Drier and cooler weather will move into the region today in the
wake of a cold front. High pressure will then settle across the
Ohio Valley by Monday. The high will continue to influence the
region`s weather into Tuesday. Mostly sunny, warm days followed by
cool and clear nights can be expected through early week. Warmer,
more humid weather, along with a threat for showers and
thunderstorms, will return mid to late week as a cold front
approaches the region.
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A cold front will move through the region this morning. There
could be some scattered shower activity along and ahead of the
front, mainly across our se CWFA through mid morning. Otherwise,
skies will gradually clear from west to east, with mostly sunny
skies expected for all locations by early afternoon. Current
satellite and observations confirm that clearing is occurring as
expected. An embedded disturbance moving through a mid level
trough across the Great Lakes should stay to our north this
afternoon into this evening, keeping associated scattered
showers/storms to our north. We may see some increased cloud
cover, however, over the northwest zones late in the day. Highs
will range from the upper 70s to the lower 80s with much lower
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
High pressure to our west will move east, settling across the
Ohio Valley Monday into Monday night. Skies will clear tonight,
followed by a mostly sunny Monday. Skies will be mainly clear
Monday night. Lows tonight will range from the mid to upper 50s.
Highs on Monday will range from the upper 70s to the lower 80s
once again. The coolest readings are expected Monday night with
clear skies and light to calm winds, providing excellent
radiational cooling conditions. Lows will be in the lower to mid
The center of high pressure will move toward the Atlantic seaboard
on Tuesday. However, surface ridging will still extend back into
the Ohio Valley. Mostly sunny skies are forecast with airmass
modfication occurring. After a cool start, highs should warm into
the lower and mid 80s.
For Tuesday night into Wednesday, return flow will develop between
high pressure to our east and a slow-moving cold front to our
west. This will begin the process of increasing low level moisture
back into the region along with an increase in clouds. Partly
cloudy skies and highs in the mid to upper 80s are expected on
Wednesday. Will maintain a chance for some showers and
thunderstorms as we head into Wednesday night as deeper moisture
along with some lift due to waa occurs ahead of the slow-moving
.LONG TERM /THURSDAY THROUGH SATURDAY/...
A better chance for showers and thunderstorms will occur Thursday
into Thursday night as the cold front pushes southeast across the
area. Warm and humid weather will continue with highs in the mid
and upper 80s.
High pressure and a drier airmass will build back into the area
behind the front for Friday and Saturday. Highs for Friday and
Saturday will be in the upper 70s to lower 80s.
.AVIATION /18Z SUNDAY THROUGH THURSDAY/...
-- Changed Discussion --Expect VFR to persist through the forecast period, except at KLUK
where BR may reduce visibility early Monday. Otherwise, high
pressure and anticyclonic subsidence in a drying airmass will
result in mainly clear skies. Sky cover will consist of FEW to SCT
cumulus and cirrus. Winds will gust close to 20 knots out of the
west for the rest of the afternoon before subsiding to under 10
knots this evening. Look for northwest winds around 5 knots on
Monday under the center of the surface high.
OUTLOOK...Showers and thunderstorms are possible on Thursday.
