Synopsis
A strong low pressure system approaching from the great lakes
region will bring widespread showers to the area tonight into
Tuesday. There may also be scattered thunderstorms around Monday
afternoon and evening. Drier weather is expected during the
middle of the week as high pressure builds across the region.

Near term until 6 pm this evening
A stationary front was sagging south from northern new york
early this morning while a second stationary boundary was across
pennsylvania through new jersey and south of the long island
coast. For today expect the stationary boundary to the north to
wash out as it slides southward while a wave of low pressure in
the eastern great lakes will start to move southeastward into
central pennsylvania by days end. What all of this means for us
is that skies will be mostly cloudy to cloudy with gradually
increasing chances of showers this afternoon. Highs will be in
the 70s to around 80 in most places with some upper 60s across
the highest terrain.

Short term 6 pm this evening through Tuesday
For tonight and Monday... A second area of low pressure will form
across the eastern great lakes this evening as the first area
of low pressure passes to our south and east off the new jersey
coast. The area of low pressure across the eastern great lakes
will move into western ny late tonight. As a result of these two
system the forecast area will see increasing chances of
precipitation overnight such that by morning showers will be
likely to categorical. The precipitation may become heavy for a
time especially on Monday when thunderstorms are possible during
the afternoon and evening during which time showalter indices
go negative. The area of low pressure will move from western ny
into northern ny by days end. The slow movement of this system
will also add to the increased rainfall threat. Lows tonight
will be in the upper 50s to mid 60s with temperatures only
rising slightly on Monday into the upper 50s to around 70.

For Monday night and Tuesday... Only expect gradual improvement
as showers will continue to be likely for much of Monday night
with still a chance of showers for a good portion of the area on
Tuesday. The area of low pressure over northern ny Monday
evening will move east into the gulf of maine by Tuesday morning
as the upper level low it's associated trough and vort max
passes across our region during the late morning and early
afternoon hours of Tuesday. Lows Monday night will be in the 50s
to around 60. Highs on Tuesday will be in the upper 50s to lower
70s.

Long term Tuesday night through Saturday
The long term period will begin with dry weather Tuesday night into
Wednesday, transition to wet weather Thursday and Friday, with
gradual improvement possible Saturday.

Tuesday night into Wednesday night, high pressure will build
eastward from the great lakes resulting in mostly clear skies and
pleasant temperatures. Highs on Wednesday range from the upper 60s
to mid 70s across higher elevations, with mid to upper 70s for most
valley areas. Lows Tuesday night will mainly be in the 50s. Some
clouds showers may reach extreme NW areas toward daybreak Thursday,
ahead of the next incoming frontal system. Latest guidance suggests
a slowing trend with the approach of this system, so no higher than
low chc pops late Wed night across the western adirondacks. Lows wed
nt mainly in the 60s, with some 50s across higher terrain.

Thursday through Friday night, expect unsettled weather with
scattered showers thunderstorms on Thursday as a cold front
progresses to the southeast out of canada. This may become a system
of interest in the upcoming days as the gfs ECMWF are suggesting
modest instability, steep mid-level lapse rates, and negative
showalter indices. On Friday, both the 00z 23 gfs, ECMWF and at
least several GEFS members suggest a wave of low pressure may
develop along the frontal system. Therefore continuing with
scattered showers thunderstorms into Friday. Highs will be in the
mid 70s to low 80s with lows in the upper 50s to mid 60s.

Saturday, latest 00z 23 guidance has become more progressive and
backed off on idea of potential mid upper level low closing off over
region. Still, enough cold air aloft and cyclonic flow could allow
at least isolated scattered showers, so will keep low chc pops into
Saturday to account for this, with overall low confidence. Highs
should be mainly in the 70s to lower 80s, except for upper 60s lower
70s across higher elevations.

Aviation 07z Sunday through Thursday
Vfr conditions are generally expected to be in place tonight
into Sunday evening. However, a few periods of MVFR ifr could
occur at kpsf through at least 08z sun, as breaks in the mid
level clouds develop, allowing some patchy ground fog to develop
before winds increase behind a weak frontal passage.

Otherwise, based on the latest IR satellite imagery, sky cover
will generally continue to be bkn-ovc tonight. Ceiling heights
have been around 10-15 kft this evening, and these should
continue overnight, although may briefly drop to around 5 kft as
a weak cold front settles south. There could be a few light
spotty rain showers sprinkles at kpou through 08z sun, but this
should have little to no impact on visibility, so will just
mention it as a vcsh for now. Winds will be light variable,
trending into the northeast toward 12z Sun at less than 6 kt.

It should be dry for Sunday, although clouds will stick around,
with bkn CIGS around 10-15 kft. Light NE to E winds will be
around 5-10 kt. More widespread rain showers will return to the
region for later Sunday evening and overnight.

Outlook...

Sunday night: high operational impact. Likely shra... Tsra.

Monday: high operational impact. Likely shra... Tsra.

Monday night: moderate operational impact. Chance of shra.

Tuesday: low operational impact. Slight chance of shra.

Tuesday night: no operational impact. No sig wx.

Wednesday: no operational impact. No sig wx.

Wednesday night: low operational impact. Chance of shra... Tsra.

Thursday: moderate operational impact. Chance of shra... Tsra.

Fire weather
A strong low pressure system approaching from the great lakes
region will bring widespread showers to the area tonight into
Tuesday. There may also be scattered thunderstorms around Monday
afternoon and evening. Drier weather is expected during the
middle of the week as high pressure builds across the region.

Total rainfall amounts through Tuesday are expected to be around
an inch in many areas.

Hydrology
Hydrologic problems are not anticipated over the next few days.

A strong low pressure system approaching from the great lakes
region will bring widespread showers to the area this evening
into Tuesday with some scattered thunderstorms Monday afternoon
and evening. Total rainfall amounts of around an inch
anticipated.
