Expect temperatures a little cooler than normal
with highs Thursday from near 70 northwest to the lower 70s
southeast.

Another cold front to push across the area Friday. With timing and
placement differences will limit pops to slight chance during the
daylight hours.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
A strong cold front will move southeast through the Great Lakes
and Ohio Valley this afternoon into tonight.

A relatively tighter pressure gradient associated with the
approaching front, along with mixing stronger winds aloft, will
keep south to southwest winds gusty through much of the
afternoon. Winds will gust between 20 knots and 30 knots.

Otherwise, showers and thunderstorms are forecast to develop
along and ahead of the cold front as diurnal instability
combines with low level convergent forcing. Have continued with
TEMPO MVFR conditions in TSRA at all terminals. As usual, there
will be pockets of IFR visibilities in the stronger storms.

Showers and storms will be exiting the terminals this evening,
allowing drier conditions to move in on northerly winds. VFR
conditions are expected.

On Saturday, aforementioned frontal boundary will have stalled
in the Tennessee River Valley. Some weak upper level energy
along with lower to mid level moisture may result in a chance
of light rain near and south of the Ohio River during the
afternoon. Conditions should still remain VFR for all locations.

OUTLOOK...Thunderstorms possible Monday through Wednesday.
