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 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.

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 08z Monday through Friday
Vfr through the TAF period with high pressure south of the
region.

Winds will continue to become wnw-nw overnight. A brief period
of winds 10-15 kt with a few gusts around 20 kt remain possible,
but these should quickly diminish in the next hour or so with
winds becoming 10 kt or less thereafter.

Winds gradually back to the SW on Monday. Afternoon sea breeze
development backs winds to the south at coastal terminals, 10 to
15 kt. There is a lower probability of a sea breeze at kewr and
kteb with winds more likely staying sw-ssw.

Outlook for 06z Tuesday through Friday
Monday night Vfr. Slight chance of an eve shower NW of nyc
metros.

Tuesday MainlyVFR. Chance of a late day shower tstm.

Wednesday Vfr.

Thursday MainlyVFR. Chance of a late day shower TSTM mainly
north of the nyc metros and long island.

Friday MainlyVFR. Chance of a late day shower tstm.

Marine
With an overall weak pressure gradient remaining across the
region, winds and seas are expected to remain below small craft
advisory criteria (25kt winds, 5 ft seas) through Tuesday.

High pressure builds Tuesday night and passes south Wednesday. Sub
sca conditions expected during this mid week period.

Then, winds back around to the S SW as the high departs to the east
and a warm front passes. Winds increase, and SCA conditions are
possible later Thursday, and Thursday night. These persistent winds
continue Friday. Seas build Thursday and remain elevated Friday.

Hydrology
No hydrologic impacts expected through Thursday. There is
potential for localized flash flooding associated with summer
convection Friday through the weekend - mainly in urban areas.

River flooding is not anticipated.

Tides coastal flooding
Astronomical tides are still running high with potentially
another round of isolated minor coastal flooding for the south
shore back bays, which could be seen with the high tides
tonight (approximately between 10pm and 12am). The water levels
would only be expected to touch the minor benchmarks, again for
just a few gages in the south shore bays.

Equipment
Observations from kfrg (farmingdale, ny) are not available.

Observations from khpn (white plains ny) and khvn (new haven ct)
are being disseminated through backup methods. All is due to
an faa communication line outage. Return to service time is
unknown.

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.
