AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
353 PM EDT Fri Aug 5 2022
.SYNOPSIS...
Warm and humid weather will persist over the Ohio Valley
through the weekend, providing chances for showers and
thunderstorms each day. A cold front will approach the area
early next week with drier conditions for the end of the week.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Weak low pressure will slowly drift east across Indiana
overnight. Deep moisture ushered north ahead of the low will
provide good chances for showers and embedded storms. This axis
is likely to drift east with the low, so best PoPs will continue
this evening into the overnight over northeast KY through south
central Ohio.
In addition to these showers, there will remain an instability
gradient in an arc from east central IN through west central
Ohio this evening where showers and storms did not occur
earlier. Thus, will maintain isolated to scattered coverage of
showers/storms in this area early in the period.
For the overnight, mostly cloudy skies will continue across most
of the local area. Deep atmospheric moisture won't allow
significant cooling of the low-levels; however, can't rule out
some low clouds and patchy fog in locations that receive a bit
more clearing through the night. This will be especially true
west of the I-75 corridor.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
The weak surface low will drift into the region on Saturday.
This will place the axis of deep moisture over the far
southeast, leaving less coverage of clouds and precipitation
northwest of I-71. However, by afternoon, destabilization and
weak convergence near the low will create isolated to scattered
convection. High temperatures will reach the mid-80s in most
locations.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
Area remains in a warm and very moist airmass to start the period.
However, forcing looks to be weak and not particularly organized on
Sunday. So would expect convection to be scattered at most and
primarily diurnally driven. Heights will start to fall on Monday as
a short wave pushes across the Great Lakes. This may result in a
somewhat better chance of showers and thunderstorms during the day.
Another short wave will push southeast across the region late Monday
night into Tuesday and in the process start the carving out a long
wave trough that will then persist through the rest of the week.
Cold front will slide into the northern part of the forecast area
early Tuesday. The boundary looks like it will get hung up across
the area and then not move through until Wednesday afternoon or
evening. Showers and thunderstorms will be prevalent, especially
along and ahead of the front.
High pressure will then gradually build in through the end of the
week.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
Generally VFR conditions will be left behind as much of this
morning's convection subsides through the start of the TAF
period. Cannot rule out a few periods of MVFR ceilings for the
afternoon.
For tonight into tomorrow, guidance is signaling lowering cloud
bases from just before sunrise through midday. This will
partially depend on mid-level cloud coverage allowing decent
cooling of the lower atmosphere, but have just enough confidence
to add to the later periods of the TAFs.
While isolated storms will be possible from midday through the
afternoon on Saturday during CVG's extended 30-hour TAF, will
leave out for now due to questions on coverage.
OUTLOOK...Thunderstorms possible through early next week.
