Synopsis
A frontal system will approach today, and pass early Wednesday.

High pressure will build in for Thursday, and drift offshore
Thursday night. A low pressure system will impact the region
Thursday night into Saturday. High pressure builds in Sunday and
Monday.

Near term /through tonight/
Satellite indicates the main upper level system was moving
over eastern kentucky into west virginia. Elevated instability
was increasing across the forecast area evidenced by showers and
thunderstorms. These should continue to develop per the nam
which appears to have a very good handle on the activity thus
far. Fog was widespread, however, visibilities were generally 2
to 4 miles, with areas 1 to 2 miles. As the main system
approaches this afternoon and evening, more showers can be
expected. Some embedded thunderstorms cannot be ruled out until
the instability axis exits, leaving remnant stratiform light
rain. The models were in good agreement so a blend was used for
temperatures through tonight.

Short term /Wednesday/
Dry weather with a northwesterly breeze. Despite a cooler
airmass in place, temperatures will actually be warmer than
Tuesday because of deep mixing. Mostly sunny skies are progged,
although some fair weather convective clouds will be possible if
they are able to overcome the subsidence. A blend of the
guidance was used for temperatures.

Long term /Wednesday night through Monday/
The extended period will feature a split flow across the continental
united states with systems moving through active northern and
southern streams. As a result, even through there are similarities
in the longwave and overall solutions, the details of the forecast
have become more uncertain, and inconsistencies from run to run have
increased. Currently there is now little to no phasing of systems
impacting the east, and in particular the region, Thursday night
into Saturday, and yet another system Monday night into Tuesday.

There are now more uncertainties as to the depth of the lows,
timing, and tracks.

For late Thursday night through Saturday night have long period of
probabilities, and even likely probabilities from Friday into
Saturday. This is likely too long a period however, with the
uncertainties wanted to maintain some consistency with prior
forecasts. Both the ECMWF and GFS have some lingering cold air
across the northern portions of the CWA Thursday night before warm
advection increases. So have kept a mix of snow and rain inland.

Canadian high pressure builds in for late Saturday night into
Monday, and possibly Tuesday if ridging remains as per the gfs.

The ECMWF is quicker to weaken and shift the ridge off shore
Tuesday. Have introduced a low chance of precipitation for
Tuesday.

Aviation /14z Tuesday through Saturday/
A front remains just south of the terminals and attempts to
push back north as a warm front today.

Light ene winds this morning with areas of rain and low
ceilings. Lifr conditions at times this morning, otherwise areas
of rain this morning will result in ifr conditions at times,
and then back down to lifr when the rain lightens or stops.

Some thunder will be possible along the southern terminals
(kewr, kjfk, kisp) this morning between 14z-16z
another area of rainfall will arrive later in the day and for
the evening. There is a thunderstorm chance with this next area
of rainfall for the city terminals, but not confident enough to
put in tafs at this time. Ifr to lifr conditions are expected
to prevail until about 6z late tonight, with improving
conditions thereafter from west to east.

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.
