Synopsis
High pressure across the region will depart the area today
as a warm front approaches. Clouds will be on the increase with
chances for showers moving in this afternoon and widespread
showers this evening into the overnight hours along with some
thunder possible. Warm on Sunday with mainly fair weather.

Memorial day will feature abundant sunshine and seasonable
temperatures.

Near term until 6 pm this evening
As of 646 am... A surface high was centered directly over the
area early this morning. Winds are calm wind and skies mainly
clear as clouds spill overtop the upper ridge. Have locally
dense fog in some areas especially in river valleys. Conditions
will improve by mid-morning. The surface high will quickly
shift southeast and off coast this morning allowing a warm front
to approach from the west. The upper ridge will begin flatten
as a short wave moves across the great lakes region. Clouds will
be in the increase with chances for showers moving into the
northwestern portion of the area by early to mid afternoon.

Today will be warm than yesterday as southerly return flow
develops about the departing high. Expecting highs in the lower
to mid 70s in the valleys below 1000 feet with 60s above 1000
feet.

Short term 6 pm this evening through Monday night
Increasing chances for showers as we head into the evening as
the warm front and its associated low level jet move into the
region. Can not rule out some thunder tonight as a layer
elevated instability moves across the region in association with
the warm front. With the system's short wave passing well our
northwest moving northeastward from the great lakes region, the
better and more widespread chances for showers will mainly north
of i-90. With the upper flow flattened convection is expected
to track further east and south through the evening.

The showers will taper overnight as the warm front lift through.

This will leave the area in the warm sector to start Sunday and
it will be a warm day. Highs into the lower to mid 80s up the
hudson river valley and into northwestern connecticut with 70s
elsewhere. Any 60s should be limited to above 2000 feet across
mainly the southern adirondacks. Convection associated with
short wave rounding the top of the broad upper ridge approaching
from the ohio valley could graze the southwest portion of the
area during the afternoon however at this time only have slight
chance pops. Otherwise fair weather is expected as there is not
another trigger for convection.

Sunday night into Monday a northerly flow of drier and cooler
air will arrive as surface ridge axis slides east-southeast
across eastern canada. Expecting a tranquil day with abundant
sunshine and seasonable temperatures for memorial day. Clouds
will be back on the increase Monday night as another low
pressure system warm front approaches. Any threat for storms
should hold off until late Monday night early Tuesday morning.

Long term Tuesday through Friday
Some unsettled weather is expected Tuesday through Thursday but some
if not all our region will be in a warm sector Wednesday and at
least part of Thursday. So, temperatures should be warm Wednesday
and Thursday despite the chances for showers and thunderstorms.

First, on Tuesday, there is a decent consensus from sources of
guidance ensembles that increasing warm advection and low level
forcing along a northeastward retreating boundary layer thermal
gradient and leading edge of low level jet energy and wind shift
from south to west will support chances for showers and
thunderstorms during the day Tuesday. The timing is a little in
question as there are some timing differences in sources of
guidance ensembles, some favoring the morning and other guidance
suggesting Tuesday afternoon. The instability in the advancing zone
of warm advection may support strong thunderstorms and needs to be
watched. Highs Tuesday in the lower to mid 70s but mid to upper 60s
higher terrain.

There is an increasing consensus for warmer weather Wednesday with a
possible prefrontal trough over our region Wednesday afternoon. This
depends on how far north the warm sector can get. Boundary layer
flow will be west to west southwest and somewhat strong, suggesting
some downslope flow and at least some intervals of clouds and Sun to
allow for some daytime heating. There are indications of some degree
of an elevated mixed layer and enhanced instability but it is too
early to tell with a high confidence. If the warm sector does not
extend much into our region until Thursday, then the best chances
for showers and storms would be west and south of our region.

However, based on a consensus for boundary layer flow to be west to
southwest across the entire region, it suggests warmer weather has a
good chance of spreading through our entire region. So, including
scattered showers and thunderstorms for Wednesday afternoon and
evening with highs in the 80s and some 70s in higher elevations.

Upper dynamics and the associated cold front are expected to track
through our region Thursday. Once again, timing will be important
in determining how much we heat up during the day and if the
elevated mixed layer and enhanced instability will exist along the
zone of low level convergence, strong boundary layer winds and cold
front. Highs Thursday in the 80s but around 70 to mid 70s higher
terrain. Again, the potential for strong to severe thunderstorms
will have to be watched for Wednesday and Thursday since not only
are there some instability and forcing signals in guidance but the
end of may has some history that cannot be ignored either.

By Friday, there should be some clearing and drying with
temperatures reaching the lower to mid 70s but maybe a few upper 70s
in warmer spots and some 60s in higher terrain.

Aviation 12z Saturday through Wednesday
High pressure over our region today will drift off the coast today.

A warm front will approach from the southwest tonight.

The clear sky and calm winds have promoted fog development at kgfl
and kpsf that will dissipate by 13z. After about 13z,VFR conditions
as high clouds spread over the region through the afternoon. As the
warm front approaches this evening, showers will begin to develop
and track into our area. Showers and MVFR ceilings and visibilities
are an increasing likelihood this evening at kgfl, kalb and kpsf but
just prob30 at kpou. Showers are expected to decrease in coverage to
isolated after about 08z-10z but ceilings will hold in the MVFR
range while visibilities remain predominantlyVFR through 12z
light variable to calm winds through mid morning. Winds will become
southeast to south and increase to 5-10 kt by afternoon. Some gusts
up to, or greater than 20 kt could occur at kalb by late afternoon.

Steady south winds at around 10 kt by late afternoon at all taf
sites with gusts at kalb to around 20 kt through evening.

Outlook...

Sunday night: no operational impact. No sig wx.

Memorial day: no operational impact. No sig wx.

Monday night: moderate operational impact. Chance of shra.

Fire weather
Dry start to the day with chances for showers moving in this
afternoon with widespread showers this evening into the overnight
hours. Warm on Sunday with mainly fair weather. Abundant sunshine
and seasonable temperatures for memorial day.

Hydrology
Another round of showers will overspread the area this
afternoon into tonight. Higher QPF amounts are expected to the
north and west of the capital district where 1 2 to an inch of
rain is expected with amounts dropping off to about a tenth of
an inch across the mid hudson vally and northwestern connecticut.

Warmer for Sunday with mainly fair weather. Dry memorial day.
