Synopsis
A weak cold front will drop across the region tonight into
memorial day before return back north of the area on Tuesday,
followed by a big warm up for the remainder of the week.

Near term until 6 am Monday morning
As of 315 pm edt Sunday...

latest wx analysis reveals sfc warm front now well north of the
local area into new england. Sfc cold front extends w-sw from w
ny eastern great lakes into the lower oh valley. Radar mosaic
showing increased convection diving sse across oh tn WV just
ahead of the front, with some isolated pulse convection which
developed to the east of the blue ridge now dropping across our
nw tier of counties. This initial round of convection is being
aided in part W lift from decaying MCS mcv which pushed across
the midwest earlier today.

Across the local area, widespread CU field developing as
convective temps are being met. Hrrr continues to show iso-sct
storm coverage over northern central zones between 19-23z 3p-7p
this evening over the northern third of the area and moist pre-
frontal airmass. Upper trough sliding across the northeast will
dampen the upper trough slightly this aftn tonight. This will
serve to force a second round of convection e-se across northern
neck md counties this evening as the front drops back south
across the areas. For that reason, have bumped to likely pop
tonight over md zones after 02z 10p, while keeping slight chc or
less across the southern tier of counties.

Temperatures already well into the upper 80s to low 90s
inland... Mid to upper 80s along the coast. Will be close for
meeting tying daily record high at ric. See climo section below
for details.

Multi-cellular storm mode still favored later this aftn, focused
mainly across the north given better moisture forcing.

Increasing downslope component to the winds will also serve to
lower areal coverage along and south of the 460 corridor. Have
40-50 pop for sct thunderstorms north, 20-30% pop central eastern
va for iso to widely sct thunderstorms central. Did include a
slight chc in nc counties after 6pm, mainly seabreeze aided
across NE nc coastal communities.

Spc convective slight risk remains oriented along and north of a
farmville-williamsburg-melfa line. Damaging wind gusts, frequent
lightning and brief heavy rainfall are the primary hazards... But
given potential for strong updrafts, a few reports of large
hail are also a possibility.

Short term 6 am Monday morning through Tuesday
As of 315 pm edt Sunday...

the front will drop farther south of the area during mon, under
a partly to mostly sunny sky. Not quite as warm in onshore
flow. Mainly just a slight to low end chance for showers tstms.

Highs on Mon will range thru the 80s to near 90, cooler near
the water.

The warm front will lift back north acrs the area Mon night into
tue morning. Upper ridging will remain anchored over the
southeast with sfc ridge setting up offshore. Remaining warm and
moderately humid. Partly sunny and a bit warmer once again.

Maintained a slight chc for mainly diurnally-driven thunderstorms
along the eastern third of the area on Tuesday.

Warmest day of the next week looks to be Wednesday.

Long term Tuesday night through Sunday
As of 315 pm edt Sunday...

big story in the extended will be continued very warm to hot
conditions across the region. An upper level ridge remains in
control at the start of the forecast period, amplifying across
the region on Wednesday. With w-sw to SW downsloping flow
during the day and 850mb temps in the 20-23c range, expect
temperatures to climb into the mid to upper 90s across much of
the area on Wednesday. Temperatures may even touch 100 degrees,
especially across far southern portions of the fa. Our one
saving grace is that decent mixing in low levels should keep
apparent temps near air temperatures. Thus, still don't expect
heat indices to be much of a factor. Warm and dry wed... But will
maintain slight chc pop for now for a stray shower or storm
given strong heating. But given strong downslope and no apparent
convective trigger, would expect coverage to be low at best.

Low temperatures on Wednesday night only drop into the low to
mid 70s.

By Thursday, the upper level ridge axis begins to break down push
east of the local area as a more potent shortwave develops and moves
across the midwest and great lakes. Thursday will likely be another
very hot day with temperatures making it up into the mid 90s across
much of the area. Shower and thunderstorm chances will be on the
increase as the shortwave and associated cold front approach and
cross the region late Thursday into early Friday. This boundary then
stalls lingers near to just south of the region into the weekend
bringing the potential for more unsettled conditions. Temperatures
cool down slightly Friday into the weekend, but are still expected
to remain above average as highs in the mid to upper 80s are
anticipated.

Aviation 20z Sunday through Friday
As of 1240 pm edt Sunday...

vfr conditions at the local area TAF sites this aftn will
persist into Mon morning. However, do anticipate some short-
lived MVFR conditions at sby and possibly ric after 22z 6p late
this evening into very early Mon morning, due to sctd tstms
(highest pops) moving thru that area. There is a lower chc of
showers tstms at phf orf, with the lowest chc at ecg during this
time period. SW winds become w-nw this aftn and likely onshore
(ne) at orf this aftn. Outside of tstms, winds will become
generally light and variable tonight, then NW or N by mon
morning.

Outlook:
mainlyVFR conditions expected Mon thru tue, with slight to sml
chc of a shower or tstm.

Marine
As of 320 pm edt Sunday...

mostly quiet across the marine area this afternoon with generally
light and variable winds (5-10 knots). Waves ~1 ft in the bay and
seas 2-3 ft offshore. There remains a chance for showers and storms
to drop east and southeast late this afternoon into the overnight
hours with strong winds being the main marine hazard.

Winds will become southeasterly this evening ~10 knots as compact
low pressure approaches from the nw. A weak cold front will follow
this low, allowing winds to become NW ~10 knots late tonight. Winds
swing around to the NE on Monday and then S 10-15 knots by Tuesday
afternoon as high pressure aloft remains anchored over northern gulf
coast. Waves in the bay will generally run 1-2 ft while seas
offshore will stay in the 2-4 ft range through mid week.
