Synopsis
High pressure will build south of the area through early Sunday.

A weak backdoor cold front will stall over the area Sunday then
lift north as a warm front on Monday. A surface trof will move
across the area Tuesday. Weak high pressure builds over the area
during the second half of next week.

Near term through Saturday
Temperatures have dropped significantly this evening where skies
are clear and winds are light. Stratocumulus are seen over
eastern WV and western md where winds have picked up from the
west and are gusting over 25 mph. Temperatures in those areas
have jumped dramatically from the low 20s to near freezing in a
short period of time as seen at martinsburg. Temperatures will
bottom out in the upper teens east of the mtns in the next few
hrs but will likely rise overnight as winds strengthen and
mixing increases. There could be a few snow showers over the
mtns overnight as upslope flow increases potentially dropping as
much as half inch of snow. Any freezing fog this evening is
expected to dissipate by midnight as winds strengthen and mixing
increases. Overall, cold and breezy overnight.

Short term Saturday night through Sunday night
High pressure will remain to our south for Saturday and Saturday
night. A southwest flow around the high will usher in somewhat
milder conditions Saturday afternoon after a chilly start. Max
temps will be in the 40s for most areas.

High pressure will move offshore Sunday and a southerly flow
will usher in more moisture and somewhat milder conditions. Max
temps will be in the 40s for most areas with lower 50s in
central virginia. An upper-level disturbance will pass through
late Sunday and Sunday night. A few showers are possible... But
forcing from this system will be weak so any precipitation that
does fall will be light.

Long term Monday through Friday
Mild conditions expected during the long term period with dry
conditions on Monday as we sit between two boundaries and
southerly flow settles over our region. Some showers could
develop over higher elevations later on Monday and into Tuesday,
but still expecting mainly dry conditions over our cwa.

A cold front approaches Tuesday night increasing pops over our
area, but qpfs are not impressive. High pressure settles in
behind the front Wednesday into Friday with winds become
northwesterly... Then becoming southwesterly Thursday into
Friday as high pressure moves offshore.

Temperatures will be above normal in general with highs reaching
the 50s and 60s in most locations, except on Wednesday. Low
temperatures will be in the 30s and 40s, but colder on Wednesday
night.

Aviation 02z Saturday through Wednesday
Vfr conditions are expected tonight through Sunday morning. A
few showers are possible later Sunday and Sunday night along
with MVFR conditions... But confidence in precipitation is low at
this time.

Vfr conditions expected Monday into Wednesday. Maybe
sub-vfr conditions on Tuesday night as showers could move
through the terminals. Gusty winds expected on Wednesday, up
to 20 kt.

Marine
Low pressure will move out to sea tonight. A small craft
advisory is in effect for the maryland chesapeake bay south of
drum point and the lower tidal potomac river... Closer to the
gradient. High pressure will build to the south for tonight
through Saturday... But a tightening gradient will result in sca
conditions. The gradient will subside Saturday night and
Sunday. A weak disturbance will pass through Sunday night.

Winds are expected to stay below small craft advisory
threshold Monday into Tuesday. Winds could increase Tuesday
night into Wednesday behind a front, requiring a small craft
advisory over the waters.

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.
