Synopsis
A cold front will cross the area this evening, then push off
the coast overnight. High pressure builds into the area Wednesday
through Friday. A cold front approaches from the north Saturday.

Near term until 6 am Wednesday morning
As of 245 pm edt Tuesday...

ongoing convection continues this evening along and ahead of the
frontal boundary. Likely pops across the east early, lowering to chc
pops by late evening. Drier air from the west results in clearing
skies after midnight. Lows mid 60s west to lwr 70s along the coast.

Short term 6 am Wednesday morning through Friday
As of 245 pm edt Tuesday...

a warm drier airmass overspreads the area Wed thru Fri as high
pressure builds in from the nw. Expect mostly sunny warm days,
mstly clr mild nights. Highs Wed in the mid-upr 80s, upr 70s-
lwr 80s thurs and 80-85 fri. Lows in the 60s to nr 70 se.

Long term Friday night through Tuesday
As of 245 pm edt Monday...

models show a frontal boundary stalling across the mid atlantic
region with ripples of low pressure moving east along it through the
period. The two will be the focus for daily pcpn chcs. Will carry
chc pops each day, trying not to time any wave this far out in
time. The boundary will try to sag farther south Tuesday as high
pressure moves across the nern states. Pops a bit lower Tuesday.

Highs Sat in the low-mid 80s, mid 70s-mid 80s Sun mon, upr
70s-mid 80s tues. Lows in the 60s to near 70 se.

Aviation 20z Tuesday through Sunday
As of 200 pm edt Tuesday...

sct shwrs tstrm quickly developing out ahead of a cold front
this afternoon. Appears best chcs for these over the next few
hrs will be at ric sby then track towards the sern TAF sites
closer to sunset. Thus, will carry vcsh at ric sby with the
guidance showing a 2-3 hr window for a tstrm btwn 20z-23z,
then btwn 21z-00z across the SE with gusty SW winds 15-25 kts
out ahead of it. Kept CIGS vsbys in the MVFR range with this
forecast and will amend as necessary as the convection moves se.

The front pushes offshore arnd midnight with skies clrg and winds
shifting to the nnw.

Outlook: high pressure builds in for the mid week period with a
return to mainlyVFR conditions.

Marine
As of 400 pm edt Tuesday...

latest marine observations show that southwesterly flow continues
with 10-15 knots in the bay, increasing into the 15-20 knot range
for the coastal waters. The remnants of florence have been absorbed
by a larger synoptic trough which is approaching the area with an
associated cold front. SCA are still in effect for the northern
coastal water zones. Will drop the SCA for the mouth of the bay zone
at 6pm but have extended the SCA the northernmost zones until 10pm
to cover a slightly slower reduction in wave height across the
eastern edges of these zones.

Winds will begin to become northwesterly and gusty as the
aforementioned cold front traverses the area late this afternoon and
this evening. Cannot find a whole lot in the way of model support
for SCA conditions in the bay with the winds in the wake of the
front this evening overnight but a definite surge of increased winds
is evident. Winds are expected to top out just under SCA levels so
will not be issuing any additional hazards with this package. As the
northwesterly flow begins to subside after sunrise Wednesday we will
have a well deserved period of relatively quiet marine conditions.

We will have to watch the coastal zones once again for sca
conditions due to larger waves with northeasterly flow Wednesday
night and into Thursday but have held off on introducing any hazards
at this point due to low confidence. After this period high pressure
is expected to build into the region with generally lighter winds
and seas than we have seen of late.

Hydrology
As of 400 pm edt Tuesday...

river flood warnings have been issued updated for the meherrin
river at lawrenceville, the appomattox river at mattoax, the
rivanna river at palmyra, and the james river at bremo bluff
and cartersville.

Richmond westham and city locks are expected to reach into
minor flood stage later today but have held off on issuing
warnings for now as there is still time to monitor trends in
these locations.

coastal flood statement continues for elevated water levels
along the albemarle sound.
