Area forecast discussion, Aug 2, 4:05 PM EDT, 3 hours 1 minute before

Area Forecast Discussion
National Weather Service Wilmington OH
405 PM EDT Wed Aug 2 2017

.SYNOPSIS...
Daytime heating will result in scattered showers and
thunderstorms the rest of the afternoon and then again Thursday.
More storms can be expected as a cold front moves through the
area on Friday. High pressure will build in for the weekend.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Scattered storms will continue through the late afternoon and
diminish with the loss of heating early this evening. Locally
heavy rainfall and gusty winds with minor downbursts will
remain possible. Beyond early evening, expect little to no
activity with partly cloudy skies. Lows will be a bit warmer
than last night.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
Weak troughing will persist across the region with minor
disturbances moving through it. This will result in additional
scattered showers and thunderstorms, primarily in the afternoon.
However, there is the possibility of some activity lingering
into the night in the northwest counties. Weak wind fields will
result in unorganized storms with locally heavy rainfall and
gusty winds the primary concern. Highs should be close to
persistence. Lows will be in the mid to upper 60s.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
A fairly strong mid level short wave embedded in a broader upper
level trough will pivot east across the southern Great Lakes Friday
into Friday night. This will help drive an associated cold front
east across the upper Ohio Valley through the day on Friday. The
last couple of model runs have trended somewhat slower with the
frontal passage and as as a result, our area will be in a somewhat
more favorable position for thunderstorm development. As we
destabilize ahead of the front through late morning and into the
early afternoon, expect to see an increase in coverage along and
ahead of the front across our area. Precipitation should then taper
off fairly quickly from west to east through the mid to late
afternoon hours as the front moves east. Mid and deep layer shear
will be on the increase along and ahead of the front as wind fields
increase ahead of the short wave. This will combine with the slower
timing of the front to increase our severe threat, particularly
across our eastern areas where the better instabilities should
exist through mid afternoon.

High pressure and a cooler, drier airmass will build in behind the
front for the weekend. Highs on Saturday and Sunday will mainly be
in the mid to upper 70s with morning lows in the mid to upper 50s.
The 12Z GFS has trended faster with the approach of the next trough
axis early next week but it is still slower than the past several
runs of the ECMWF. As a result, will speed up pcpn chances heading
into Sunday night and then linger a chance through the day on
Monday. With the faster timing, will also go ahead and dry us out
Tuesday into Wednesday. High temperatures will remain in the mid to
upper 70s through mid week.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
Scattered convection will occur during the early part of the TAF
period. Difficult to time when these might affect any of the
terminals, so maintained VCTS but tried to limited it to the
hours when coverage would be greatest and therefore having the
better chance of impacting the TAF sites.

Some cumulus may linger through the night, although many places
will clear. There will be an increase in cumulus towards 12Z and
beyond. Scattered showers and thunderstorms will redevelop, but
that far out in time have opted not to include mention of
precipitation in the TAFs.

OUTLOOK...Thunderstorms are possible Thursday afternoon through
Friday.
