Synopsis
A cold front stalls north of the region late tonight through
midweek. Meanwhile, weak low pressure tracks across north
carolina tonight and off the outer banks Tuesday.

Near term until 6 am Tuesday morning
Latest surface analysis places weak low pressure now well off
the DELMARVA coast, with associated sfc warm front lifting
across the DELMARVA at 19z. To the west, a slow moving cold
front crossing the central appalachians from the mid-south ohio
valley. Aloft, deep occluded cyclone continues to spin over the
upper great lakes into ontario, with the associated surface
cold front extending from the great lakes back into the central
plains.

Latest goes-16 low to mid level WV imagery showing increasing
moisture pushing across the area from central nc, with a
deepening CU field across the lower mid-atlantic this afternoon.

Southern half of the area is largely capped, but have noted a
few isolated showers storms as expected along the E va coast in
association with sea bay-breeze. Therefore have a 20% pop along
and east of i-95 for the late aftn hours. Sky cover averages
partly to mostly cloudy for the late afternoon hours, with a
lull in precipitation still expected early in the evening.

However, expect showers to re-develop by mid to late evening,
owing to an area of weak low pressure lifting across central nc
toward SE va NE nc after 00z 8pm edt tonight W associated
shortwave energy pushing across the southern third of the area
within wsw flow aloft. Forecast pops area generally 20-40%
across southern SE va into NE nc late tonight, with a narrow
area of likely pop installed along and north of the albemarle
sound. Thunder mention has been maintained overnight due to the
presence of some mid-level instability. Becoming mostly cloudy
overnight with lows ranging through the 60s.

Short term 6 am Tuesday morning through Thursday
Weak diffuse sfc cold front becomes aligned parallel to w-sw
flow aloft Tuesday, stalling immediately n-nw of the region.

Meanwhile, the aforementioned broad surface low pushes off the
northern outer banks Tuesday morning, with a lull in pcpn once
again anticipated for much of the morning early afternoon.

Another period of isolated to widely sct showers and t-storms is
anticipated on Tuesday. However, areal coverage will be confined
primarily to the SE cwa. Model consensus indicates that forcing
will be a bit more muted across the local area, with stronger
shortwave pushing across SW to NE across eastern nc Tuesday,
just southeast of the local area. Therefore, pop remains in
20-40% range over far 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 through
Wednesday. Good model agreement exists that deep upper trough over
ontario upper great lakes sharpens Tuesday night and Wednesday.

However, there remains a lack of any trigger for convective
development during this period with mid-level flow becoming
downslope by afternoon. Therefore , have again capped pops at no
higher than slight chance Tuesday night, and mainly dry (except far
se) on Wednesday. Lows Tuesday night range through the 60s, followed
by highs Wednesday in the upper 70s around 80 at the coast to the
mid-upper 80s inland.

Mid-level trough axis will shunt surface cold front across the area
Wednesday night. Given later timing, have maintained only a slight
chc for showers and storms for now. Post-frontal w-nw flow and
surface high pressure building from the west should combine to yield
a dry forecast on Thursday. After early morning lows in the upper
50s to mid 60s, look for highs Thursday in the low to mid 80s
inland... Mid to upper 70s lower eastern shore and along area
beaches.

Long term Thursday night through Monday
Another unsettled period ahead as the models show a frontal boundary
stalling across the region next weekend with several waves of low
pressure moving along it. This combined with upr level energy and a
good low level moisture feed results in chc pops late Friday through
Sunday night, except likely Sat afternoon and evening as that seems
to be the time frame of the most significant low. Data suggests
locally heavy downpours with another widespread 1-2 inch rainfall
psbl. Highs 80-85. Lows mid-upr 60s.

Latest trends show the system moving offshore Mon with weak high
pressure building into the region. Kept slght chc pops for now until
better confidence of removing pops. Cooler with highs 75-80.

Aviation 21z Monday through Saturday
As of 17z... A warm front was lifting northeast through the maryland
eastern shore. A weak cold front will move through this evening.

Another weak cold front will cross the area from northwest to
southeast Tuesday evening with a stronger front coming through
on Wednesday night.

In the wake of the clearing of stratus... Cumulus was developing
across the area. Winds from the west and northwest will shift back
to easterly toward evening. With onshore flow... Another round of
MVFR ifr stratus and some fog will likely develop overnight and
slowly improve mid to late morning Tuesday.

Outlook... Scattered mainly late day and evening thunderstorms are
expected Tuesday with rather isolated activity late Wednesday. Dry
weather is forecast Thursday. Chances for convection return Friday
afternoon and become a likelihood on Saturday afternoon. Patchy fog
or stratus is possible each morning within a few hours of sunrise.

Marine
No headlines expected despite a number of wind shifts this week. A
weakening cold front crosses the area tonight with s-se winds
averaging 10-15 kts behind it. Seas 2-4 ft, highest off the md
coast. The front washes out along the coast Tuesday as another
weakening front approaches from the west. Winds generally s-sw at 10
kts or less. The front pushes just offshore late Tuesday night as
flow becomes west to northwest at 10-15 knots. Seas 2-4 ft.

The next cold front crosses the waters Wed night. Only weak caa
progged behind it resulting in continued sub-sca conditions. High
pressure builds over the waters for the end of the work week.

Tides coastal flooding
High astronomical tides combined with an onshore flow will
result in another round of near to minor flooding issues with
tonights high tide cycle. Thus, coastal flood advisories
statements have been issued to cover the next high tide cycle.

Akq watches warnings advisories
Md... Coastal flood advisory from 9 pm this evening to 2 am edt
Tuesday for mdz024-025.
