Synopsis
A cold front with limited moisture will move through the
forecast area today. High pressure and dry conditions will
dominate Wednesday and Thursday. Showers will return Friday and
Saturday as another low pressure system crosses the region.

Near term through tonight
The cold front will move through the area during the middle of
the day. There will be little moisture with h85 westerly flow.

Upper lift will be limited with broad upper troughing.

Observation trends and the high-resolution models suggest
scattered light showers in the convergent pattern along and
ahead of the front during the morning and early afternoon. We
followed the guidance consensus for the temperature forecast.

Further drying will occur behind the front tonight. We followed
the guidance consensus with lows mainly in the middle 30s north
to near 40 southeast. The pressure gradient may relax enough
for a period of calm wind toward sunrise. However, frost should
be limited because of marginal temperatures, a dry air mass, and
some wind during most of the night. Expect patchy frost with
coverage too low for a frost advisory in the central and south
section of the forecast area where the growing season has yet
to end because of the lack of a widespread freeze so far this
season.

Short term Wednesday through Thursday
Canadian high pressure will move across the great lakes and into the
northeast u.S. During this time period. Expect mostly clear skies
and slightly below normal temperatures for the holidays.

Long term Thursday night through Monday
Friday will be a continuation of dry weather, however it will be
cooler with chilly air from the mid atlantic states wedged into the
region. An upper level trough is forecast to swing across the
region Friday night into Saturday with showers likely. Sunday
appears to be a pleasant and dry day in between systems. A cold
front is expected to move through the southeast u.S. On Monday for
another chance of showers.

Aviation 11z Tuesday through Saturday
Expect mainlyVFR conditions through the 24-hour TAF period.

The cold front will move through the area during the middle of
the day. There will be little moisture with h85 westerly flow.

Upper lift will be limited with broad upper troughing.

Observation trends and the high-resolution models suggest
scattered light showers in the convergent pattern along and
ahead of the front during the morning and early afternoon.

There may be a period of MVFR conditions in these showers but
the chance was too low to include in the terminal forecasts at
this time. Further drying will occur behind the front tonight.

We followed the NAM and GFS mos for the wind forecast with
west wind veering to north during the period. Greatest speeds
will be around 10 knots today.

Extended aviation outlook... No significant impacts to aviation
expected through Thursday. Restrictions may develop Friday
and continue into Saturday associated with a low pressure
system in the region.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
