Synopsis
A warm front will slowly lift into the region today. A cold
front with a wave of low pressure passes through the region
Tuesday night. High pressure builds in for Wednesday and
Thursday, and shifts offshore Thursday night. A low pressure
system approaches from the central united states Thursday night
and impacts the region Friday and Saturday. High pressure
returns for Sunday.

Near term /until 6 pm this evening/
Issued dense fog advisory for long island until 12 noon. Vsby at
all ASOS stations was 1/4 mile or less even at 14z. Rain moving
in from the west and warm front moving onshore may improve vsby
but this remains to be seen.

Also adjusted pop based on trends of radar and in hrrr and gfs
lamp, with one band of rain moving across from late morning
into the early afternoon, followed by scattered showers this
afternoon.

Adjusted high temps upward slightly across long island and
southern ct, with a little more widespread lower 50s.

Short term /6 pm this evening through 6 pm Tuesday/
Convergence aloft in the dry layer does not seem conducive to
much rainfall tonight. As a result, only low chances for rain
were included in the forecast. If rain does develop, it may turn
out to be mainly sprinkles or light drizzle. Surprisingly big
differences exist between the NAM and GFS for Tuesday. The nam
holds off on the deep lift, and therefore the bulk of the rain,
for the entire day. The GFS brings in rain by morning. The ecmwf
supports the nam, by keeping the bulk of the rain with the main
shortwave. The GFS appears to be kicking off convection over
pennsylvania that brings residual energy in. The forecast sides
with the drier solutions, although there may be some showers or
pockets of light rain with weak vorticity advection and a moist
airmass. A blend of the models was used for temperatures.

Long term /Tuesday night through Sunday/
A southern stream shortwave over the oklahoma and kansas area
this Monday morning will weaken and track to the mid atlantic
coast Tuesday and offshore Tuesday night. Meanwhile, a northern
stream longwave trough moving through south central canada moves
east and passes into northern new england Tuesday night. There
is still some differences in whether or not the two systems will
phase, with consensus for the south stream to be more
progressive and remain separate, and farther south than other
models, while dampening and exiting the mid atlantic. The
southern movement will keep an associated warm front to the
south. This southern and separate solution has been the trend
the last several runs. With higher confidence in precipitation
affecting the area, mainly the southern half of the cwa, will
have likely probabilities Tuesday night.

A northwest flow will persist across the region as surface
high pressure builds to the north and the upper northern stream
trough moves slowly off the northeast coast through Thursday
night. The surface high weakens Thursday night as another
southern stream shortwave approaches, however the upper ridge is
holding with the axis shifting east of the area Friday. The
southern stream system will also be weakening as the wave tracks
east. Have brought in chances late Thursday night into Friday
and this may be too quick if the ridge holds. The weakening low
will re develop off the mid atlantic coast Saturday with chances
of precipitation remaining into Saturday night. Cold air will
be in place across the northern tier and some of the
precipitation may fall as snow or a rain snow mix.

Weak high pressure returns for Sunday into Monday.

Aviation /14z Monday through Friday/
A warm from approaches from the south for late this morning.

This front will lift slowly through during the late
morning/early afternoon hours, possibly washing out across or
just north of the area.

Lower ceilings, drizzle, and fog continue this morning. Expect
widespread sub-ifr at most terminals.

Ifr conditions could last through much of the period, especially
to the north and east of the nyc terminals due to the
uncertainty with the timing and final placement of the warm
front. Confidence has lowered regarding improving visibilities
and ceilings from 18z to 22z across most terminals. In any event
ceilings and visibilities will be low again for Monday night
into Tuesday morning with exact timing and magnitude in
question.
