Synopsis
High pressure will build overhead through tonight
before moving offshore Friday. A cold front will pass through
Saturday and high pressure will return for early next week.

Near term through tonight
Canadian high pressure will continue to build toward the region
through this afternoon before settling overhead tonight. A
northwest flow ahead of the high will cause chilly conditions
for this time of year, despite sunshine. MAX temps will be in
the mid to upper 50s for most locations.

Mainly clear skies, light winds and dry air will provide a good
setup for radiational cooling tonight as the high settles
overhead. Areas of frost are likely. Some sheltered valleys or
rural areas may drop below freezing as well, especially across
northern md and west of the blue ridge mountains. A freeze watch
remains in effect for these areas.

Short term Friday through Saturday night
Warmer Fri as high pressure moves offshore and winds turn
southerly. Clouds increase through the day with showers
developing in the evening as moisture gets drawn northward ahead
of an approaching cdfnt. Showers should linger through Sat until
frontal passage Sat evening. Rain showers could turn into snow
showers over the appalachians Sat night with trof passage.

Long term Sunday through Wednesday
Cool and dry autumnal weather will be featured for the second half
of the weekend and into next week.

Cool and blustery conditions are expected for Sunday with strong
northwest flow behind the departing low pressure system. Some
upslope snow showers are possible in the morning across the higher
terrain of the allegheny front. High pressure will then build into
the region for Sunday night and Monday bringing calmer conditions.

For both Sunday and Monday temperatures will average about 10-12
degrees below normals, with highs in the 50s and lows in the 30s.

Warm air advection will begin later Monday and Monday night as a
clipper system moves well north of the area Tuesday. This will
promote moderating temperatures with highs on Tuesday Wednesday
rebounding back into the 50s 60s with dry conditions continuing. A
dry cold front may move through Tuesday night Wednesday followed by
additional high pressure.

Aviation 14z Thursday through Monday
Gusts up to 20 kt today becoming light and variable tonight.

Showers expected Fri night and Sat with frontal passage late sat
or Sat evening. Gusts up to 20 kt expected sat.

Vfr is expected Sunday and Monday under building high pressure.

Gusty northwest winds are expected Sunday.

Marine
Sca conditions expected through today, then again late Fri or
fri night through Sun night. Gale conditions are possible late
sat into Sunday.

Sca conditions are probable Sunday and into Sunday night in gusty
northwest flow behind a departing low pressure system. Sub-sca
conditions return by Monday.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
