A low pressure system with tropical influence brought sporadic thunderstorms to the region beginning Wednesday this week, continuing into early Thursday before maintaining a marine layer influence over the region instead.

This storm was the same low pressure system responsible for rain earlier this month. That system had traveled south of California into the Baja California Peninsula, before returning north again with a tropical influence. The increased humidity and cloud cover associated with the storm has kept temperatures very warm for this time of year, when the weather is usually cooling down instead.

Twelve of the eighteen currently active WeatherCurrents stations recorded rainfall since Wednesday. Precipitation totals were as high as 0.41 inches in East Hemet, while some communities did not record any measurable rainfall. The instability associated with the storm brought thunder and lightning beginning late Wednesday night. As the thunderstorm activity of the low made its way north Thursday, a tropical marine layer has formed over most of Southern California west of the mountains. It has produced measurable drizzle in some locations.

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