The heat is here to stay for a little bit longer, coupled with monsoonal moisture and isolated thunderstorms.
We will start out the week mostly sunny, but as you look east, we will see towering clouds as thunderstorms begin to develop. Monsoon thunderstorms will bring the risk of heavy rain and flash flooding, so stay vigilant to the changing conditions.
It looks like dynamics will favor isolated thunderstorms in the afternoon and evening through Wednesday, at this point no warnings or watches have been issued.
Peak activity will be over the mountains and deserts, but a few storms could move west into the valleys and potentially all the way to the coast. The best chance for storms to travel outside of the mountains westward will be on Monday.
A storm system to our north will bring a much needed cool down, temperatures will drop below average Wednesday through Friday. The air will become drier, helping to provide more comfortable conditions. The pattern shift will help provide some relief from the ongoing heat from the coast to the deserts.
Near the coast the marine layer will return each night and morning with patchy clouds, but as cooler air moves in late in the week it'll help to deepen the marine with lingering clouds into late morning and traveling farther east into our valleys.
