Another U.S. location not used to a lot of snow, let alone Blizzard conditions:
.SHORT TERM /WEDNESDAY THROUGH 6 AM WEDNESDAY/...
As of 615 AM Tuesday...
KEY MESSAGES:
- A winter storm will impact eastern NC with heavy snow,
dangerous cold, and strong winds
- Snowfall amounts have been increased and now all of eastern
NC is expected to reach warning criteria snowfall
Winter Storm Warnings have now been posted for all of eastern
NC for tonight. The developing offshore low will circulate very
moist air over the top of the arctic airmass. This will result
in widespread snow developing across the area this evening and
continuing for most of the overnight hours. The trend in the
models is for a continued slight inland movement of the heaviest
snow location with forecast amounts of >=3 inches covering a
very large portion of eastern NC. Based on this, the Winter
Storm Watch and Winter Weather Advisory have been upgraded to a
Winter Storm Warning.
As the right entrance region of the upper jet approaches and
ascent becomes maximized tonight, banded precipitation is likely
to occur which will lead to locally heavier snowfall amounts of
6+ inches. Right now it is very difficult to predict exactly
where these bands will form but they will most likely occur
along and just inland from the coast. Thermal profiles also
support periods of sleet occurring along the coast but still
expecting primarily snow to occur. The current snowfall forecast
has been increased and now is is calling for max amounts of 6-8
inches east of Highway 17. Gusty northerly winds will cause
considerable blowing and drifting of snow with blizzard
conditions possible along the Outer Banks where the strongest
winds and heavy snow will coincide. Cold ground temperatures
will allow the snow to rapidly accumulate which will make roads
snow covered and slick. No unnecessary driving is advised
tonight across the area. The snow should begin tapering off
around 9Z inland with accumulating snows expected to be over by
12z Wednesday.
