FORECAST HIGHLIGHTS
DRY THURSDAY: One last day with a cool morning and hot afternoon thanks to low humidity
SPOTTY DOWNPOURS FRI/SAT: Rain won’t be widespread
FORECAST
After a record morning low of 67°, we warmed up to near 100° Wednesday afternoon. The temperature swing was courtesy of dry air.
THURSDAY
Expect another cool, but not quite as cool, morning. It’ll be near 70°. Then, quickly warming to near 100° in the afternoon. Once again, it’ll be a dry heat. There’s a small (10%) chance for a stray afternoon shower. Otherwise, humidity will climb back by Friday through the weekend.
SPOTTY DOWNPOURS
Friday and Saturday bring our best opportunity for pop-up showers -- and even then the odds aren’t great (20-30%). Do know that temperatures will remain hot and humidity levels are forecast to increase.
