655 am edt Wed may 22 2019

Synopsis
High pressure settles immediately off the coast today into
tonight. This area of high pressure then shifts well off the
southeast coast Thursday into Thursday night as low pressure
passes north of the region.

Near term through tonight
As of 655 am edt Wednesday...

1025mb high pressure is centered near the qb on border early
this morning, and extends swd through the ERN great lakes and
into the mid-atlantic. Sunny and pleasant early this morning
with temperatures ranging from the upper 40s low 50s N and w, to
the low mid 50s over interior SE va NE nc, with readings in the
low 60s along the coastlines of ERN va NE nc. High pressure
will gradually shift toward a position immediately off the mid-
atlantic coast by this aftn. Mostly sunny and seasonal today,
with high temperatures ranging from the low mid 70s over the ern
shore (upper 60s immediate md atlantic coast) and coastal se
va NE nc, to the upper 70s around 80f well inland. A calm to
light NE wind this morning, will become SE this aftn. High
pressure remains near the coast tonight. Mostly clear much of
tonight, with an increase in mid and high clouds NW later
tonight. Low temperatures range from the mid 50s over the
interior ERN shore and interior SE va NE nc, to the upper
50s around 60f elsewhere.

Short term Thursday through Friday
As of 400 am edt Wednesday...

the mid upper level ridge axis will push offshore Thursday
morning as a shortwave trough tracks through ERN great lakes.

Meanwhile, the low-level flow will become sw, which will bring a
change in the airmass. High temperatures are forecast to reach
the mid 80s to around 90f across most of the area, with low 80s
for much of the ERN shore and coastal SE va NE nc, and upper 70s
at the immediate atlantic coast of the ERN shore. The
aforementioned shortwave trough will push across pa and nj
Thursday aftn and evening. This is expected to trigger
convection N of the region in a zone of 40-50kt 500mb flow and
35-45kt 700mb flow. Some tstms could move off the higher terrain
into the NW piedmont later Thursday aftn, and then tstms could
push into the NRN neck and md ERN shore by Thursday evening.

Forecast pops remain ~30% form the NW piedmont to the md ern
shore, bordered by 20% for much of the area, and less than 15%
far SRN va NE nc. SPC has continued a marginal risk for severe
tstms, and this is conditional on activity actually reaching the
local area.

The upper level ridge amplifies and builds back N Friday. Dry Friday
with high temperatures rising into the low 90s W of the bay, with
80s closer to the coast, after morning lows in the mid 60s to around
70f.

Long term Friday night through Tuesday

summerlike temperatures remaining above normal through the
extended forecast period as hi pres aloft remains centered ssw
of the fa INVOF central gulf states. Meanwhile... An anomalous
deep trough aloft will continue to largely remain out over the
wrn conus. Sfc warm front lifts N through the fa Fri night into
sat then W W flow aloft through the mid-atlantic ne
conus... That front will become hung up just N of the fa into
early next week. While isold convection possible both sat-sun
afternoons... Higher pops will be Mon afternoon as the trough
aloft sharpens through new england and a sfc cold front pushes
across the local area. Drying out cooling off tue.

Lows Fri night in the l-m60s N to the m-u60s se. Highs Sat in
the l-m80s E to the l90s w. Lows Sat night in the u60s-around
70f. Highs Sun in the 80s at the coast... L-m90s elsewhere. Lows

high pressure will build into and over the area during today,
then slides off the coast tonight into thu. Expect nne winds
5-15 kt thru this morning, then become E or SE 5-10 kt this aftn
into this evening. Winds become sse 5-15 kt tonight, then ssw
winds increase to 10-20 kt Thu into Thu night in advance of the
next cold front. Seas could build to 5 ft over the NRN three
coastal zns Thu evening into Thu night, but have held off on any

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.
