The weak weather system that dropped a dusting of snow in the Wenatchee Valley last night is now into Eastern Washington leaving behind a seasonably cool day with some low stratus clouds, high temperatures today in the lower to mid-30’s.
Tonight and most of Saturday appears to be shaping up as a cool but quiet and benign weather period as a sharp upper level ridge transits through. Low clouds and at least patchy morning fog will slosh around the Columbia Basin and valleys with mostly cloudy skies by afternoon with highs in the lower 30’s. Saturday night brings the next chance of widespread but light snow to Northcentral Washington as a shearing mid-level cold front follows the warm front through the area. The whole weather system will be weakening as it passes through so only a trace to 1 inch of accumulation is expected Saturday night with the higher amounts near the Cascade crest.
Cloudy skies for Sunday as well with a 30% chance of rain and snow, highs in the mid 30’s.
An upper level ridge of high pressure will make a brief appearance on Monday with partly cloudy skies and afternoon temperatures in the mid 30’s.
By New Year’s Eve on Tuesday, weather models show a more progressive and active period with several storm systems moving through the Inland Northwest. Cloudy skies in the forecast for Tuesday with a 50% chance of rain and snow then all rain late in the day with afternoon high temperatures in the upper 30’s.
For New Year’s Day, partly cloudy skies are in the forecast for the start of 2020 with just a slight chance for showers with afternoon highs near 40 degrees. Cloudy with a 30% chance for rain on Thursday with high temperatures in the upper 30’s and lower 40’s.
