Synopsis
High pressure will continue to build eastward and become nearly
stationary off the mid atlantic coast, while a warm front passes
well to the north. The offshore high will dominate from Friday
into Saturday before a cold front moves through on Sunday. The
front may then become stationary just to the south early next
week.

Near term until 6 am Thursday morning
Forecast is on track. Just some minor updates to t TD and sky
based on latest obs and trends. Instability CU continue to
dissipate with the loss of heating, so expect a mostly clear
night. Thin high clouds arrive this evening, then also some mid
level clouds as a mid level vort MAX outruns a flattening upper
ridge to the west. Lows tonight should be close to or a few
degrees below MOS guidance mins, with 55-60 well inland and
across much of eastern long island, and 60-65 elsewhere.

Short term 6 am Thursday morning through Thursday night
The pressure gradient will tighten up by afternoon as the high
moves out over the atlantic, and as a warm front out ahead of
low pressure in the upper great lakes sets up across upstate ny
and new england, s-sw winds will increase to 15-25 mph with
gusts 30-35 mph, and it is quite possible that much of long
island and southern ct could see peak wind gusts close to 40 mph
late in the afternoon. Temps away from immediate south-facing
shores should peak in the 80s, though if the stronger southerly
flow kicks in sooner than expected, much of long island may not
make it out of the 70s. Highs in urban NE nj may approach 90.

Dangerous rip currents are expected at the ocean beaches,
particularly in the afternoon and evening.

For Thu night, with the warm front well off to the north do not
expect much of any precip, though eastern areas could see some
mid level clouds as an area of mid level moisture and weak
instability rides across. It will also be warmer and more humid
than recent nights, with lows 65-70.

Long term Friday through Wednesday
Bermuda high pressure will continue to usher in warmer and more
humid air from Friday into Sunday. There is a chance for showers
and thunderstorms each period, with the better chances during
the afternoon and early evening both Saturday and Sunday.

Drier and less humid conditions return on Monday with the next
chance at showers and storms on Tuesday and Wednesday.

Temperatures Friday and Saturday will be in the upper 80s with
increasing humidity levels. A few 90 degree readings are also
possible in the nyc metro and NE nj. MAX heat indices look to stay
in the lower 90s both days at this time at these locations, with
upper 80s elsewhere. Closer to the coast, onshore flow will keep
highs in the lower to middle 80s. Temperatures should be a bit
cooler on Sunday in the lower and middle 80s due to increasing
clouds and higher coverage of showers storms. Highs should
gradually fall back closer to normal early next week.

Aviation 23z Wednesday through Monday
High pressure slowly drifts offshore tonight and Thursday.

Vfr. Wsw-sw winds under 10 kt tonight once sea breeze influence
wears off. For Thursday,VFR continues. SW winds eventually
increasing to 15-20 kt with gusts mostly around 25 kt. Strongest
and most southerly winds expected at kjfk and klga.

Ny metro enhanced aviation weather support...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
