area forecast discussion

616 pm edt Fri mar 22 2019

Synopsis
A mainly dry cold front will move through eastern nc this
evening. High pressure will then build into the area this
weekend. A storm system is expected to impact the region early
to mid next week.

Near term through Saturday
As of 615 pm fri... No changes to previous forecast thinking a
reinforcing cold front will move through the area this evening.

Not alot of moisture to work with, but may be enough to generate
some sprinkles or an isolated shower across the N NE portions
of the forecast area early this evening, so will continue 20%
pops for a few hours early this evening across the northern
tier. Breezy NW winds and strong CAA develop behind the front
tonight. Temps will drop into the upper 30s inland and upper
30s low 40s along the coast.

Short term Saturday night through 6 pm Saturday
As of 3 pm fri... Deep layer subsidence will keep clear dry
conditions in place. High pressure building into the region
from the northeast will bring northwest winds, and high temps
will be near to a couple of degrees below normal, ranging from
the mid 50s northeast to lower 60s southwest.

Long term Saturday night through Friday
As of 3 pm Friday...

Saturday night and Sunday... Large scale subsidence will keep
clear dry conditions in place through Sunday night. The surface
ridge will pass overhead early Sunday, with calm winds and clear
skies leading to efficient radiation cooling. Temps are
expected to reach the mid to lower 30s for most areas away from
the immediate coast early Sunday morning, which will result in
widespread frost and possibly an early- spring freeze. Will
continue to highlight frost freeze threat in hwo.

The high will move offshore during the day Sunday, with
developing light southerly flow bringing noticeably warmer temps
compared to Saturday. Aloft, a weak shortwave will shift from
the mid plains states into the ohio river valley as troughing
digs across the eastern us with upper level cloud cover
increasing through the day. However, persistent downsloping mid
level flow will ensure that a dry forecast remains in place for
Sunday and Sunday night. Sunday night min temps will range from
the mid 40s inland to low 50s along the coast.

Monday and Tuesday... Large scale troughing develops across the
eastern us Monday. At the surface, a cold front approaching from
the west will cross the area Tuesday morning bringing the
highest rainfall chances Monday afternoon into Tuesday morning.

Greatest source of uncertainty with the forecast involves
divergence aloft associated with a southern stream jet streak to
our south, which may develop a wave low within the front. The
effects of this feature on moisture transport, instability, and
frontal passage timing locally remains to be seen, but low end
likely pops with the primary band of pre-frontal moisture
remains in the forecast for the time being. Forecast soundings
indicate a marginal setup for thunderstorms Monday afternoon
with weak instability (<300 j kg) and shear (<30 kt 0-3km), so
have added slight chance thunder for the afternoon hours.

Sw flow in strong WAA will build temps into the 70s inland
Monday with 60s along the coast, due to airmass moderating from
nearby water temps in the upper 50s. The front moves through
Tuesday with falling heights, precip, and northeasterly flow
capping MAX temps into the mid 50s south to low 50s north and
inland.

Wednesday and Thursday... Ridging is expected to develop aloft
for the end of the period as high pressure centered over the
northeast ridges down the east coast. A mainly dry forecast is
in place given the dry airmass that will prevail inland.

However, low end precip chances will linger over far eastern
portions, possibly including the outer banks at times, as a
low pressure system develops offshore wrapping around moisture
towards the obx coastal waters. It remains to be seen how close
the low will be to the coast, or if it will be far enough away
to only influence surface winds with no precip. Below normal
temps will prevail as we move into the second half of next week.

Aviation 22z Friday through Wednesday
Short term through Saturday ...

as of 615 pm fri... High confidence inVFR conditions through
the TAF period. A mainly dry cold front with only isolated
showers will move through early this evening followed by high
pressure late tonight and sat. Any ceilings early this evening
will be >5k ft and precipitation too light to restrict
visibility. Main concern will be a period of gusty NW winds to
30 kt following the passage of the cold front around 2z, then
winds should diminish overnight, then increaes again Sat mid
morning with gusts to 20 kt possible.

Long term Saturday night through Wednesday ...

as of 3 pm Friday...VFR conditions will prevail through Sunday
night. A cold front will approach from the west early next week,
and increasing moisture ahead of the front will bring the
potential for at least periods of flight restrictions beginning
Monday morning. Sub-vfr conditions become more likely late
Monday through Tuesday, especially once winds shift northerly
late Monday night into Tuesday morning. High pressure builds
back in for Wednesday resulting inVFR conditions.

Marine
Short term through sat
as of 615 pm fri... No changes to previous thinking. West flow
15-25 kt early this evening will veer to northwest late this
evening into Sat morning as a cold front sweeps through. High
pressure will then begin building into the region from the
northwest. NW winds will diminish to 10-20 kt Sat afternoon as
the high builds into the region from the northwest. Seas 3 to 5
ft with some 6 footers outer waters early this evening will
build to 4-7 overnight then subside to 3-5 late sat.

Long term Saturday night through Wednesday ...

as of 3 pm Friday... Winds will become light Sunday and Sunday
night as high pressure moves overhead and off the coast. A cold
front approaches from the west Monday, bringing increasing
southwesterly winds. The cold front will cross the waters early
Tuesday, with strong northeasterly winds expected behind the
front through the middle of next week. Scas may be needed with
the pre- frontal southwesterly winds, but there is higher
confidence that advisory or warning level winds will occur
behind the cold front.

Seas will gradually subside through the weekend, becoming 1 to
3 ft by late Sunday. Then, seas will increase as southerly wind
swell develops ahead of the approaching cold front Monday. Large
and dangerous seas are possibly as strong northeast winds
develop behind the cold front Tuesday through midweek.

Fire weather
As of 3 pm fri... Clear and dry conditions expected Saturday.

Winds will be from the northwest 10-15 mph during the day, with
min rh values once again 25-30%. Given recent rains do not
anticipate widespread fire weather concerns, but the low rh
values northwest winds could lead to an increased threat of fire
danger.

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.
