.SYNOPSIS...
Cool and dry weather arrives for Friday and Saturday. Warmer air
returns by the second half of the weekend. The chance for showers and
storms returns on Monday to accompany the warmer weather.
&&
.NEAR TERM /THROUGH TODAY/...
Showers continue to dissipate this evening. The system will
gradually push out of the area overnight. Winds will gust around 20
to 25 mph at times through most of the overnight hours. Cooler air
will move into the region with low temperatures dropping into the
upper 30s to the middle 40s across the region. There will be the
potential for a little bit of stratus, especially across northern and
northeastern portions of the area overnight. Do not think fog will
be as much of a concern since winds will stay up some.
During the day on Friday there will be CAA. Although drier air will
be moving into the region, as is typical with these patterns expect
CAA cu to develop during the day before dissipating in the late
afternoon and evening hours. High temperatures will generally only
reach into the low to middle 60s. A few locations north of Columbus
may struggle to make it out of the 50s.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/...
High pressure builds in from the northwest through Friday night. Winds
drop off overnight as high pressure moves closer to the Ohio Valley.
Dry, clear, calm conditions allow lows to drop off into the lower
40s for most locations. Some upper 30s are possible in sheltered
areas.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Surface high pressure will shift east across the Great Lakes Region
through the weekend and off the East Coast by Monday. This will
provide for dry conditions through at least Sunday. As we start to
get into return flow on the back side of the high, we will also see
a warming trend into early next week. Highs on Saturday will be in
the low to mid 70s, increasing to highs in the upper 70s to lower
80s by Monday.
An upper level low over the lower Mississippi Valley will open up as
it lifts northeast across the Ohio Valley through midweek. This
could lead to few showers sneaking into our south later Monday, but
the better chances for showers and thunderstorms associated with
this will be on Tuesday and Wednesday, with likely some diurnal
component to the pcpn chances. Pcpn chances should then taper off
heading into Thursday as the weakening trough axis moves off to the
northeast. Decreasing heights and some pcpn on Tuesday will keep
temperatures down a bit, with highs mainly in the mid 70s. We should
then trend back up in temps through the rest of the long term period
with highs by Thursday into the low to mid 80s.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
Generally VFR conditions are expected through the TAF period. A brief
period of MVFR ceilings will probably reach KDAY in the next few
hours, and there is a low probability of MVFR ceilings at other TAF
sites between now and 12Z as well.
FEW to possibly SCT diurnal cumulus can be expected during the day,
with NNE winds that may gust up to 15-20 knots. Lighter winds and
clearer skies are then expected by late afternoon and early evening.
OUTLOOK...Thunderstorms are possible on Tuesday.
