Northcentral Washington will still be under the influence of a shallow ridge of high pressure allowing the feed of moisture and warm air to bring widespread rain showers and mountain snow to the Inland Northwest this morning. At the same time, an approaching low toward British Columbia will bring a warm front through the region today. This will bring increased winds for the Columbia Basin with southerly sustained winds in the upper teens/low 20s and gusts near 30 mph. Cloudy in the Wenatchee Valley today with a 60% chance of misty rain and warm with afternoon highs in the upper 40’s. The increasing warm air will also increase the mid-level snow pack melt and could lead to some local rises on small rivers and creeks.
As the large area of low pressure continues to track through Southern British Columbia and Alberta on Saturday, it will carry a cold front through the region during the afternoon which will make for a very windy weather day in some locations. The wind tomorrow is expected to be the strongest across the Columbia Basin with sustained into the 20’s and low 30’s and gusts reaching into the high 40 mph range. For the Wenatchee Valley, expect a 60% chance of rain with west wind 10-20 mph and afternoon highs unseasonably warm into the upper 40’s to lower 50’s.
We dry out and cool down on Sunday and Monday with mostly sunny skies and afternoon highs falling back down into the upper 30’s.
Another weak weather system moves through on Tuesday with a 30% chance of rain mixed with snow and afternoon high temperatures in the upper 30’s. There is also a 30% chance of moisture on Wednesday and Thursday next week but warmer with high temperatures back up into the mid 40’s to lower 50’s.
