Thursday will be another day with off-and-on showers throughout the day with cooler daytime highs, the main change will be the slight chance for afternoon thunderstorms.
As a low-pressure trough moves over California, the Central Coast will have cooler daytime highs mostly from the low to upper 50s. Some areas, including the south coast region, will likely be warmer by a few degrees and stay closer to the low to mid-60s.
Northwesterly winds will continue to be breezy throughout the afternoon. As of 4:15 a.m. Thursday, wind gusts had already reached 16 miles per hour in Santa Maria, and by the afternoon it's possible that wind gusts could reach 20-30 mph.
Weather models are showing that the rain activity over the Central Coast will be scattered and light for most of the coastal regions. However, by the early evening hours, rain showers could intensify across the interior regions of San Luis Obispo and Santa Barbara Counties as a result of thunderstorms. It's possible that some mountains could see 0.25''-0.50'' of rain while the the coastal regions will likely only get about 0.15'' of rain. Cuyama Valley could also receive some light snow as snow levels drop to 2,500 feet.
Looking ahead to the weekend, conditions will dry out and temperatures will start to slowly trend up. By the start of next week, temperatures could reach the low 70s.
