An upper low will form a cutoff circulation over northern California Monday, moving southward to between Southeast California and Arizona Monday night into Tuesday. This will initiate a period of gusty north or northeast winds, depending on where the upper low sets up. If the low moves over Arizona, that location will favor a Santa Ana event with stronger northeast winds, and compressional warming over the valleys and possibly coastal areas. The dry and breezy conditions are expected to persist through early Wednesday, with cooler conditions expected later in the week.
