A moist southeast flow continues into Southern California with scattered showers and thunderstorms likely through Wednesday, drying through the end of the week as a southwest flow develops. Thunderstorms dropped around a quarter to half an inch of rain again across some portions of the San Bernardino Mtns today, while other areas stayed bone dry. Even a couple of severe cells firing off to our south over Riverside & San Diego Counties. Such is the world of monsoon season! Activity will wind down this evening with an isolated shower or thunderstorm possible overnight, with lows in the 50s. Expecting a fairly active day tomorrow with scattered showers and thunderstorms firing up by around noon, continuing into the afternoon. Tuesday will likely be our most active day of the week with storms capable of producing heavy rain, strong & gusty winds, frequent lightning, and hail. Head indoors if a thunderstorm approaches your area. Another benefit of the monsoon flow is cooler temperatures as highs drop into the mid-70s the remainder of the week. Unfortunately, a pesky trough of low pressure will push into the West Coast later this week, ushering in a drier southwest flow and temporarily pushing monsoon moisture east of us, but likely to return at some point next week!
