Synopsis
High pressure becomes centered off the northeast coast tonight and
Thursday. Low pressure and associated frontal boundaries track
across the region Friday. High pressure builds over the area for the
weekend.

Near term /through tonight/
Current forecast on track with only minor changes to the grids.

Onshore flow around the high to the north will continue to pump
in mid level moisture as the days progresses. Result will be in
cloudy skies west and mstly cloudy east. Any light rain / shwr
activity expected to stay just west of the fa, mainly in the
favorable upslope areas. The clouds and onshore flow results in
a cooler day with highs ranging from the upr 40s-lwr 50s along
the coast, mid 50s-lwr 60s west of the bay.

Pvs dscn:
overrunning moisture pushes across the area late this evening
and overnight ahead of approaching upr level low. Will keep the
evening dry for most with light rain showers overspreading the
area by midnight far west... And after midnight east of i-95
midnight. Pops range from chc along the coast to likely across
the piedmont. Lows in the low- mid 40s.

Short term /Friday through Saturday/
Models remain in good agreement with handling of the upper level
low, which takes on a negative tilt as it lifts ene across the
oh valley on Friday. While the main low remains north of the
local area, NAM and to a lesser extent the ECMWF key into weak
meso low formation along the attendant frontal zone Friday
afternoon, with the triple point feature lifting e-ne across the
area Friday afternoon. This would present two distinct periods
of rainfall; the first a strongly forced, quick moving line of
showers producing rain Friday morning into early afternoon, with
a second line of convection possible for the mid-late afternoon
as the upper low and attendant surface cold front push across.

Pw's in the 1.25 to 1.50 inches and strong lift argue for rain
to fall heavily at times Friday morning. However, showers should
push through relatively quickly. Regarding the afternoon threat,
spc has now put the entire akq CWA in a marginal risk. Best
thunder chcs remain confined mainly across the southern half of
the area, with a slight chc across the north, where appreciable
clearing and destabilization is least likely. Strong deep layer
shear values would argue for at least a loosely organized
convective line with any t-storms that do fire, and reasonably
steep mid level lapse rates, lis <-4 deg c and CAPE maximized
across south central va and points south all argue for a narrow
window for strong to severe storms Friday afternoon across the
central/southern cwa, with the severe threat conditional upon
breaks in the overcast and resultant destabilization. In that
event, marginally severe hail, and damaging winds are the
primary hazards in any thunderstorms. Highs mainly in the 60s
to near 70 across the south, again dependant upon degree of
clearing after morning into midday rainfall.

Likely to categorical pops continue Friday evening with pops
tapering off after midnight as the low pulls offshore. Thunder chcs
will be limited to the evening with forcing and instability
waning quickly after sunset Fri night. Lows in the upr 40s-mid
50s.

Trailing upr level energy tracks across the eastern shore with
any showers tapering off before sunrise. Look for decreasing
clouds w/highs in the low- mid 60s eastern shore, mid 60s-lwr
70s west of the bay.

Long term /Saturday night through Wednesday/
Weak high pressure returns to the region Sat night/sun with
nw flow aloft. Mostly clear skies and cool temperatures
anticipated with lows in the 40s Sat night and highs in the 60s
sun (upper 50s atlantic beaches). High pressure slides offshore
sun night/mon as the next low pressure system deepens over the
arklatex region/lower mississippi valley. The low continues to
track NE into NRN oh/pa Mon night into tue... Dragging a cold
front through the mid atlantic region Tue aftn/evening. Increasing
cloudiness late Sun night into Mon with similar temps to sun. Lows
in the 40s Sun night, and highs in the 60s Mon (upper 50s atlantic
beaches). Sfc pressure gradient tightens substantially late mon
night into Tue ahead of the approaching cold front. S-w winds
gusting up to 25-30 mph will be possible. Widespread rainfall is
anticipated during this timeframe with very low thunderstorm
chances due to rain occurring primarily in the morning. Warmer
temperatures Mon night/tue as a warm front lifts north through the
region. Lows Mon night in the mid-upper 40s far NRN counties (i.E.

North of the warm front) and in the lower 50s elsewhere. Highs
tue in the 60s far NRN counties and in the lower 70s elsewhere.

Aviation /14z Thursday through Monday/
E-se flow allowing for some sct low stratus and patchy fog along
and ssw of phf/orf this morning. Expect the localized ifr/lifr
to mix out this morning. However, expect trend of lowering
cu/stratocu to continue today, albeit remaining inVFR range
through this evening. Strong low pressure over the southern
great plains will move northeast into the ohio valley later
Thursday, resulting in increasing mid to high clouds over the
mid atlantic region. Good model that ceilings will gradually
lower through the day from west to east with warm air advection
atop cool onshore flow at the surface. Mostly cloudy to overcast
conditions (ceiling in the 5 to 7 kft range agl) expected
through the day at ric, reaching SE terminals at korf/kecg by
mid to late morning.

Outlook... Low pressure will move from the ohio valley across
northern portions of the mid atlantic states to south of new
england by Saturday morning. Widespread rain develops late
tonight into Friday morning with a chance for thunderstorms
Friday afternoon and evening. Periods of MVFR/ifr will be
likely with visibility restrictions possible by Friday morning
and afternoon. Conditions improve quickly Saturday morning with
high pressure rebuilding back over the area for the weekend.

There will be a chance for showers western portions of the area
by late Monday as the next system develops over the mississippi
valley.

Marine
Latest sfc analysis shows high pres stretching down through the
mid atlc with a stalled frontal bndry over the SE states. Will
maintain the SCA over coastal wtrs today for seas up to 5 ft out
20 nm. Mainly 10-15 kt ne/e flow today, with the high sliding
offshore tonight and winds subsequently increasing late tonight
and especially into Fri as the next low pres systm and
associated cold front approach from the west. Marginal sca
conditions are psbl over the bay and more likely over the cstl
wtrs Fri with seas up to 6-7 ft, but will hold off on any
headlines for now with this being third period and some
headlines already in effect for today. The front crosses the
waters late Fri night/sat morning, with sub-sca winds expected
behind the front. Hi pres then builds in over the weekend.
