SEATTLE – Seattle is bracing for a heat wave this week. Highs on Tuesday will reach at least 88 degrees. The blistering heat could persist into Thursday. Communities near the Cascades and across the South Sound could wind up in the mid 90s!
Yesterday, Sea-Tac reached 90 degrees. Thankfully, we’ll get a break from the heat today. This afternoon, highs will land in the mid to upper 70s for many under mostly sunny skies.
Due to a ridge of high pressure creating what’s called a ‘thermal trough’ near the surface, temperatures will spike on Tuesday to the upper 80s.
When it comes to fire danger, a Red Flag Warning is posted for much of Eastern Washington from 1-11 p.m. today due to gusts to 40 mph coupled with low relative humidity levels. Here on the west side of the state, the risk of fires will be heightened between Tuesday and Thursday.
A Heat Advisory is posted for Puget Sound on Tuesday and Wednesday. We’ll let you know if it gets extended to Thursday as well.
Cooler weather returns to the region next weekend.
Take good care, …
