More unsettled weather, this time in the form of scattered thunderstorms and showers, impacted the region this week - also bringing snow to the higher elevations.

A cutoff low pressure system moving between Point Conception and the Great Basin to the northeast throughout the week, brought periods (sometimes bursts) of wind, rain and thunderstorms to much of the region - primarily on Thursday. Pre-frontal bands of moisture began arriving in Southern California late Wednesday night, ahead of more organized thunderstorm activity which lasted throughout Thursday. Showers tapered off Thursday evening across the region, with less remaining instability bringing light rain to parts of the region on Friday.

Due to the localized burst-like thunderstorm activity on Thursday, precipitation totals varied considerably; from as high as 0.83 inches in Pinon Hills, to just 0.05 inches in Anza. The majority of WeatherCurrents stations received totals between 0.3 and 0.7 inches by Friday evening. Warmer, drier weather is anticipated for the weekend as offshore flow develops. In addition, cooler and potentially wet weather are possible late next week.

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