WINTER STORM WARNING BEGINS AT NOON ON THIS THURSDAY

By Rod Hill on 2021-02-11


The combination of two winter storm fronts will deliver accumulating freezing rain, sleet and 
snow in downtown Portland Thursday night, Friday and Saturday.  A 3rd front Sunday night 
will bring possible warming to our region, but it’s too early to tell when the threat of winter
weather will end. 

Portland will see slowly dropping temperatures this afternoon with freezing weather and icy 
roads likely by early evening if not before.  Gusty east winds are already blowing near the gorge
and Troutdale and Gresham report an icy mix of precipitation at this hour.  A hard freeze in the
20s tonight with sticking snow and possible ice at times across the Portland metro. Some areas
could see 4” of snow on the ground by Friday morning, but precipitation totals will be scattered
and an icy mix will limit snow potential overall. 

Friday morning snow showers will turn into a steady snow during the day as the 2nd storm front
approaches.  Much of Portland is at risk to see hours of freezing rain and or sleet Friday night
into Saturday morning.  Ice accumulations of 1/2” or more followed by snow showers during the day
would make for very difficult travel.  

All total, significant ice accumulations and pockets of 8” of snow on the ground or more is likely in our local
Portland area through the day Saturday. 

East winds near the gorge gusting 45-60 mph have a Blizzard Warning in place for the west gorge. 
Salem and the coast will likely see above freezing daytime temps but an icy and snowy mix at night. 

Coldest metro temps through Saturday night near 25 degrees, but daytime highs Friday and Saturday
may stay shy of 30 degrees with gusty east winds.
