Synopsis
A cold front will approach today and pass offshore by Friday
morning. High pressure builds to the north this weekend and
across the canadian maritimes early next week. A frontal system
approaches by mid week next week.

Near term through tonight
The forecast is mainly on track with minor adjustments made to
hourly forecast elements as needed.

A cold front approaches today. Ahead of this front, hot and
humid weather will continue. A prefrontal trough over the
hudson river valley will remain nearly stationary, before being
forced to the east this evening. Behind the trough, dewpoints
will end up lower for the second half of the day as the low
level flow comes in off the land. Elsewhere, dewpoints in the
70s will remain locked in.

No changes to the heat advisory with the heat index still
expected to be around 95 for much of the area.

The area is in a marginal risk for severe for this afternoon and
evening. The increasing shear late supports organized cells.

However the models depict some NVA coming through at peak
heating, so this may suppress development for most of the day.

The jet gets close enough to support activity tonight. Some of
this could be strong to severe, mainly the southern third of the
area, until the front comes through. Thereafter, showers are
possible with the jet still providing upper level divergence.

There is a moderate rip current risk today.

Short term Friday
Lingering morning showers are possible per the 00z nam, GFS and
ecmwf. Although the upper jet will be supportive of activity
through the day, the stable airmass building in will counteract
this. As a result, clearing is expected to occur from the
northwest through the day, and temperatures will mix out to
around 80. The humidity will be much lower with the drier
airmass building in.

There is a moderate rip current risk Friday.

Long term Friday night through Wednesday
Models, except the nam, are in general agreement with handling of a
sw to NE oriented trough and eventual closed low over the northeast
this weekend, as sfc high pressure builds to the north.

Dry, cooler and less humid air will be ushered in for the weekend,
with temperatures several degrees below normal. As the upper low
passes overhead by Sunday, the sfc high moves east and easterly wind
flow will moisten the lower levels of the atmosphere. With this
increase in low level moisture and upper cold pool overhead, a pop
up shower is possible on Sunday. This upper low traverses east as
next trough begins to approach from the upper mid west early next
week. This upper trough slowly lifts north in central canada, so do
not foresee a huge rain event by mid week as sfc frontal boundary
weakens as it approaches due to lack of upper support.

As such, generally dry weather conditions are anticipated early to
mid week next week.

As mentioned, cooler than normal temperatures can be expected this
weekend, and possibly into Monday. These temperatures begin to creep
up closer to normal as the upper low passes east toward mid week
next week.

Aviation 15z Thursday through Monday
A cold front will move through late tonight into Friday.

MainlyVFR and dry conditions expected this afternoon. Showers
and thunderstorms are possible late this afternoon with the
highest chances later this evening moving from NW to se. With
these, brief MVFR to possibly ifr conditions as well as
potentially gusty winds will be possible. Not confident enough
to put in tempo groups yet, left as prob30 or could very well be
vicinity for thunderstorms.

Regarding winds, SW flow of 5-10 kts for most terminals
initially will become more S with sea breeze development in the
afternoon with a slight increase in wind speed. A few gusts to
15-20 kt will be possible late afternoon into the early
evening along the coast. Winds will become more w-nw at 5-10 kt
tonight after the cold frontal passage.
