Not much has changed to the ongoing forecast this afternoon. Temperatures today are expected to top out in the upper 50s to lower 60s with mainly clear sky conditions. However, low clouds are forecast to return to coastal areas and into the adjacent valleys overnight. This will help limit overnight cooling, however we have high confidence the interior will remain cold. Thus, a Freeze Warning has been posted from 1am to 9am Wednesday for interior Central Coast (including the southern Salinas Valley) and southern East Bay hills/mountains. A Frost Advisory is in place for the same time as the Freeze Warning for interior North Bay, northern Salinas Valley, and Santa Clara Valley (excluding the city of San Jose). ∨

Wednesday will be a bit tricky with respect to forecast maximum temperatures as areas that do have low clouds develop will be slower to warm. That said, the current forecast has high temperatures in the low-to-mid 50s in coastal areas and upper 50s to near 60° across the interior. ∨

An Omega [term used to describe vertical motion in the atmosphere] blocking pattern should persist through at least Thursday with a trough developing over the Pacific Northwest beginning to flatten the ridge by Friday. This is when the pattern shift will begin to bring rain chances to the region. However, the latest forecast (similar to previous runs) is putting the main focus over the North Bay with respect to rainfall from Friday through the weekend. The latest ensemble guidance has more zonal flow [Large-scale atmospheric flow in which the east-west component is dominant] over the Bay Area and Central Coast, while upper level troughing is observed over the Pacific Northwest. Thus, the deeper moisture tap will be across the North Bay and points northward. ∨

The zonal flow [Large-scale atmospheric flow in which the east-west component is dominant] will be kicked southward as a mid/upper level low drops southward just off of the Pacific Northwest coast by Monday and Tuesday, this will bright more widespread rain the areas south of the Golden Gate and across the Central Coast. There remains a great deal of uncertainty beyond Monday, so expect the forecast to change in the coming days and as we get closer to the weekend. ∨
