End of Octoburrr downright bitter cold this weekend

Weather Blog

PORTLAND, Ore. (KOIN) — The biggest impacts in the wake of our latest cold front this weekend will be snow on mountain passes especially eastern Washington, very strong dry offshore winds (Mt. Hood Meadows reported 78 mph Friday night), and bitterly cold morning temperatures. As expected, rain was spotty in the valley as we were hanging out in the rain shadow. More consistent rain fell at the coast and across our mountain ranges. Sticking snow around Mt. Hood is possible this morning to midday, but if you’re looking for a winter wonderland, go east. Spokane so far – 8.5 inches of autumn snow!

Here are the latest advisories, watches, warnings:
Eastern slopes of the Cascades Winter Weather Advisory
NE Washington Winter Storm Warning
Seattle/and the I-5 corridor Freeze Watch
Rocky Mountains Blizzard Warning

A RECORD SNOWFALL OF 6.9 WAS SET AT SPOKANE WA AIRPORT YESTERDAY. THIS BREAKS THE OLD RECORD OF 0.2 SET IN 1957. IT WAS ALSO THE SNOWIEST DAY EVER RECORDED IN THE MONTH OF OCTOBER. THE PREVIOUS RECORD WAS 5.9 INCHES SET ON OCTOBER 22 1957.
