Synopsis
High pressure will remain overhead through Wednesday. Low pressure
will impact the region Thursday into Friday. High pressure will
build in for the second half of the weekend, followed by a cold
frontal passage early next week.

Near term until 6 am Wednesday morning
A few adjustments for this evening's update, mainly with respect
to dew points. Also adjusted cloud cover, with sharply
decreasing cloud cover towards midnight, followed by mainly
clear skies into early Wednesday morning. Far northern areas may
lose the clouds a couple of hours later than locations closer to
the coast. Due to the sea breeze also adjusted the winds with a
blend of WRF arw and lav as they have painted the winds better
over the past few hours and seem very reasonable going forward
based on what happened last night under a very similar set up.

With high pressure building overhead during the overnight would
expect good radiational cooling. Based on last night most
stations lost clouds approaching midnight, and expect the same
for the most part for tonight. Therefore did not adjust
temperatures all that much as what was issued earlier looks to
be on track. Temperatures tonight will be in the lower to middle
20s across inland areas and the pine barrens, with mainly the
lower to middle 30s in the immediate new york city metro area.

Short term 6 am Wednesday morning through Wednesday night
Quiet conditions expected on Wednesday as high pressure moves
offshore. A return flow around to the south will allow for milder
temperatures on Wednesday, with highs in the upper 40s to lower 50s.

A cold front to our west will then increase chances for
precipitation late Wednesday night as it approaches the area.

Temperatures Wednesday night will be in the 30s to near 40.

Long term Thursday through Tuesday
The 12z models are coming into good agreement that a deepening low
will track roughly thru nyc Thu ngt into early fri. This will
produce mainly rain over the area Thu and early fri. There could be
a little mixing across the interior at the onset if the pcpn arrives
early enough Thu mrng. As the low pulls away, a dry slot will cut
the rain off Fri mrng, with perhaps some dz and fog settling in,
then as the upr low approaches some shwrs possible midday into fri
eve.

Cold pool aloft builds in on sat, resulting in highs blw normal and
sct-bkn CU development. Wly flow aloft develops on Sun and heights
rise, resulting in a quick but solid warming trend. Highs flip to
abv normal a a result.

A cold frontal passage appears on track for mon. The models are in
good agreement wrt timing, but the GFS brings the core of the cold
air swd, as opposed to the ECMWF which keeps it in canada. The
result is that the GFS would be more of an arctic fropa, with the
ecmwf more benign. Temps should soar ahead of the front with wsw
flow and compressional heating. The fcst may be too low ATTM with
consall used.

Temps spring back blw average on Tue with a colder airmass building
in. Dry wx with high pres expanding into the region.

Aviation 00z Wednesday through Sunday
Vfr with high pressure over the terminals.

Nw-w flow around 10kt backs s-sw for most terminals this
afternoon evening. Winds becoming light and variable for most
terminals after 00z.

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.
