Mainly dry weather will persist across the Inland Northwest today as a broad upper ridge of high pressure over the Eastern Pacific builds inland. Mostly sunny with a gradual warming trend for our Friday with high temperatures this afternoon in the lower 40’s.
For Saturday and Sunday, much of Northcentral Washington will see partly cloudy to mostly sunny skies with afternoon high temperatures in the lower to mid-40’s on Saturday and in the upper 40’s for Sunday. With mostly clear skies at night and radiational cooling, we could also see some patchy morning fog both Saturday and Sunday morning but with the March sun angle any fog should burn off rather quickly.
Starting Monday and for all of next week, strong high pressure aloft will promote stable and dry weather with temperatures back to where we should see them for this time of year. Under sunny skies on Monday and Tuesday, expect afternoon high temperatures to reach into the low to mid 50’s. By next week, our normal high temperature will be 55 degrees. A warm southwest flow aloft will continue to bring us mild mid-March temperatures on Wednesday and Thursday with partly cloudy skies and high temperatures in the mid to upper 50’s and overnight lows in the mid 30’s. A main concern through end of the workweek will remain a slow but steady melt of low elevation snow resulting in ponding of water in poor drainage areas, some field flooding, and thawing/softening of roads.
