The Bay Area is bracing itself for another round of chilly weather as frost advisories are set to go into effect again tonight. According to the National Weather Service Bay Area, residents in the southern and interior sections of the Central Coast and Eastern Santa Clara Hills should be ready for frost development through 9 AM PST Monday.

The Area Forecast Discussion by the National Weather Service San Francisco CA detailed, "A Frost Advisory remains in effect until 9 AM PST this morning for interior parts of the Central Coast and Eastern Santa Clara Hills." Today, the forecast promises sunny conditions after any morning fog fades, with highs in the 50s to lower 60s. However, tonight's temperatures will once again plunge into the lower to mid-30s in the frost advisory zones, and elsewhere, the figures will range from the mid/upper 30s to mid-40s.

As for the rest of the week, the region should expect a shift in weather patterns. "Model guidance continues to advertise a very stout 180+kt jet screaming across the Pacific," the National Weather Service San Francisco CA reported. This jet is anticipated to stir up another active weather cycle, potentially reintroducing storms as early as Wednesday and lasting through the following weekend with wind and rain becoming a concern.

Aviation prospects for the region are also in flux with "morning conditions will remain VFR for the Monterey Bay terminals, while a mix of VFR to MVFR conditions prevail around the Bay Area," according to the Area Forecast Discussion. Sub-VFR conditions could return late tonight in the Bay Area, with onshore winds hitting around 10 kt this afternoon. Marine forecasts suggest gentle to moderate northerly breezes today into tonight, a pattern continuing through midweek when shower chances re-emerge towards the end of the week.
