Synopsis
A cold front crosses the region late this afternoon and evening.

High pressure returns Tuesday and Wednesday, then shifts off the
coast late in the week.

Near term until 6 am this morning
As of 820 pm edt Sunday...

have removed all pops for the overnight as summerlike wx
continues. Mainly skc W ssw winds 5-15 mph and lows from the
u60s-around 70f (potentially challenging daily record high mins
which are listed in the climate section).

Short term 6 am this morning through Wednesday
As of 355 pm edt Sunday...

Monday starts off mostly sunny, then becomes partly sunny from
nw to SE during the aftn. A fairly strong SW flow in the low
levels will make for another hot day (even near the coast) with
highs getting back into the lower 90s for much of the area. Sby
may see their 1st 90f day of the season and there should not be
any marine fog on the coast of the eastern shore where it is
expected to reach at least the low 80s. Mixed layer dew pts
suggest it will be a little less humid with dew pts falling
mostly into the lower-mid 60s (compared to the upper 60s around
70f we have seen today). Models show limited moisture with an
approaching cold front and forecast has only a 20-30% pop making
it to the NW zones by late aftn, likely holding off over se
va NE nc until the evening.

Best chance for shower tstms will be in the evening Mon along
the coast where sfc dew pts remain a little higher, but again
there is limited moisture (and lift) with this front so pops
will only be around 30% closer to the coast, 20% or less farther
inland where drier air pushes in quickly. Decreasing clouds and
turning cooler Mon night. Lows into the mid to upper 50s NW to
the mid 60s se.

While the front will have limited moisture, it will bring a
significantly cooler (and drier) airmass to the local area. Dew
pts likely drop into the 40s for most of the area on tue, with
mostly sunny skies and highs that will range from the mid 70s n
to around 80 f over the far south away from the water. Mostly
clr comfortable Tue night. Lows mostly ranging through the 50s,
though would not be surprised to see a few upper 40s in the
normally colder spots. Upper level ridge centered along the gulf
coast begins to build back N into the area on wed, but with sfc
high pressure lingering along the mid atlc coast, will still be
a comfortable seasonable late may day with highs into the lower
80s inland (and mostly in the mid 70s to near 80 f along the
coast).

Long term Wednesday night through Sunday
As of 355 pm edt Sunday...

an upper-level ridge centered over the SE us will dominate the
weather pattern for much of the extended forecast, bring hot and dry
conditions. Pops of 20-30% we added for Thursday for an slight
chance of a showers or thunderstorms as a disturbance moves SE into
the mid-atlantic. Highs will be near 90 inland and low mid 80s for
hampton roads and the eastern shore, with lows in the 60s.

Friday through Sunday will be the warmest days of the week. The
upper-level high will build northeast over the mid-atlantic and the
sfc flow will be out of nw. With the ridge and downsloping, highs
will may reach the mid 90s, especially in the richmond metro. Highs
will get to near 90 at the va and nc beaches and inland eastern
shore. Temperatures at night will not cool off much, lows will be
around 70.

Aviation 06z Monday through Friday
As of 130 am edt Monday...

vfr conditions expected through the forecast period as high pressure
remains off the carolina coast. A cold front crosses the area late
this aftrn and eve. Models show a narrow band of moisture with this
feature, but no more than a 2-3 hr pcpn window at any one TAF site.

Although confidence is low for addng thunder attm, went ahead and
indicated a svrl hr period of bkn CU starting at ric sby into the
erly eve, shifting toward the coast at phf orf ecg arnd 00z. Expect
a gusty SW wind 15-20 kts today ahead of the apprchg cold front.

Winds shift to the NW tonite behind the fropa.

Outlook...

vfr conditions continue through Wed as high pressure is slow to move
east. A NW flow pattern sets up by the end of the week. This may lead
to sct convection movinf nw-se across the area starting late Wed nite
and thurs.

Marine
As of 315 pm edt Sunday...

extended the marine dense fog advisory along the md coast through 7
pm per latest obs and beach cameras. A nearly stationary warm front
in the vicinity has been the cause for this fog. Expecting this
feature to lift NE and weaken by this evening, which should allow
the visibility to improve.

The pressure gradient between high pressure offshore and strong low
pressure over the great lakes will allow sse winds to increase a tad
late this afternoon evening. Generally expecting sustained winds
around 15 knots, with gusts approaching 20 knots in the bay for a
few hours before sunset, especially at elevated sensors. Winds
become south and southwest 10-15 knots by Monday morning as a
trailing trough cold front from parent low pressure over the
northeast approaches the local area. Ssw winds 10-15 knots in the
bay and 15-20 knots offshore will stretch into Monday evening before
the cold front crosses the waters from NW to SE early tues morning.

Models continue to show general agreement regarding a NW surge of 15-
20 knot winds behind the front Tuesday morning before decreasing to
10-15 knots by Tuesday afternoon. There may be a few hours of sca
winds in the bay. Seas remain in the 2-4 ft range through Tuesday
with 1-2 ft waves in the bay, except up to 3 ft tues morning.

Light ne-e winds expected on Wednesday before southerly flow briefly
returns Thursday. The next cold front passage Thursday night should
turn the winds back to the NE again on Friday.

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.
