Light snow showers Monday overnight - early Tuesday morning, developed a fresh dusting of snow for much of the Portland metro area. Very little total precipitation is expected Tuesday - Thursday morning, however any showers that form could bring icy travel problems. Most hours through the period will be dry until a Thursday afternoon cold front arrives, bringing likely rain and ending the cold Arctic blast.
If showers develop, temperature profiles would produce the following precipitation:
Tuesday afternoon & evening: Light rain or sleet showers
Wednesday morning: Light freezing rain (odds favor dry weather)
Wednesday afternoon: Rain showers, above freezing temps (odds favor dry weather)
Thursday morning: Freezing rain (again, dry weather may hold)
Thursday afternoon: Rain likely, up to .25" with highs near 40 degrees.
Heaviest snow falls in the Coast Range
