Daytime highs are still continuing to trend down by a few degrees Thursday. The smoke that is in the atmosphere could actually help with that process. Daytime highs across the inland valleys could stay close to the mid to upper 80s while the coastal valleys will mostly be in the 70s. At the coast, the marine layer could influence daytime highs and keep temperatures capped right around the low to mid-60s.
