Synopsis
High pressure will dominate the weather pattern through the
weekend. A cold front may cross the region early next week.

Near term through Wednesday
Surface high pressure will remain north of the region tonight.

Meanwhile, an upper level trough will remain northeast of the
area. The combination of an increasing northeast flow and a
shortwave rounding the base of the trough will result in an
increase in cloud cover late tonight through Wednesday morning.

Tonight, will start off mostly clear skies but skies become
partly to mostly cloudy towards daybreak and continue through
much of the morning and into the afternoon, with some clearing
expected late. Despite the partly to mostly cloudy skies,
conditions will remain dry.

Temperatures may be tricky tonight especially across the
eastern half of the area, as initially clear skies will allow
for some radiational cooling before clouds increase. For now,
think the thicker cloud cover will move in late enough that
temperatures will be able to fall off quickly this evening
before remaining nearly steady towards daybreak. This will
result in lows ranging from the mid to upper 40s in typically
cooler outlying locations to around 60 in new york city.

Temperatures on Wednesday will then remain several degrees below
normal with a good deal of cloud cover and persistent northeast
flow. Highs will be in the 60s and lower 70s.

There is a moderate risk of rip currents at atlantic ocean
beaches for the remainder of the evening.

There is a high risk of rip currents at atlantic ocean beaches
on Wednesday due to long period swells from distant hurricane
humberto.

Short term Wednesday night
High pressure near the region Wednesday night will result in
clearing skies and dry conditions. Lows Wednesday night will
fall into the 40s and 50s.

Long term Thursday through Tuesday
Psuedo-omega blocked pattern late week with the region on the
northeast side of eastern us upper ridging in between deep western
us troughing and western atlantic troughing interacting with
hurricane humberto. This blocking eventually breaks down, with upper
ridging sliding eastward into the area this weekend, as humberto and
western atlantic troughing gradually shear ne. Western us troughing
gradually slides northeast towards the region Monday and through
Tuesday. At the surface, canadian high pressure builds overhead
Thursday, with sprawling high pressure establishing itself east of
the mississippi river for late week into the start of the weekend. A
weak backdoor cold front does appear to slide through the region
Saturday, with high pressure slowly sliding east Sunday into Monday.

Tranquil and moderating temps to near seasonable levels Thu and then
above normal Fri (mid to upper 70s), as center of high pressure
gradually slides to the south of the region. Potential for good
radiational cooling conds Thu night, with lows in the 40s across
outlying areas. A weak cold front move through Friday night, with n
flow early, giving way to return flow Saturday night into Monday
ahead of approaching shortwave cold front. Temps Saturday into
Monday should rise well above seasonable levels(lower to mid 80s),
with increasing humidity levels Sunday into Monday.

Next chance for measurable precip appears to come late Monday into
Monday night with approach of next trough, with better model
agreement on approaching shortwave energy on Monday and slide
through Tuesday.

Nhc track forecasts for humberto have been consistent in slowly
tracking it east and then northeast through the next 5 days, well
out to sea. The likely indirect impacts will be dangerous
rip longshore currents and rough surf at atlantic ocean beaches
starting Wednesday as long period swells and wind waves begin to
increase. Potential for high surf (5-9ft)late Thu into Fri as the
most energetic E SE swells arrive from humberto. Beach flooding and
erosion issues likely during the times of high tide Wed thru fri
with E to W sweep, but potential for dune erosion and localized
washovers looks to be low. Refer to the national hurricane center
for official forecast information on humberto.

Aviation 19z Tuesday through Sunday
High pressure continues to build in from the north through
Wednesday, while hurricane huberto tracks well offshore over the
western atlantic. This will keep the area under a prolonged
period of northerly flow.

MainlyVFR. There is a low chance of an MVFR ceiling in the
morning.

Northeast winds around 10 kts for the remainder of this
afternoon, veering a bit this evening at less than 10 kt, then
increasing to 10 to 15 kt on Wednesday. Gusts 15 to 20 kt
possible Wednesday, mainly east of the nyc terminals.
