Highs will range from the 70s at the coast to the lower to mid 90s in the valleys in the valleys which is about 10 degrees above normal. RH recovery was only fair in a few desert-adjacent areas last night and readings are only around 20-30% early this morning. Expect minimums to reach the…

FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA Monsoonal moisture will be increasing through midweek, providing the fuel for scattered shower and isolated thunderstorm development over most of the area. Moderate easterly flow should limit the flooding potential, and clouds may limit instability at times as well. As steering flow weakens, and moisture decreases aloft later on Wednesday…the chance for stronger, slow moving thunderstorms with heavy rain and possible flash flooding will increase into Thursday. FLASH FlOOD ALRTS IN AREAS OF INLAND…
