Synopsis
High pressure dominates thru Sunday. A weak cold front drops
across the area Sunday night into memorial day.

Near term until 6 am Saturday morning
As of 720 pm edt Friday...

latest msas has a weak dry frontal bndry drifting south from srn
va with high pressure located over the gt lakes and across the
deep south. Fair to pt cldy dry overnight. Lows upr 50s-mid 60s.

Short term 6 am Saturday morning through Monday
As of 205 pm edt Friday...

short-lived reprieve from anomalously warm temperatures for
Saturday, as high pressure passes across the region and off the
mid-atlantic coast, with low-level flow veering around to the
e-se se-s flow farther inland . Forecast highs Saturday range
from the low mid 70s E (upper 60s immediate md atlantic coast)
to the low mid 80s farther inland. Dry Saturday aftn, with
soundings appearing well-capped for much of Saturday over the
area. By Saturday evening, there is a slight chc of
showers tstms drifting off the higher terrain into the piedmont,
so will include a slight chc pop for an isolated shower between
22z 6p and 04z midnight west of i-95.

Sunday will likely be the hottest day of the spring thus far.

Surface high pressure slides well off the southeast coast, as
low pressure moves into the ERN great lakes. Meanwhile, the
se upper ridge will slide into position across the southeast
coast up into the mid-atlantic region. This will result in w-sw
low- level flow locking, which will help boost high temperatures
into the low mid 90s inland, with upper 80s low 90s over the
ern shore, and even mid 80s at the immediate atlantic coast.

Low-levels should remain well mixed, and therefore while a hot
day is expected, heat indices are expected to remain near the
air temperature. Overnight low temperatures won't provide much
relief, with early morning lows Sunday morning range from the
mid 60s to around 70f, and in the upper 60s to mid 70s Monday
morning.

Another weak front associated with low pressure moving by well
to our north will drop across the area Sun night. However, once
again, pw values would indicate areal coverage to be quite low.

Will maintain a slight to low end chance pop over northern tier
of counties for some evening late night showers Sun night.

Modestly "cooler" and a little less humid for memorial day on
Monday, as winds briefly veer around to the nne. Remaining very
warm and mainly dry. Highs in the 80s to low 90s inland.

Long term Monday night through Friday
As of 315 pm edt Friday...

summerlike temperatures remaining above normal through at least
next Thursday. An upper level anticyclone remains centered
along the gulf coast Monday night before becoming centered over
fl as upper ridging amplifies over the western atlantic by
midweek. A potent shortwave then tracks through the NRN great
lakes late next week as an upper low remains centered INVOF the
hudson bay. Our region will be under the influence of w-nw flow
aloft thru Tuesday, then SW flow aloft wed-thu. Staying dry
through at least Wed night as we will be under the influence of
ssw flow at the sfc and rising h5 heights. Wednesday also looks
to be the hottest day next week as h85 temps rise to 20-22c with
deep-layered SW flow ahead of an approaching cold front. The
cold front is progged to cross the region from late thu-thu
night as the aforementioned upper shortwave tracks through the
nrn great lakes. Isolated-scattered showers tstms will accompany
the FROPA thu-thu night. Have added a slight chc-chc of
showers tstms from 12z thu-12z Fri to account for this (pops no
higher than 30% for now).

Lows through the period in the 60s to low 70s, except some mid 70s
possible Wed night. Highs Tue from the mid-upper 80s over the
ern shore to the low-mid 90s inland. Forecast highs on Wed are
in the upper 80s to low 90s on the ERN shore to the mid 90s
inland. Highs still in the upper 80s on the ERN shore to the
low-mid 90s inland on thu. Slightly cooler on Fri with highs in
the 80s area-wide.

Aviation 01z Saturday through Wednesday
As of 720 pm edt Friday...

vfr conditions thru the forecast period as high pressure dominates.

Nne wind AOB 10 kts shift to the ese sat.

Outlook:
vfr thru the holiday weekend. There is a low prob of convection west
of the terminals Sat night and N of a line from ric-sby Sunday night.

Marine
As of 340 pm edt Friday...

departing upper trough over new england is giving way to building
heights aloft as strong upper ridging over the southeast expands
northeastward. A weak cold front moved south through the area this
morning with generally north and northwest winds 10-15 knots, a few
gusts to ~20 knots at elevated sites this afternoon. Waves are
generally 1-2 ft while seas are 2-3 ft.

Winds become east tonight and then southeast 10-15 knots by Saturday
afternoon as high pressure centered to our north moves offshore. Sse
winds increase to 10-20 knots Saturday evening as the pressure
gradient temporarily steepens. Winds become southwest and eventually
westerly with time into Sunday afternoon as high pressure sinks
southward off the carolina coast. A weak front is forecast to drop
southeast through the region, turning winds to the nw-n Sunday
night. Strong ridge aloft will be in control through at least the
first half of next week. Waves will generally be in the 1-2 ft range
with seas 2-4 ft.

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.
