Synopsis for the long island waters and new york harbor.. High pressure settles in just north of the region today. Low pressure and a weakening warm front passes through tonight into Friday morning, followed by high pressure briefly building in late Friday and Friday night. A strong frontal system and associated low pressure will impact the coastal waters Saturday night through Sunday night. High pressure then gradually builds in during Monday.

Synopsis
High pressure ridging across the area today will move offshore
tonight. Low pressure and an associated cold front will cross the
area tonight and early Friday. More high pressure will follow for
Friday night and Saturday morning. A significant low pressure system
will cross the middle atlantic region Saturday night and Sunday.

Arctic high pressure will move in for the beginning of next week.

Another storm may affect the region for the middle of next week.

Near term until 6 pm this evening
930 am update: forecast is on track. Adjusted temperatures just
a bit to match current obs, then blended into existing forecast
based on a cloud cover over the area. Northerly winds are
starting to veer NE as expected, and a more easterly flow will
develop later today.

Previous discussion...

the cold front is finally making some progress across the CWA early
this morning, now generally south of the mason-dixon line. Near and
upstream of the front, skies rapidly clear (at least initially), and
dew points begin to drop. Downstream, a residual low cloud deck is
keeping temperatures much warmer (generally around or above
freezing), and winds remain more westerly or even southwesterly.

Given that models are struggling with the progress of the front,
their temp dew point output is not verifying well, especially where
the lower clouds have persisted most of the night so far. Have
needed to make several adjustments to both fields the past few
hours, but given the poor depiction of the front's progress so far,
have very little confidence in hourly temperatures dew points the
rest of the night. Most assuredly, this low confidence also applies
to sky cover, with the low cloud deck to the south of the front
poorly modeled in general and smaller areas of low clouds to the
north not simulated well at all. Expecting an increase in high
clouds late tonight as a weak perturbation approaches the area.

Large-scale lift via differential cyclonic vorticity advection aloft
will continue to aid in the increase and lowering of cloud cover
during the day, combined with increasing low-level isentropic ascent
late. Any residual cold advection from the cold front passing
through the area early this morning will cease rather quickly, but
the increased cloud cover should prevent much surface warming. Once
again, weighted the MAX temperature forecast toward the cold (i.E.,
ecs and met mos) statistical guidance. There should be little
diurnal upswing today given the above.

No precipitation is expected through late this afternoon, though
some light snow should be on the western doorstep by early
evening.

Short term 6 pm this evening through 6 pm Friday
A weak midlevel perturbation will be moving through the region
tonight, and large-scale lift immediately downstream will generate
light snow for much of the night across the area. The low levels
will be dry initially, but fairly potent warm advection in
combination with some jet dynamics (via the left exit region of a
250-mb jet streak approaching the southeast coast) will be the
sufficient ingredients for the precipitation. Surface temperatures
near and east of the urban corridor will be near freezing, so there
will likely be a mix of rain and snow in portions of new jersey and
also delmarva. To the north and west, conditions look cold enough
for snow throughout the event.

The consensus QPF is generally 0.1-0.2 inches, so snow amounts of 1-
2 inches seem probable northwest of the urban corridor, with lesser
amounts southeast where surface temperatures will be at least
flirting with freezing and precipitation may begin to mix with rain.

Notably, I sided with the somewhat colder guidance (nam, rgem, cmc,
icon), as the GFS tends to be too aggressive scouring the near-
surface cold air too quickly. Confidence is on the low side, though,
since antecedent cloud cover may prevent much of a temperature fall
from today's readings (which should be above freezing southeast of
the fall line). Presumably, sublimation and wet-bulbing effects will
cool the low-level profiles sufficiently for mostly snow in the
urban corridor into adjacent portions of new jersey southeast of i-
295. However, the stout warm advection will be warming the profile
with time, so some transition to rain should be expected near the
coast and (with time) farther to the northwest. As such, kept totals
generally less than an inch southeast of i-95 (to basically nothing
near the immediate coast). Not expecting much besides rain or snow,
though there is a chance the warming aloft could precede that at the
surface, giving a small window of sleet or freezing rain in delmarva
and new jersey. Any effects should be minimal and short-lived,
though, and confidence is not high enough for inclusion in the
forecast.

The timing of the precipitation looks to be after the Thursday
evening rush and before the Friday morning rush. Combined with the
sub-advisory snow totals expected, feel there is no need for
headlines with this event at this time, though cannot completely
rule it out in later forecasts. Untreated roads will likely be snow-
covered on Friday morning, however, so some travel impacts should be
expected, especially northwest of the urban corridor.

Precipitation rapidly moves eastward Friday morning, and the
afternoon should be dry everywhere. Sky cover is expected to
diminish slowly with time (except for the northwest cwa), and
temperatures will likely warm above freezing in most locations
by afternoon. I did keep the MAX temperature forecast on the low
side of guidance, given that snow may curtail some of the
diurnal heating and cloud cover may linger longer than currently
expected.

Long term Friday night through Wednesday
High pressure across the area for Friday night and early Saturday
will move away Saturday afternoon. Fair weather for these time
periods with increasing clouds Saturday. Temperatures a little below
normal with 20s Friday night and 30s (north) and low 40s (south) for
Saturday.

The big action of the long term begins later Saturday as
strengthening low pressure advances across the tn valley then across
va nj by Sunday morning. Significant moisture and dynamics will
produce abundant amounts of precipitation across the forecast area.

Overall (melted) QPF is in the 1.5 to 3.0 inch range for the
period ending 00z Monday. The 3 major op models have the greatest
qpf across cntrl nj with the ec having the greatest totals and the
canadian and gfe about 25% to 50% less. Much of what will fall
across the delaware valley and S E will be rain while the southern
poconos and NRN nj will have mostly snow. Significant totals are
expected for this (3rd) day event so while watches have not been
issued now (mainly not to confuse issues with the short near
system), we are rather confident that they will be issued later
today or tonight, at least of the N W areas. Snowfall in these areas
could easily be 6 to 10 inches thru Sunday. Other factors to
consider will be how much mixed precip (sleet or perhaps some
freezing rain) may occur Saturday afternoon and evening as the
warmer air arrives.

Behind the departing low Sunday, much colder air is ushered
southward across the region. Temperatures at dawn Sunday will be the
highs for the day and readings will fall 15 to 30 degrees by sunset,
reaching the teens (north) and 20s (s e). Wind chills will become
dangerously cold by Sunday evening and a quick freeze of standing
water is expected. Prepare now (!) for several days of dangerous
cold, large icy patches on roads (even where precip is all rain) and
significant amounts of snow the N W areas. A good reference to
prepare is : https:
