Synopsis
A cold front approaches from the northwest this memorial day
and stalls north of the region Tuesday into Wednesday.

Meanwhile, weak low pressure tracks across north carolina
tonight and off the outer banks Tuesday.

Near term until 6 pm this evening
The current surface analysis places weak low pressure off the
delmarva coast, with a weak surface ridge axis across the
piedmont, and a slow moving cold front over the ohio valley.

Stratus fog is widespread across the area early this morning,
with some locally dense fog across the piedmont and portions of
ne nc. Stratus fog will gradually dissipate from sw-ne through
the morning as drier air arrives from the wsw resulting in
partly to mostly sunny conditions by aftn. Temperatures early
this morning range from the mid 60s to around 70 across most of
the area with low 60s for the md ERN shore. Forecast highs today
are mainly in the mid upper 80s for central SRN SE va and ne
nc. Temperatures will be lower over the ERN shore where stratus
will be slower to erode, with highs generally in the mid 70s to
near 80, and perhaps only around 70 for the md beaches. There is
little support for showers tstms today, with only a slight chc
of sea bay-breeze convection over the ERN shore and WRN shore of
the bay.

Short term 6 pm this evening through Wednesday
Weak surface low pressure tracks across nc tonight associated
with shortwave energy embedded within wsw flow aloft. Forecast
pops area generally 20-40% across SRN SE va nc nc, with thunder
maintained overnight due to the presence of some mid-level
instability. Partly to mostly cloudy with lows ranging through
the 60s.

00z 29 guidance continues to show that the cold front becomes
aligned parallel to wsw flow aloft Tuesday, stalling immediately
n of the region and perhaps pushing into the md ERN shore.

Meanwhile, the aforementioned weak surface low pushes off the
outer banks Tuesday morning. The chc for aftn evening
showers tstms will diminish Tuesday, though will continue with
20-40% pops in far SRN and SE va NE nc, and 20-30% for the nrn
neck ERN shore. Highs Tuesday range from the mid 70s to around
80 at the coast to the mid 80s inland, after morning lows
ranging through the 60s.

There will be little change in conditions Tuesday night into
Wednesday. An upper level trough will sharpen over the great
lakes Wednesday, but there is a lack of any trigger for
convective development Wednesday aftn. Lows Tuesday night range
through the 60s, followed by highs Wednesday in the upper
70s around 80 at the coast to the mid 80s inland.

Long term Wednesday night through Sunday
The long term period beginning Wednesday night will start off mainly
dry with high pressure over the mid atlantic states Thursday. The
high will merge with the bermuda high pressure ridge. This will
promote a slight warming trend and an increase of moisture. A
frontal boundary will settle over northern portions of the mid
atlantic states and help to trigger scattered mainly afternoon and
evening thunderstorms over the region.

High temperatures will range from 80 to 85 but slightly cooler at
the beaches. Lows of 60 to 65 Thursday and Friday mornings warm to
the mid to upper 60s Saturday and Sunday mornings.

Aviation 08z Monday through Friday
The current analysis shows low pressure off the DELMARVA coast,
with a weak ridge of surface high pressure over the piedmont.

Stratus and fog has developed over much of the area with
ric sby ecg experiencing lifr conditions, with periodic ifr
stratus at phf orf. Ifr lifr stratus and fog should prevail
through 12z, and potentially through 15z at sby. Drier
conditions arrive from the wsw as low pressure departs to the
ne today. There is a slight chc of mainly sea bay-breeze
showers tstms this aftn. Low pressure tracks off the nc outer
banks later tonight into Tuesday bringing a chc of showers and
embedded tstms to SE va NE nc. Mainly dry conditions are then
expected to prevail Wednesday through Friday. Patchy fog or
stratus is possible each morning within a few hours of sunrise.

Marine
Latest surface analysis centers weak low pressure just offshore
the delmarva, with a frontal boundary stretching along the
coast and into northeast north carolina. Winds are generally
northwest to west at 5-15 knots. Seas average 2-3 feet and waves
1 foot. Low pressure pushes farther offshore today as the north
carolina front lifts northward. A weakening cold front
approaches from the west. Light flow persists through the
afternoon, becoming onshore and increasing to 10-15 knots this
evening tonight as the front reaches the coast. Seas build to
2-4 feet (highest northern coastal waters) tonight. Waves 1-2
feet. The front stalls washes out along the coast Tuesday as
another weakening front approaches from the west. Winds
generally south of the south at 5-10 knots. The front pushes
just offshore late Tuesday night as flow becomes west to
northwest at 10-15 knots. Seas 2-3 feet. Another cold front
approaches from the west Wednesday, crossing the waters
Wednesday night. Weak cold advection behind the front results in
continued sub-sca conditions. High pressure builds over the
waters for the end of the work week.
