After a Springlike weekend, Washington and Oregon head back into winter for the start of the workweek. A cold front brings early Monday rain, mountain snow and cool temperatures to the Pacific Northwest.
Coastal and valley rain will start just in time soak the roads for morning commuters. The rain, tapering off into Tuesday could total a half to an inch. Mountain snows appear to be in the 3-6 inch range around 2,000 ft. Higher elevations in the Cascades could see up to a foot of snow. The Olympics will only see 3-4 inches of snow.
The snow heads for the Northern Rockies for Tuesday and Wednesday.
Temperatures return to average for this time of year, around 50 near the coast. The weather remains unsettled through the week.
High pressure was in control for the weekend providing tons of sun. Offshore breezes took the February chill out of the air. The dry air warms as it slides down the slopes of mountains, called compressional heating.
