Synopsis
High pressure becomes centered off the mid atlantic coast through
Sunday night. Low pressure tracks from the gulf coast states
northeast up along the east coast late Monday through Wednesday.

Near term until 6 am Sunday morning
As of 18z Saturday...

sfc high moves off the coast with high level moisture returning in
the wnw flow aloft. Mstly clr this eve, bcmg pt cldy after midnite.

Lows upr 30s-mid 40s.

Short term 6 am Sunday morning through Tuesday
As of 18z Saturday...

sfc high becomes centered off the mid atlntc coast Sun and sun
night. Tsctns cont to show mid high moisture spilling east of the
mts. Skies bcmg mstly cldy north, pt sunny south. Highs in the 60s
except mid-upr 50s near the beaches. Drier air fliters south across
the DELMARVA Sun nite. Thus, mstly clr ne, pt cldy elsewhere. Lows
upr 30s-mid 40s.

Unsettled wx pattern shaping up next week as low pressure ejects
east from the nations mid section sun, into the tenn valley by late
mon. Models progg a potent SRN stream S W around the base of the
long wave trof Mon nite the move it NE to near the carolina coast
tue. This keeps the local area on the cooler side of this system
with a general rain expected to overspread the area.

Keeping most of Mon dry except for some low chc pops after 21z
across the swrn zones. Otw, bcmg cldy with highs in the 60s except
for mid-upr 50s at the beaches. Rain overspreads the fa Mon nite
except for the lwr md ERN shore where it may take until 12z Tue to
reach. Pops ramp up to cat-likely south of i64, chc pops to the
north. Lows Mon nite mid 40s NW to mid 50s se. Tue looks wet with
cat likely pops throughout the day. Enough lift gom moisture noted
for some areas of mdt rain along and west of i95. Highs Tue upr 50s
nw to mid 60s se.

Long term Tuesday night through Saturday
As of 350 pm edt Saturday...

after the main area of rain exits the region between 6-12z
Wednesday, we should see enough sunshine for temperatures to warm up
to around 70 Wed pm. 21 12z gfs ECMWF have showers lingering
throughout the day on wed, so kept pops between 50-60%. GFS even
hints at the possibility of a few thunderstorms Wed afternoon. Most
recent guidance has backed off on the rain Thursday-Friday am. Ecmwf
has the most qpf, and the best chance of rain looks to be over
southern eastern portions of the cwa. Thus, have lowered pops to
below 30%. Highs between 68-74 lows around 50 expected thu-fri.

A potent 500mb shortwave is forecast to track over the northeastern
us Friday into the weekend. This will set the stage for another
chance of rain late Friday-Saturday as well as another shot of
below average temperatures. Still quite a bit of uncertainty
regarding the strength timing of this storm system. Highs in the 60s
on Saturday with lows dropping into the 40s Sunday am.

Aviation 20z Saturday through Thursday
As of 145 pm edt Saturday...

vfr through the 18z TAF period. Winds today will remain light
from the N inland and from the E NE near the coast. Expect calm
winds tonight with a shift to the E SE at 5-10 kt on Sunday.

Skc for most locations through ~03z tonight, but some high
clouds increasing late tonight into Sunday.

Outlook:VFR conditions will continue sun, with high pressure
over the region. A disturbance approaches the region late Monday
and Tuesday bringing steady rain which will result in flight
restrictions. Restrictions will likely last through at least
12z Wednesday before conditions slowly improve during the day.

Marine
As of 300 pm edt Saturday...

high pressure will prevail over the region thru Sunday resulting in
benign marine conditions. Wind will remain primarily sea bay breeze
driven this aftn, then S SE 5-10kt tonight, before becoming N Sunday
morning then E 10kt by Sunday aftn as high pressure shifts toward
new england and low pressure moves into the deep south. High
pressure pushes off the SRN new england coast early next week as low
pressure moves off the southeast coast. This will result in
increasing onshore flow. An E wind is expected to reach 10-15kt by
Monday, and then 15-25kt by late Monday night Tuesday Tuesday night.

Onshore flow will result in seas building to 5-9ft Tuesday Tuesday
night, with 4-5ft waves in the mouth of the bay (2-4ft elsewhere in
the bay). Scas will eventually be needed for this time frame. Broad
low pressure crosses the region Wednesday with the wind becoming nw
in the wake of the low into thurs morning. SW flow 5-15kt then
develops for the end of next week.

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.
