Clear sky conditions across much of the region this morning with offshore flow aloft. The exception is around Half Moon Bay and down along the Big Sur Coast as a very shallow marine layer remains less than 500 feet in depth. As a result of the offshore winds, temperatures will warm-up quickly this morning and into the afternoon. Maximum temperatures this (Monday) afternoon will warm into the low to mid 70s along the immediate coastline with low to upper 80s across inland areas. Downtown San Francisco has around a 12% probability of exceeding 85 degrees F with southeast portions of the city at around 25%. Places such as Novato, San Rafael, San Mateo, Redwood City, and Gilroy have a 30-50% chance of exceeding 90 degrees F. These temperatures are generally around 5-10 degrees above seasonal averages across the North Bay and Bay Area. It is going to be downright warm this afternoon (and again tomorrow).
