LWX mentions the big south trend in their afternoon disco!!!
Meanwhile, another disturbance will emerge out of the West Coast
trough and rapidly track up over the central US ridge Thursday into
Thursday night, before diving east-southeastward toward the Mid-
Atlantic on Friday. Guidance has shifted significantly southward
with the track of this system with each of the last few model runs.
As a result, many solutions now show wintry precipitation across the
northern half of the forecast area (roughly I-66/US-50 northward).
Of the solutions that do have wintry precipitation, most favor
freezing rain and sleet, but some snow can`t be completely ruled out
depending on the ultimate track of the system. The upstream flow
pattern across the North Pacific (from which this system will
originate) is highly complex at the moment, with critical pieces
that will come together still to the west of the California coast,
in the Gulf of Alaska, and in the Bering Strait. Another closed
upper low to the west of Hawaii will likely also have a major impact
on how the West Coast trough evolves. As a result, there could still
be significant shifts with respect to the track of this system over
the next few model runs, and confidence in the forecast is much
lower than normal for five days out.
