Two things are a bit different than I expected today. But first…what worked out perfect…our first “snowy day” in Portland since February 2014.
Pic by Clifford Paguio. Snowy/icy roads are widespread (except where the wind blew the snow off the roads) across the area now. Freeways melted a bit this afternoon with all the gunk thrown on them by ODOT, but they should freeze up again tonight.
The main band of precipitation was a bit later to arrive than I expected, by a few hours and of course most of the snow came from the earlier-than-expected first band of precip.
The other thing that’s a big different is always the toughest to forecast…when warmer air above pushes in and changes the snow to freezing rain, ice pellets, or a wintry mix of the 3. That has already happened so we are mainly done with snow accumulation. As a result the totals are at the low end of my 1-3″ forecast last night. The heaviest snow seems to be from north Portland up through eastern Vancouver…up to 2″ in those spots:
Now that we’ve transitioned to mainly freezing rain, roads are going to really get messy with temperatures remaining below freezing overnight. Note all current metro area temps (and down into the valley) are below freezing. The only above freezing spots are along the Cascade foothills in Clackamas and Marion counties…about where models said a warmer layer of air would push north.
Expect widespread snow/ice still on roads for the Monday AM commute
More later…we have a newscast right after the Seahawks game in the next half hour or so and I need to get that prepped.
If you have a snow total more than 0.5″, let me know in the comments below.
