Synopsis
Arctic high pressure will build into the area today, then drift
overhead tonight through early Tuesday. This high pushes offshore
Tuesday night, allowing a milder air mass to overspread the
area by midweek. The next storm system impacts the area by
Thursday.

Near term until 6 pm this evening
As of 340 am est Monday...

we're starting off this morning quite cold as arctic high
pressure has begun to overspread the fa. Current readings are in
the teens and 20s, but after factoring in the NW wind of 10-15
mph, gusting as high as 25-35 mph along the coast, we get wind
chills from zero to 5 below north and 5 to 15 degrees south. A
wind chill advisory remains in effect for northern areas through
9 am est.

850mb temperatures fall to near -22c N to around -18f this
morning and only moderate slightly through midday. The arctic
high will continue to build in from the NW with breezy
conditions continuing toward to coast. High temperatures only
rise into the low 20s N to upper 20s nr 30 s. Wind chills will
likely remain in the single digits through midday from the nrn
neck to the ERN shore.

Short term 6 pm this evening through Wednesday
As of 625 am est Monday...

the arctic high builds over the area tonight into Tuesday
morning when most numerical guidance depicts it as a 1040mb high
centered over the mid-atlantic, before it slides offshore in the
aftn. Tonight will likely be the coldest night with lows
ranging from the single digits over the NW piedmont, to the
low mid teens from central s-central va to the md ERN shore, and
upper teens for far SE va NE nc under a clear sky. Highs
Tuesday range from the mid 30s N to near 40f S under a sunny sky
with perhaps an increase in thin high clouds late.

The high remains near the coast into Tuesday evening, so
temperatures should cool quickly under a mainly clear sky. Lows
in the mid 20s to low 30s may be achieved in the evening,
before temperatures become steady or slowly rise overnight with
increasing clouds. A warm front will lift through the area
Wednesday. Becoming mostly cloudy, but milder with highs ranging
from the low 50s NW to the low 60s se. There is a 20-40% chc of
light rain from the piedmont and south-central va northeast to
the lwr md ERN shore. Depending on how quickly any light rain
arrives early Wed morning, there is a small window of
opportunity that temps may still be at or just below freezing
across the piedmont. This is something that bears watching. Best
opportunity for any light freezing rain may be just west & sw
of our fa.

Long term Wednesday night through Sunday
As of 355 pm est Sunday...

a frontal boundary is expected to approach the region Wednesday
night before slowing down stalling across the region during the
day on Thursday. A wave of low pressure develops across the
southeast and will ride along this frontal boundary, leading to
high pops late Wednesday through Thursday. Rainfall could be
heavy at times at Thursday with model guidance showing an inch
or more of QPF for the region with this system. This will be
primarily a rain event for our region with mild temperatures,
but it is possible a few snow flakes mix in (especially across
our north and west) as the system departs late Thursday and
cooler air works into the region. Dry weather and falling
temperatures for the remainder of Thursday night as northwest
flow sets up across the region. Another front, this one arctic
in nature, approaches and crosses the region during the day on
Friday. The GFS hints at the potential of some light snow
showers with this front, especially across our north, but other
models remain less robust with this system. For now, just
limited pops to a slight chance across the northern half of the
region. Cold high pressure builds in behind the front Friday
night and Saturday which will allow for another period of well
below normal temperatures for the first half of the weekend.

Aviation 12z Monday through Friday
As of 625 am est Monday...

vfr conditions will persist across area terminals through the
taf period. High pressure will gradually build into the area
today, with the gradient remaining strong near the coast. A nw
wind should generally be 15-20kt, with gusts of 25-30kt under a
sunny sky.

Outlook: high pressure builds over the region tonight and
passes across the area Tuesday and the wind will diminish. High
pressure moves offshore Wednesday, followed by another low
pressure system that affects the area Wednesday night into
Thursday. This system will likely bring more rain and flight
restrictions. High pressure briefly returns Thursday night,
before another cold front approaches Friday.

Marine
As of 340 am est Monday...

winds diminishing west of the ches bay dropped the gales and
replaced with strong SCA across the rivers and currituck sound.

Gusts continue to exceed 35 kts across the ches bay and coastal
waters so will continue the gale headlines there. Models show the
gradient slowly diminishing thru the day and expect the rest of the
gales to be replaced with sca's by 00z. Seas 5-8 ft with 4-5 ft
waves will slowly subside as well by tonite. Given current sfc tmps
and wind speeds, freezing spray advsry remains in place.

Winds seas continue to improve tonight into tues as high pressure
builds into the region, but SCA winds and seas AOA will likely
continue through 12z Tue over the bay ocean. High pressure becomes
centered over the waters by Tue aftn, slowly shifting the winds to
the south Tue night and Wed at speeds AOB 15 kts. Another area of
low pressure is progged to approach the waters Wed night. At this
time, it looks like winds increase out of the S and may reach sca
thresholds late wed-thu (coupled W increasing waves seas). Winds
turn to the NW in the wake of the low Thu night, but will remain
around or just below SCA thresholds.

mechanical failure.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
