Weather 4-10-20


Today will be dry and warm with an abundance of sunshine. An abrupt change in our weather will arrive Saturday morning with the arrival of a strong cold front. North winds gusting to 50 mph or more will channel down the Okanogan Valley into Central Washington on Saturday. Temperatures will remain cooler than average on Easter Sunday followed by a warming trend next week.

Today will be another mild day across the Inland Northwest with temperatures pushing back into the upper 60’s to upper 70’s under mostly sunny skies. The most noticeable change today will come in the form of winds as west to northwest winds pick up late in the afternoon and evening hours. The increase in winds is in response to a deepening surface low in the Columbia Basin as a strengthening weather system approaches from the north. Wind gusts of 20-25 mph will be common across the Central and Eastern Columbia Basin by tonight. Stronger winds are expected to impact the East Slopes of the Cascades, Waterville Plateau, and Western Columbia Basin with local gusts of 35-40 mph expected in those areas.

On Saturday, a strong weather system moves into Northcentral Washington with mostly sunny skies and very windy in the Columbia Basin and Waterville Plateau with steady speeds of 20-30 mph and possible wind gusts up to 50 mph. Dry and windy conditions across Central WA will bring the potential for blowing dust around Ephrata and Moses Lake. Confidence is low exactly what impacts this will have but something that we will be closely monitoring. Not as windy in the Wenatchee Valley tomorrow with a northwest wind 15-25 mph by afternoon and gusty at times with afternoon high temperatures much cooler in the lower to mid-60’s.

For Easter Sunday, the windy weather conditions will subside as the cold front moves east across Southern Canada. Northcentral Washington can expect mostly sunny skies, light wind and normal temperatures for this time of year with highs Sunday around 60 degrees.

Another warming trend begins on Monday and intensifies right through the rest of the week with temperatures on Monday in the upper 60’s warming to the lower and then mid 70’s by Wednesday and Thursday.
