Synopsis
High pressure over the northeast and mid atlantic states will
drift offshore today. A warm front will approach this evening
and move north late tonight into Friday morning. A cold front
approaches Friday, moving across the region late Friday night
into early Saturday. High pressure returns on Sunday into
Monday before a series of troughs and a cold front pass through
Tuesday into Wednesday.

Near term until 6 pm this evening
Minor updates to temperatures dewpoints and timing of
precipitation tonight, otherwise forecast still on track.

An upper ridge axis will remain west of the region most of the
day, moving into the northeast around 00z Friday. Meanwhile
surface high pressure centered over upstate new york will drift
to off the northeast and mid atlantic coasts. The next shortwave
to affect he region will move into the great lakes region. The
upper flow will be somewhat blocky as the ridge builds and
moves slowly east. Will be dry with increasing clouds late in
the day as the ridge axis moves into the region.

There is a moderate risk for the development of rip currents at
the ocean beaches today.

Short term 6 pm this evening through Friday night
The upper ridge axis passes to the east and builds tonight into
Friday night as the upper pattern remains rather blocky as
heights rise as the ridge moves into the northern atlantic.

This will keep the shortwave from moving east and lifts into
southern canada and weakens as yet another moves into the upper
mid west and then into the great lakes region Friday night. At
the surface low pressure over the upper midwest will rotate
slowly into ontario and western quebec through Friday night.

A weak warm frontal boundary increases today and slow
approaches from the southwest this evening. Precipitation will
be delayed until late tonight as the warm front slowly pushes
into the region as the parent low remains well to the west. Best
chances or precipitation will be across northeastern new jersey
into the lower hudson valley. The region becomes warm sectored
Friday as the warm front lifts through. CAPE and surface based
instability increase during the day as the cold front slowly
approaches. There may be a break in the precipitation of a brief
time once the warm front lifts north, and until the cold front
nears later in the day. Best instability will be inland as a
deep southerly flow keeps a marine layer across long island and
into southern connecticut. Best chances of thunderstorms,
possible strong, will be inland Friday afternoon into the
evening. Then the storms will weaken and move into long island
and southern connecticut Friday night.

Long term Saturday through Wednesday
Cold front moves through the area during Saturday with a chance
of lingering showers and thunderstorms in the morning. Models
then agree that the available moisture is probably too low for
consideration of afternoon showers and storms, especially since
a lagging upper trough and shortwave appear to be too late to
arrive for necessary lift and mid level instability. Will
therefore go with a dry forecast for the afternoon. Then with
stabilizing lower levels, the upper trough should pass through
dry during Saturday night. An even blend of mav nam MOS looked
good for temperatures.

High pressure builds in on Sunday and lasts into Monday as the
upper flow becomes zonal to anticyclonic. Dry weather for both
days with highs mostly in the mid 80s.

For Tuesday into Wednesday, low pressure tracks across
southeastern canada. This will bring a couple of pre-frontal
troughs here before a cold front eventually passes through
sometime most likely on Wednesday. Looks like the best
combination of moisture, lift and shear could be late day
Tuesday into Tuesday night. Will cap pops at chance Tuesday
through Wednesday for now given the timing uncertainty of the
surface features and sources of lift aloft. Highs generally in
the 80s both days.

Aviation 18z Thursday through Tuesday
High pressure will slide offshore this afternoon before a warm front
approaches from the southwest tonight. A cold front will
approach from late Friday.

Vfr this afternoon and early tonight before deteriorating conditions
late tonight into Friday.

Friday will be very unsettled with the threat of showers and
scattered thunderstorms in the morning and then again with the
approaching cold front late in the afternoon. Gusty winds and
MVFR ifr are possible with any heavier shower or thunderstorm.

Light southeast winds near 10 kt this afternoon become mainly
southerly overnight and Friday. Gusts to 25 kt possible Friday
afternoon across much the region but especially along the coast.

Higher gusts possible with any thunderstorm.
