905 pm edt Tue mar 20 2018
Low pressure will develop off the outer banks tonight
and then intensify off the DELMARVA coast Wednesday, before
gradually pushing offshore Wednesday night. High pressure gradually
builds into the area late in the week.
Near term until 6 am Wednesday morning
9 pm update... Afternoon forecast in good shape, with only minor
tweaks to temps necessary.
Latest satellite imagery shows significant TSTM activity off
the sc nc coast, as upper shortwave interacts with the
gulfstream. In addition, band of shwrs tstms has continued
rotating around upper low from SRN wv into central nc. Hi-res
models suggest this feature will rotate into the region
overnight, then be north of the area before noon Wednesday. Hi-
res models also suggest this feature may contain the most
important precip for the rest of the event, with NAM suggesting
much of the snow behind this system will be light, and therefore
have difficulty accumulating. Will not make any changes to
current advisories warnings, as there is not enough information
to begin changing snow amounts. However, mid shift will need to
closely monitor the band of shwrs tstms to our W SW being the
main precip producer the next 24 hours. In addition, large tstm
complexes offshore often lead to mitigating the amount of qpf
for a system developing to the N nw. All of this will need to be
evaluated by mid shift. For now, no changes to current precip
forecast next 24-30 hours.
4 pm discussion... Current WV imagery depicts a powerful upper
trough pushing across the southeast conus, with an area of
surface low pressure off the va capes and another area of broad
low pressure developing across sc, and this will become the
primary low tonight into Wednesday. High pressure N of the great
lakes is presently ridging swd through the piedmont, which is
resulting in a cad airmass under extensive stratus, and largely
a lull in rain with the exception of the ERN shore. Temperatures
range from the mid 30s over the NW piedmont to the mid
40s around 50f for coastal SE va NE nc.
This powerful complex system will continue to impact the region
tonight. The 20 12z GFS nam ECMWF continue to depict the surface low
deepening tonight in vicinity of the outer banks. Pcpn arrives from
the SW later this evening, with the potential for NW portions
transitioning to snow after midnight, with the change to snow for
the ric metro occurring from 3-6 am. Much of the overnight
accumulation of snow should be NW of ric and mainly 1-2". More
discussion on accumulation, warnings, and advisories is discussed in
the short term section below. Pops ramp up to categorical tonight.
Lows range from the low 30s NW to the upper 30s around 40f se.
Short term 6 am Wednesday morning through Friday
The upper level system passes ewd in vicinity of the
va nc border Wednesday morning, with surface low pressure
intensifying off the mid-atlantic coast. The upper level system
slides offshore during the aftn with the overall system becoming
stacked and nearly stationary off the coast during the 18-00z time
period. This will bring the potential for banded pcpn (in the form
of snow) across the DELMARVA and perhaps the NRN neck.
The upper level system pulls in enough cold air to allow a
transition to snow for ERN portions of the are Wednesday. Likely to
categorical everywhere through through midday Wednesday as the
forcing from the upper level system taps into moisture, and
categorical pops over the ERN shore into the aftn. Thicknesses
suggest rain mixing with snow over the ERN shore Wednesday morning
(dorchester may become all snow by daybreak), then becoming all snow
by aftn evening. Farther W (i-95 corridor to the piedmont)
thicknesses suggest all snow while pcpn occurs, with snow tapering
off from sw-ne during the aftn, and possibly mixing with light rain
at the tail end. A cold rain for SE va NE nc could mix with some
snow Wednesday aftn early evening. The current forecast is for 3-5"
for caroline county and the NRN neck, and somerset wicomico md, with
the potential for 4-6" for dorchester md. These areas have a winter
storm warning. Elsewhere, 1-3" of snow is forecast in a corridor
along a fvx-ric-wal line where winter weather advisories are in
effect. The primary impact will be falling snow with conditions
improving once the snow ends. Accumulation on roads will be
dependent on intensity, otherwise, expected accumulation mainly on
the grass and elevated surfaces. Accumulation farther S should be 1"
or less, and little to no accumulation for far SE va coastal NE nc.
Highs Wednesday will be in the mid 30s where snow falls to the upper
30s low 40s where rain prevails. Highs in south central va may rise
to around 40 f later in the aftn as the precip intensity diminishes.
Drier air arrives late Wednesday night through Friday as the system
pulls to the northeast. Partly to occasionally mostly cloudy under
the upper trough. Lows Wednesday night range from the mid upper 20s
nw to the low 30s se, with highs Thursday in the mid to upper 40s,
possible cooler over the md ERN shore depending on snowfall
Wednesday. Some re-freezing could occur early Thursday morning
especially if there is (partial) clearing late Wednesday night. Lows
Thursday night range from the mid 20s to low 30s, with highs Friday
in the mid 40s to around 50f.
Long term Friday night through Tuesday
Region remains influenced by large scale upper trof through most
of the extended period. Area is between systems Friday night and
most of Saturday. A shortwave trof will be approaching from the
west Saturday night, and move across the area on Sunday. 12z
gfs ECMWF are at odds with regard to how far north precip gets
with this shortwave. Have gone with a blended solution, which
gives a chance of rain snow across much of the area. Shortwave
moves offshore Sunday night, with ridging surface and aloft
gradually building into the region Monday through Tuesday.
Overall, cold high pressure building in from the the NW will
provide a continuation of below much below normal temperatures
for much of the forecast period.
For temperatures, highs Sat around 50f inland... M40s at the
coast. Lows Sat night generally 30-35, with some upper 30s ne
nc. Highs Sun in the 40s to around 50 f, and Mon mid to upper 40s
n DELMARVA to mid 50s southern portions of interior NE nc. Highs
Tuesday around 50 lower md eastern shore to the upper 50s|
interior NE nc. Lows Sunday night Monday night in the low to mid
Aviation 01z Wednesday through Sunday
Low pressure is located east of the DELMARVA at 23z, with
another area of low pressure situated over eastern sc.
Meanwhile, high pressure centered N of the great lakes is
ridging swd through the piedmont. Little if any precipitation
occurring across the region at 00z. However, there are
showers tstms along the nc coast lifting newd, and additional
showers tstms in SW va WRN nc, also moving newd. Expect
precipitation to re-develop move back into the area in the
04-06z time frame, later at ksby. In the meantime ifr cigs
should prevail this evening although there could be occasions
where CIGS lift to MVFR around 1.0-1.5kft. As the 2 low pressure
areas mentioned above begin to consolidate off the delmarva
coast, rain will change to snow from NW to SE across the area.
The changeover should reach kric by 12z, ksby kphf around 16z,
and korf around 18z. All in all, the 00z TAF period will be
dominated by ifr lifr in low ceilings and precip. A N wind of
10-15kt with gusts to around 20kt is expected, especially near
the bay ocean.
Snow potentially lingers at sby Wednesday evening. Otherwise,
drier conditions arrive later Wednesday night, with dry andVFR
conditions prevail Thursday and Friday. Low pressure approaches
from the W late Saturday, with the potential for sub-vfr flying
conditions by early Sunday.
A couple of low pressure areas will combine into one and
intensify just off the mid atlc coast tonight into Wed morning.
That strong low pressure system will then slowly lift NE off the
delmarva and new england coasts Wed into thu. This will produce
strong ne-nw winds over the waters tonight thru thu, with gale
warnings now in effect for the NRN three coastal zns until 7 pm
wed, and sca's now in effect for the remainder of the marine zns
until 1 pm or 4 pm thu. Expect wind gusts to arnd 40 kt over
the NRN two coastal zns thru tonight, then gusts to around 35 kt
during wed. Seas will be between 8 and 13 ft over the nrn
coastal zns thru wed, and between 6 and 9 ft over the srn
Low pressure will move away twd into the NRN atlc late Thu thru
fri, allowing for conditions to slowly relax. High pressure
will finally build over the area by sat. Another low pressure
system may impact the waters by sun.
Tides coastal flooding
Tidal departures build this evening through Wednesday and there
will be the potential for at least minor coastal flooding for
locations adjacent to the lower bay and the atlantic coast. Went
ahead and issued a coastal flood watch for coastal portions of
worchester county where guidance continues to indicate the
potential for moderate flooding Wednesday. Expect for tide
departures to run from 2 to 3 feet above normal tide around
times of high tide.
