The weather pattern for the next 2 days looks very March-like, except for unseasonably cold temperatures. A very cold upper level low will move over Northcentral Washington today, which will make for a very unstable atmosphere. Coupled with the warming March sunshine, we will have a decent amount of convective shower activity this afternoon and evening. The showers will all be in the form of snow or graupel. Expect mostly sunny skies this morning turning mostly cloudy by afternoon with a 30% chance of light snow shower activity, high temperatures in the lower 30’s.

For Saturday, the low is pretty much stationary over the Coeurd`Alene, Idaho area but the cold air aloft will move mainly south and east of our area. Look for morning fog on Saturday giving way to mostly sunny skies by afternoon with highs once again in the lower 30’s. Temperatures will remain cold, about 15 degrees below normal.

Sunday, a short wave ridge of high pressure will move over Northcentral Washington through Monday afternoon with mostly sunny skies, dry conditions and afternoon high temperatures in the lower 30’s.

By Monday night, weather models continue to show a moist boundary layer bringing the next storm system our way into Tuesday. We have a 50% chance of snow Monday night and a 30% chance of rain or snow showers on Tuesday with highs in the upper 30’s.

On Wednesday, the low aggressively drops south into Nevada allowing a strong upper level ridge of high pressure to build in bringing mostly sunny skies on both Wednesday and Thursday with afternoon high temperatures in the lower 40’s and overnight low temperatures in the mid to upper 20’s.
