Synopsis
Seasonably mild today with morning sunshine giving way to clouds
increasing late in the day. A cold front will bring a few snow
showers to the north country tonight along with much cooler
temperatures for the beginning of the work week.

Near term until 6 pm this evening
As of 200 am, clear skies throughout the greater northeast amid
midlevel height rises ushering out the seasonably cold airmass.

Surface high is centered over WV with an arctic boundary across
central qc into lake superior. A modest pressure gradient is
being maintained locally between the two features, but the ridge
appears to be exerting enough influence to allow winds to go
calm over the typically less- windy parts of the region. Made
some adjustments to the temps based on current obs, but overall
lows look good in the teens over the north country and 20s
elsewhere.

Today, the arctic boundary continues its southward approach,
likely just north of our CWA by around 00z Monday. Meanwhile the
surface high will shift offshore. Between these features,
clear skies and the moderation of the airmass aloft will lead to
a quick warm-up with temperatures reaching 5-10f above normal.

High clouds will increase in coverage during the afternoon and
evening as moisture associated with a cutoff low over the
central plains gets entrained into the westerlies. Stratus ahead
of the arctic boundary will also filter into the north country
late in the day. Overall, a dry and seasonably mild day is
expected. Some potential for a downsloping temperature boost in
the capital district, but low-level winds are a bit veered from
ideal downsloping directions, so generally stayed closer to
blended guidance for high temps. Winds will be a bit breezy with
some gusts to 20-25kt in the afternoon, but nowhere near as
high as yesterday.

Short term 6 pm this evening through Tuesday night
The arctic boundary will continue to track southward through the
forecast area tonight as the leading edge of an expansive and
anomalously strong upper low edges toward the area. However, the
upper low will cease its southward motion, meaning the front
will lose some of its upper support with southward extent.

Additionally, the airmass will remain rather dry in advance of
the front, as the better moisture associated with the plains low
remains to our south. So, the thinking is that we will have a
band of snow showers along the front 00-06z Monday across the
southern adirondacks, but it will lose its coherence south of
there such that only slight chance pops are in the forecast.

Around a half inch of snow is possible over the southern
adirondacks and southern greens with minimal to no accumulation
expected elsewhere. The temperature gradient along the front
appears fairly strong, so we should see a nice temperature drop
tonight with teens and single digits over the southern
adirondacks. Meanwhile, the cold advection will be delayed and
not quite as strong when the front reaches the mid-hudson
valley, so lows should remain in the mid-30s there.

We remain in the cold advection pattern Monday into Monday night
as a strong surface high sets up over the western great lakes,
resulting in northerly northwesterly winds locally. The cold
advection will be offset by plentiful sunshine and diurnal
mixing during the day Monday. There are big differences between
the warmer MOS guidance and cooler 2m model temps Monday. Have
gone with a blend of the two with a slight nod toward mos
numbers. But temperatures should end up short of normal again,
especially the further north you go. Chilly but clear Monday
night as h850 temps bottom out at -10 to -15c (1 to 2 sd below
normal per naefs) and cold advection continues. It actually
appears a reinforcing shot of cold air will come in associated
with a shortwave trough.

Tuesday into Tuesday night, the high will gradually expand into
the area such that it will be located directly overhead on
Tuesday night. High temps Tuesday look similar to Monday, except
cooler for the mid-hudson valley. It's looking like 5-10f below
normal across the board. Clear skies should dominate. It looks
quite chilly Tuesday night with the high overhead leading to
ideal radiational cooling conditions.

Long term Wednesday through Saturday
Temperatures are expected to continue to moderate with near
seasonable readings Wednesday and above normal Thursday, Friday and
Saturday.

An expansive high is expected to be centered directly over the
region Wednesday morning then its expected to shift gradually off
the east coast over the next couple of days as a cold front slowly
approaches from the northwest. The return flow about the high will
bring warmer air into the region. Temperatures Thursday are expected
to be 10 degrees warmer than Wednesday with readings Friday another
5 degrees warmer.

As the cold front approaches Friday its forward progress is expected
to be slowed as the upper level flow parallels the boundary and an
area of low pressure is expected to develop along the boundary over
the plains. This low is then expected to move northeastward along
the boundary eventually reaching the northeast Saturday. Fair
weather is expected at least into Friday then chances for showers
are in the forecast as we head into the weekend. There are
differences amongst the guidance handling the movement and amplitude
of individual short waves which impacts the timing and track of the
low over the region over the weekend.

Aviation 08z Sunday through Thursday
Vfr conditions expected. High pressure centered over the ohio
valley will shift off the southeast coast this afternoon. A
cold front will be on the approach from the north and is
expected to move southward across the local area tonight.

Initially high level cirrus clouds are expected to stream over
the region with clouds thickening and lowering this evening as
the cold front moves into the region. Moisture will be limited
so no mention of showers in the tafs.

Winds vary in direction and speed this morning at the tafs.

Overall a southwest-west flow is to develop with it becoming
gusty by late morning into the early afternoon with gusts up to
20 knots. Winds will decrease in the evening and shift more to
the west as the cold front moves through.

Outlook...

Monday through Friday: no operational impact. No sig wx.

Fire weather
Sunshine today will lead to a quick warmup with temperatures
rebounding into the 40s and 50s. Winds will be not as strong as
yesterday but some gusts to around 20 to 25 mph are still
possible from the west-southwest. Rh values will fall into the
20s and 30s south of i-88 i-90, but remain in the 40s and 50s to
the north.

An arctic boundary slides across the region tonight with snow
showers mainly confined to the higher terrain. Temperatures will
be below normal Monday and Tuesday with rh values mainly falling
into the 30s during the afternoon along with moderate
northwesterly winds. A long period of dry weather is
anticipated through most of the upcoming week with moderating
temperatures by the middle and end of the week.

Hydrology
No hydrologic issues are anticipated this weekend and into all
of next week. Temperatures rebound above normal briefly today,
but go back below normal Monday and Tuesday, which should limit
snow melt. Precipitation forecast is hydrologically
insignificant through the week. A gradual moderation through the
week will likely result in snowmelt during the daylight hours
during the middle and end of the week.
