Low pressure and its associated frontal system will track across the
region today through this evening, bringing some showers. Some
clearing is expected behind the system for late tonight into
Tuesday, before another system brings clouds and rain for mid to
late week.

Near term /until 6 pm this evening/
As of 1000 am edt, showers continue across the northwest portion
of the forecast area this morning with temperatures generally in
the upper 50s. Additional showers are expected throughout the
day today but most should be contained to the adirondacks,
mohawk valley, and the lake george saratoga region as a
shortwave rotates around an upper level low (positioned over the
northern great lakes). Also freshened up the hourly temps and
sky cover and sent updates to ndfd and web servers.

Prev disc...

as of 645 am edt, showers are beginning to shift mainly east of
the hudson river into western ma and southern vt. Only isolated
showers/patchy drizzle remain in the wake of these showers,
except scattered coverage across the western adirondacks.

These showers are being induced by a combination of
strengthening isentropic lift along the 295-300 k surfaces, as
well as QG forcing ahead of an embedded shortwave translating
east/northeast across eastern ny. This shortwave should pass
east of the region over the next 1-2 hours, with some
subsidence developing immediately in its wake. This should allow
showers to decrease in areal coverage for several hours this
morning from W to e. So, expect a period of only
isolated/scattered showers for much of this morning, with best
chances lingering across the western adirondacks.

For this afternoon, an approaching occluded front, as well as
additional upper level support from another shortwave
approaching from the west should allow additional showers to
increase in areal coverage once again. The greatest coverage is
expected for areas generally s/e of the capital region, as well
as across portions of the southern adirondacks and western
mohawk valley.

Some near-term hi-res models suggest a bit more in the way of
instability developing just ahead of the occluded front across a
narrow area of the western adirondacks and mohawk valley late
this afternoon, with mu capes reaching 100-300 j/kg. This could
lead to isolated thunderstorms, some of which could contain
locally gusty winds. Should more breaks in the cloud cover
develop, a greater risk for thunderstorms and strong wind gusts
would develop in this area. Elsewhere, no mention of thunder at
this time.

Since the areal coverage of showers is expected to decrease for
a period this morning, have trended high temperatures a bit
upward from previous forecast, with mid 50s to lower 60s
expected. However, some portions of the southern green mountains
and berkshires could hold close to 50.

It will be breezy in north/south oriented valleys, with south
winds gusting up to 25-30 mph at times.

Short term /6 pm this evening through 6 pm Tuesday/
Tonight, as the occluded front moves east, still some showers
possible along or just ahead of the boundary through around
midnight. In the wake of the front, winds should shift into the
west/northwest, with showers ending and some clearing possible.

However, there is a possibility that the boundary layer remains
fairly decoupled for a bit, which could allow low stratus and/or
areas of fog to form, particularly in sheltered valleys. Lows
should generally fall into the mid/upper 40s.

Tuesday, some slight low level drying is expected, particularly
across the southern adirondacks. However, a weak wave of low
pressure may develop along the frontal boundary to our south. At
the very least, this should spread a thick veil of high clouds
into the region for Tuesday afternoon, with somewhat thicker
clouds possible across the mid hudson valley northeast into nw
ct and the southern berkshires. Will have to watch how far north
and west an area of light rain expands with any possible wave.

Have indicated slight chance pops close to or just south of the
i-84 corridor for Tuesday afternoon, in case some light rain
affects this region with slightly stronger wave development.

Highs should reach at least the lower 70s in valleys and 60s for
most higher elevations. If clouds become thinner with a weaker
wave passing to our south, warmer MAX temperatures could occur.

Long term /Tuesday night through Sunday/
An extremely unsettled pattern is setting up during the long term
period as several short waves and a long wave trough will be in
place across the northeast for much of the time.

Tuesday night through Wednesday night... Scattered showers are
expected to overspread the forecast area during the second half of
Tuesday night and continue through Wednesday night as several areas
of low pressure move northeast from the ohio valley and mid atlantic
region into the northeast by late Wednesday night. Expect lows
Tuesday night in the upper 40s to mid 50s with highs on Wednesday in
the upper 60s to mid 70s and lows Wednesday night in the upper 40s
to mid 50s once again.

The remainder of the work week looks very unsettled as the low
pressure systems move through the northeast and off the new england
coast by Friday morning. The upper level trough axis will then pass
through the region on Friday bringing more showers. Highs on
Thursday are expected to be in the upper 50s to around 70 with lows
Thursday night in the upper 40s to mid 50s and highs on Friday in
the upper 50s to lower 70s.

Drier weather is then expected later Friday night into Sunday
although a stray shower cannot be totally ruled out. At least by
Saturday high pressure starts to build northeast from the mid
atlantic region before moving off the eastern seaboard on Sunday as
a warm front lifts northeast from the ohio valley. Expect lows
Friday night and Saturday night to be in the upper 40s to mid 50s
with highs on Saturday and Sunday in the mid 60s to mid 70s.

Overall expect temperatures to average slightly below normal with
precipitation much above normal.

Aviation /14z Monday through Friday/
Low pressure and an associated frontal system will track east
across the region today into tonight.

There could be a lull in the steadier rainfall this morning, as
precip becomes showery and more scattered in coverage.

Initially,VFR conditions will prevail. However, with a
persistent southerly flow off the atlantic ocean, MVFR
conditions for ceilings should develop later this morning into
the afternoon, as low stratus lowers CIGS to 1-3 kft for all
sites throughout the day. There could even be some patches of
MVFR br at kpsf/kpou as well. A more concentrated area of
showers looks to move through the afternoon and evening hours
ahead of the storm's occluded front. This will allow could
allow for another period of MVFR visibility and possible some
ifr as well.

The rain should taper off from west to east around sunset. Some
breaks in the mid level clouds may allow some areas of fog
and/or low stratus to develop after 00z/tue, with associated ifr

Winds will be mainly from the south to southeast at 5-10 kt
through today, with some gusts of 20-25 kt possible, especially
at kalb. Winds will shift into the west to northwest between
05z-08z/tue as the front moves across, at speeds generally 5-10
kt, although may be briefly gusty as the front passes through.


Tuesday night: low operational impact. Slight chance of shra.

Wednesday: moderate operational impact. Chance of shra.

Wednesday night: moderate operational impact. Chance of shra.

Thursday: high operational impact. Likely shra.

Thursday night: high operational impact. Likely shra.

Friday: moderate operational impact. Likely shra.

Fire weather
Low pressure and its associated frontal system will track across the
region today through this evening, bringing some showers. Some
clearing is expected behind the system for late tonight into
Tuesday, before another system brings clouds and rain for mid to
late week.

Low pressure and its associated frontal system will track across
the region through this evening. Showers will bring rainfall
amounts of one quarter, to three quarters of an inch, with the
greatest amounts expected across portions of the mid hudson
valley and NW ct, as well as across the southwest adirondacks.

Weak high pressure is expected to build across the region late
tonight into early Wednesday, with dry weather.

However, another slow moving low pressure system is expected to
bring periods of rain to the region late Wednesday into Friday,
some of which could be heavy. Latest mmefs suggest that only a
couple of river points reach/slightly exceed caution stage at
this time, but trends will need to be watched in case more
persistent heavy rain occurs with the approach of the slow
moving low pressure system.
