Synopsis
A weak cold front stalls just south of the region this morning.

Low pressure developing over the ohio valley rides along this
front, passing south of long island on Saturday. Another wave
of low pressure moves along the stalled frontal boundary Monday,
south of the region. High pressure builds to the northwest
Sunday through Wednesday. The high weakens Thursday as a cold
front approaches from the northwest.

Near term until 6 pm this evening
Areas of fog developed this morning with locally dense fog,
especially across interior sections. The fog should be short
lived, and dissipate mid morning. Issued a special weather
statement for the fog through 13z.

The area remains in between systems today, as a weak cold front
settles south of the area this morning and a shortwave diving
out of the upper midwest induces surface low development over
the ohio valley by this evening. In the meantime, light winds
early this morning have resulted in the development of patchy
fog across parts of the lower hudson valley and connecticut.

This should begin to lift around daybreak.

Expect the majority of the daylight hours today to remain dry
with high temperatures near normal for late july, in the low to
mid 80s.

Short term 6 pm this evening through 6 pm Saturday
As the developing surface low emerges off the DELMARVA coast
this evening and rides northeast along the stalled frontal
boundary, rain will overspread the area from southwest to
northeast around or shortly after sunset. Models continue to
indicate that the heaviest rainfall will be focused south of the
area, with a tight precipitation gradient on the northern edge
of the system. With this in mind, lowered QPF amounts for the
entire region. However, any northward adjustment in the track
of the low would bring higher rainfall totals back into the
local area. With precipitable water values expected to be in the
1.5-2 inch range, such a scenario would also increase the
flooding threat.

Rain begins to taper off late Saturday morning, although the
weather will remain somewhat unsettled overall as the upper
trough lingers over the area. In addition, wind gusts of 25-35
mph are possible on Saturday as the low passes south of the
area. With plenty of cloud cover, temperatures during the day on
Saturday will remain below normal, generally in the 70s.

Long term Saturday night through Thursday
An upper trough will remain along the eastern sea board Saturday
night into Tuesday as energy rotates through the trough, and an
upper level jet remains on the eastern side. The trough moves
little as a western atlantic ridge remains in place.

Some uncertainty remains with the forecast Saturday night into
Sunday as the trend has been for the low to track farther south with
the latest model runs. Currently the precipitation will be winding
down Saturday night as the low moves south and east of the region.

Another low is expected to develop across the mid atlantic region
late Sunday night into Monday and also track south and east. Again,
there is uncertainty as to where this low will track. Currently
precipitation will be possible, east of new york city, Sunday night
into Monday night.

The upper trough does weaken Monday night into Tuesday as the flow
until Wednesday night into Thursday when another shortwave rotates
into the northern flow and re amplifies the trough along the coast.

At the surface high pressure builds to the northwest Monday night
and Tuesday, then weakens as a cold front develops in response to
the digging shortwave, and brings a cold front to northwest of the
area during Thursday. Will mention thunder ahead of the cold front
as the area become marginally unstable.

Aviation 11z Friday through Tuesday
A weak cold front slowly moving through the area this morning
will stall south of long island later today. Low pressure
develops over the central appalachians this aftn... Tracking to
the mid-atlantic coast tonight.

MVFR to ifr for an hour or so... ThenVFR returns and prevails at
least into the eve. Weak cold front appears to be just N of long
island and nyc terminals as of 11z.

06z guidance continues to trend rain to the south... But have not
jumped on this just yet. Want to see the 12z model suite. Onset
may need to be pushed a few hours later and duration shortened.

MVFR to ifr also expected to return tonight... But timing is
uncertain.

Moderate confidence in winds. Pseudo seabreeze possible at the
coast this aftn.

Ny metro enhanced aviation weather support...
