Monsoonal moisture over the region managed to squeeze out a few showers during the early morning hours of Friday across parts of the inland valleys.

Mostly cloudy skies had covered the region on Thursday, as a thick layer of mid-level clouds had largely suppressed any chances of significant convection over Southern California, diminishing any chances of thunderstorms. An additional wave of moisture did however arrive to the region after midnight, producing light showers in many areas west of the mountains between 2 and 3 AM. Nighttime temperatures remained warmer than average as they had done since the beginning of the month, a side-effect of relatively high humidity associated with the monsoonal moisture. Precipitation totals are not significant, with most locations west of the mountains receiving less than 0.10 inch. The greatest total was 0.25 inches in East Highland (courtesy of Peter Michas), while parts of the Temecula Valley and surrounding areas were some of the only other locations in the WeatherCurrents network to record measurable precipitation Friday morning. Temecula was the slightly wetter of the bunch with 0.08 inches recorded there, as well was 0.07 inches in nearby Temecula Valley Wine Country (courtesy of Jim Sappington). San Jacinto was the only eastern valley location in the WeatherCurrents network to record rainfall, and even that amounted to only 0.01 inch.

Cumulus associated with the monsoonal moisture had already mostly cleared out of the region by mid-morning Friday, having moved further north to bring thunderstorms to the Great Basin and Sierra Nevada mountains. Following a brief drying out period, another round of monsoonal moisture was forecast to bring yet additional chances of shower and thunderstorm activity to the region next week.

Here are the rain totals for the WeatherCurrents network and associates:
