Synopsis
A frontal boundary stalls over the mid atlantic and southeast
states into Saturday, as high pressure builds eastward from the
great lakes into new england. The front will lift back north as
a warm front Saturday. A cold front will then cross the region
Sunday.

Near term through tonight
As of 340 am est Friday...

unsettled weather pattern will continue today with plentiful
moisture streaming into the area from the south and west. This
moisture will interact with a stalled frontal boundary to warrant
decent rain chances across the region, with the highest pops focused
across the southern half of the area today. QPF will range from
a few hundredths across the north to 0.25-0.50" across the
south. Widespread clouds and the front to our south will lead
to a cool day with mid 40s expected for high temperatures.

Highest pops overnight will remain across the south and
southwestern portions of the area before greater precip chances
begin to spread north and east into the early morning hours of
Saturday. High pressure to our north will continue to feed
cooler and drier air southward late tonight into Saturday but
overnight lows will be held in check by continued widespread
cloudiness with upper 30s to low 40s expected from north to
south.

Short term Saturday through Sunday night
As of 340 am est Friday...

Saturday will feature competing influences on local temperatures.

The aforementioned surface high to the north will get nudged
offshore in response to deepening low pressure across the central
plains moving northeastward into the midwest. An in-situ cad wedge
airmass will be entrenched across the piedmont as widespread clouds
and precip help to reinforce the near surface stable layer. At the
same time, a warm front will attempt to lift northward as southerly
flow ahead of approaching low pressure strengthens. There will
likely be a sharp gradient in temperatures across the region on
Saturday with upper 30s and low 40s across the far northwest ranging
to low to mid 50s across the southeast. Widespread precip is
expected over the area on Saturday with categorical pops expected as
deep layer moisture is lifted over the near surface cool stable
airmass. Focus for heavier rain will shift to the north Saturday
night as the warm front makes northward progress. Winds become
southerly in the wake of the front with steady rain transitioning to
showers after the front passes. A cold front will approach the
region on Sunday with westerly winds behind the boundary. Rain
chances will come to end as the front crosses the region. Storm total
precip will average around 1 inch with the highest totals
expected across the southwestern quadrant of the area where
1.25-1.50" is possible. Given the recent wet weather, and what
is expected to fall this weekend, we could certainly see some
river flooding issues into early next week.

Downsloping westerly winds and increasing late-february Sun angle
will allow temperatures to warm considerably on Sunday afternoon
with upper 60s and low 70s inland and low to mid 60s expected across
the eastern shore. Some guidance is showing mid and upper 70s for
Sunday, held off on going quite that high with this forecast package
but Sunday looks to be a very nice day after this prolonged period
of wet dreary weather. Decreasing dewpoints and cooler temperatures
will move in for Sunday night with mid 30s to low 40s expected for
overnight lows.

Long term Monday through Thursday
As of 345 pm est Thursday...

the flow aloft becomes more zonal across the CONUS early next week,
leading to less active wx across much of the country (including our
area). Drier (but still around average) Mon mon night as sfc high
pressure briefly settles into the region. Still dry seasonable on
tue as high pressure moves offshore. Highs on Mon will be in the mid-
upper 50s in most areas (except for low 50s on the ERN shore). Lows
mainly in the upper 20s-low 30s Mon night W highs rising to around
50 on the ERN shore mid 50s-around 60 elsewhere on tue. Lows tue
night range from the low 30s N NW to the around 40 se.

Models diverge in their solutions for mid-late next week. Latest
12z 21 ECMWF is forecasting high pressure to settle into the plains
(w sfc ridging extending to the NRN mid-atlantic region). The ecmwf
solution would lead to below average temps and mainly dry conditions
(perhaps a chc of light pcpn Wed night-thu). The GFS is much warmer,
as it tracks a weak area of low pressure N of the region wed-wed
night (bringing light rain), W slightly cooler air settling into
the region on thu. For now, went W a model blend from wed-thu and
kept slight chc pops in the forecast from wed-thu am (for -ra).

Forecast highs are in the 50s on wed, cooling to the mid-upper 40s
n low-mid 50s S by thu. Lows mainly in the 30s Wed Thu night.

Aviation 09z Friday through Tuesday
As of 1225 am est Friday...

another wave of moisture is streaming northeastward along a
stalled frontal boundary across the region. Patchy visibility
restrictions earlier tonight have improved as high and mid level
clouds stream into the area. CIGS areVFR MVFR and will lower
progressively through the course of the day. CIGS are forecast
to remain in the MVFR range through 23.00z before improving to
vfr. Slight visibility reductions to ~4sm are possible in areas
of precip Friday afternoon. Winds will generally be light and
variable overnight but will become northeasterly into the
morning hours. Generally below 10 knots for inland sites with
ecg and orf having the greatest chance to see sustained winds
above 10 knots.

Outlook... MVFR ifr conditions in rain, drizzle and fog
continue Fri night and Sat as a series of impulses move along
the stalled frontal bndry. The bndry moves north as a warm front
late Sat keeping unsettled wx conditions into Sun morning. A
cold front moves across the area sun.

Marine
As of 350 am est Friday...

still fairly benign over the marine area with seas of only 2-3
ft and bay waves 1-2 ft. Will see some increase in winds later
this morning as sfc high pressure to the N sags south into the
area. Have speeds increasing to 10~15 kt, and 15-20 kt for the
southern coastal waters. With nne flow will have to watch to see
if seas respond and try to build to 5 ft S of CAPE charles
light, but current thinking is that the stronger winds will be
short-lived. The sfc high builds into the waters this
aftn evening so winds should diminish to only 5-10 kt from the
ne. On sat, the sfc high gradually retreats to the ne, as the
frontal boundary to the south begins to lift back N as a warm
front Sat night. Winds will veer to the SE Sat night then to the
sw and increase on Sun as a stronger cold front approaches from
the west. SCA conditions appear likely for all zones Sun and
sun night (sw winds shifting to the W sustained to 20 kt with
gusts to around 30 kt). A period of gales will be possible over
the northern coastal waters Sun night into Monday. The offshore
flow will keep seas from building much above 5-6 ft. Diminishing
winds seas later Mon and Mon night.

Hydrology
Noting richmond westham rising faster than anticipated this eve. Latest
update has the level of rise slowing then leveling off overnight but not
reaching flood stage until Fri eve. Held off on a warning ATTM given the
updated forecast. Other main stem rivers will see rises given the forecasted
rainfall over the next few days. Went ahead and added a blurb about this in
the hwo.
