Time and Day: 0900 Sunday
The Snapshot:
Mixed rain and snow showers today.
More storms with snow potential on the way next week.
The Science: A
low pressure system tracking north over the offshore waters will spin bands of
moisture into the mountains today and tomorrow.
Warm air advection will begin invade along the western slopes of the
Cascades today; this will bump freezing levels +- 5000’ this afternoon. There
will be a break in the action tomorrow with the next frontal system arriving on
Tuesday.
The Long Range: The next +-7 days will be very active with
several storms heading towards the PNW. This
incoming storm cycle is riding on a NW jet stream which, at the moment, has
freezing level in favor of snow. Stay
tuned as usual.
