Synopsis
High pressure is moving in. Snow showers will taper off and
lift northward this morning. Fair and mild weather is in store
for Tuesday. A mainly-dry cold front will move in Tuesday night,
and cool temps off to near seasonal levels for the rest of the
week.

Near term until 6 pm this evening
Radar getting very quiet, and only very light snow left. All is
well with the forecast. Minimal changes to near term temps.

Prev...

wind backing to the SW as the high pressure moves in from the
sw. The earlier band which Sat for so long over clearfield and
centre counties is dead and gone. Not much in the way of radar
returns now as the subsidence inversion lowers. Sunshine should
increase this morning in the SW and the E should go to full
sunshine. Latest cams are very consistent in lifting any
remaining snow to the north of the CWA before noon. Not enough
snow left to fall to justify keeping the advy. So we will drop
it now.

Short term 6 pm this evening through 6 pm Tuesday
Clear skies and light wind in the east will allow temps to drop
into the 20s while the SW breeze keeps the higher elevs in the
sw in the lower 30s.

Tuesday looks very nice fair mild. We'll be under the thermal
ridge Tuesday and will get into the u40s to l50s. As the sun
sets, as small chance of a shower exists in the far nw.

Long term Tuesday night through Sunday
A weakening front will slide by to our north and bring sct
shrasn to the NW half of the area Tuesday night and very early
Wednesday.

Another area of high pressure will build east and keep us mainly
dry at least through the end of the week, before a new frontal
system takes aim at the area.

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.
