Synopsis
A weak low pressure troughs will form over land Monday and move
offshore Monday night. A cold front crosses the region Tuesday
afternoon with high pressure building to the south of the region
for Wednesday. A warm front crosses the region late Thursday
followed by warm, humid and unsettled weather on Friday though
the weekend.

Near term until 6 am Monday morning
The fcst is on track with no major changes made.

Latest satellite imagery shows upper low just north of lake
ontario with another shortwave that has kicked off more
scattered showers from bgm down to central pa. Extrapolation of
this suggests arrival is not until just after midnight. The
latest hrrr suggest new activity feeding off the mid level
instability and latest goes-16 visible data support at least
some of this with moderate CU seen over eastern pa. Sounding
shows all instability is below the -20 c level - so only
expecting showers. Have gone with a 20 to 30 pop for now.

Overnight lows fall into the 50s and 60s.

Short term 6 am Monday morning through Monday night
Another weak surface trough develops over the area Monday.

Aloft, heights fall to the west of the area as next shortwave
moves across the great lakes region.

Plenty of sunshine Monday morning, gives way to a some
afternoon clouds especially north and west of nyc. A few
isolated showers will again be possible across the interior.

Dry conditions are expected Monday night.

Temperatures on Monday will climb into the 70s and lower 80s.

Monday night, lows fall into the 50s and 60s.

Long term Tuesday through Sunday
Looks fairly dry with comfortable humidity and slightly below normal
temperatures through mid week. A warm front approaches on Thursday
as low pressure passes across southern canada. In its wake, a cold
front sags south into ny state on Friday. The front becomes
stationary near the region into the weekend - which appears will be
"unsettled."
upper trough axis approaches Tuesday, passing Tuesday night. Perhaps
a tad more instability Tuesday and trof pseudo cold FROPA triggers a
showers and perhaps a TS (instability is limited with dry mid
levels).

Wednesday is dry and then warm advection starts in on Thursday.

Frontal boundary in the region, or just north, on Friday and have
pops in for tsra. Looks to remain unsettled through the holiday
weekend at this time. Li's as low as -5 c with long narrow cape's
and pwat's over 2 inches in a unidirectional flow supports
potential for flash flooding - mainly in urban areas.

Temps come back to near seasonable on Thursday and then go above
Friday into the weekend. No heat issues foreseen though.

Aviation 03z Monday through Friday
High pressure will remain S of the region thru the TAF period.

Sw winds become light wnw overnight, and SW close to 10 kt by
mon afternoon, with coastal sea breeze development by 15z-16z.

An isold shra is possible thru 6z. Outside of any shwrs,VFR
thru the TAF period.

Outlook for 00z Tuesday through Friday
Monday night MainlyVFR. Coastal sea breezes. Slight chance
of an eve shower TSTM 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 at kswf.

Marine
Winds and seas will remain below small craft levels through
Monday night. Ocean seas will likely build to SCA criteria late
Thursday and continue as such into 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 running high, especially during the
nighttime high tide cycles.

Main area to watch would be across the nassau south shore bays,
where water levels should briefly touch or barely exceed minor
thresholds this evening. The times of high tide are from 9-11pm.

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.
