0830 Monday:
The Snapshot: Snow tonight, drying and warming for the remainder of the week.
The Science: Another cold
front is in route with more snow for the Cascades. Light snow should begin to
fall in a few hours and intensify this afternoon/evening. Our friend, the convergence zone, will start
out at Stevens and then shift south toward Snoqualmie Pass early tomorrow
morning. This system is not packing as
much precipitation as the last storm, but hopefully Stevens will pick up enough
new snow for some more powder turns tomorrow.
Long Range: It all comes to and end tomorrow
afternoon as high pressure begins to build up from the southwest. The rest of the week will trend clear and
warm. Freezing levels by the end of the week
could peak above 10,000’ with daytime temperatures in the 60’s.
