Synopsis
High pressure will dominate through the weekend. A cold front
approaches on Monday and moves through Monday night. High pressure
follows for Tuesday and Wednesday.

Near term until 6 am Friday morning
High pressure overhead and low rh through the atmospheric column
lead to a clear sky tonight with light to calm winds. There will
however probably be some fog in the river valleys late at night.

Strong radiational cooling is anticipated to help low temperatures
drop into the upper 30s for some of the outlying suburbs, so a
little too warm to mention frost. Most of the suburbs should end up
in the 40s, with lows in the city mostly 50-55.

There is a high risk of rip currents at atlantic ocean beaches into
this evening due to long period swells from distant hurricane
humberto.

Short term 6 am Friday morning through Friday night
High pressure center slowly drifts towards the mid-atlantic coast
through the period with continued dry weather. Sunshine occasionally
mixes with some cirrus, but overall it will be a mostly sunny day.

Subsidence will continue to limit the mixing depth, however with the
top of the mixed layer forecast to warm up to around 17c, expecting
high temperatures to climb to around 80 for parts of nyc and NE nj.

Mid to upper 70s are expected for the rest of the area. Cirrus at
night probably prevents strong radiational cooling on Friday night,
so lows will be milder this time around.

There is a high risk of rip currents at atlantic ocean beaches on
Friday due to long period swells from distant hurricane
humberto.

Long term Saturday through Thursday
Dry and warm conditions this weekend are going to follow the recent
cooler than normal weather we have seen the last few days across the
tri state. An anomalously strong ridge will build over the eastern
us on Saturday. The axis of the ridge will gradually move towards
the western atlantic on Sunday. Surface high pressure centered over
the middle atlantic Saturday will move offshore on Sunday. High
temperatures on Saturday will be in the upper 70s and lower 80s for
most locations, with lower to middle 80s possible in the nyc metro
and urban NE nj. Temperatures on Sunday will likely be a few degrees
higher than Saturday, especially away from the coast. Onshore flow
may hold temperatures in the upper 70s across long island and
coastal connecticut. Dew points moderate through the weekend and
should be in the lower to middle 60s on Sunday making it feel more
humid.

Heights aloft begin to fall Sunday night as a shortwave trough
begins moving across the great lakes region. The upper trough then
moves towards the northeast Monday and then swings across new
england Monday night into Tuesday. The trough will send a cold front
towards the area on Monday and then cross the region Monday night.

The 12z guidance appears to be in fairly good agreement on the
general timing of the front. The front should then be offshore on
Tuesday. The atmosphere is capped on Monday ahead of the front so
have trended the highest pops to Monday night evening night with the
actual cold front. Instability continues to look marginal and have
left thunder out of the forecast for now. The best forcing also may
pass to the north and will continue to chance pops for now.

Temperatures on Monday remain above normal in the upper 70s and
lower 80s.

Ridging returns both aloft and the surface later Tuesday into
Wednesday. Temperatures trend down near seasonable levels and the
atmosphere dries out. The next front may approach Wednesday night or
Thursday, but deterministic models and ensemble means differ on the
amplitude of any troughing that may approach.

Aviation 21z Thursday through Tuesday
Vfr through the TAF period.

N NE winds 5 to 10 kt except S 10kt or less along the coast.

Otherwise winds become light and variable tonight before
becoming west near 10 kt on Friday.

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.
