Synopsis
A low pressure system will move off to our east tonight and
higher pressure will begin to build in. The high will dominate
our weather through Wednesday with fair weather and seasonable
temperatures. The weather will turn unsettled for the latter
part of the week as a slow moving low pressure system approaches
and moves across the region bringing a widespread rainfall to
the area.

Near term /until 6 am this morning/
As of 100 am edt... Occluded front is now just east of most of
the forecast area with any rain showers limited to just eastern
new england. With the front now east of the region, no more
precip is expected overnight, so have lowered pops across the
entire region.

Despite being behind the boundary, plenty of clouds look to
remain tonight thanks to little low-level flow and lots of low-
level moisture remaining in place. IR satellite imagery shows
plenty of clouds remaining upstream as well, although most of
these clouds are mid and high level in height. Skies will
generally be overcast overnight, although a few breaks in the
lower clouds may be possible for late tonight. If any breaks do
occur, some radiational fog may form in these areas for the
overnight hours as well.

Lows will generally be in the 40s to low 50s, with the lowest
readings over the adirondacks and southern vermont and the
mildest temps for the capital region and mid hudson valley.

Short term /6 am this morning through Wednesday night/
Weak ridging will build in at the surface Tuesday and is
expected to remain over the area through Wednesday with fair
weather and seasonable temperatures. Guidance has come into
better agreement having a weak low pass well south off long
island Tuesday night into Wednesday with its associated
precipitation remaining well to our south and east. Aloft
some ridging will be induced over the region in advance of a
deepening trough to our west across the central conus. A low
pressure system will develop over the tennessee/ohio valleys in
response to the deepening trough. An upper low is expected to
develop Wednesday night as vigorous short wave energy rotates
about the base of the trough resulting in a nearly vertically
stacked system. Chances for showers will be on the increase
late Wednesday night as the system gradually approaches. There
are indications that secondary development may occur over the
delmarva region as the upper trough begins to become negatively
tilted.

Expecting seasonable warm temperatures during the day both
Tuesday and Wednesday along with light winds.

Long term /Thursday through Monday/
Confidence continues to grow in an unsettled pattern impacting
memorial day weekend. We start off with an amplifying trough from
the midwest moving into the northeast as a coastal low from the
gulf moves up the east coast Thursday. Just how much rainfall
we receive in addition to the potential for any thunderstorms
will be contingent upon how far north the system's warm front
travels. Past few days guidance shows the front only getting up
to nyc/coastal ct which keeps the majority of our CWA out of the
warm sector. Bufkit soundings only show limited elevated
instability in our far southern and eastern spots so put the
threat for thunder there. Still not certain on system's exact
speed but thinking that Thursday afternoon should be wetter than
the morning as showers move into our area from southwest to
northeast through the day Thursday. Given impressive 850mb jet
over eastern part of CWA and decent packing of isotherms, some
steadier periods of rain are possible.

By Thursday night, a dry slot should wrap into the low and provide
breaks of dry time; however, given that the upper level low should
still near the area, kept likely pops in the area. Diurnal
heating in addition to the upper level low cutting off and
moving over the northeast should allow showers to resume during
the daytime Friday so continued likely pops. The trough axis
should exit the area Saturday so lowered pops in south/west
counties but kept chance pop north/east. Ridging builds in for
the daytime Saturday so it should end by being a pleasant day
for most areas.

Watching another mid latitude cyclone moving into the great
lakes/northeast for Sunday/Monday. Given this is a week away, do not
have high confidence on exact timing of precipitation. Current
guidance suggests that the first half of Sunday should feature dry
time under increasing clouds before the threat for showers increase
late in the day into Monday.

Temperatures for the extended should average near to slightly below
normal with highs in the upper 60s to low-mid 70s most days and
above average precipitation amounts due to the unsettled pattern.

Aviation /05z Tuesday through Saturday/
Occluded front is through most of the region, ending the threat
for widespread rain showers. However, abundant low level
moisture remains in place. This low-level moisture will allow
for some low MVFR/ifr stratus this evening, especially at
kpsf/kpou. Some clearing will eventually make its way into the
region, allowing for some of the lower clouds to clear out after
midnight. However, this clearing may result in radiational fog
forming for later tonight, which may keep ifr conditions for
most sites for the late night hours. Kalb may only drop to MVFR,
as a larger t/td spread and a light breeze may prevent ifr
conditions from occurring there. Otherwise, winds will become
light from a west to northwest direction for the overnight
hours.

Any morning mist or low clouds should quickly dissipate after
sunrise due to the strong late may sunshine.VFR conditions are
then expected through the entire day on Tuesday with just some
passing high cirrus clouds which will linger into the evening
and light north to northwest winds at 5 kts or less.

Outlook...

Tuesday night: no operational impact. No sig wx.

Wednesday: no operational impact. No sig wx.

Wednesday night: moderate operational impact. Chance of shra.

Thursday: high operational impact. Likely shra.

Thursday night: high operational impact. Likely shra.

Friday: high operational impact. Likely shra.

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

Saturday: low operational impact. Slight chance of shra.

Fire weather
A low pressure system will move off to our east tonight and
higher pressure will begin to build in. The high will dominate
our weather through Wednesday with fair weather and seasonable
temperatures. The weather will turn unsettled for the latter
part of the week as a slow moving low pressure system approaches
and moves across the region bringing a widespread rainfall to
the area.
