Experienced a very active day out there today with strong thunderstorms erupting over the San Bernardino Mountains, and dropping upto 3 inches of rain around Big Bear Lake. Showers and thunderstorms will continue to taper off through tonight as we lose our daytime heat with lows in the 40s. Moisture will decrease a bit on Friday as the deeper plume of moisture shifts further north, but still enough around for widespread convection over the mountains and deserts with scattered showers and thunderstorms likely during the afternoon. A tad warmer tomorrow with highs in the upper 60s. Any thunderstorms that develop may produce torrential/flash flooding rains, frequent lightning, gusty winds, and hail; always head indoors when thunder roars! Moisture will continue to decrease over the weekend, with just a few isolated afternoon thunderstorms possible. Warmer for our last summer weekend as highs top out around 70 degrees. The low responsible for this active weather will meander back into our region Sunday & Monday, bringing an increased chance for showers and storms, ending next Tuesday as this system finally exits the region.
