We had a few thunderstorms in and around the region again today, with the heaviest to our south over San Diego and Riverside Counties. Monsoon moisture will continue to stream northward with better instability forecast on Monday and Tuesday. This should lead to deeper convection across our area, i.e., more widespread thunderstorm activity. Expect partly cloudy skies through Monday morning, becoming mostly cloudy by afternoon with scattered showers and thunderstorms likely. Warm and humid with a high near 80°, southerly winds 5-15 mph at times, gusty near any storms. Showers and storms will remain fairly widespread through Tuesday, becoming more isolated on Wednesday, before ending on Thursday. Any storms that develop may be capable of producing heavy rain, gusty winds, frequent lightning, and hail. Gradually cooler throughout the week as highs drop into the mid-70s with overnight lows generally in the 50s. A trough bumping up against the West coast will push monsoon moisture off to our east by the end of the week, with a drier, more stable environment returning in time for the big Labor Day weekend. Temperatures will remain close to average through the holiday weekend with a possible return of monsoon moisture sometime next week.
