.NEAR TERM /THROUGH TONIGHT/...
As of 3 PM Wed...Main story today is the very warm temps and
gusty southwest winds. Tight SW pres gradient drawing extremely
warm air and gusting 30-35 kt winds to E NC. This in response to
approaching strong cold front currently located across the Ohio
and TN valley this afternoon. Main story for tonight will be
threat for a strong or severe thunderstorm. Instability
parameters overnight are marginal due to loss of diurnal
heating though shear is quite strong for any updrafts that
develop to tap into the efficient shear to produce mainly a
damaging wind gust or two. Unidirectional shear profiles so
tornado threat is very low to nil. Temps very warm overnight in
the 60s to around 70 until daybreak when the front finally
pushes through the coastal plain where temps will drop into the

will cross the area Friday afternoon accompanied by gusty NW
winds. Temperatures will return to normal levels for early March

settles near our area pushing lows into the upper 20s inland to
low/mid 30s coast. Inland areas will likely be below freezing
again Sunday morning with coastal areas in the upper 30s to mid
Monday night through Wednesday...While there are some model
differences in timing of precipitation, the overall pattern
shows high pressure moving offshore with increased S/SW flow
Tuesday into Wednesday. A strong cold front will be approaching
from the west with the GFS showing a strong mid-level shortwave
passing by to the north Tuesday night. Given the uncertainty at
