Synopsis
Canadian high pressure builds over the mid atlantic region today
and Friday. The next cold front crosses the region during Saturday.

Near term until 6 pm this evening
As of 1000 am edt Thursday...

1035mb high pressure is centered over the midwest this morning
and is building across the mountains into the mid-atlantic with
+3 mb 3hr pressure rises observed over the area. There is still
a band of cirrus over NE nc, but this is thinning. Otherwise
sunny this morning with temperatures in the low mid 50s. The
center of the high will continue to build eastward today,
providing a sunny or mostly sunny sky and cool temps. Highs will
range from the mid to upper 50s n, to around 60 or lower 60s s.

Short term 6 pm this evening through Saturday night
As of 355 am edt Thursday...

tonight into Fri morning will be the coldest of the season so
far, as ~1030mb high pressure settles over the region. Forecast
lows are in the lower to mid 30s for the piedmont, interior
coastal plain, and interior md ERN shore. Some colder locations
potentially could drop to 32f given ideal radiational cooling
conditions and a dry airmass. Patchy frost has been maintained,
but frost could potentially be more widespread, especially for
the interior coastal plain and piedmont. Elsewhere, lows should
be in the upper 30s to lower 40s. High pressure will gradually
slide offshore by Fri aftn. Mostly sunny and milder with highs
ranging thru the 60s.

A cold front approaches from the NW Fri evening night, and
pushes across the region during sat. Pops are ~60-70% for
showers, with mainly light QPF between 0.15-0.35". Lows fri
night in the 50s, with highs on Sat ranging fm the mid 60s to
arnd 70. Pcpn will end fm NW to SE fm arnd midday Sat into early
sat evening.

Long term Sunday through Wednesday
As of 300 pm edt Wednesday...

forecast period begins with a rather progressive upper trough
dropping across the northeastern CONUS from the great lakes.

Associated surface cold front pushes offshore Sat night into
early Sunday morning. Sky quickly clears out Sat night, as
drier air moves in from the N nw. Lows will range from the low-
mid 40s NW to the low 50s in coastal SE va NE nc.

Expect cool, dry weather to prevail for the remainder of the
medium range period. Low-level CAA continues on Sunday, with
h85 temperatures will range from -1c to -4c Sunday afternoon),
with the surface high pressure to move overhead Sun night. This
results in high temperatures only in the mid-upper 50s on
Sunday. With the high (nearly) overhead, expect a cold night
across the area Sunday night, with mid-upper 30s inland low 40s
along the immediate coast, with temperatures possibly
approaching a freeze over inland spots early Monday morning.

Winds turn back to the south by Mon pm, allowing for a very
modest warm-up for early next week. Low pressure (sfc- aloft)
passes well to our north on Tue tue night. This will drag
another cold front through our area late tue- wed. However, this
will likely be a dry fropa. Highs in the upper 50s-low 60s on
mon rising into the mid 60s area-wide on tue, with morning lows
in the upper 30s-mid 40s on tue.

Aviation 14z Thursday through Monday
As of 200 am edt Thursday...

vfr conditions will prevail across all TAF sites today thru fri,
as high pressure builds over the area. Expect a N wind 10-15 kt
with gusts to around 20 kt at orf and ecg thru this morning.

Additionally, some sc (mainly 4-6kft) could develop near just
e-ne of phf orf in the form of bay streamer clouds during today.

Outlook: another cold front approaches from the NW Fri night
and moves through the area during sat. This will bring a high
chance of rain showers, along with the potential for lower
cigs vsbys. High pressure returns Sun into mon.

Marine
As of 355 am edt Thursday...

sca's remain in effect this morning as the CAA surge continues
behind the cold front. The surge subsides allowing winds to go below
sca levels this aftrn and tonight as the high builds over the area.

Waves 3-4 ft with seas 4-6 ft, both subsiding this aftrn.

The high shifts offshore late Fri and Fri night, allowing for the
return ssw to increase to btwn 10-20 kt (minimal sca's possible),
the next cold front crosses the waters Sat night into Sunday. Data
supports another strong CAA surge btwn 15-25 kt with gusts to 30 kts.

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.
