Thursday evening forecast Sep. 3rd

Afternoon temperatures will be warming steadily this week, with potentially record high temperatures in several locations during the three day holiday weekend. There is a high risk for heat illness along with heightened fire weather concerns during this time. Temperatures will turn cooler but remain several degrees above normal Tuesday through Thursday.

Friday sunny skies will prevail across the region thru the afternoon. The ridge of high pressure will strengthen and bring warmer temperatures with highs well above average in the mid 70s to mid 80s along the coast and 90s and 100+ inland.

Temperatures continue to increase with the height of the heatwave expected on Sunday. An Excessive heat warning is in effect for the valleys and mountains from Friday morning until Monday night as highs are in the triple digits. The coast has an excessive heat warning from Saturday morning until Sunday night with highs in the 90s. This kind of heat can be life-threatening and people are urged to use common sense, keep hydrated and stay out of the heat and in air-conditioned locations as much as possible. Overnight lows will remain very warm as well over the weekend with readings in the 70s to lower 80s for many areas, except may not fall below 90 degrees in some breezy foothill areas Saturday night.

We expect to start seeing some relief on Tuesday, but staying above average.
