Heat Slowly Ramps Up
The big western ridge will wobble back toward California this weekend, settling in for the long haul. Highs had leveled off to close out the week but will head upward through Monday-Tuesday. Coastal temps will average 10ºF above normal while inland temps will soar to 20ºF above normal. It looks like temperatures will stay pretty toasty through mid-week and then cool down into next weekend. There is still some question as to how hot it will get on the coast. The latest trends have been hotter for Monday/Tuesday.
The other big wild card in the forecast will be tropical moisture. It looks like a yet-to-form tropical cyclone may push up Baja California toward the end of the week with its moisture reaching southern California—and perhaps Central California Thursday/Friday. This could mean anything from a few high clouds to thunderstorms. We will be closely monitoring.
AIR QUALITY: GOOD to MODERATE
