CTP has this near term update this evening.
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Lots of sleet over York and Lanc counties and even working up
toward Harriburg and Lebanon, now. This will hold the numbers
down, but may make it even more difficult travel-wise since
people drive on the sleet and compact it, making it a sheet of
ice. That can be tough for the plows to clear. Snow has returned
to THV, though as the precip has lightened up. Dry slot
expanding a bit as it moves into far srn PA. But, instability
still there with thundersnow over Mt Davis (Somerset Co). The
dry slot is somewhat concerning as any break of a couple of
hours would kill the snow totals if we don`t see the N-S
oriented bands set up and move at a turtle-like pace. There are
bands over wrn PA (with the thundersnow) and it still looks like
we will have the same conditions over central PA for the first
half of the night. The lack of seeding over the clouds in the
dry slot means it will be a snizzly/freezing drizzle which could
fall for those couple of hours from now until 8 or 9 PM. The
HRRR has the snow closing in around the dry slot about that
time. Will mention --ZR for the next few hrs in the srn
mtns/lower susq.
