Area Forecast Discussion
National Weather Service Wilmington OH
204 AM EDT Sun Sep 9 2018
.SYNOPSIS...
The remnants of Gordon will ride across the region tonight into
Sunday, producing periods of heavy rain. A drier and warmer
weather pattern will develop towards the middle of next week.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Showers continue across the area with some enhanced reflectivity
and rainfall occurring in the Tri-State. It looks like the
southerly branch of the low level jet pushing into the region
will increase in strength which will enhance convergence and
result in regeneration of echoes across the region even though
recent radar depictions suggest a back edge to the
precipitation. This should result in locally moderate to heavy
rainfall.
Expect little change in temperatures through the rest of the
night.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/...
By 12Z Sunday, the sfc low will be southwest of the fa, with a
band heavy rain forecast to be pushing through the region. As
the sfc low moves east, so will the heavy rain. As mentioned
above, and band of heavy rain could train over the se counties
on Sunday. Lowered highs in the northwest to mid 60s.
Temperatures will warm into upper 70s in the far southeast
counties.
A chance of light pcpn will linger in the west early Sunday
night, then drying will start to filter in from the west.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Most of the precipitation from the remnants of Gordon will be
exiting the area by the start of the long term. A weak upper level
disturbance will keep clouds and a few showers in the forecast for
Monday. This will also keep temperatures down with high
temperatures only expected to reach into the 60s and 70s.
Dry conditions will move into the region Monday night and continue
through Wednesday. Went close to guidance for temperatures during
this time. A few storms will be possible primarily during the
daytime hours Thursday and Friday.
There is a little more uncertainty heading into Saturday depending
on the remnants of the next tropical system. Limited precipitation
chances on Saturday to a chance to account for this uncertainty.
Also decreased temperatures slightly with chance for rain and
potential cloud cover.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
MVFR to IFR conditions across the area early this morning with
widespread rain continuing. There appears to be a back edge to
the pcpn pushing up from the southwest. However, the 00z models
and many of the latest higher res models are suggesting pcpn
will fill back in through the morning hours as a secondary wave
lifts up from the southwest. As a result, will continue with
widespread pcpn and primarily IFR cigs through much of the day.
Pcpn chanced should begin to taper off from the west later this
afternoon and into tonight but expect mainly IFR cigs to persist
through the remainder of the TAF period.
OUTLOOK...IFR ceilings will likely continue into Monday.
