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

Near term through today
Further adjustment to pops were needed this morning as a
shortwave in southwest flow aloft is supporting showers along a
northward surging warm front. Precip. Probabilities, albeit
for light showers, will shift north of I 80 after daybreak in
accordance with warm front positioning.'
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. Low cloudiness and
rain chances should thus be alleviated after passage of the
morning disturbance, but shallow mixing should not tap the
warmth aloft, so records will not be threatened despite the late
january warmth.

Short term tonight through Wednesday night
Tthe 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 07z Monday through Friday
MVFR stratus, with ifr north, and areas of fog and light showers
will maintain degraded conditions early this morning; however,
improvement toVFR is anticipated from the south after daybreak
as the warm sector of a plains low pressure is enhanced with
passage of the morning, shower-supporting shortwave. Condition
deterioration can again be expected 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.
