Synopsis
Weak high pressure will slide across today, followed by a warm
front passing through tonight. An upper level disturbance will
approach on Friday. A series of fronts will then move across
the area through the middle of next week.

Near term until 6 pm this evening
Forecast is on track. Weak high pressure will slide across,
providing a mostly sunny day, though there could be an increase
in high and mid level clouds late as a mid level vort MAX spills
over the upper ridge to the west. Deep mixing under mostly
sunny skies with h8 temps 13-14c should result in another warm
day, with temps in the lower mid 80s.

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

Short term 6 pm this evening through 6 pm Friday
A warm front passing through tonight could produce an isolated
shower late tonight, with the better chances across SE ct as
isentropic lift with the front strengthens a little. Some hi-res
guidance indicates potential for some low stratus and or patchy
fog late as well. Low temps should range from the mid 60s
across easternmost long island ct, to the lower 70s in nyc
metro.

A lead mid level trough well in advance of any remnants of
tropical storm cindy will be approaching on Friday, accompanied
by a substantial increase in low level moisture in the morning,
with dewpoints in the lower 70s. Best forcing for any convection
should arrive late morning or early afternoon, and while
instability appears meager, with CAPE 500 j kg or less, winds
aloft may make up for this and lead to a few strong tstms,
especially from nyc metro north west. Had been concerned
initially about a potential tropical predecessor rainfall event
with the area on the poleward side of an upper jet streak
approaching from the west, but think this potential will be
greater to the west at least through daytime Friday.

Temps will only be a tad less warm than those fcst for today,
with upper 70s to mid 80s expected.

Long term Friday night through Wednesday
Nwp is in agreement that a broad upper level trough will remain
east of the rockies through much of the forecast period. The
trough begins to sharpen early next week, but there are
differences as to when the trough axis pushes east.

Could see some heavy rainfall Fri night into Sat if the stronger
nam 50-60 kt LLJ verifies. GFS is much weaker, around 30 kt,
and ec is around 40 kt. Increasing theta-e advection and an
approaching short wave pre-frontal trough should support rain
moving in during the evening, generally west of the city,
although may be too aggressive with likely pop and it may hold
off until after midnight. Pw should increase to 2+ inches fri
night into Sat as deep tropical moisture advects into the
area. There appears to be enough elevated instability for some
non-severe tstms, which could also aid in heavy rainfall
potential.

Rain continues Sat morning as the remnants of TS cindy are
forecast to ride along an approaching cold front. The front will
be slow to move through, but the heavy rain threat should push
east during the aftn.

Weak ridging then builds in into Monday providing dry and
seasonable weather.

The 00z ec has started to waver from other guidance on the
progression of the upper trough over the eastern us early next
week. After a dry cold frontal passage Sun night, another will
approach on Mon with the potential for aftn eve convection. Will
need to monitor trends for the rest of the forecast period as a
slower trough progression could keep unsettled weather into the
middle of the week. Current forecast reflects trof axis moving
through on Tue with a chc for showers. Have kept thunder out due
to limited instability.

Aviation 18z Thursday through Tuesday
Weak high pressure builds over the area today. A warm front crosses
tonight.

Vfr with typical sea breeze wind directions at 10-15 kt.

Ny metro enhanced aviation weather support...
