General Discussion: An approaching warm front will push another system into the Cascade Mountains tonight. The freezing levels will be the determining factor on how much snow and or rain we will receive. Hopefully the bulk of the precipitation, at least on the upper mountain, will be snow.
Long-term: Periods of snow, mixed rain and snow will continue for the first part of the week. The second half of the week appears to dry and fairly inactive. The next storm for potential snow will enter the scene sometime next weekend.
24hr Accumulative Precipitation Totals Starting at Noon Today:
“Water by midnight= .25-.5
“Of additional water by 4am= .10
“Of additional water by 12pm= .10
24hr (12pm-12pm) Inches of Water = .75
24hr (12pm-12pm) Inches of Snow = 8-10”
Trend and Timing:
Snow should begin falling this afternoon. With the aid of the cold air from the east, snow should continue through most of the night. There will be a chance of some freezing rain turning to rain sometime early tomorrow morning as the warm air arrives. The precipitation will shift to intermittent showers tomorrow.
