|SYNOPSIS FROM THE SAN DIEGO OFFICE
..Heat Wave Continues Inland with Excessively Hot Conditions Over the Deserts... Very hot conditions will continue across the deserts this week under a strong high pressure ridge. A shallow marine layer will continue to moderate conditions along the coast and into the western valleys, along with areas of nocturnal clouds and fog, lingering into the afternoons at some beaches. It will be a little cooler west of the mountains to end the week as onshore flow increases, extending the marine influence farther inland. The foothills and lower coastal slopes will remain seasonably hot through the weekend. Inland temperatures closer to seasonal averages could return towards the middle of next week.
SYNOPSIS FROM THE PHOENIX OFFICE
There will be a subtle decrease in temperatures today but still extremely hot. In fact, many locations will be at or near record levels. There will also be a decrease in thunderstorm activity over Arizona as well. Temperatures lower some more on Thursday, but humidities will be higher and still excessively hot. Expect no significant cooling through Sunday. Anticipate a modest cooling trend Monday and Tuesday.
