Warm and dry weather conditions will persist as high pressure remains anchored over the Pacific Northwest. Sunshine will be filtered through thin high clouds but overall, we should see temperatures 5-6 degrees warmer than Wednesday. Winds will remain light and variable today with speeds under 10 mph.
Northcentral Washington weather forecast for today calling for sunny skies with afternoon high temperatures in the lower to mid-70’s.
Friday we begin to see a shift in the jet stream over the Eastern Pacific and Gulf of Alaska as our resident flat ridge of high pressure begins to amplify northward into south-central Alaska. The main weather impacts on Friday will be to flatten the ridge so overall, tomorrow will be another dry, sunny and unseasonably warm day with highs in the mid to upper 70’s. The most noticeable change Friday will be an increase in winds late in the afternoon and evening as a lee-side surface low deepens. Strongest winds Friday night will be found through the Cascade Gaps and across the Columbia Basin where wind gusts of 20-30 mph are expected.
As we kick off Easter weekend on Saturday, our weather pattern will see a major change as a vigorous cold front drops into the region from Canada significantly dropping our temperatures and kicking up very strong winds. The Wenatchee Valley will see mostly sunny skies Saturday with northwest wind 10-20 mph and gusty with afternoon highs in the lower 60’s. The Okanogan Valley and Columbia Basin will see much stronger winds on Saturday with sustained winds of 20-35 mph with gusts of 40-50 mph possible. These strong winds could result in patchy blowing dust and increased risk for fire spread through areas of dry, dead grasses.
On Easter Sunday, the weather will settle down considerably behind Saturday’s cold front. Weather models are showing a very strong ridge of high pressure building once again over the eastern Pacific into Alaska. However, Sunday’s weather will remain cool with sunny skies and temperatures in the upper 50’s to near 60 degrees.
By Monday and continuing into Wednesday temperatures begin to slowly moderate as the upper level ridge drifts slowly eastward. Expect mostly sunny skies each day with afternoon high temperatures in the lower to mid-60’s on Monday, middle to upper 60’s on Tuesday and warming into the upper 60’s to near 70 degrees on Wednesday.
