Synopsis
A stationary front front will remain to the south today. Low
pressure will pass to the south tonight. High pressure will
build in on Wednesday and Thursday, then pass east Thursday
night. Low pressure approaching from the central states will
impact the region Thursday night into Saturday. High pressure
will build in on Sunday and Monday.

Near term /through tonight/
Adjusted coverage of showers/tstms based on ongoing and upstream
activity, which was fairly well represented in high-res
guidance. Elevated instability is best correlated with 12z nam
tt indices and indicates that a second round of showers/tstms
after the first moving across long island, over southern nj and
se pa, and located NE of the sfc low centered between washington
dc and baltimore, should hold together and move into nyc metro
and long island from late afternoon into the early evening as
the low moves ene toward or just south of the area,
fog limited ATTM mainly to the higher elevations and also in
the valleys well NW of nyc per sfc obs.

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 /18z Tuesday through Sunday/
A couple of fronts remains near the region through this
evening. A cold front pushes across the region overnight. High
pressure then builds into the region on Wednesday.

Ifr or less continues through at least 06z in low stratus, fog
and periods of rain. Winds will generally be less than 10kt from
the east-northeast.

After 06z, a cold front will push across the region, with winds
becoming northerly, then northwesterly and increasing to
10-15kt by 12z Wednesday. At this time, conditions will
gradually improve toVFR with mostly clear skies for Wednesday.
