.SYNOPSIS...
A weak system will move through tonight. Another system will
move through tomorrow afternoon into the evening hours and will
usher cooler air into the region.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A system is approaching and moving into Indiana. There is a lot
of dry air in place and therefore not expecting much if any in
the way of precipitation. Have a chance of sprinkles mention in
across northern portions of the region as this moves through.
Since this system is encountering dry air there have been an
increase in wind gusts ahead and with this system. An inversion
will set up this evening, however still expect that there will
be some wind gusts. Temperatures overnight will only drop into
the upper 40s to the 50s. Went close to guidance for low
temperatures overnight.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Another system will move through Wednesday into Wednesday
evening. Winds will once again gust with this system. Cannot
rule out a thin line of showers with this feature, however at
this time limited mention to sprinkles due to dry air and
uncertainty with precipitation measuring. While temperatures
will rise into the upper 60s to middle 70s, as the cold front
moves into the region temperatures will begin to drop. By
Thursday morning temperatures will drop into the 30s across most
locations.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
High pressure moves across the Ohio Valley on Thursday bringing
fall- like conditions under mostly clear skies. The surface
high quickly shifts east on Thursday night ahead of a low
pressure system approaching from the west.
On Friday, rain chances increase as a warm front moves through
in the morning followed by a cold front in the afternoon/evening
while the low progresses across the region. Overall QPF is
fairly low and some locations may not see any rainfall at all.
Overall forcing and moisture return are not that strong.
High pressure builds in behind the cold front for the weekend
allowing for a return of fall temperatures to the Ohio Valley.
The cool down will be brief however since high pressure quickly
shifts east by Monday which will allow above average
temperatures and southerly winds to return.
&&
.AVIATION /23Z TUESDAY THROUGH SUNDAY/...
VFR conditions are expected through the TAF period.
For tonight, a mid level disturbance will quickly lift
northeast across the central Great Lakes. Some SCT to local BKN
mid/high clouds will accompany this system across the region.
Could be an outside chance of a sprinkle early on near the KDAY
terminal. Winds will be from the south between 5 and 15 knots
(strongest north of the KDAY/KCMH/KLCK terminals). A modest low
level jet pivoting across the area will bring a period of non
convective LLWS. This should shift east and dissipate around
13Z.
On Wednesday, a mid level trough will dig southeast into the
Great Lakes. This will be accompanied by a cold front. The front
is moisture starved and thus expecting mainly mid and high
level clouds, although a few high based cumulus clouds could
form near and behind the front. Winds will increase and veer
from the southwest to the northwest as the front passes.
Sustained winds will increase between 12 and 16 knots with gusts
up to 25 knots.
For Wednesday night, skies will clear and winds will diminish
and become northerly.
OUTLOOK...MVFR conditions possible Friday into Friday night.
