HISTORIC AND DANGEROUS HEAT WAVE EXPECTED THIS WEEKEND AND WELL INTO NEXT WEEK.
As high pressure remains anchored off the Pacific coast, dry and warm winds will once again blow across central and eastern Washington today. Northcentral Washington weather for today will be sunny, windy and hot with afternoon highs in the mid 90’s. Localized gap winds in the Wenatchee, Entiat, Chelan, and Vantage areas are expected to blow in the 15 to 20 mph range with gusts to 30 mph prompting the issuance of a Red Flag Warning for portions of central Washington today from 1:00 p.m. to 9:00 p.m.
A weak upper level disturbance will dig down through Montana on Thursday which will continue to bring us a northwest breeze 5-15 mph tomorrow with high temperatures once again in the mid 90’s.
Our highly advertised heat wave will build into Washington on Friday, Northcentral Washington in particular. Under sunny skies and light wind, places like Omak, Moses Lake, Wenatchee, and Leavenworth will have a good shot of 100 degrees Friday afternoon.
Saturday through Tuesday, weather confidence remains high that the Inland Northwest will experience a historic heat wave this weekend into next week. As such, excessive heat watches have been issued for the region from Friday afternoon through Tuesday night.
Sunny with possible record-setting heat both Saturday and Sunday with afternoon highs between 105 and 110 degrees.
Both Monday and Tuesday could be all-time record high weather days with sunny skies, light wind and afternoon high temperatures between 110 and 115 degrees.
This heat event raises some concerns. This won`t just be one day in the 100s. Multiple days in a row of these temperatures will make heat illness all the more likely if precautions aren`t taken because the heat will continue to stress the body each day. The heat will unfortunately be bad news for farmers, too. Low relative humidity and no precipitation will worsen the already bad drought.
