Arctic Invasion this Weekend
An arctic invasion begins Wednesday across the northern plains and upper mid-west with temperatures quickly plummeting to below zero. This arctic airmass continues to move south and east and will arrive in our area Friday morning.
Temperatures will be dangerously cold with 5 above zero to 15 below zero wind chills Friday and Saturday. Actual temperatures will range from the single digits in the mountains to the mid to upper teens in the Tri-Cities. This cold arctic airmass will stick around through the holiday weekend.
Moisture will quickly transition from rain to snow showers with quick accumulations of up to an inch possible around the Tri-Cities, 1 to 2 inches in the higher elevations. Given the nature of the drastic drop in temperature, a flash freeze could cause icy roadways during the day Friday.
The snow showers end early Friday while the arctic chill will stick around through the weekend. Follow the latest Storm Team 11 Forecast on all of the impacts
