Temperatures will start to cool out west today, but remain above normal across the central and eastern districts, with some south- central AZ lower desert locations seeing tripple digits again today. Further cooling is expected this weekend region wide, thanks to a dry cold front, with temperatures falling below normal. This cold front will bring breezy to locally windy conditions to the region. Gusts of 20-30 mph are expected across south-central and eastern AZ this afternoon and evening. Gusts in excess of 40 mph are possible across western Imperial County, otherwise gusts of 25-35 mph are expected across SE CA and SW AZ. The gusty winds will continue through early Saturday morning across SE CA and SW AZ. Gusty winds (20-25 mph) are expected Saturday afternoon and early evening across the eastern AZ higher terrain. MinRHs will be in the 15-25% range, with overnight recoveries in the 30-60% range. ...Thunderstorms imply gusty winds...
