Synopsis
A cold front moves across today with another one following it
for Tuesday into Tuesday night. High pressure builds to the
south Wednesday. A warm front crosses the region late Thursday,
with warm, humid and unsettled weather Friday through the
weekend.

Near term until 6 pm this evening
On the large scale, a longwave trough remains west of the region
today. A subtle shortwave embedded within this longwave trough
with some slight height falls is expected by mid to late this
afternoon. This in combination with daytime instability allows
for a low potential for a shower or thunderstorm. This will be
confined to mainly north and west of nyc. At the surface, a cold
front will be moving across the region and weakening. Today's
highs were a combination of gmos and ecs, mid 70s to low 80s.

There is a moderate risk for the development of rip currents
today.

Short term 6 pm this evening through 6 pm Tuesday
The front will become weaker with time. Instability will become
more elevated but a lack of a trigger will keep mainly dry
conditions tonight. Lows tonight were a blend of gmos and mav,
low 50s to low 60s.

For Tuesday, starting in the morning, there will be abundant
clouds. The height falls will be accompanied by greater value of
positive vorticity advection during the day. The longwave
trough still is west of the region tonight into Tuesday but on
Tuesday the amplitude of this shortwave is higher. There
wavelength of the shortwave is getting less, indicating a
sharper overall large scale trough. The chances for showers and
thunderstorms will be higher than those of the previous day.

Another cold front moves across Tuesday. Temperatures were a
combination of gmos and ecs, mid 70s to near 80.

Long term Tuesday night through Sunday
Upper trough passes Tuesday evening, with weak ridge building
Wednesday. Upper flow flattens late in the week, becoming SW ahead
of midwest trough over the weekend.

At the sfc, high pressure builds Tuesday night, passing to the south
Wednesday. Low pressure passes across the great lakes region
Thursday, with warm front passing across the area by that time.

Thereafter, frontal boundary remains just to the north of the area
as low pressure rides along it, also passing north. Then next low
approaches ahead of upstream trough, passing north for the
latter portion of the weekend. Subtle placement timing differences
noted in medium range guidance.

In general, unsettled weather looks likely from late Thursday,
through the weekend. Scattered showers and thunderstorms can be
expected, with coverage higher during the daytime each day.

Instability appears to be weak Thursday, but builds thereafter per
operational gfs. Li's as low as -5 c with long narrow cape's and
increasing pwat's, over 2 inches by Saturday, in a unidirectional
flow supports potential for flash flooding - mainly in urban areas.

Low humidity and below normal temperatures expected Wednesday, then
temperatures rebound to near normal Thursday, and above normal late
in the week into the weekend. However, do not foresee heat issues at
this time.

Aviation 11z Monday through Friday
Vfr through the TAF period with high pressure south and east of
the terminals.

Winds will gradually back to the SW into this afternoon with
speeds increasing to around 10 kt. Afternoon sea breeze
development shifts winds to the south at coastal terminals, 10
to 15 kt. Winds will gradually diminish overnight.

There is a low chance for a shower or storm NW of nyc metro
terminals this afternoon evening.

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.
