Weather 4-7-20


The remainder of the work week will feature dry and unseasonably warmer weather all across Northcentral Washington. Many locations will experience highs in the 60s to 70s Wednesday, Thursday, and Friday. Temperatures will trend a bit cooler over the weekend, and the chance for showers will return to the mountainous portions of the Inland Northwest.

The combination of low pressure passing through the Canadian Plains and high pressure building on the Pacific Northwest Coast will create a tight pressure gradient across our viewing area today and will result in breezy weather. Winds have already picked around Wenatchee, Entiat, across the Waterville Plateau, and into Ephrata this morning. Breezy winds will expand across the entire Columbia Basin by this afternoon with gusts to around 25 mph. By late afternoon and early evening, wind gusts are expected to ramp back up into the 30-35 mph range as the late day drainage winds align with the gradient driven winds. In addition to the Wenatchee River Valley, Waterville Plateau, and Entiat area, hi-res models show a burst of northwest winds of similar speeds coming down the Methow Valley and spilling toward Grand Coulee.

The Wenatchee Valley can expect partly cloudy skies today with a northwest wind 10-20 mph with gusts to 25 mph, afternoon high temperatures in the mid to upper 60’s.

High pressure strengthens over the Northwest for Wednesday and Thursday promoting light winds and a strong warming and drying trend. Afternoon highs will warm into the upper 60’s to near 70 degrees on Wednesday and upper 60’s to the lower 70’s Thursday under mostly sunny skies.

The upper level ridge of high pressure will keep the region mild and dry into the end of the week on Friday with mostly sunny weather and afternoon highs in the lower 70’s.

A Canadian trough of low pressure will drop down into Northcentral Washington on Saturday bringing a few more clouds and cooler weather with highs on Saturday in the mid 60’s and lower 60’s on Sunday.

Another area of high pressure moves in on Monday with mostly sunny skies and afternoon highs in the mid 60’s.
