On Wednesday, San Luis Obispo County could see its first rainfall since April — and that’s not all.
Thunderstorms are also in the weather forecast into the evening, according to the National Weather Service.
The forecast could peter out, however, as there’s only a 20% chance of any precipitation, according to the Weather Service.
The system of subtropical moisture will produce high-level clouds, according to a Twitter post by local PG&E meteorologist John Lindsey.
Lindsey also noted in his post that the system is mainly going to be in the eastern regions of San Luis Obispo County.
The thunderstorms, while perhaps bringing much-needed moisture to the drought-parched area, mean there’s an elevated wildfire risk, the Weather Service warned in an advisory on Tuesday.
Dry lightning strikes could spark fires in the region, which hasn’t seen rain in months, the Weather Service warned.
Temperatures for the rest of the week are expected to continue to be hot, especially in the North County.
Paso Robles will likely see the mercury rise into the high 90s on Thursday and Saturday, while reaching a predicted 93 degrees on Friday, according to the Weather Service.
San Luis Obispo is expected to cool off a bit as the week continues, seeing temps fall into the low 80s by Thursday and through the weekend.
An upper-level low centered along the immediate shoreline of the Central Coast will push subtropical moisture over Central California on Wednesday. This system will produce high-level clouds and a chance of showers & thunderstorms, primarily in the eastern regions of SLO County. pic.twitter.com/JKzU1mUSBC
