AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1141 AM EST Wed Feb 20 2019
.SYNOPSIS...
As low pressure and cold front will move east across the Great
Lakes and the Ohio Valley today into tonight. High pressure
will move into the Ohio Valley on Thursday and Friday, bringing
dry conditions. The next chance for rain will occur over the
weekend, as another area of low pressure moves into the Great
Lakes.
&&
.NEAR TERM /UNTIL 11 PM THIS EVENING/...
Rain has exited southeast of the CWA this morning. Some drizzle
is found behind it and will continue until showers develop this
afternoon. A lull is expected until some heating and a mid
level shortwave combine this afternoon to produce showers and
possibly a thunderstorm or two. These storms that do develop may
train over a particular area and have the potential to produce
an isolated additional inch of rain, keeping the flooding threat
through nightfall.
Do not believe that storms will linger past the late day over
ILN CWA and the flooding threat ends with the coming night as
any lingering rain/drizzle on the back side of the system will
be light without any threatening impacts.
Best chance of thunder this afternoon appears to occur where the
flood watch is out, though the forecast update was a little
more generous to the west and north of this area.
&&
.SHORT TERM /11 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Behind the front this evening, rain should gradually come to an
end, though some patchy drizzle or light rain could continue
for a few hours after the front has passed. Surface high
pressure is expected to build through the middle Mississippi
Valley region and into the Ohio Valley by Thursday, resulting in
a much quieter weather day.
Temperatures were
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
High pressure will remain across the region Thursday night.
Under filtered mid and high clouds, lows will drop into the mid
20s north to the lower 30s south.
For the period Friday into Friday night, as the surface high
moves east, a mid level ridge axis extending from a strong
subtropical mid level ridge off the Florida coast will begin to
reestablish itself. In additional, embedded waves of energy will
begin to move northeast around the periphery of this high into
the Ohio Valley. This will begin a period of increasing clouds
along with an increasing threat for rain from south to north as
moisture becomes transported northward. Highs on Friday will
range from the lower 40s north to the upper 40s south. Lows
Friday night will range from the lower 30s north to the lower
40s south.
The weather pattern becomes active once again as we head into
the upcoming weekend. A dynamic mid level trough is forecast to
pull out of the southwest U.S., into the central Plains, then
northeast into the Great Lakes. As this occurs, a significant
amount of moisture will be transported northward back into the
Ohio Valley once again. In fact, some models suggest pwats
approaching 1.50 inches which is record pwat territory for the
month of February (since upper air flights have been recorded at
Dayton and Wilmington). On Saturday, rain will overspread the
entire region as low level moisture transport accompanies a
northward moving warm front. By Saturday night into Sunday, low
pressure will deepen as it heads to the Great Lakes from the
central Plains. As this occurs, an attendant cold front will
sweep east through our region. Models are indicating some
instability with the front, along with a strong 60-70 knot low
level jet. SHERB3 parameter is indicating values around 1.0 as
well. Thus, have continued with categorical PoPs with showers
and a slight chance of thunderstorms. We will have to monitor
this pattern in the coming days as this could end up being a
high shear/low CAPE issue with potential damaging winds and
isolated "spin up" tornadoes. Too early to mention in the HWO at
this moment, be we will continue to monitor for updates. In
addition, locally heavy rain may bring at least another 1 to 2
inches to the region, which will already still be trying to
recover from Wednesday's system. As the front pushes through,
pcpn will diminish in coverage. Deep low pressure over Michigan
and strong winds aloft will result in windy conditions on
Sunday. This looks like at least a wind advisory at this point
as the 00Z EPS indicating 60-70 percent chances for wind gusts
over 40 knots. It could end up being a high wind warning in
spots if momentum transfer values come to fruition (lower 50
knots for west central Ohio). Have increased sustained winds and
wind gusts in the HWO to at least get the ball rolling in the
right direction. Will continue to mention the potential for
strong winds in the HWO. Highs on Saturday will occur late in
the day or in the evening, 50s to lower 60s. CAA by Sunday will
cause temperatures to slowly fall, reaching the mid 30s
northwest and the mid 40s southeast by Sunday evening.
Quieter weather is forecast to return by Monday as high
pressure builds into the Great Lakes and Ohio Valley. It will be
cooler with highs in the upper 30s north to the mid 40s south.
The next weather system to affect the region is poised for
Tuesday with at least a chance of rain. Highs will range from
the lower 40s north to the lower 50s south.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
LIFR cigs in some drizzle and MVFR mist will continue until
showers and possibly a thunderstorm develop this afternoon with
an upper level shortwave passing by. Expect low cigs to persist
overnight with MVFR vsbys. This afternoon will see the passage
of a low level jet as the upper s/w crosses, and llws of 40-45kt
is expected around 2kft.
Bulk of convective showers will exit the forecast area by late
afternoon, and lingering light rain and drizzle will remain
possible through about midnight with improving conditions
overnight and moreso during the day Thursday.
OUTLOOK...Continuing MVFR/IFR conditions are expected through
early Thursday morning. MVFR conditions are possible again on
Saturday and Sunday, with gusty winds expected on Sunday.
