Moe Low Snow Expected!

We had showers moving across the area this morning but the rain from the next system is already moving onshore. As of 7am this morning, ODOT was still reporting snow flurries up at the higher passes though this should turn over to rain soon as the snow level will temporarily rise today and this evening. Later this evening we can expect some moderate, occasionally heavy rain to develop as the front itself works its way through and the usual winds, gusting to 35 inland and 55 along the coast. While the rivers will surge up about 3’, they will still crest several feet below Action Stage. After the front goes through tonight we will continue to have showers into tomorrow when the colder air settles in causing an increase in showers which will turn to snow in the Coast Range (1-3”) as the snow level drops to between 500-1000’ by tomorrow evening. The showers will continue into Wednesday with the snow level hovering down around 500’ still (another 1-3”), possible even lower over in the valley with colder air spilling in through the Gorge. Thursday we should see decreasing shower activity but with the lower snow levels, snow showers are still possible in the passes Thursday morning. High pressure is expected to build in by Thursday afternoon to help dry things up a bit through Sunday.

Advisories, Watches and Warnings

A Small Craft Advisory is in effect until noon today when a Gale Warning takes effect thru 6am Tuesday.

The Winter Weather Advisory and High Wind Watch for the coast and Coast Range has expired. The High Wind Watch may be reissued later today as the winds are expected to get close to warning criteria and the previous Winter Weather Advisory has expired but I would expect another to be issued later this evening for tomorrow’s expected snowfall activity.
