Synopsis
Low pressure will deepen over the mid-atlantic today, track through
the tri-state region tonight and into the maritimes on Friday. A
broad area of high pressures builds in for the first half of the
weekend, then a slow moving frontal system will bring the potential
for showers from Sunday into Tuesday.

Near term through Friday
Middle level drying is fast approaching from the south and west
early this afternoon. The back edge of the steady rain is now
moving through the nyc metro and will continue tracking
northward into the early afternoon. As the middle levels dry
out, we will be left with just a chance for light rain or
drizzle. Some uncertainty on whether or not there will be any
precipitation this afternoon, with the highest confidence in
continued low clouds and areas of fog.

Easterly winds will be gradually weaken this afternoon as the
pressure gradient slackens, but a few gusts up to 20-25 mph
possible near the coast early.

Attention then turns to the h5 low, currently over the ohio
valley and a vigorous piece of energy located across the
southeast. The upper low will swing this vorticity energy
towards the region tonight, with impressive dpva aloft and
steepening lapse rates in the middle levels. The models all
produce convective precip. As a result, showers and embedded
thunderstorms are expected overnight.

The upper low reaches the gulf of me on fri. This will allow
for decreasing coverage and intensity of showers through the
day. The downslope flow could allow for clearing, especially
along the coast, by the end of the day.

Temps will be below normal today, then will nudge closer on fri
as the rain ends. A blend of the guidance and raw model data
was used.

Short term Friday night through Sunday night
Weak ridging builds in Fri ngt and Sat which will attempt to
produce fair weather. There is a suggestion of shrtwv energy
swinging thru on sat. If this materializes, isold-sct shwrs will
be possible. A rainy day however is not expected attm. A broad
upr lvl low then drops into the midwest, producing SW flow aloft
across the fcst area sun. This will produce an increasing
chance for shwrs, particularly Sun aftn thru Sun ngt.

Temps will remain close to or blw normal thru the period. The
superblend was used.

Long term Monday through Wednesday
The upr low over the midwest will drive a slow moving frontal
sys thru the region for the beginning of the week. There is
some uncertainty wrt the timing, with the ECMWF slightly faster
than the gfs. Chance pops remain in the fcst.

Weak ridging builds in Tuesday, followed by more shortwaves
rotating around the S canada closed low, which has slid a bit
farther E into hudson bay NW ontario), Tuesday night and
Wednesday - with maybe some more isolated- scattered showers.

Temperatures should be within a few degrees of either side of
normal Sunday-Monday night, then run above normal Tuesday-
Wednesday.

Aviation 18z Thursday through Tuesday
An area of low pressure will move northeast over the region
tonight... And just to the northeast of the region Friday.

Ifr lifr CIGS continue into tonight. Potential for lifr
visibilities this evening in dz fog. Showers with a chance for
thunderstorms between 03z and 10z. Heavy downpours are the main
threat.

Gradual improvement to MVFRVFR CIGS Friday morning... With
quicker improvement toVFR vsby. Chance for showers.

Easterly winds 10-20 kt with gusts to 25 kt this
afternoon... Weakening this evening. Light and variable winds
tonight... Becoming northwest and gusty Friday morning.

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.
