The week ends warm and muggy with a greater chance for monsoon storms thanks to an influx of moisture filtering in from the southeast. This addition will also bump up humidity levels resulting in muggier, tropical-like conditions into the weekend.
While thunderstorms over the next couple of days will be isolated, chances for activity looks greater in the southeastern pocket of our county, including neighborhoods like Mount Laguna, Campo, and Ocotillo Wells.
Rapid downpours, flash flooding and lightning will be the main threats. Depending on how westward monsoon clouds extend, valley communities could encounter pop-up showers. Activity will peak on Friday and Saturday afternoons before diminishing on Sunday.
Daytime highs will continue to drop in the coming days but with a rise in humidity levels, it won't feel like much relief.
Drier air moves in early next week before another surge of monsoonal flow Wednesday.
