Synopsis
Light snow possible today mainly north of pittsburgh and along the
ridges before high pressure returns on Saturday. A weak cold front
will cross the region Sunday. Below normal temperatures will
continue into next week.

Near term until 6 pm this evening
Precipitation has flared back up this morning ahead of a
shortwave approaching from the west. Precipitation remains
mainly snow, but with a decrease in upper level moisture, some
patchy drizzle freezing drizzle is mixing in. Have increased
pops to include likely coverage for an hour or two, and have
added a mention of patchy freezing drizzle as well. With many
temperatures hanging right around freezing, do not expect
significant impact from freezing precipitation at this point,
but will continue to monitor closely.

Previous for this afternoon...

the only real concern for today is the possibility of freezing
drizzle in the ridges with orographic lift and relatively warm
cloud top temperatures indicating the likely absence of any
cloud ice. A crossing shortwave this afternoon should result in
some scattered light snow, however, no significant accumulation
is expected. There is some concern for possible freezing
precipitation with this feature along and north of i-80 where
surface temperatures should be close to freezing and forecast
soundings show a lack of cloud ice... But current IR imagery does
currently show cooler cloud tops with this feature so opted to
not include in the hwo at this time. Cold air advection and
cloud coverage will limit the diurnal temperature range today
with forecast highs remaining in the 30s. Winds will be gusty
today with a tight pressure gradient.

Short term 6 pm this evening through Sunday
Saturday will be dry but temperatures will remain below normal
with sfc high pressure in control. A weak cold front will return
rain and snow to the region later on Sunday... With accumulations
largely limited to north of pittsburgh.

Long term Sunday night through Thursday
A crossing wave will bring precipitation back to the region
Tuesday afternoon and overnight... But otherwise... The extended
looks to be largely dry with ridging the dominant feature
through the second half of the week.

Aviation 12z Friday through Tuesday
Restrictions will continue in the wake of the low pressure
system lifting northeast today with some additional scattered
snow showers possible later today with a crossing wave.

Outlook...

small improvements in restrictions are expected through the
weekend as drying commences with NW flow. A disturbance Sunday
will bring more restrictions with more precipitation.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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.
