Time and Day: 1100
Sunday
The Snapshot: Snow
tapering off with clear periods this afternoon.
More snow and continued cooling tomorrow. Cold and dry for Tuesday and Wednesday, with
more snow and warming to wrap up the
week.
The Science: Whew, what a storm with +20” of snow and
counting. The convergence showers are starting
to wane with partial clearing beginning.
Pressure gradients will ease a bit today which will produce a short
break in the precipitation through early tomorrow morning. Strong northwest flow will usher in the more cold air with freezing levels dropping to
or below 500’ tomorrow.
A low-pressure trough will track through tomorrow
with more snow for Stevens. A high
pressure ridge will strengthen tomorrow night which will produce dry, cold and
clear conditions Tuesday and Wednesday.
Cold temperatures will settle in
with early morning temperatures in the lower teens tomorrow and possibly single
digits by Wednesday morning.
The Long Range: More excitement starts on Thursday as the
next series of frontal systems prepares to enter the region. Details are still in question, but snow is
likely with warming starting Thursday and lasting into the weekend.
