Tonight’s system will bring light rain showers to the Lewiston / Clarkston through Tuesday.  With temperatures below freezing, the Spokane/ CDA area should receive about ½ of snow, mixed with areas of freezing rain at times. Travelers should prepare for a slippery Tuesday morning drive along I-90. The Palouse can expect rain mixed with snow without much accumulation. Areas north of Spokane and east of Orofino & Grangeville can expect all snow.

A better chance of rain reaches the area THURSDAY NIGHT.  The valley can expect about ¼ inch or less with rain changing to light snow as temperatures drop during the afternoon. THE WEEKEND should be cool and dry with morning lows in the 20s and highs in the upper 30s.

Wintry Mix tonight - slippery drive tomorrow

A mix of light rain, light freezing rain or light snow is expected across the Interstate 90 corridor from the West Plains, into the Spokane and Coeur d'Alene areas and east to Lookout Pass. Any precipitation amounts will be quite light but it only takes a very small amount of freezing rain to create hazardous driving conditions. Snow will be more likely in the Deer park and Sandpoint areas. Rain will be more likely for the Pullman and Lewiston areas.
