A mix of sun and high clouds highlight our Friday weather forecast with afternoon high temperatures today cooler than yesterday into the mid 80’s. The Wenatchee Valley tied a record high temperature Thursday at 95 degrees.
Pacific high pressure will strengthen on Saturday bringing sunny weather conditions to Northcentral Washington and warmer temperatures with highs tomorrow around 90.
Very warm temperatures will continue into Sunday as the Eastern Pacific ridge builds inland. Look for high temperatures on Father’s Day to reach the lower to mid-90s across Northcentral Washington, which is roughly 10 to 15 degrees warmer than normal for this time of year.
The weather pattern becomes more zonal on Monday as the upper level ridge of high pressure flattens and a weak weather system passes to our north. Expect modest cooling and westerly winds to pick up a bit Monday with sunny skies and high temperature near 90 degrees.
Forecast confidence continues to increase that a more meaningful weather pattern shift is shaping up for the middle of next week as a robust Gulf of Alaska trough moves through the Inland Northwest. An associated cold front is likely to bring strong and gusty winds along the lee of the Cascades and the Columbia Basin. Timing and strength of this frontal system is still a bit uncertain, but looks like it may have the potential to increase fire weather concerns. This pattern shift will also bring considerably cooler temperatures. The change begins on Tuesday with sunny skies and high temperatures in the lower 80’s.
The gradual cool down will continue on Wednesday and Thursday under sunny skies, Wenatchee Valley afternoon temperatures will top off in the lower 80’s Wednesday and upper 70’s on Thursday. Overnight low temperatures in the mid 50’s.
Hope everyone enjoys the weekend and especially on Father’s Day Sunday!
