Time and Day: 1000
Thursday
The Snapshot: Snow
showers will persist through the weekend with a return to average PNW
temperatures and precipitation. Next week will trend dry and clear.
The Science: The lesson for yesterday's
“rain’ event – don’t underestimate the power of east flow, even if the models
don’t agree. Moving on.
A series of low-pressure troughs
offshore, coupled with a high pressure
ridge setting up over the interior, will allow passing snow showers with clear
periods to move through the mountains for the remainder of the week. Freezing
levels will settle on a consistent elevation somewhere around the 2500’-3000’ range
for the next several days.
The Long Range: This showery pattern will likely persist
through the weekend. The storms head
south early next week with a ridge of high pressure building over the PNW.
