More storms lined up for this week

Futurecast Snow Accumulation Thru 01/23/18

Computer models continue to suggest our active weather pattern will continue this next week, and Mother Nature appears to be following along. Our next round of stormy weather will begin Sunday evening and last into early afternoon on Monday.

Some model guidance is suggesting we could see a few inches of snowfall by Monday morning, although, I'm expecting about a half of an inch or so. The graphic below shows the 21 different members of NCEP Short-Range Ensemble Forecast system, the mean between the models is suggesting we could possibly see closer to 2-inches of snowfall. Notice the highlighted model, it shows closer to 5-inches, wouldn't that be nice? We could use a good snow storm here in the valley.

Why so different? Most of the SREF models are forecasting colder temperatures than what we'll likely see here in the Treasure Valley as the front rolls in. Even though temperatures will eventually get cold enough to see all snow in Boise, by the time it happens, it's expected that much of the moisture will have moved out. Although it's not a major storm system, travel will likely be difficult Sunday night and Monday morning.

A Winter Weather Advisory has been issued for the West Central Mountains, Owyhee Mountains, and the Upper Weiser River zones by the National Weather Service, from 5 PM Sunday through 11 AM Monday. The advisory is for total snow accumulations of 2 to 4 inches with localized amounts up to 10 inches in those locations. Be prepared for reduced visibilities and snow covered roads if traveling during that time.
