Synopsis
Low pressure over the DELMARVA peninsula will lift to the
northeast and intensify near the gulf of maine today. Behind the
low, a cold front will cross the region today. Low pressure
departs over the weekend as high pressure builds in from the
west. The high moves off the southeast coast on Sunday. Low
pressure moves across the region Monday, and a cold front moves
through Monday night. High pressure then returns for most of the
new week.

Near term until 6 pm this evening
Low pressure over the DELMARVA peninsula will lift to the
northeast, and will be off the new jersey coast later this
morning. The low then moves into the gulf of maine by this
afternoon, and will intensify as an upper low with strong
shortwaves moves in from the west.

A cold front swings across the region by midday, and a tight
northwest pressure gradient develops in the afternoon.

West to northwest winds increase to 15 to 25 mph with gusts up
to 35 mph.

The bulk of the heavy rain has tapered off, but unsettled
conditions over the area will keep showers in the region this
morning. As the cold front passes through, additional showers
are possible. Going into this afternoon, with the passage of
several strong shortwaves, scattered showers will develop once
again.

Across the southern poconos, temperatures are cold enough to
support snow, and snow showers continue this morning before
mixing with rain showers later today as temperatures warm up a
bit. 1 to 2 inches of snow is possible in the higher elevations
of carbon and monroe counties through this morning.

With the heaviest of the rain being over, will go ahead and
cancel the flood watch. Any lingering flooding will subside, but
localized street flooding may redevelop with the passage of
additional showers.

Cannot rule out some convectively induced 40 to 45 mph wind
gusts this afternoon.

Highs today will range from the 30s in the far northern zones,
and otherwise in the 40s to low 50s.

Short term 6 pm this evening through 6 pm Saturday
Another cold front swings through the region this evening. High
pressure continues to build in from the west, but the low over
the canadian maritimes will not make much headway through the
overnight hours. As a result, can expect scattered showers, with
snow showers in the far northern zones, through the overnight.

Gusty northwest winds will continue, but should remain just
below wind advisory criteria, ranging from 20 to 30 mph with 30
to 40 mph gusts.

The low over the canadian maritimes finally lifts away late
Saturday, and high pressure continues to build in from the west.

Dry conditions on tap, but gusty northwest winds continue, until
finally subsiding late.

Sunny with highs in the 40s to low 50s, except in the 30s in the
southern poconos.

Long term Saturday night through Thursday
This extended forecast period will start out with a fairly strong
cold front passage on Monday, followed by canadian high pressure for
Tuesday through Thursday. On Monday a shortwv trof is forecast to
move east into the ohio valley with moisture spreading ahead of it
across the mid-atlantic region. Both the latest GFS and ecmwf
are showing precip spreading across the area on Monday and
continuing into Monday night in association with this feature
and with the frontal passage.

Temperatures ahead of the front on Monday should be warm enough for
rain everywhere, but fairly strong cold advection behind the front
may result in precip changing to snow from north to south Monday
night. No significant snow accumulation is expected at this time.

Temperatures on Tuesday and Wednesday look to be a bit below normal,
but may moderate to near normal again by Thursday.

Aviation 10z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... MVFR ifr conditions early this morning, eventually
lifting toVFR later this morning. Occasional MVFR conditions
this afternoon in scattered showers. NW winds 15-20 kt with
25-35 kt gusts.

Tonight... GenerallyVFR, but brief MVFR conditions possible in
scattered showers. Snow showers possible at krdg kabe. NW winds
15-20 kt with 25-35 kt gusts.

Outlook...

Saturday...VFR. NW winds 15-20 kt with 25-35 kt gusts.

Saturday night through Sunday night...VFR conditions with winds
generally 10 kt or less.

Monday and Monday night... MVFR countdowns possible in areas of
rain or snow showers. Winds around 10 kt shifting from SW to n
on Monday.

Tuesday...VFR conditions with NE winds around 10 kt.

Marine
A gale warning remains in effect for all waters, though there is
a lull in the gales that should last into daybreak. Northwest
winds increase to 20-30 kt with 35-45 kt gusts later today
through tonight.

Outlook...

Saturday... Northwesterly gales continue for much of this
period, but wind speeds should gradually drop off late Saturday
into Saturday night.

Sunday into Monday... Winds and seas are expected to be below
small craft advisory conditions.

Monday night and Tuesday... Northeasterly winds are likely to
increase starting Monday night and continuing into Tuesday. Seas
should subsequently increase as well.

Tides coastal flooding
The coastal flood advisory for the tidal delaware river above
the commodore barry bridge area has been allowed to expire now
that high tide has passed..

Guidance continues to indicate minor tidal flooding for the
morning high tide later this morning between 9 and 10 am for
middlesex, monmouth, and ocean counties. The low will continue
to slowly move away from the area through the morning hours, but
before it moves completely out of the area, easterly winds will
likely continue to push water into the northern new jersey
coastal line. Therefore we have issued a coastal flood advisory
for the next high tide for these counties.

Strong offshore flow will develop through the day Friday, which
will end the coastal flooding threat for subsequent high tides.

No flooding is not expected on the upper eastern shore of
chesapeake bay.

Phi watches warnings advisories
Pa... None.

Nj... Coastal flood advisory until 2 pm edt this afternoon for
njz012>014-020-026.

De... None.

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.
