What looked like the possibility of an epic and historical snowstorm just last week is increasingly looking like a dud. A cold air-mass has its grips across the Pacific Northwest today and will remain in place until Tuesday afternoon. Meanwhile, a warm front and area of low pressure is headed our way. Recent computer models have shifted this low to the north near Vancouver Island. A more northerly trajectory puts us in the warm sector much sooner and limits the amount of frozen precipitation we will see. Here’s how I see things breaking down.
Today: Partly to mostly sunny at times and cold. Highs in the upper 30s
Tonight: Mostly clear and cold. Lows in the upper 20s.
Tuesday: PM Snow for Portland/Vancouver anywhere from 1-4 pm depending on the speed of the storm which looks like its picking up speed. By 6 pm (evening commute) we could see a brief period of freezing rain before warmer air filters in and changes the frozen precipitation into all rain.
: Rainy and warmer with highs in the 40s. The Gorge is the big wildcard right now where the colder air will last for longer. We could see a much longer period of snow or freezing rain depending on the storm’s track.
Meanwhile the National Weather Service in Portland has issued a Winter Storm Watch for the entire Portland/Vancouver area for Tuesday afternoon and evening.
