area forecast discussion

707 am edt Fri may 24 2019

Synopsis
High pressure builds in from the northwest today and then
passes over the region tonight, before sliding offshore
Saturday. This area of high pressure settles off the southeast
coast Sunday. A weak cold front drops through the region Sunday
night into memorial day.

Near term through tonight
As of 355 am edt Friday...

current WV imagery depicts a trough pushing through new
england. Surface low pressure is co-located with the trough,
with a weak cold front trailing to the SW into the NRN mid-
atlantic. The front remains N of the local area this morning,
with very mild temperatures ranging through the 70s early this
morning. The front will drop into the area today, and then push
s by tonight as high pressure builds in from the n. The airmass
behind the front will still be rather warm (and well mixed) with
high temperatures ranging from the low mid 80s over the ern
shore, to the upper 80s low 90s for much of the area with
downsloping deep layer NW flow. Drier behind the front today,
especially N where aftn dewpoints drop into the low mid 50s. The
24 00z NAM continues to bring some upper energy through the
area within the NW flow. However, a dry forecast has been
maintained given limited moisture. This impulse may manifest
itself in thicker CU for a period of time this aftn over
s-central va and interior NE nc. Mostly clear tonight with some
passing high clouds. Forecast low temperatures range from the
upper 50s to mid 60s.

Short term Saturday through Sunday
As of 355 am edt Friday...

24 00z numerical guidance continues to depict somewhat of a
reprieve from anomalously warm temperature Saturday as high
pressure passes across the region and off the mid-atlantic
coast, 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 (upper 60s immediate md atlantic coast) to the
low mid 80s farther inland. By Saturday evening, there is a
slight chc of showers tstms drifting off the higher terrain into
the piedmont.

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. This will result in
wsw low- level flow, 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.

Dewpoints Sunday aftn are expected to be in the mid 60s, so heat
indices are not a concern at this time. Lows Sunday morning
range from the mid 60s to around 70f.

Long term Sunday night 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 12z Friday through Tuesday
As of 705 am edt Friday...

a weakening cold front is approaching from the N as of 11z.

Residual mid and high clouds are dissipated early this morning.

The wind is SW 8-12kt ahead of the front, and will shift to nw
behind the front, with some gusts up to 20kt (primarily at
ric sby phf) later this morning into the aftn. High pressure
builds in from the N tonight, with the wind becoming light and
shifting to ne, and then E later tonight.

Weak high pressure prevails through the memorial day weekend
into Tuesday. There is a low probability of showers tstms
Sunday evening N of a line from ric to sby.

Marine
As of 415 am edt Friday...

no headlines in the short term today thru Sat night. Early this
morning, a cold front was laying just north of the area. Winds
were wsw mainly 5-15 kt over the waters, with waves 1-2 ft and
seas 2-4 ft. The cold front will drop acrs the waters this
morning, with winds turning to the NW or N mainly 10-15 kt
behind the front. High pressure will build down into and over
the area today into sat, then shift off the mid atlc and se
coast for Sat night thru sun. Winds will turn to the NE tonight,
then ese 5-15 kt sat, S 10-15 kt Sat night, and SW 5-15 kt sun.

Another cold front will drop acrs the area Sun night into mon
morning. Conditions should remain below SCA criteria into mon.

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.
