Just woke up and checked out radar; here we go! Storm #3 is moving in WAY ahead of schedule today with heavy snow across the metro area already before 10am. It appears the atmosphere is still cold enough to support snow (for now) north of Salem. A new winter storm warning is up now through tomorrow morning for most of the Willamette Valley and now an Ice Storm Warning for the central/south Willamette Valley due to very thick ice accumulations.
- Expect 4-7″ new snow in most of the metro area today/this evening.
- Most of the precipitation should stay as snow in the metro area
- Some freezing rain is possible in the metro area by evening, definitely possible during the overnight hours
Heavy freezing rain will develop in the Willamette Valley and snow will change to freezing rain from Salem up into the far southeast suburbs of the metro area during the afternoon. Lots of thick ice developing and power outages!
Note the WRF-GFS forecast of snowfall in the metro area today…a much juicier storm than the last two over the metro area:
