Time and Day: 0800 Wednesday
The Snapshot: This
wet weather with periods of rain and snow will extend into the upcoming weekend.
There is a good chance of some snow accumulation early tomorrow morning.
The Science: A complex low-pressure system centered off the
PNW coast will produce a mixed bag of snow and rain for the next few days. A cold front associated with a deep trough
could produce a period of heavy snow early tomorrow morning. Cooler air aloft appears to fill in behind
this feature allowing freezing levels to drop below 4000’ tomorrow and Friday.
The Long Range: Active weather continues through Saturday. At the moment, Sunday is trending dry with
temperatures returning to seasonal norms.
