.SYNOPSIS...
High pressure will build across the region today through Saturday
offering drier and cooler conditions. On the backside of the high a
southerly flow will develop Sunday with temperatures warming close
to normal. A chance of showers and thunderstorms returns Monday with
the approach and passage of a frontal system.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
With the upper level trough overhead and low level northeast flow,
clouds will hang tough across much of the area into this afternoon.
However, they should begin to slowly erode from the west later in
the day as surface high pressure begins to build into the region.
Temperatures will be cool today with afternoon readings in the mid
40s to lower 50s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
A large full latitude mid level trof to translate east of the area
tonight with a northerly flow developing across the area. Clouds will
scatter out late in the day into the early evening. An embedded
shortwave rotating around the low to the east will allow the
potential for clouds to spill back into central Ohio late tonight. An
axis of surface high pressure will build into the area from the west
overnight into Saturday. Expect cool temperatures with areas of
frost and freezing temperatures in many locations. Reading to drop to
lows from the upper 20s to the mid 30s.

Expect to observe sunshine in the dry airmass with the surface high
overhead Saturday. High temperatures look to range from the lower to
the middle 50s.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Surface high pressure moves east as upper level ridging builds to
the northwest overnight Saturday. Return southerly flow will see
lows in the mid 30s, possibly near freezing in parts of the Hocking
Hills. On Sunday, axis of the upper ridge is overtop of the region
and will help highs reach the lower 60s. South flow turns southwest
and increases overnight, enough so that low temperatures only drop
to a few degrees on either side of 50, warmest in the west.

On Monday, s/w energy on zonal westerly flow will interact with the
warmer and more moist airmass to produce some patchy light rain
showers early in the day, then increase the chances as a cold front
shears out over northern CWA with best chances found along/n of I-70
corridor. Temps ahead of the front will warm nicely into the mid 60s
northwest to lower 70s s/se. Showers will end overnight and lows
will drop into the 40s.

Axis of the upper low and vorticity maxima cross the region Thurs
afternoon and could produce some light cold pool showers. Attm, only
very low pops are included which will not result in any mention of
precip on this day. Temps will be notably cooler and range from near
50 along/n of the I-70 corridor, mid 50s elsewhere. Overnight lows
will also drop once again to the mid 30s.

A high pressure ridge will allow sun to fight against the cold
advection, with meager results of highs in the upper 50s Wed.
Similar to Sat night, high pressure moves east with return flow
overnight keeping the CWA in the upper 30s, warmest in the sw.

Thursday will see low pressure in the Midwest move into Michigan`s
L.P.. A cold front will drape across the Ohio Valley but timing is
going to make a large difference in both rain chances and highs on
this day. It looks like NBM is splitting the difference on highs
with a uniform 63-65 across the CWA and low chance pops, maximized
in the northwest and then increasing overnight. Overnight lows in
the mid 40s will then warm to the lower 60s on Friday, where there
will be a low chance of some light cold pool showers once again.

&&

.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
Low level cyclonic flow and CAA was resulting in a solid deck of low
clouds working south across the TAF sites. Expect MVFR CIGs with
some IFR CIGs to continue to expand southward this morning. Best
chance for a period of IFR CIGs is at KDAY and KILN. MVFR CIGs
expected to linger through most of the daytime hours for our eastern
terminals, but VFR improvements expected in the west by early
afternoon and last at KCMH/KLCK during the early evening.

Sustained winds of 10-15 kts expected through majority of the day
shifting from the northwest to north-northeast. Some gusts around 20
kts are expected this aftn. North to northwest winds to drop off to
less than 10 kts tonight.

OUTLOOK...No significant weather expected.
