URGENT UPDATE: California is bracing for a dramatic weather shift this week, with rising humidity and severe thunderstorms expected to impact the state. Following a brief period of pleasant fall-like weather, monsoonal moisture is set to surge into California, leading to a sauna-like atmosphere and increased chances for thunderstorms starting Thursday, September 21.
Residents of Southern California can expect discomfort as the humidity climbs, transforming the air into a sticky, muggy condition. The National Weather Service warns that the chance of thunderstorms could reach 10-35% by the end of the week, particularly affecting mountain and desert regions.
As early as Wednesday, the Central Coast, including areas like Paso Robles, may experience temperatures soaring into the 90s and low 100s degrees Fahrenheit. Coastal regions will see slightly cooler temperatures in the mid-80s, while beaches will remain in the high 60s to low 70s.
Fog is forecasted to roll in from Tuesday to Wednesday, creating pockets of mist across the coastline, but the real concern lies in the impending thunderstorms. Officials emphasize a heightened risk of dry lightning, which can trigger fire starts, and brief heavy downpours leading to potential flooding.
In a statement, the National Weather Service cautioned:
“Thunderstorm chances increase significantly Thursday and Friday, with wetter storms likely as more moisture moves in. Be prepared for gusty, erratic winds and the possibility of flooding through the weekend.”
As the humidity rises, California may feel like one large sauna, with thunderstorms potentially producing showers west of the mountains. Residents are advised to stay informed and prepare for rapidly changing conditions.
Looking ahead, temperatures are projected to decrease by Thursday, but the high dew point will maintain an uncomfortable level of humidity. The arrival of the Autumn equinox on September 22 will officially mark the start of fall, with daylight hours shrinking.
Prepare for a significant weather shift in California this week. Stay alert for updates and heed warnings from local authorities.
