Otherwise, the gulf low which we`ve been monitoring for several days
now still has the potential to produce some snow showers across our
southeastern zones this afternoon and tonight. More of the latest near-
term guidance now depicts a bit more QPF along and south of the I-85
corridor. The best forcing and moisture remains at mid and upper lvls,
while low levels remain dry. Mid-level isentropic lift will spread NE
across the region this afternoon, but with such a dry and deep sub-
cloud layer, much of what falls from the mid-level clouds will likely
be lost to evaporation. Nonetheless, snow flurries are probable this
aftn/evening as this lift strengthens, and it`s looking like we may
see some accumulating snow along and south of I-85. After consulting
with our neighboring fcst offices, we decided to go ahead and issue
a Winter Wx Advisory for snow, that runs from 4 pm today until 9 am
Wed morning. This was largely driven by the potential impacts on roads.
With the cold air in place, any accumulating snow may cause significant
impacts on roadways. Temperatures, meanwhile, will continue to be well-
below normal thru the period, barely getting above 32 degrees over much
of the fcst area today.
