Hot weather has moved in as high pressure has set up shop over the western US. The clockwise motion of air currents around the center of the high is funneling hot, dry air in from the northwest. You may not find much relief at the beach, either. Compressional heating, as well as a lack of marine layer, which will be kept at bay during the overnight hours, will extend the hot weather into the ordinarily-cooler coastal areas.
The heat wave will peak on Friday, with highs in Studio City around 98. The warmer areas of the Valley could see highs approaching 105, and these temperatures will sustain through Saturday as well. We'll start to see the heat wave break on Sunday as a low pressure trough begins to push the high to the south. By Monday, the marine layer will be able to re-assert itself, and our temperatures will get a little closer to normal. Expect highs in the upper 80s by midweek. Onshore flow may even allow some low clouds and fog to form in the valley during the morning hours, though this will dissipate by midday, giving way to mostly sunny skies.
Some models are showing a return of the high pressure ridge late next week, so there is a possibility we could see more heat by next weekend. Another interesting component to the long term forecast will be the leftovers of Tropical Store Kristy, which will be in the neighborhood. Forecasters are keeping an eye on what curve-balls that might throw us.
