Synopsis
A warm front stalls across the area today, before shifting
northward tonight into Tuesday morning. A cold front quickly
follows for Tuesday evening. High pressure builds during the
mid and late week period. The high moves east next weekend ahead
of a cold front that likely passes sometime Sunday.

Near term until 6 pm this evening
Made some minor changes to temperature and pops with this forecast
update to reflect current conditions.

Otherwise, above normal temperatures will continue in subtle
warm advection, though the day. Highs will depend on the
northward progression of the warm front. Cold air damming to
the north of the front, primarily across the lower hudson valley
and connecticut in combination with the overcast skies and
light drizzle will likely keep temperatures a few degrees below
guidance. Farther south across northeastern nj, the nyc metro
and long island, there is some potential for temperatures to be
higher than guidance forecast if the warm front progresses
northward faster.

Short term 6 pm this evening through 6 pm Tuesday
Well above normal temperatures are expected for tonight as
overcast skies and warm advection prevail. A non-diurnal trend
will occur as the warm front begins to shift northward through
the area. Similar to the uncertainties of Monday, low
temperatures will largely depend on the speed in which the warm
front passes to the north, while highs will be around 10-15
degrees above climatological normals as the front moves
through.

After the passage of the front, low-level mass response to the
potent upper short wave will allow for quick moisture advection,
with southwest flow just above the surface ranging from 50-70
kt. Deep layer moisture represented by precipitable water
values around 1-1.20 inches will be potentially close to a
climatological maximum for this time of year, setting the stage
for periods of moderate to locally rainfall. With strong warm
advection in the low- levels and cooling temperatures aloft with
the approaching upper short wave, there will be a period of at
least marginal elevated instability, which will support
thunderstorms and locally heavy rainfall. Should temperatures
rise enough at the surface to lead to a weakened inversion,
there is potential for the stronger winds above the surface to
mix down in any thunderstorms. Regardless, a tight pressure
gradient will lead to strong winds across the area through the
day.

With deep-layer flow strongly veered initially, expect heavy
showers to be scattered in nature. As the front approaches, low-
level flow will veer, creating a more unidirectional deep-
layer profile oriented along the boundary that may support the
development of a line of showers and thunderstorms. Thereafter,
precipitation will rapidly decrease from west to east following
the frontal passage.

Long term Tuesday night through Monday
The main question among available guidance is speed of downstream
trough as is passes across the country. The GFS not surprisingly
remains on the faster side of the guidance. ECMWF is trending
quicker, while ensemble guidance suggests a slightly slower
progression east.

This obviously impacts surface features and associated cold front as
well.

Overall, dry weather prevails Tuesday night through early Saturday,
and quite possibly through Saturday night. Any lingering rain with
the cold front Tuesday evening quickly ends. Upper shortwave passes
across the northeast, and is followed by another weak upper level
shortwave Wednesday night, with little fanfare with this second
shortwave.

Then ridge builds ahead of aforementioned trough next weekend.

Dry forecast until Saturday night Sunday. Capped pops at high chance
Sunday due to timing uncertainty.

Temperatures return to near normal as CAA ensues behind the cold
front. It may take some time for the colder air to settle in, which
likely happens behind sfc trough associated with second shortwave,
so readings may eclipse seasonal norms Wednesday before falling back
closer to seasonal norms Wednesday night through Friday.

Then temps rebound to above climo in return flow ahead of trough,
cold front next weekend.

Due to this warmup, plain rain is expected with the next system.

Aviation 18z Monday through Saturday
Difficult forecast for the nyc and long island terminals as a
warm front just to south of the area this afternoon lifts
through late tonight. For the nyc and long island terminals.

Ceilings will likely remainVFR, but an occasional MVFR ceiling
can not be ruled out. For the connecticut and lower hudson
valley terminals, there is higher confidence for MVFR ceilings
becoming ifr toward evening. Ifr ceilings are forecast to
develop across the remaining terminals late tonight. Any
improvement tomorrow is forecast to be gradual. Moderate to
heavy rain showers and isolated thunderstorms will impact the
area from daybreak through the afternoon with the approach of a
cold front.

Winds will be E NE at 5 kt or less, except for those terminals
near long island sound where the flow will be closer to 10 kt
this afternoon. Winds veer to the SE then S late tonight into
Tuesday morning as warm front pushes north of the region.

Llws compression likely Tuesday with gusts up to 35 kt possible,
strongest for kisp kgon. Cold frontal passage with wind shift
to west will occur from mid to late afternoon.
