Synopsis
High pressure anchored off the southeast coast for most of the
upcoming week. A weak frontal boundary approaches from the
northwest Monday and Tuesday.

Near term through tonight
As of 1150 am edt Sunday...

midday surface analysis shows high pressure off the southeast
coast. Meanwhile, to the west, still watching decaying MCS mcv
over the lower oh tn river valleys. Upper air analysis reveals
quasi-zonal flow aloft, as dampening upper trough over the ohio
valley slides e-ne this aftn.

Past few hrrr runs and the 12z cams are a bit less bullish on
convective chances... With capping inversion looking to stay in
place at least through 19-20z (3-4 pm edt). As such, have
scaled back pops a bit later into the day. Slight chance pops
remain confined mainly along and north of fvx-ric-sby line from
late aftn into the evening hours. Given the dampening weakening
vort MAX and warming mid-levels, did nudge pops down slightly
this evening as well, with the thinking that forcing will remain
maximized north of the local area. However, we have kept high
chance pop confined mainly over the northern neck north of
us360 and over the md eastern shore (held on to likely in
dorchester for now and will re-evaluate as hrrr gets better
handle on convection upstream).

Breezy south-southwest winds this aftn, W highs generally in
the upper 80s and low 90s with a few mid 80s possible near the
coast and along the eastern shore. A few lingering showers
possible late tonight in the piedmont. Otherwise, tonight will
average partly cloudy to mostly clear with low temperatures in
the upper 60s and low 70s.

Short term Monday through Wednesday night
As of 345 am edt Sunday...

a weak frontal boundary will sag slowly southward on Monday and
Tuesday and a gradual increase in shower storm coverage can be
expected as a series of kinks in the westerly flow aloft
traverse the region. Strong daytime heating and seasonally
robust low-level moisture will lead to the potential for a few
strong to severe storms on Monday, especially along and north of
the i-64 corridor closer to enhanced mid level westerly winds.

Spc has outlined a marginal risk for the whole CWA on Monday
with a slight risk area stretching generally from louisa ese to
the eastern shore where the potential for more organized
convection is greatest. The main threat will come in the form of
strong straight-line winds and locally heavy rainfall. Daytime
high temperatures will continue to be quite warm with low 90s
expected on Monday. Overnight low temps will be mild, in upper
60s and low 70s.

Tuesday will be much like Monday with the front inching closer
the area. Slightly increased shower and storms chances are
forecast with the potential for a few strong storms across the
region once again. Highs Tuesday will continue in the upper 80s
and low 90s. Unsettled weather pattern continues for Wednesday
with moist SW flow and strong daytime heating allowing for
scattered showers and storms. Highs in the upper 80s and low 90s
with overnight lows remaining in the upper 60s and low 70s.

Long term Thursday through Saturday
As of 330 pm edt Saturday...

flow aloft will remain mostly zonal throughout next week, with the
main flow just north of the area. However, several shortwaves aloft
will track from the central plains to the mid atlantic. As the
shortwaves move across the mountains, showers and isolated
thunderstorms will develop across the area. Highest pops (60-70%)
will be from Tuesday afternoon into Wednesday morning as a trough
moves through the area. A subtle NW flow will return between each
shortwave bring slightly drier air. Temperatures will be near
average for late june. Days with less rain will see highs
approaching 90 (near 80 for md beaches and low-mid 80s for va nc
beaches), while days with more rain coverage will see highs
remaining in the low 80s. Lows will remain near 70 throughout the
extended.

Aviation 18z Sunday through Friday
As of 640 am edt Sunday...

expecting mostlyVFR conditions through the 16.12z TAF period.

Southwesterly winds 10-15 knots will continue today with some
gusts to ~20 knots possible from mid morning through early
evening. Slight chance of showers and storms across the far
northern tier later this afternoon, generally north of ric but
may impact sby this evening. Not confident enough in placement
or coverage to include in the TAF at this point.

Outlook: sct diurnal convection psbl mainly north of a ric-sby
line thru most of the week.

Marine
As of 1245 pm Sunday...

surface high pressure is anchored off the southeast coast
early this afternoon, with low pressure and a frontal boundary
over the lower great lakes. A modest pressure gradient is being
created between these features, causing winds to remain
elevated on the ches bay and coastal waters north of parramore
island. For that reason, have expanded scas through 6 pm to
include all of the ches bay and also the lower james river for
sw winds 15-25 kt. Likewise for the northern coastal waters with
seas of 3-5 ft. We will see how winds seas behave by early
evening and assess whether a further extension of scas is
necessary.

High pressure remains anchored off the southeast coast Monday
through Thursday, as a stationary boundary remains to the nw. At
this time, sub-sca conditions are expected to prevail with a SW wind
averaging 10-15kt, and seas waves averaging 2-3ft 1-2ft. There is an
increasing chc of aftn evening showers tstms Monday through
Thursday, and there is a potential for nocturnal wind shifts to N nw
(especially across the NRN portion of the marine area) in the wake
of any organized convective systems.

river near sebrell. See flsakq for details.

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.
