Synopsis
A cold front approaches from the west today and passes through
early Wednesday followed by high pressure. A warm front moves
north Saturday followed by a cold front Saturday night. High
pressure builds to the west Sunday and Monday.

Near term until 6 pm this evening
Sunny and "mild" - at least relatively so.

Some thin cirrus - but "basically" sunny. Temps top out at or
near 60 most areas with a breezy ssw flow. Last 60 degree day of
the year?? Probably not.

Short term 6 pm this evening through 6 pm Wednesday
Rather impressive shortwave over the gulf of mexico with
convection firing in the right rear quadrant of 100 kt jet
streak. This convection lifts rapidly across fl to off the
carolina coast this evening. Jet then strengthens to 120 kt
ahead of the sharpening of the northern stream shortwave.

Nwp, including the gefs, SREF and hrefv2 (replaced spc's sseo)
ensembles all support rain moving into nyc long island and s.

Ct before sunrise. Have raise pops significantly from previous
forecast due the observed dynamics and the consensus of the
latest nwp.

Does not look like a very nice morning rush. Rain may come down
hard for around 7-8 am.

Rain will move east of the region by noon though as colder air
rushes in Wednesday afternoon with gusty NW winds and clearing
skies.

Long term Wednesday night through Monday
Long range models are in good agreement through fri, with
noticeable differences starting Sat as a shortwave approaching
from the northern rockies interacts with a canadian vortex near
hudson bay. This is leading to timing and amplitude differences
with the 00z ec now developing a cutoff low over new england sun
night. GFS remains open.

As such, no big changes to the previous forecast through the
end of the week, but have cut back on the extent of pops
associated with the warm FROPA on Sat as models have trended
slower and drier. Southern stream shortwave and developing sfc
low passes well S and E of the area Sat sat night as a cold
front moves through the local area. Not much moisture for the
front to work with have kept the forecast dry Sat night.

Since the upper pattern is a bit uncertain next weekend, this
offshore low will need to be watched. If the full latitude
trough amplifies more, the low would shift to the west and could
result in potential impacts.

A secondary cold front with a reinforcing shot of cold air
could bring a few showers to the area on Sun with gusty winds
developing in its wake. Vigorous shortwave in the GFS which ec
is weaker. Schc to low chc pops with this feature. Soundings
mostly support rain at this time, although could get some wet
snowflakes Sun morning N and W of nyc.

Daytime temperatures are expected to be below normal through
the period, except on Sat in the warm sector. Overnight lows
also below normal except Fri Sat nights where they'll be near
normal.

Aviation 12z Tuesday through Saturday
High pressure slides further of the mid-atlantic coast today. A cold
front approaches from the west tonight.

Vfr through at least midnight. MVFR then develops at ct long
island city terminals from E to w. Low chance at ifr ct long
island terminals and very low chance city terminals. Should
stayVFR at kswf through the TAF period.

Sw winds increase to around 10-15g20-25kt by mid-late morning.

Winds diminish late this afternoon early this evening. With
gusts abating during the evening. Winds become light and
variable outside of kjfk klga overnight.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
