NWS now mentioning a dusting here possible Monday
Near the time of precipitation onset, surface winds will reverse
to northerly with cooler air sloshing back in. CMC/ECMWF forecast
soundings suggest precipitation will initially be rain in all
areas, but as temperatures wet bulb and the mid level atmosphere
cools in the wrap around, snow will likely begin to develop. As
noted previously, there is still uncertainty with respect to when,
where, and how long a transition to snow would take place. In
general, it appears likely many locations will at least see snow
in the air for a time Monday evening and a minor dusting of snow
is possible for much of the area, but especially over areas of
higher elevation. In those locations minor accumulations
(Trace-1" or so) seems reasonable. There is still a low
probability (10%) that heavier precipitation rates (like the GFS)
could result in higher totals and over a broader area.
