Synopsis
High pressure will remain in control through Friday, drifting
south and east of the area Friday afternoon. A cold front
approaches Friday night. The cold front will sweep across the
area Saturday evening with brisk conditions into Sunday as high
pressure builds from the west. The high will shift off the mid
atlantic coast on Monday followed by a weak clipper like system
tracking through new england on Tuesday. High pressure then
returns for mid week.

Near term until 6 am Friday morning
Dropped low temps across the ERN outlying areas slightly based
on trends. Otherwise, the fcst is on track. Surface high
pressure builds toward the mid atlantic coast tonight. With the
high in the vicinity, winds will continue to diminish, and skies
will be nearly clear. There will be some weak warm advection
tonight at 900 to 850 mb. If winds decouple, and become light,
especially across the interior, temperatures will likely fall to
below freezing. So have kept the freeze warnings and frost
advisories in effect.

Short term 6 am Friday morning through Saturday
High pressure will move off the mid atlantic coast Friday and a
longwave trough with a shortwave rotating into the western
portion moves into the great lakes by the end of the day. One
shortwave moves across the area Friday night ahead of a more
potent wave and associated cold front approaching Saturday. Have
brought chance and slight chance probabilities into the region
with the shortwaves and cold front Friday night into Saturday.

Temperatures will be warm enough for the precipitation to be all
liquid.

Long term Saturday night through Thursday
Global models are in good agreement with the upper pattern
through early next week with fall like weather continuing in the
northeast. Long wave trough axis over the eastern great
lakes ohio valley Sat night will shift east of the new england
coast on Sun with zonal flow briefly developing Mon ahead of the
next shortwave tue. This is where solutions diverge in the
global models. The GFS is more amplified and more progressive
with building heights for the middle of next week while the
ecmwf is broader at h5 with another shortwave diving down from
central canada for thu.

At the sfc, a cold front will sweep across the area Sat eve
with low chances for rain continuing until the upper trough axis
swings through Sat night. Dry and unseasonably cool weather is
then forecast for the remainder of the period, although pops on
tue may increase in subsequent forecast packages if there is a
bit more moisture for a clipper like system to work with in
southern new england. Otherwise, brisk Sat night and Sun due to
the combination of CAA behind the front and a tightening
pressure gradient between strengthening low pres to the north
and a building high to the west.

Aviation 02z Friday through Tuesday
Vfr as high pressure builds to the south of the region into
Friday evening.

Vfr through the TAF period.

Wnw winds withs speeds falling below 10 kt throughout by mid-
late evening. Winds become light and variable tonight except at
kjfk and klga. Winds become wsw- SW at around 10-15kt by mid
Friday morning. Gusts to around 15-20kt are probable at all
terminals by around midday Friday. Gusts could abate outside of
nyc terminals by early Friday evening.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
