Through the day mid and high level clouds will be streaming into the region from the southeast as monsoon and subtropical moisture usher into our region around a high pressure centered over the Four Corners. The marine layer on the other hand will gradually become shallower tonight and will not be an issue for fireworks viewing, but a few mid-level clouds may hover close to where the fireworks explode.
Due to the subtropical air moving in, this afternoon will not only be hot, but humid as well for outdoor activities inland, even warm at the coast. This also means temperatures will be comfortable this evening for the fireworks in the low-70s at the coast and mid-70s inland.
The bigger issue this afternoon and evening is the slight chance for isolated thunderstorms in the mountains. Beginning between 2 and 3 this afternoon cumulus clouds will start to tower with lightning possible into the night, the threat ending by midnight. A stray light shower may be able to make it over the mountains and move over inland valleys and the coast. The atmosphere is quite dry, however, so most of us will just see increased clouds and the potential for virga (rain that doesn’t hit the ground), with a slight chance for a rumble of thunder.
For those heading to the beaches, be aware of high surf and strong rip currents today through early next week. Remember, if caught in a rip current to swim parallel to the shoreline.
