.DISCUSSION...
Snow over much of the CWA this afternoon will continue this
evening before it/s expected to end from west to east late
tonight. Dynamics with a backdoor front just west of the CWA have
brought isentropic upglide that brought more snow today than
expected.

Surface high pressure will help clear things by Tuesday morning
across the northern zones with another disturbance set to bring
more snow across the southern zones.

Will keep going advisories up but Wind chills will be the next
concern for the northern zones starting Tuesday.

A bitter night is expected Tuesday Night with fresh snowcover and
clear skies (across the NE zones).

Then a zonal Pacific flow will ensue beginning Wednesday which
will allow temperatures the remainder of the week to approach
normal levels. Mainly dry conditions are expected but a deepening
upper trough over the Pacific Northwest this weekend may have to
be watched. TFJ
