Synopsis
Snow should end tonight as a cold front exits. High pressure
should maintain dry and cold weather for the rest of the work
week.

Near term until 6 am this morning
Quick update early this morning to pops and hourly
temperatures... But overall the ongoing forecast is on track.

Based of latest observations and hi-res progs... Further snow
accumulation for the ridges looks minimal so have cancelled
remaining advisories. Previous discussion follows..

Snow should continue to taper off from w-e as a cold front
exits, upper divergence shifts e, and surface ridging begins to
build in. Some additional snow showers could persist in the
higher terrain overnight. A lowering temperature inversion and
decreasing moisture should end this by morning. Maintained
current advisories as is for now with the snow ongoing.

Otherwise, patchy stratocu with upper troughing and cold
advection should affect the area tonight. Lows should be around
zero.

Short term 6 am this morning through Friday night
Mainly dry and cold weather is expected Wed under as the
surface ridge builds under the upper trough. A warming trend
will commence on Thu as an upper ridge builds across the
region.

Long term Saturday through Tuesday
Warm advection will predominate through the weekend as sly
low-level flow strengthens ahead of an upper-level wave in the
swrn conus.

Some light precipitation is possible over the weekend as
temperature climbs into the 40s and 50s. Warm air will linger
until a frontal passage on mon.

The best chance of rain will come on Mon along and ahead of the
advancing cold front. Model timing differences continue as they
resolve the future storm system with varying strength, but the
trend today has been toward a slightly-slower frontal passage.

Pop timing was accordingly shifted later by a few hours.

Aviation 05z Wednesday through Sunday
Ifr E of I 79 should improve briefly toVFR as snow ends with
an exiting cold front and building surface ridging. MVFR
stratocu in cold advection and upper troughing should move back
in later tonight, and continue through Wed until mixing lifts
cigs heights back toVFR levels.

Outlook
Restriction potential returns over the weekend with approaching
low pressure.

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.
