So called old-timers know, the only time downtown Portland is guaranteed snow is when the air has been below freezing and the east winds have been blowing for days.  In other words, Portland is good and cold long before the Pacific moisture arrives.  The set-up I just mentioned can lead to our big snow storms of a foot or more!

Early Wednesday morning will be our usual guessing game.  The air is chilly but not cold and lowest elevations could be anywhere from 30 degrees and snowy Wednesday morning to 35 and raining or a rain-snow mix that does not stick. 

Plenty of moisture will be available, so I can guarantee a wet start to your day.  If the east winds out of the Gorge hold our temperature near freezing, the metro will see a classic snowfall of several inches over several hours. 

The afternoon will warm, the rain will fall and the excitement of snow will soon be gone.  Please set your alarm, get up early, turn on KGW's Sunrise show and get the latest weather. 

If you live in the hills, you may wake up to 4 inches of snow before you turn on the coffee pot!

Like you, I will get up and see what is happening and then record the snow or rain into the record book.
