PORTLAND, Ore. (KOIN) – In what feels like a never-ending winter, this first weekend of March starts with a chance for snow in the greater Portland and Vancouver hilltop areas. A winter weather advisory is in effect Saturday early morning until noon targeting elevations above 700 feet.

What’s the probability Portland will actually get snow? The latest examination of forecast models show the valley floor will be too warm for snow to stick. You may get snow splatter on your windshield, aka chunky rain. However, under a more intense band of precipitation you could see snow accumulate in your yard. Your snow meter pegs the “likely category” if you live above 700′ to 1,000′ feet. Take a look below to view potential snow totals in your city.

Rain showers continue into the afternoon with highs in the low 40s. Possible thunderstorms from the coast to valley too! BTW – Portland hasn’t had a high above 50° since Feb. 21!

Be aware there is a Winter Storm Warning for the Coast Range Saturday until 4pm with 1-5 inches of snow possible over Sunset Summit. Potentially 6″+ above 1500′ feet. Hwy 26 is already covered in snow at the Sunset Rest Area.

Windy and snowy Saturday for the mountains, so it’s a typical winter day at Mt. Hood. Sunday looks decent for skiing.
