Synopsis
Unseasonably warm conditions are expected until the passage of a
cold front tonight.

Near term until 6 am Tuesday morning
710pm update... Line of showers moving eastward a bit faster then
previous update. Have sped up the showers this evening and also
increased pops to categorical.

Previous discussion...

line of showers associated with a wave out ahead of the cold
front will slowly make progress toward the region. Most, if not
all, of the model guidance has slowed the onset of precipitation
significantly - resulting in a complete reconstruction of pops
and timing. This has been done based on the hrrr, with the front
not expected to make full passage across the upper ohio valley
until Tuesday morning. Until this time, strong warm advection
will continue, with a non diurnal trend forecast. Some cooling
qpf amounts still look reasonable, with the combination of
recent snow melt and rainfall tonight not likely to pose many
hydrologic issues outside of where some ice jam movement is
possible.

Short term 6 am Tuesday morning through Thursday
Low over missouri will lift northeastward toward the great lakes
through Tuesday. Expect high temperatures Tuesday to be realized
early as cold advection brings values down through the
afternoon. Some insolation may slow this downturn in temps, but
generally anticipate cooling values with an eventual changeover
to snow. Model profiles do not maintain saturation deep enough
into the snow growth zone for very long, outside of any upslope
later Tuesday evening night, so any snow accumulation will be
light or negligible with the warmth of the last couple of days.

Northwesterly flow will maintain snow chances, again with the
likelihood best in the terrain, through Wednesday before high
pressure builds overhead for the remainder of the period.

Expect seasonable temperatures for Wednesday and Thursday.

Long term Thursday night through Monday
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 00z Tuesday through Saturday
Prefrontal rain showers will remainVFR for the most part this
evening, although low level wind shear will be a concern for the
night as low level flow increases above a surface inversion.

There may be a brief break in precipitation overnight ahead of
the main frontal precip band, which should bring MVFR
conditions. Still can't rule out a rumble of thunder, but
chances remain too low for inclusion. Behind the front, mixing
should bring ceilings back up toVFR for a time, as well as
west-southwest gusts reaching the 25 to 30 knot range by
midday. Ceilings may then float back down to borderline MVFR
levels during the afternoon, with lingering rain showers mixing
to snow north of pittsburgh by sunset.

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

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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.
