.SYNOPSIS...
Dry conditions are expected to continue through Saturday with low
precipitation chances possible Sunday into early next week. Although
a low chance for rain is in the forecast early next week, rainfall
amounts look to be light. Above normal temperatures are expected to
continue this week into early next week. A wetter and cooler pattern
is favored toward midweek and beyond of next week.
&&
.NEAR TERM /THROUGH TODAY/...
A stagnant weather pattern remains entrenched across the Ohio
Valley, particularly through the near and short term periods as
midlevel ridging provides dry and unseasonably warm conditions with
below normal PWs. Temps in the mid to upper 50s at daybreak will top
out in the upper 80s to near 90 degrees late afternoon amidst
plentiful sunshine. A few afternoon Cu are expected once again, but
sunny to mostly sunny skies will prevail.
Minimum RH values will dip to near 30% mid to late afternoon,
particularly in central OH. But light WNW winds around 5kts should
inhibit fire spread concerns.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM FRIDAY/...
More of the same is on tap for the short term period with clear skies
persisting tonight into the day Friday, with just a few afternoon
Cu. Some deeper/better moisture will slowly encroach from the W
Friday night into this weekend, leading to a bit more in the way of
cloud cover.
Temps tonight dip into the mid to upper 50s from E to W, respectively,
before rebounding to around 90 degrees area-wide Friday. Minimum RH
values around 30% are expected again late Friday afternoon amidst
light sfc flow.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Complex synoptic pattern begins to unfold this upcoming weekend into
the following work week. To start, a negatively tilted H5 ridge is
stretched across the eastern CONUS. The Ohio Valley remains on the
western periphery of this ridge, with mid-level troughing in close
proximity as the trough remains aligned across the Upper
Midwest/Plains region. Model guidance has trended towards a drier
forecast for the weekend as the base of the trough struggles to
swing through the fa. Sunday will certainly have better chances for
a stray shower compared to Saturday as this trough closes in even
further, but PoPs on Sunday still generally remain in the 20-30%
range, with these chances mainly occurring after sunset.
Meteorological pattern becomes more unsettled next week as this H5
trough slowly carves its way through the central CONUS. Some model
guidance hints at a potential closed low developing as well, which
would keep this unsettled weather pattern around for a longer
stretch. Thus, expect the potential for multiple rounds of rainfall
next week, especially if there is more of an eastward progression in
the placement of the base of this trough and associated upper low.
Seasonably warm temperatures will persist through much of the
extended forecast period. However, there will be a decreasing
temperature trend by the middle of next week as the Ohio Valley
receives more influence from the trough.
&&
.AVIATION /06Z THURSDAY THROUGH MONDAY/...
VFR conditions are expected through the TAF period, with a very dry
air mass in place. The only exception will be some brief MVFR VSBY
(with low confidence in IFR or lower) at KLUK around daybreak due to
BR.
SKC will prevail before a FEW VFR Cu develop again this afternoon,
with winds remaining near 5kts or less through the period.
OUTLOOK...Thunderstorms are possible on Monday.
