LWX picking up on the freezing rain threat in their latest disco: @losetoa6
Latest 12z guidance, particularly the NAM and EURO,
suggests that there may be enough cold/dry air advection behind
the cold front for areas of freezing rain to develop overnight
Thursday through mid-morning on Friday. The best chance for
freezing rain will be across western and central Maryland, parts
of eastern West Virginia and into the northern portions of the
Shenandoah Valley. A few sleet pellets are possible across
these areas as well.

.LONG TERM /FRIDAY THROUGH TUESDAY/...
A frontal boundary will linger over the area Friday as a low
pressure system tracks northeastward through the Midwest. An
interesting synoptic set-up with high pressure over Bermuda and weak
high pressure over New England. This poses a steep temperature
gradient at the onset of precip which occurs Thursday night. While
much of the southern half of the region is likely to remain
above freezing, NAM, EURO and EURO ensemble members indicate
freezing rain, primarily along the MD/PA border, down through
the Shenandoah Valley and the Allegheny Front. At this time, it
seems possible that freezing rain does indeed develop for those
areas.
