Synopsis
Low pressure will track north into pa and western ny by Sunday
morning. A moist southerly flow, coupled with a low pressure
trough aloft over the southeastern u.S., will result in an
unsettled pattern through at least the middle of next week.

Near term until 6 am this morning
As of 1005 pm edt Saturday...

sfc lo pres INVOF central ches bay ATTM will continue to track n
overnight... Resulting in ra pulling away. Widespread 1-3 inches
of ra I 95 to the coast from this event... Likely locally higher
amounts interior ERN SE va. Area of convection slowing moving
through SW va NW nc expected to weaken heading E overnight.

Keeping chc pops far SRN va interior NE nc through the night.

Otherwise... Partly to mostly cloudy across the local area. Ese
winds gusty to 25-35 mph invof ERN shore a little while longer
then become ssw as the lo pres pulls away to the n. Windspeeds
likely to wind down later on. Lows in the m60s along-w of I 95
to u60s-around 70f e.

Short term 6 am this morning through Tuesday night
As of 320 pm edt Saturday...

deep southerly flow persists on Sunday, as upper low over the oh
vly gradually sinks southward into the southern appalachians by
sunset. As a result, more scattered, and mainly diurnal
shower TSTM activity expected. Under mostly cloudy skies, high
temps will make into the low to mid 80s, several degrees below
normal.

Aforementioned upper low will meander over the southeastern
u.S. Sunday night through Tuesday, allowing for continued deep
southerly flow, and continued chances for showers tstms across
the region. Rainfall Sunday night Monday expected to be across
the eastern half of the area. By Monday night Tuesday, atlantic
upper ridge begins to build westward, allowing main axis of
heaviest rainfall to shift into the central and western parts of
the area. Another 1-2 inches of rain is possible across the
area through Tuesday.

With deep moisture in place, skies will continue to be mostly
cloudy, with day time MAX temps still a few degrees below normal
both Monday and Tuesday. Highs both days mainly in the mid 80s.

Low temps Sunday night through Tuesday night mostly in the 70-75
degree range.

Long term Wednesday through Saturday
As of 320 pm edt Saturday...

decent model agreement continues through much of the extended period
as two well-established high pressure systems over the plains and
the atlantic keep rain chances sandwiched in between over our cwa.

Expect high-end chance to likely pops areawide through at least the
beginning of next weekend. Wednesday, likely pops stretch as far
east as the delmarva, especially during the afternoon evening.

Thursday morning, kept the best moisture and likely pops across the
northern half of the area... Before likely pops return for much of
our area Thursday afternoon evening. Friday and Saturday mornings
may be the "driest" portions of the extended, especially across the
western third of the cwa, but do expect daytime heating to spark
additional showers and thunderstorms each afternoon.

The euro and GFS begin to diverge on late Saturday and Sunday, with
the euro trying to weaken the atlantic ridge and thereby decreasing
the opportunity for rainfall. Not only does the 12z GFS disagree
with a weakening atlantic ridge, but it also brings another low
pressure system through the ohio valley... Sending additional energy
our way and increasing rain chances Sunday into the start of the
following week. While "all day" rain does not look to be the case,
each day this week will feature shower TSTM chances to some degree.

Keeping an umbrella and some golashes handy would not be such a bad
idea.

Temperatures will be in the mid to upper 80s wed-sat, with the
warmest day being Friday. Spots that receive rainfall will be an
average of 5-8+ degf cooler. Overnight lows in the low to mid 70s
will carry us through Sunday morning.

Aviation 06z Sunday through Thursday
As of 200 am edt Sunday...

low pressure that brought rain to much of the region during sat
was north of the cwa, and will lift into pa during this morning.

However, digging upper trough to our west resulting in weak sfc
low pressure over WRN nc sc was pushing sctd showers and
isolated tstms in our SW counties early this morning. Expecting
MVFR orVFR conditions thru 12-13z this morning at all TAF sites
except sby, where ifr CIGS will likely linger. MainlyVFR
conditions should then prevail at all TAF sites by 14-15z with
sse winds picking up and lasting into this evening. Today into
wed will see unsettled wx conditions at all terminals, with
periodic showers tstms, with most tstms in the diurnal 16z to
04z time frame. Overall flying conditions should be MVFRVFR,
with periodic ifr in pcpn, and possibly low stratus during the
overnight into early morning hours.

Marine
As of 330 pm edt Saturday...

latest sfc analysis shows 1002 mb low pressure developing along
a stalled frontal boundary over NE nc. The low will advance
north through the fa tonight, with strong onshore winds out
ahead of it. Maintained SCA headlines for this, while issuing
smw's for an hour or two of gale force gusts north of the low.

Winds drop off a bit behind the low but still will see 15-25 kt
sustained winds into the overnight hours, so have extended the
sca over the northern bay a bit. Expect up to 10 ft seas out 20
nm this evening, subsiding overnight. For sun, persistent sse
flow at 10-20kt develops which will last through the middle of
next week as low pressure settles over the tennessee valley and
high pressure locates over the WRN atlantic. Did extend the sca
over northern coastal waters where seas AOA 5 ft are expected to
continue through at least Sun night. Elsewhere, additional sca
flags are possible late Sun into early next week for wind and
seas.

Tides coastal flooding
As of 330 pm edt Saturday...

with tidal anomalies reaching 1.0-1.5ft above normal today and
tonight, issued coastal flood advisories for the va northern
neck and bay side of the lwr md eastern shore for this evening's
high tide cycle.

In addition, a high risk of rip currents is expected over
northern beaches through sun, with a moderate risk over southern
beaches.

As of 320 pm edt Saturday...

kdox radar is inoperable due to a failure of the motor. All
parts will not arrive until Tuesday july 24. Return to service
is unknown at this time.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
