Synopsis
A wave of low pressure will move along a stationary front
located to our south bringing some showers to the southeastern
catskills, mid hudson valley and northwestern connecticut
mainly this evening. A stronger low pressure system approaching
from the great lakes region will bring more widespread showers
along with some thunderstorms to the area Sunday evening through
Monday.

Near term until 6 am this morning
As of 1215 am edt... The local area continues to be sandwiched
between stationary fronts, with one located to our north across
far northern new york and the another to our south in the
vicinity of i-80.

High pressure over hudson bay will shift southward with the
stationary front to our north weakening. Meanwhile, a wave of
low pressure will continue to move eastward along the boundary
to our south. Some light rain showers have been ongoing across
central southern areas this evening, but with this precip
falling out a mid-level clock deck, these showers have been very
light and spotty. Will continue to allow for slight to chc pops
until the late night hours (especially for far southern areas),
but any rainfall will be rather light and won't amount to very
much.

Partly cloudy conditions are expected to develop across the
northern portion of the forecast area with mostly cloudy cloudy
skies across the rest of the area. Lows will be from the mid
50s to mid 60s. It will be muggy especially for areas south and
east of the capital district.

Short term 6 am this morning through Tuesday
Fair weather is expected for much of Sunday as the area is
between systems and some ridging builds in at the surface and
aloft. The ridging aloft will induced ahead of an approaching
trough and opening low. Guidance keeps this feature positively
tilted as it approaches and moves through. Showers will begin to
move into the area late in the day Sunday and will overspread
it at night with showers continuing through the day Monday. The
unstable air is expected to remain to our west and south with
some limited instability possible late Sunday night and Monday;
have slight chance for thunder during that time. The system will
be slow to move through so chances for showers linger through
most of Monday night with chances limited to the northeastern
portion of are into Tuesday.

Highs mainly in the 70s Sunday with some lower 80s up the hudson
river valley. Much cooler Monday with extensive cloud cover and
showers with highs only in the 60s with lower mid 70s in the
mid hudson valley. Highs a bit warmer Tuesday in the mid 60s to
mid 70s; below normal by around 10 degrees.

Less muggy and more comfortable sleeping weather especially
Monday night.

Long term Tuesday night through Saturday
The long term period will begin with dry weather on Wednesday,
transition to wet weather Thursday and Friday, then return to dry
conditions heading into the weekend.

Tuesday night and Wednesday... High pressure will build eastward from
the great lakes resulting in mostly clear skies and pleasant
temperatures. Highs on Wednesday will be in the upper 60s to mid 70s
north of the capital region and upper 70s south of the capital
region.

Thursday and Friday... Expect unsettled weather with a chance of
thunderstorms on Thursday as 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, the
ecmwf has a low pressure system developing to our south and moving
northeast while the GFS has a cyclone undergoing rapid cyclogenesis
off the east coast, therefore going with a chance of showers due to
the low confidence. Highs will be in the mid 70s to low 80s with
lows in the upper 50s to mid 60s.

Saturday... High pressure returns to the region bringing dry weather
and mostly clear skies. Highs will be in the mid 70s to low 80s with
lows in the upper 50s to mid 60s.

Aviation 05z 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 wave of low pressure will move along a stationary front
located to our south bringing some showers to the southeastern
catskills, mid hudson valley and northwestern connecticut
mainly this evening. A stronger low pressure system approaching
from the great lakes region will bring more widespread showers
along with some thunderstorms to the area Sunday evening through
Monday with total rainfall amounts of around an inch anticipated.

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

A wave of low pressure will move along a stationary front
located to our south bringing some showers to the southeastern
catskills, mid hudson valley and northwestern connecticut
mainly this evening. The heavy rain will stay be to our south.

region will bring more widespread showers along with some
thunderstorms to the area Sunday evening through Monday with
total rainfall amounts of around an inch anticipated.
