Synopsis
Warm temperatures and patchy light rain will be interrupted by a
cold front tonight.

Near term through tonight
Minor adjustments to pops and corresponding fields were made
utilizing the latest radar imagery along with hi-res models.

Scattered rain showers should diminish through midday from
pittsburgh north. Some clearing may occur in the warm sector,
but an expansive layer of cirrus evident on satellite imagery
will only result in milky sunshine.

Today will be a warm day with temperature about 30 degrees
above the averages given the upper ohio region is firmly within
the warm sector of a deepening plains low. Shallow mixing
should not tap the warmth aloft, so records will not be
threatened despite the late january warmth.

Short term Tuesday through Wednesday night
The plains low is still projected to dig across the great lakes
by early Tuesday with Monday night cold frontal passage for the
upper ohio. Categorical pops were maintained, but system
progression, a lack of instability, and mid level dry slot
encroachment should limit rainfall amounts to a half inch or
less.

Seasonable temperature in the wake of the front is expected to
change rain showers to snow on Tuesday with upper support via
the crossing mid level trough. Progression and a relatively
warm boundary layer should limit accumulation potential before
snow shower chances taper off with building high pressure on
Wednesday.

Long term Thursday through Sunday
Building high pressure in advance of another low emerging over
the plains is likely to dry and warm conditions before rain
chances return for next weekend.

Aviation 13z Monday through Friday
Pockets of stratus and fog remain this morning, but will be
diminishing through about 15z. The warm sector will then keep
area PORTS vfr through the afternoon evening with some
clearing of the mid-level clouds. Condition deterioration can
again be expected later this evening as that lows cold front
sweeps over the area.

Outlook
Restriction potential will continue until high pressure builds
on Wednesday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
