Synopsis
High pressure moves across the region this morning and offshore
this afternoon. High pressure moves farther offshore tonight. A
cold front approaches from the west Tuesday into Tuesday night.

This cold front will move across the region on Wednesday. A
much drier and cooler airmass will move into the region for the
end of the week.

Near term until 6 pm this evening
Forecast mainly on track this morning with just slight
adjustments to temperatures and dewpoints to better match
observed trends.

Weak quasi-zonal flow aloft with main upper level jet stream
well northwest of the region.

Surface high pressure moves across the region this morning and
offshore this afternoon. Expecting a mainly dry day with just a
slight chance of showers and thunderstorms for far western
orange county late this afternoon. 850mb temperatures forecast
to reach near 15-16 degrees c. Surface temperatures forecast to
reach several degrees warmer than yesterday. Mid 80s to near 90
degrees f for much of the region with mostly sunny conditions
for most locations.

The sky cover forecast still contains some uncertainty for the
times of the partial solar eclipse, which should run from about
120 pm to 400 pm in nyc and peak at 244 pm. This deals with how
much cirrus moves in as forecast models show some convection in
pa developing as well as the sea breeze convergence and
resulting CU field and how expansive that gets.

Like previous forecast, a look at the hrrrx conveys a slight
decrease during maximum obscuration of Sun during eclipse, so
adjusted temperature a degree downward at 19z (3pm local time).

There is a low risk of rip currents today, becoming moderate
late today at atlantic beaches.

Short term 6 pm this evening through 6 pm Tuesday
Rest of the forecast shows high pressure moving farther offshore
and a cold front gradually approaching from the west. Upper
levels convey an upper level trough with its upper level low based
in ontario approaching the region. Continually more warm and
humid conditions are expected. Forecast has warmer temperatures
Tuesday, getting hot and humid for quite a few locations. Could
see heat indices up to 100 degrees in and around nyc.

Precip forecast remains near or below 30 percent for showers and
thunderstorms. Not much forcing but increasing instability and
possible lee trough forming Tuesday could provide focus for
convergence. Models are pretty minimal with forecast rainfall
amounts overall tonight through Tuesday. Weak trough evident in
lower levels late tonight into early Tuesday will lead to pops
more in low end chance for showers and thunderstorms and then
expecting much of Tuesday to be dry except for interior
locations which will have relatively higher chances for showers
and thunderstorms. These locations will be closer to lee trough
as well.

Long term Tuesday night through Sunday
A cold front approaches the region Tuesday night and pushes across
the forecast area on Wednesday. Expect cloud cover to increase and
showers and thunderstorms to develop and move across the region
through this time frame. By Wednesday evening, skies will begin to
clear and a much cooler airmass will be arriving.

Canadian high pressure builds into the region Thursday through the
weekend, providing dry and sunny conditions. Temperatures will
remain below normal as highs only reach the 70s to near 80 each day.

The dry and cooler conditions are expected to continue into
Monday.

Aviation 12z Monday through Friday
Vfr through the TAF period as high pressure remains in control.

Isolated shra tsra possible late evening for nyc nj and nw
terminals.

Sw winds will increase this morning into the afternoon, with
southerly sea breeze development at coastal terminals. Gusts of
15 to 20 kt likely this afternoon. SW winds diminish to less
than 10 kt this evening.

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.
