We finally experienced a more active day around the San Bernardino Mtns today in regard to the monsoon flow. A large MCC (Mesoscale Convective Complex) turned surface low/easterly wave last night over Arizona and helped initiate scattered convection around our region. Unfortunately, most of the heavier rain fell over Barton Flats, where they picked up nearly a half inch, with a few hundredths recorded in portions of the Big Bear Valley. Not to worry, this is only the start of what will hopefully be an active week of monsoonal thundershowers. In the meantime, expect parly cloudy skies tonight with lows tonight in the 50s. We will still have enough mid & upper level moisture around tomorrow for a few isolated afternoon showers, maybe a rumble of thunder. High pressure will also strengthen through Saturday, pushing daytime highs back into the upper 80s. As this ridge weakens and shifts further east, additional moisture will be drawn into the area, bringing a better chance for mainly afternoon & evening showers and thunderstorms, especially Sunday into next week. This will also bring a gradual cooling trend as temperatures return to normal by the middle of next week!
