Synopsis
High pressure will slide to the east tonight followed by rain
developing this morning ahead of approaching low pressure and a
cold front. Snow showers are likely on Sunday.

Near term until 6 am this morning
Minor updates early this morning based off latest trends but
overall the inherited forecast remains on track. Previous
discussion follows..

The eve update featured adjustments to hourly temperature trends
as radiation has supported a more rapid drop than expected. That
trend will be reversed as warm advection, and associated high
and mid level clouds will spread over the region tonight with
the approach of a shortwave in developing wsw flow aloft. That
system will bring the first round of rain to the area during the
predawn hours. Little change in the pop forecast was needed as
per the latest hi res model guidance and forecast trends.

Short term 6 am this morning through Monday
Periods of rain will continue on Saturday as the trough
amplifies over the ohio valley and shortwaves ride along in
southwest flow. Pops will be highest where the warm front
resides, before it shifts north of the entire region. There may
be a lull in the precip ahead of the actual cold front, but for
now, did not get that specific with timing. While a very strong
low level jet will be present with wind 50+ kts, a capping
inversion looks to keep much of this from translating to the
ground, at least until the cold frontal passage Saturday
evening. Once the front passes, the strongest winds aloft will
shift east, however steepening lapse rates in cold advection may
allow for gusts to 40kts, with higher gusts possible in the
terrain. Still, it looks likely the best chance for headline-
criteria gusts may be in the terrain Saturday night. Will
maintain the mention in the hwo for now.

Upper trough will pivot across the region on Sunday with cold
northwest flow resuming and snow showers expected. Have strayed
little from the previous forecast, which holds the highest pops
in the snow belt north of i-80 and in the mountains of pa WV md
where lake enhancement upslope is anticipated. Still thinking
2-3 is reasonable, though some higher amounts may be possible.

Depth of saturation will quickly fall below the prime snow
growth zone in building subsidence in the terrain, which should
keep rates down.

Snow showers will continue through Sunday night as another
reinforcing shortwave digs across the region. Conditions should
begin to improve on Monday, as a surface high builds eastward
and winds back toward the west.

Long term Monday night through Friday
Weak ridging will continue until the passage of a weak front
midweek. The deterministic guidance is rather unimpressive with
the front and much of the lift will be situated well to the
north, where the low is expected to pass. Broad troughing than
remains in place through the end of the week. Other than some
cool temperatures, will keep pops low based on the model blend.

Aviation 07z Saturday through Wednesday
Vfr conditions are expected until rain overspreads the area this
morning with an approaching warm front. Deterioration to MVFR is
expected, with eventual ifr for PORTS N of I 80. Low level wind
shear is expected early this morning resulting from low
inversion levels and a developing low level jet. Some
improvement back toVFR is possible for PORTS from pit S until
the approach and passage of a cold front this evening returns
MVFR to the area.

S-sw wind gusts to 25 kt will also plague all terminals by this
aftn, with W gusts around 30kt after FROPA this evening.

Outlook
Restrictions are likely with Sun upper troughing and cold nw
flow.

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.
