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 6 pm this evening
Widespread wintry pcpn has come to an end. Therefore, have
cancelled the remainder winter weather advisories. However, the
after effects will continue for the remainder of the morning
hours until temperatures sufficiently warm into the mid and
upper 30s in these locations. Thus, have issue an sps to account
for this.

Previous discussion--->
later this afternoon, a surface low is expected to move
northeast into the great lakes, and a front extending southward
from the low (or from an occlusion) will cross through the iln
cwa this evening. Ahead of the front, another surge of moisture
is expected, resulting in another round of widespread
precipitation. Behind the front, winds should quickly shift to
the southwest or west, and some 20-30 mph gusts are expected.

No real change to forecast thinking for the flood watch,
although the heaviest pcpn did fall to the northwest of this
region early this morning.

The temperature forecast today is problematic, as expected,
thanks to two factors -- the expected development of a
temperature gradient across the cwa, and the failure for
temperatures to begin to respond to warm advection so far early
this morning. Temperatures have been limited to a range from the
upper 30s to upper 40s.

Short term 6 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.

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 14z Wednesday through Sunday
A mix of precipitation types is continuing at the TAF sites as
of this writing, but the transition to rain has begun. Kcvg kluk
are all rain, and kday kiln should be all rain within another
hour or two. A mix of precipitation types will continue at
kcmh klck through around 14z. In addition to these concerns, ifr
conditions will remain widespread for quite a while, though some
breaks to MVFR are possible as precipitation becomes lighter
later this morning. East to southeast winds today may
occasionally gust to around 20 knots.

Tonight, rain will continue, though gradually decreasing in
intensity (and changing to drizzle) after 00z. There will also
be a period of llws, and later, some gusty winds (20-25 knots)
after a front moves through the area, shifting winds to the
southwest and eventually to the west.

Outlook... Continuing MVFR ifr conditions are expected through
Thursday morning. MVFR conditions are possible again on
Saturday and Sunday, with gusty winds expected on Sunday.
