Area Forecast Discussion
National Weather Service Wilmington OH
152 PM EDT Sun Sep 9 2018
.SYNOPSIS...
The remnants of Gordon will continue to push east across the
region today and tonight. A drier airmass will then move into
the area, leading to a gradual warming trend through mid week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Radar is showing a band of heavy showers and thunderstorms in
eastern KY, lifting northeast. This band will affect the
southeast corner of the fa for the next few hours.
Farther to the north, light rain is falling, with drier air now
working into wrn Indiana. The models are trying to redevelop
heavier pcpn over the middle of fa today. Not confident in this
solution. Think that light pcpn may linger, but that the best
chance of the heavier rains will be in the far se, where
convection chance are the highest. Will be trimming back the
FAA to the eastern and srn sections.
Backed temperatures down to the upper 50s in the nw to the lower
70s in the far southeast.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
The surface low will pivot slowly northeast to over Lake Erie
through late tonight. As it does, the better forcing will shift
east of our area with a dry slot working in from the southwest.
This should allow for pcpn to taper off west to east across our
area tonight with mainly dry conditions expected on Monday.
Highs on Monday will remain on the cooler side, ranging from
the upper 60s in the north to the lower 70s in the south.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Surface high pressure will be building into the region to start
the long term period, ushering in a stretch of warmer and
relatively drier weather for the Ohio Valley that is likely to
evolve midweek through the end of the workweek. In fact, an
elongated area of high pressure will likely remain nearly
stationary from the western Ohio Valley northeastward to the
interior northeast Tuesday through Thursday. This being said,
just south/east of the high center across southeastern portions
of the Ohio Valley, embedded weak mid/upper level disturbances
will likely track northeast through the mid-layer steering flow.
This could be enough to initiate some very isolated diurnally-
driven shower/storm activity both Wednesday afternoon and
Thursday afternoon in the far south/east part of the ILN FA.
However, confidence on this isolated activity developing remains
low this far out.
Slightly below normal temperatures Monday night through Wednesday
will gradually trend closer to seasonal norms toward the end of the
workweek. Highs will generally be in the upper 70s Tuesday and
Wednesday and the low/mid 80s for the final several days of the long
term period.
By Friday and Saturday, the weather pattern becomes much more murky
for the local area as Florence /or the remnant center of Florence/
tries to impinge on the weak ridging that will be in place across
the Tennessee and Ohio Valleys. There remains considerable model
disagreement in the exact track and timing of Florence /and her
remnants/ but initial thoughts are that the center should remain
well south/east of the local area. As such, will maintain the mainly
dry fcst both Friday and Saturday with only a very small chance for
diurnally-driven shower/storm activity in the south/east.
&&
.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
The tafs remain north of the sfc low, on the cold side of the
boundary. IFR/MVFR stratus with areas of light rain continue to
lift northeast across the tafs.
The surface low near KLEX is forecast to lift NNE into
south central OH, then just to the east of KCMH/KLCK. Tafs are
therefore forecast to remain in the cool sector, with the low
stratus continuing to dominate the weather. The rains are
forecast to end from west to east this evening, but then MVFR,
the IFR fog is expected to form overnight.
After 12Z Monday, the fog should gradually lift, but ceilings
will linger in IFR, before slowly lifting during the late
morning into the early afternoon.
OUTLOOK...MVFR ceilings will be possible into Monday afternoon.
