336 pm est Mon dec 10 2018

Synopsis
Surface high pressure will make a brief appearance across the region
tonight. At the same time, a weak surface low will track across the
great lakes. The low will move into new england, bringing a cold
front through the area Tuesday night and Wednesday. High pressure
will build into the northeast Wednesday night and Thursday. A strong
surface low will develop across the deep south late this week and
move rapidly northeast near or through the area this weekend.

Near term until 6 am Tuesday morning
A ridge of high pressure will settle across the area tonight. Skies
will be mostly clear with perhaps some ci across the DELMARVA and
srn nj areas. Winds will become light, favoring a nrly direction.

Temperatures will be cold, with teens across the far north and
low mid 20s elsewhere. Our temps are below much of the stat guidance
offered.

Short term 6 am Tuesday morning through 6 pm Tuesday
A continuation of fair weather for Tuesday. The ridge will inch off
the coast during the afternoon while weak low pressure crosses the
great lakes. Skies will be mostly sunny and winds will be light.

High temperatures will be like todays with 30s across the north and
mostly low mid 40s elsewhere.

Long term Tuesday night through Monday
Synoptic overview... The period starts with weak surface low
pressure moving into new england and an associated cold front
tracking through our forecast area. High pressure at the surface
and aloft will build on Wednesday. A mid-level low will cut
into the ridge, as it moves across the great lakes, Wednesday
night and Thursday. Pressure falls can be expected on Friday a
low develops across the deep south and starts to work our way.

The low will ride up the interior portions of the east coast
Friday night through Sunday.

Temperatures... Normals for philadelphia are in the mid 40s and lower
30s. Below normal temperatures are expected Tuesday night through
Thursday. Near to above normal temperatures are then expected
Thursday night through Monday.

Precipitation... At least some of the region have three shots of
precipitation through the forecast period with chances increasing
during each event.

A weak cold front is expected to track across the region Tuesday
night. At the moment, any precipitation associated with the front
will be confined to the southern poconos and northwest nj and should
be light. Better chances exist to the north and west of our cwa. If
any precipitation does make it into our area, it will be cold enough
for snow. But the latest gfs, cmc, and ECMWF keep any measurable
just to our north.

The 2nd shot of precipitation is slated to occur on Thursday as a
mid-level low cuts across the northern mid-atlantic or southern new
england states. Once again precipitation will be light. Temperature
profiles suggest some diurnal snow across the i95 corridor and
coastal plain, and all snow across the far northwest.

The 3rd shot will be the wettest. It's a southern stream storm with
connections to the gulf of mexico. Precipitation will start sometime
on Friday (looks like the 2nd half attm) and persist into Saturday
night. While track details will work itself out, all point to inland
track with all rain, except if it were to start Friday morning. With
its deep south connections, a period of moderate to heavy rain is
expected. Confidence is high and pops will remain in the likely
category.

Winds... Coastal communities could see some west winds in the 10 to
20 mph range Tuesday night. The next shot of any wind will be some
gusty SE winds on Saturday and Saturday night, especially near the
coast. Otherwise, winds should be 10 mph or less.

Impacts... Potential hydrologic impacts possible late Friday into the
weekend due to moderate-heavy rain.

Aviation 21z Monday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Tonight...VFR with mostly skc. Light north winds or calm air
expected.

Tuesday...VFR expected. A few ci clouds or perhaps CU during the
afternoon. Light NW winds during the morning then turning SW late.

Outlook...

Tuesday night through Wednesday... MainlyVFR with light west winds
Tuesday night, becoming northwest and increasing to 7 to 15 kts on
Wednesday (with higher gusts possible).

Wednesday night and Thursday... MainlyVFR, but cannot rule out a
period of sub-vfr Thursday. Winds becoming east generally near or
below 10 kts.

Thursday night and Friday... Deteriorating conditions expected
through the period, with sub-vfr conditions likely by Friday
afternoon. Increasing chances of rain. Southeast winds increasing to
7 to 15 kts on Friday, with higher gusts possible, especially near
the coast.

Friday night and Saturday... Sub-vfr expected in rain. Mainly se
winds with gusts 15 to 30 kts possible late Saturday, especially
near the coast.

Marine
Marine... Winds and seas remain up across the southern waters with a
continuation of the decent pressure gradient associated with the far
offshore storm. The seas were 10 ft at 44009 earlier, but have
lessened since then. We expect the SCA conditions to continue
tonight and therefore the flags will remain as is. The ending time
was extended into Tue for the southern waters with seas lowering at
a slower rate. Fair weather tonight and Tuesday.

Outlook...

Tuesday night... A brief period of advisory-level winds is possible
as a cold front approaches and northwest flow becomes established.

Wednesday through Thursday night... Sub-advisory winds seas expected.

Friday... Southeast winds will increase through the day and may
approach advisory levels late. Increasing chances for rain.

Friday night and Saturday... SCA conditions likely with gales
possible late Saturday. Mainly southeast winds.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

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.
