A Severe Thunderstorm Watch is now in effect until 3am ahead of a line of strong to severe storms moving into the area. Be ready for rapidly changing conditions this evening.
The heat advisory has been extended until 7PM given plentiful heat indices still at 110° or beyond.

The week ahead gets off to a hot start as westerly winds keep the seabreeze close to the coast for much of the day, driving highs into the mid-to-upper 90s on Monday afternoon. Mix in low-70s dewpoints and heat indices will peak above 105° in the afternoon. From there, a thunderstorm complex will approach the area from the northwest, but it should get here toward the evening and be in a weakening phase as a result. A strong wind gust or two can’t be ruled out, though, especially the further inland you are.
