Synopsis
High pressure settles off the southeast coast through tonight
as low pressure passes north of the region. This area of low
pressure drags a weak cold front through the area late tonight.

High pressure builds in from the northwest Friday and then
passes over the region Saturday, and then shifts off the
southeast coast Sunday and memorial day.

Near term until 6 am Friday morning
As of 715 pm edt Thursday...

cancelled the watch at 7 pm as all the convection has weakened
and moved off the coast. In its wake, fair to pt cldy skies and
humid this eve. A cold front drops south across the region later
tonite. Latest data shows the front coming thru dry, but won't
rule out a stray shwr across the ERN shore as it does. Otw,
becoming mstly clear. Lows upper 60s to low 70s.

Short term 6 am Friday morning through Sunday night
As of 340 pm edt Thursday...

no major changes to forecast rationale for the near term period,
with weak high pressure building in from the north behind the
front for Friday. Still rather warm, but a bit drier across the
area, as high temperatures range from the low 80s over the ern
shore (upper 70s immediate atlantic coast), to the upper 80s low
90s in downsloping deep layer NW flow. Aftn dewpoints drop into
the low mid 50s. Could have some aftn CU stratocu in association
with a weak disturbance. However, warm dry soundings should
preclude any pcpn Fri Saturday.

Latest numerical guidance depicts somewhat of a reprieve from
the anomalous heat Saturday, as high pressure passes across the
region resulting in e-se low-level flow along the coast, and
se-s flow farther inland. Forecast highs Saturday range from the
low mid 70s E (cooler along the immediate atlantic coast of the
ern shore) to the low mid 80s farther inland, after morning
lows in the upper 50s to mid 60s. By Saturday evening, there is
a slight chc of showers tstms drifting off the higher terrain
into the piedmont.

Heat is back on for Sunday... Which has the potential to be the
hottest day of the spring thus far across our region. Surface
high pressure slides well off the southeast coast as low
pressure moves into the ERN great lakes. This will result in
w-sw low-level flow, which will help boost high temperatures
into the low mid 90s inland, with upper 80s over the ERN shore,
and even mid 80s at the immediate atlantic coast. Lows Sunday
morning range from the mid 60s to around 70f.

Long term Monday through Thursday
As of 230 pm edt Thursday...

summerlike temperatures remaining above normal through the extended
forecast period. An upper level anticyclone remains centered along
the gulf coast early next week before expanding eastward into the
western atlantic by midweek. Our region will be under the influence
of w-nw flow aloft thru Tuesday, then SW flow aloft wed-thu. A weak
frontal boundary crosses the area Sun night and Monday, but with
only isolated showers tstms possible Sun night. The boundary
lifts back NE quickly early tues with little if any forcing for
convection leftover by afternoon under the influence of ssw flow
at the sfc and rising h5 heights. Other than a late-day tstm
possibility near the piedmont trough, Wednesday looks dry also.

Wednesday also looks to be the hottest day next week as h85
temps rise to 20-22c with deep- layered SW flow ahead of the
next potential cold front by next Thursday. Lows through the
period in the 60s to low 70s, except some mid 70s possible wed
night. Highs Mon in the 80s over the lower ERN shore to the low
90s inland. Highs Tue from the mid-upr 80s over the ERN shore to
the low 90s inland. Forecast highs on Wed are in the upper 80s
to low 90s lower ERN shore to the low-mid 90s inland.

Aviation 00z Friday through Tuesday
As of 715 pm edt Thursday...

the line of tstms has cleared the ERN shore withVFR conditions
behind it. A cold front will cross the area north to south later
tonight, but the models show it coming through dry. Wind shift
to the n-nw at 10 kts or less fri.

Outlook: mainly dry conditions are expected through the memorial
day weekend, as weak high pressure prevails over the region.

There is a low probability of iso showers tstms Sunday evening
along and N of a line from ric-sby.

Marine
As of 300 pm edt Thursday...

sca is up from 7pm thurs to 7am Fri for our northern ocean zones.

Winds this afternoon will continue to be 15-20kt (gust up to 25 kt)
for the ches bay and northern atlantic zones (lasting into tonight
for ocean). Waves in the bay will be 2-3 ft and decreasing tonight.

For the atlantic zones off the eastern shore, seas will build into
this evening up to 5 ft (warranting sca). High pressure will move in
overnight and winds and seas will decrease. Friday afternoon there
will be a surge of wind NW 15-20 kt across the northern zones as a
low deepens off the southern new england coast.

A series of high pressures will be moving into the area through the
holiday weekend and into next weekend. There will be periods of
stronger southerly winds (around 15 kt) through the extend forecast.

However, it looks like winds and seas will stay below SCA criteria
through Monday.

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.
