Synopsis
High pressure over the eastern united states will continue to
bring mainly warm and dry weather to the region through midweek,
while hurricane maria stays just off the east coast. A dry cold
front will move through the appalachians and mid atlantic
region on Thursday, with much cooler weather for the end of the
workweek into next weekend.

Near term through Tuesday
As of 245 pm edt Monday...

fair weather pattern continues with high pressure surface and
aloft yielding warm and dry conditions across the region. Expect
the veil of cirrus from maria off the coast to gradually wane
through tomorrow. This should allow for better cooling and more
coverage of fog west of the blue ridge overnight.

Fair and warm conditions continue for Tuesday with a northeasterly
breeze. Low level moisture will also be on the increase and help
generate some lower clouds, but do not anticipate enough instability
or orographic forcing to generate any precipitation so will continue
with a dry forecast
lows tonight will generally be in the low to mid 60s east of
the ridge with mid upper 50s to the west along with some cooler
readings in the valleys. Highs Tuesday will be in the mid upper
80s east, low mid 80s west.

Short term Tuesday night through Thursday night
As of 304 pm edt Monday...

really not much change this forecast as hurricane maria shifts north
and weakens well east of the outer banks, then heads northeast as
the upper trough and associate front move across by Thursday
morning. This front should be limited in moisture so not putting any
chance of showers. Will see some clouds and thats about it.

Wednesday looks to be the last day of summer like
temperatures dewpoints with highs in the upper 70s to lower 80s in
the mountains, to mid to upper 80s east. Lows Wednesday night still
above normal with upper 50s to lower 60s west, to lower to upper 60s
east.

Slightly cooler with less humidity Thursday with a little more
breeze out of the northwest. With partly to mostly sunny skies highs
will range from the mid to upper 70s west, to lower to mid 80s east.

Dewpoint temperature should drop into the lower to mid 50s most
places by mid-late afternoon.

Seasonably cool Thursday night with lows in the upper 40s to lower
50s west, to mid to upper 50s east.

Long term Friday through Monday
As of 203 pm edt Monday...

500 mb trough digs across the great lakes into our area Friday into
Saturday with high pressure starting to shift southward from the
great lakes into Sunday. Will be a dry cooler with temps close to or
below normal. Later Sunday into Monday the flow turns more northeast
as the high wedges southward. Should start to see clouds increasing
Monday especially as the flow turns more east off the ocean. At the
moment confidence in any showers is low, so keeping pops below 15
percent.

Aviation 19z Monday through Saturday
As of 245 pm edt Monday...

no change in quiet weather pattern with high pressure surface
and aloft. This will yield mainlyVFR tafs under some high
cirrus clouds, with the exception being late night valley
fog stratus west of the blue ridge producing a period of ifr
cigs vsbys at klwb and kbcb. Any fog stratus dissipates early
Monday morning withVFR through the end of the period.

Winds will generally be light this TAF period, though northeasterly
flow around maria off the east coast will amplify winds and
generate some low gusts mainly east of the blue ridge.

Extended aviation discussion...

overall persistence forecast through the first half of this week as
strong high pressure aloft slowly drifts across areas just to
our north. The upper high will gradually weaken and allow a
mainly dry cold front to move through the region late in the
week. Late night early morning fog can be expected through the
week as low-level moisture slowly increases in advance of the
front. For the most part,VFR conditions are expected to
continue through the week and into the weekend.

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.
