Synopsis
Low pressure will track northward along the mid atlantic coast
this evening, then 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 through Sunday
As of 315 pm edt Saturday...

surface low, and accompanying shortwave trof, are lifting
northward through the region this afternoon. Back edge of
significant rainfall is about to clear the va nc border, and
will continue northward out of the region by mid evening. A
general 1 to 2 inch rain is accompanying this system, with a few
areas having received up to 3 inches of rain so far. After this
initial system clears the area, skies will remain cloudy to
mostly cloudy, with just isolated showers through early Sunday
morning.

Most short-range models continue to suggest another area of
showers isolated tstms will move across southern section of the
area late tonight Sunday morning, and have modeled pops to
account for this area. Slightly cooler air behind shortwave
moving through the area now will allow low temps to be in the
60s, with around 70 DELMARVA extreme SE va coastal NE nc.

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.

Short term Sunday night through Tuesday night
As of 320 pm edt Saturday...

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 20z Saturday through Thursday
As of 210 pm edt Saturday...

low pressure across NE nc continues to lift nnewd along the mid
atlc coast this afternoon. The low continues moving northward
into ERN pa and ny later this evening into Sun morning.

Rain showers have overspread the entire area, with MVFR ifr most
terminals. Conditions expected to improve to MVFR occasionalVFR
from south to north through 00z at kecg korf kphf, then
kric ksby in the 00z to 06z time frame.

Winds will be variable in direction at all terminals but kric,
where winds will be NW to W through 00z, then light and variable
overnight. At kecg korf kphf ksby, E SE winds will swing around
to the N NW from south to north, then gradually back around to
the south overnight.

Sunday through Tuesday will see unsettled 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 precipitation, and possibly
low stratus during the overnight 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...

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.
