Synopsis
A mix of rain and snow is expected today with the passage of a
cold front. Dry but cold conditions on Wednesday with building
high pressure.

Near term through today
Only minor changes to the overnight period. Pops have been
updated with the latest hires model guidance and ongoing radar
trends. Area of precipitation that is over the region will
continue to drift eastward overnight as a shortwave trough
swings through. The bulk of the large scale ascension will
remain to the south and east of pit, so would expect the
precipitation to the north and west to end overnight. The push
of cold air will be hung up by this upper level energy, so the
initiation of cold air advection should hold off until after
dawn and after the bulk of the precipitation has exited.

The surface low will rapidly head toward the NE coast today.

Strong cold advection is expected, though the period for
efficient snow fall is rather short, as dry air advects
overhead and moisture below the inversion cannot tap into the
dendritic growth zone. That, and given forecast wind direction
aloft, would think the focus for snow showers initially would be
over the i-80 corridor with the development of lake bands during
the afternoon. Better conditions for upslope snow showers over
the ridges would hold off until later in the day. But these
conditions are meager as well owing to the previously mentioned
atmospheric setup.

Short term tonight through Thursday
Strong subsidence will limit any further snow production and
accumulation tonight. Have minimal amounts in the north and
ridge zones through Wednesday morning.

High pressure will build overhead Wednesday with cloud cover
diminishing. That being said, temperatures both Tuesday and
Wednesday will remain 10-15 degrees below seasonal normals.

Long term Thursday night through Monday
Next low pressure system is still progged to approach Thursday
although there remain some timing issues given strength of the
upper low. Maintained likely pops but adjusted timing a bit
slower given latest ECMWF and NAM guidance. That being said,
there still remains some concern for freezing rain mixed precip
at onset on Thursday, though this may be less of a concern if
the models continue to slow the system down. Have opted to add
the freezing rain mention, though confidence is still low given
timing concerns.

After this systems departure, the broad upper will be reinforced
maintaining the chance for showers and below average
temperatures through the weekend.

Aviation 06z Tuesday through Saturday
MVFR ifr conditions are expanding across the region through top
down moistening. Sfc temps remain above freezing and should
portend to precip falling as rain, with the exception across
ridge tops and around kduj. A brief clearing of low CIGS is
expected later this morning in between the exiting low pressure
system and the incoming colder air aloft. NW flow will keep
chances for MVFR conditions overnight.

Outlook...

briefVFR conditions Wednesday before widespread restrictions
and potentially mixed precipitation will return Thursday with
the next storm system.

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.
