Synopsis
Mild high pressure dominates through Monday. A slow moving
frontal system will then approach the area Tuesday into Tuesday
night with a cold frontal passage by early Wednesday. The front
is slow to depart farther away with a wave of low pressure
developing along it and approaching the area mid into late next
week.

Near term until 6 pm this evening
Only minor updates needed this morning to reflect current
temperature and dew point trends. The cold front has pushed
offshore and high pressure is building in. NW flow prevails
through the day with perhaps some gusts in the upper teens late
this morning and aftn. With no sensible change in airmass and
mostly clear skies, highs will be similar to yesterday, mainly
upper 60s to lower 70s except mid 70s in the ny nj metro area.

Short term 6 pm this evening through 6 pm Saturday
Ridging continues to build into the region with weak WAA through
the short term providing dry and unseasonably warm conditions.

Even though optimal conditions will exist for radiational
cooling tonight, clear skies and light calm winds, the WAA will
limit its impact. 925mb temps at 12z this morning are progged
to be between 10c and 12c, and increase to 15-16c by 12z sat.

Sunny conditions expected on Sat with just few-sct cirrus. Highs
will remain above normal ranging in the mid to upper 70s except
on the twin forks of LI and SE coastal ct.

Long term Saturday night through Thursday
Warm weather continues through Monday as the jet stream remains
north of the region with upper level ridging. At the surface,
the dominant feature will be high pressure eventually moving
offshore and the resulting s-sw flow. Mainly clear sky
conditions are expected to continue through Sunday.

Clouds increase Monday into Monday night ahead of the next
frontal system. The next chance of rain showers arrives late
Monday night into Tuesday, when a deep upper level trough
approaches from the west.

The trough further deepens Tuesday along the eastern seaboard
with increasing meridional flow. This will give plentiful
moisture to a developing frontal system at the surface. The
frontal system will be approaching the region Tuesday into
Tuesday night with the region being in the warm sector to the
east of the low with strengthening southerly flow, thereby
increasing warm air advection. Precipitable water increases to
near 1.5 inches from the moisture advection. This is much above
normal for this time of year. According to okx sounding
climatology, it would be above the 90th percentile. Some
moderate to heavy rainfall will be possible.

The cold front moves across Wednesday morning, with a
substantial decrease in precipitable water thereafter to less
than 1 inch. The front slows down and is slow to depart away
from the region. The numerical forecast models show weak low
pressure development along it and the low approaching the region
mid into late next week, with rain shower chances continuing.

Temperatures are expected to be well above normal this weekend
through Tuesday with a gradual decline thereafter. Highs this
weekend through Tuesday are forecast to be well into the 70s
with lows trending to be well into the 50s and near 60 for some
locations along the coast and nyc. The highs are forecast to be
more in the 60s for next Wednesday and next Thursday.

Aviation 16z Friday through Tuesday
Vfr through the TAF period as high pressure builds in from the
west.

Good confidence in the wind forecast with the typical 20
degrees of variability either side of forecast through the day.

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.
