Message summary: ...yet another major winter storm will affect our area from late
tuesday into wednesday evening...
.an explosively developing nor/easter will bring heavy snow to much
of our area starting late tuesday and tuesday evening and
persisting through wednesday.
...winter storm warning in effect from 4 pm tuesday to midnight
est wednesday night...
The national weather service in mount holly has issued a winter
storm warning...which is in effect from 4 pm tuesday to midnight
est wednesday night. The winter storm watch is no longer in
effect.
Low pressure moving from the texas gulf coast tonight will head
into the ohio valley tuesday. That low will give up its energy to
a coastal storm...which will develop along the northern north
carolina coast late tuesday and tuesday evening. By wednesday
morning... This nor/easter is forecast to intensify strongly just
southeast of our area...and likely bringing heavy snow to a good
part of our area overnight tuesday into the day on wednesday.
Southeast of interstate 95 the snow may mix with sleet and rain at
times during the first half of the day on wednesday. This is more
likely closer to the coast. But as colder air wraps around the
storm even these areas are expected to change back to all snow.
Total snow accumulations are expected to range from 10 to 18
inches with the highest amounts over the northern eastern shore of
maryland, northern delaware and eastern pennsylvania. Heavy snow
should occur in two bursts across the region. The first will occur
tuesday night with four to eight inches likely to accumulate by
the morning commute wednesday. The second shot will be an even
more intense burst of heavy snow with the upper air disturbance
itself that should occur in the philadelphia area, maryland and
delaware during wednesday morning and new jersey and northeast
pennsylvania during wednesday afternoon. The snow will end by
midnight wednesday night.
Winds will increase as wednesday continues and will cause
considerable blowing and drifting of snow, even more than what
occurred with the weekend snow storm. At and near the atlantic shore
blizzard conditions are possible later in the day on wednesday as
winds increase.
A winter storm warning means significant amounts of snow and
sleet are expected or occurring. Strong winds are also possible.
This will make travel very hazardous or impossible.
