Synopsis
High pressure will build and remain in control through early
next week.

Near term until 6 am this morning
Clear skies and light winds have allowed temperatures to
continue to fall quickly across outlying areas. Adjusted
temperatures and winds to better match current observations,
otherwise the forecast remains on track.

Still expecting a mainly clear night with just a few mid and
high level clouds moving across overnight. Radiational cooling
will be efficient as winds are light, resulting in a vast range
of lows from near 50 in some rural and interior places to upper
60s in much of nyc.

Short term 6 am this morning through 6 pm Friday
Daytime heating under mostly sunny skies on Thu should result
in development of a weak lee thermal trough, while a lobe of the
building high still manages to build just to the south over the
cooler ocean waters, allowing for afternoon coastal sea breezes
to develop. Meanwhile, sunshine deep mixing to about 800 mb, and
weak downslope flow should allow for temps to rise to the upper
70s and lower 80s.

An approaching upper trough Thu night with accompanying mid
level vort MAX and band of mid level moisture should produce
mostly cloudy skies and possibly some sprinkles. Specific timing
of these clouds and any sprinkles is still a little uncertain,
and if the slower 12z NAM is correct, would take place overnight
than a couple hours either side of midnight.

Low temps are slightly warmer than MOS guidance due to the cloud
cover, ranging from the mid 50s to mid 60s.

Long term Friday night through Wednesday
High pressure will be centered over the great lakes region on Friday.

At the same time, an upper level trough axis will be right over us
in the morning. The flow aloft becomes less cyclonic through the day
as the trough shifts east, and with limited moisture, not expecting
any showers to develop. Highs mostly 75-80 across the area with
850mb temperatures around 9c.

Saturday will be mostly sunny with surface high pressure building
in and more of a zonal flow aloft. High temperatures likely at or
slightly below those of Friday with slightly cooler 850mb temps
progged.

The surface high will be centered more to our north by Sunday, and
similar to Friday we start the day with an upper trough axis over us
which shifts east through the day. Moisture is still limited, so
another dry and mostly sunny day. Highs in the mid to upper 70s.

High pressure will then be centered over new england on Monday and
Tuesday. This will continue the stretch of dry weather with mostly
sunny conditions and high in the mid and upper 70s.

There's a large spread among the global models regarding the
potential development and movement of a coastal low pressure system
during Wednesday. With high pressure likely to be centered somewhere
off the new england coast and a lack of a surface trough or cold
front for any sort of moisture entrainment, will go with the idea
that rain trying to move in here from the south remains suppressed.

Not a high confidence forecast this far out in time.

Aviation 06z Thursday through Monday
Vfr as high pressure builds in. NW winds become N tonight with
speeds under 10 kt. A surface trough develops over the area
Wednesday aftn which will result in a tricky wind forecast.

Boundary layer winds appear weak enough for seabreeze
development at coastal terminals, but most hi-res guidance is
indicating the sfc trough dominates the wind directions. Thus,
have decided against including seabreezes in the 00z tafs.

Outlook for 00z Thursday through Monday
Thursday-Monday Vfr.

Marine
High pressure will maintain quiet conditions through Sunday. The
pressure gradient may tighten and increase winds a little on
Monday due to a potential storm well the south, which may also
bring in an easterly swell. Ocean seas are still expected to
remain below advisory levels.

Hydrology
Dry through at least early next week.
