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

Near term through Sunday
As of 950 pm edt Saturday...

latest msas has the warm front ivof the i95 corridor with the
surrounding radars showing the pulse convection weakening over
the past hr due to loss of htng as they move east. Impressive
lightning show ongoing to the north. Expect the current convection
to track ese across NRN zones over the next few hrs (but may briefly
pulse back up at times although not to severe limits).

Attention then turns to the next convective complex to the nw. High
res data has this activity sliding SE across the DELMARVA nrn neck
arnd 06z. Thus, will keep 20-30 pop going with the highest pop across
the north.

Otw, fair to pt cldy warm overnite. Lows in the upper 60s to near 70.

Pvs dscn:
on Sunday, the upper ridge is back over the area and the main
front is well to the north. This should lead to a hot and mostly
sunny day across the area. But will need to watch for developing
convective complexes to the northwest as a couple shortwave
troughs slide across the northern periphery of the ridge. This
may allow some additional storms into the area late Sunday
afternoon. Expect afternoon highs to jump back up into the low
to mid 90s for most areas.

Short term Sunday night through Tuesday
As of 415 pm edt Saturday...

with the upper level ridge getting knocked back south a little
because of a few shortwave troughs, more convection is possible
Sunday night into Monday as the frontal boundary returns back to
the south. The timing and development of the convective
complexes is difficult to peg at this time range, but with the
front getting drug southward, expect some convection to be
around the area with some showers hanging on through Monday
morning. But front will not remain south of the area long before
getting pushed back north of the area late Monday night into
Tuesday. As the front lifts back north it may still be focus for
more precipitation. But with the lack of a good kicker to
initial convection as the better dynamics are north of the area
from ohio into pa, the action along the warm front may be
limited. Behind the front on Tuesday, the heat begins to build
as ridge builds northward once again.

Temperatures will follow a similar pattern to the last few days
with readings slightly cooler on Monday after the front waffles
to the south with highs in the upper 80s to around 90. Then on
Tuesday readings jump up into the low to mid 90s once again. For
overnight lows, with the increase in the low level moisture and
clouds lingering around have kept temperatures in the upper 60s
to low 70s for most areas.

Long term Tuesday night through Saturday
As of 415 pm edt Saturday...

the story for the extended period will be the heat across the
region. An upper level ridge remains in control at the start of the
forecast period, amplifying across the region on Wednesday. With wsw
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 dewpoints look to generally stay in the lower
to mid 60s on Wednesday, so am not expecting heat indices to be much
of a factor. A stray shower or storm could also potentially limit
daytime highs on Wednesday, though with an amplifying ridge aloft
and building high pressure at the surface am expect any shower
potential to be very limited. 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 02z Sunday through Thursday
As of 715 pm edt Saturday...

generallyVFR conditions through the forecast period. Sct convection
ahead of an advancing warm front expected over the next svrl hrs this
eve into the erly morning hrs ivof sby. High res data showing that sby
has the best chc of seeing any tstms, so went ahead and added vcts
there btwn 03z-06z. Confidence to low to include thunder at any other
taf site attm. SE winds arnd 10 kts shift into the SW late tonight sun.

Outlook:
mainlyVFR conditions expected thru mon. Another convective complex may
track SE across the region and result in sct convection Sun aftrn eve.

Marine
As of 415 pm edt Saturday...

strong upper ridge in place across the southeast deep south this
afternoon with elongated surface high pressure moving slowly off the
mid atlantic coast. Winds generally from the east this afternoon at
5-15 knots with gusts 15-20 knots. Waves are around 2 ft in the bay
with seas 2-3 ft offshore.

Surface high will settle southward this afternoon evening allowing
winds to become southeasterly and increase a bit to 15-20 knots with
gusts 20-25 knots as the pressure gradient tightens between the high
and low pressure passing well the north of the local area.

Conditions are approaching SCA levels in the bay and lower james
river this afternoon and will increase slightly tonight, so went
ahead and hoisted SCA headlines from this afternoon into early
Sunday morning. Waves will build to 2-3 ft tonight with seas
generally 3-4 ft N and 2-4 ft s. Winds decrease and become SW then w
by Sunday afternoon. Thereafter, a series of weak fronts will impact
the area bringing changes in wind direction but little in the way of
enhanced winds. Upper ridge holds strong through mid week.
