Area Forecast Discussion
National Weather Service Newport/Morehead City NC
645 PM EDT Wed Mar 29 2017

High pressure extending down the east coast from southeast Canada
will move east Thursday. A warm front will move through from
the southwest Friday, followed by a cold front early Saturday.
Another warm front will lift north through the area Monday
night, followed by a cold front late Tuesday, or Tuesday night.


As of 645 PM Wed...Latest sfc analysis shows 1031mb high
pressure centered over Southern Ontario and the Great Lakes
region, extending into the Mid-Atlantic and Southeast US.
While latest satellite imagery shows area of scu along Hwy 17
beginning to erode early this evening. Expect skies to become
mostly clear later this evening, with increasing clouds early
Thu morning. Think increasing clouds late and winds staying up
will inhibit fog development overnight. Cooler overnight with
lows dropping into the mid to upper 40s.


As of 230 pm Wed...High pressure along the coast will move east
in the afternoon. Moisture will increase during the day ahead
of the warm front advancing this way from the southwest. Light
northeast wind in the morning will veer to east in the
afternoon. Highs will vary widely, from the mid/upper 50s
northern Outer Banks to upper 60s/70 degrees southwest.


as of 230 PM WED...Shra and tsra expected Fri and Fri evening
then again Mon night into Tue...otherwise mainly dry with
pleasant temps

Thu night through Fri night...Moisture will increase quickly
Thu night as high pres slides offshore and next system
approaches from the W. Expect sct shra late...mainly inland with
mild lows in the upper 40s to lower 50s. Numerous shra and tsra
expected Fri as strong short waves lifts NW of region producing
good lift over the area. Good srly low lvl flow will lead to
precip water values reaching around 1.5 inches and expect
widespread rainfall totals of 1/2 to 1 inch with locally higher
amounts. Forcing and shear favorable for severe weather however
degree of instab in question with clouds precip developing
early...if do get pockets of better instab will certainly have
a severe threat. Shra and a few tsra will grad end from with to
E Fri night as cold front crosses.

Sat and Sunday...Dry with pleasant temps over the weekend with
broad ridge aloft and sfc high building in from the NW. Highs
Sat 60s beaches to 70 to 75 inland...bit cooler Sunday with
highs mid/upr 50s OBX to upr 60s/lower 70s inland.

Mon thru Wed...Moisture will be returning Mon with high pres
moving offshore and next srn stream system approaching. Expect
increasing clouds with sct shra and tsra mainly in the aftn.
Numerous shra and at least sct tsra expected Mon night into
first part of Tue as the potent srn stream short wave lifts NW
of region. Much like Fri forcing and shear look favorable for
severe potential but still some uncertainty on instab. Will be
mild early next week with highs Mon and Tue in the 70s inland
to 60s beaches.

Cold front will be offshore by early Wed with dry weather
expected. Very little cold air expected behind front with highs
Wed again reaching the 70s inland to 60s beaches.


Short Term /through Thursday/...
As of 645 PM Wed...VFR conditions currently, as area of stratocu
along Highway 17 continues to slowly erode this evening. Expect
skies to become mostly clear, with increasing clouds early
Thursday morning. Confidence is low at this time, but think
increasing cloud cover late and light winds will inhibit fog
development overnight...though a brief period of MVFR conditions
will be possible early Thursday morning. Pred VFR conditions
expected Thu with cloud bases gradually lowering with increasing
moisture ahead of the next frontal system.

Long Term /Thursday night through Monday/...
As of 230 PM Wed...Mainly VFR Thu evening then as moisture
increases late could see some sub VFR develop in sct shra prior
to day break Fri. Numerous shra and tsra Fri into Fri evening
ahead of a cold front with ocnl sub VFR likely...a strong storm
or two also possible. Shld dry out later Fri night with VFR
expected over the weekend as high pres builds in from the NW.
Moisture will be returning Mon in advance of the next system
with sct shra/tsra and poss some sub VFR.
