Area Forecast Discussion National Weather Service San Francisco Bay Area 148 PM PST Fri Jan 28 2022

SYNOPSIS. Mild days and cool nights will prevail over the region into next week along with dry weather conditions.

DISCUSSION. as of 01:47 PM PST Friday . High pressure over the West continues to support dry weather conditions and mild temperatures over the Bay Area and Central Coast. Light offshore winds are helping to aid in the warm, dry air mass aloft resulting in afternoon temperatures reaching into the 60s to lower 70s. An increase in high cloud cover overnight may limit how much temperatures can cool, yet still expecting 30s in the colder interior valleys with widespread 40s elsewhere.

No significant changes in the overall weather pattern expected through the upcoming weekend. Thus, temperatures during the day will run 5 to 10 deg F above seasonal averages with cool nights/mornings. High pressure will dominate the eastern Pacific next week as a mid/upper level trough drops into the Pacific Northwest and then the Great Basin around midweek. This will help to cool temperatures slightly and also produce another round of offshore flow Tuesday into Wednesday.

Forecast ensembles heavily favor dry weather conditions to persist heading into the first week of February as well. Thus, the short- term through the 8-14 Day Outlook from the Climate Prediction Center indicates continued dry weather conditions and above normal temperatures.

AVIATION. as of 10:00 AM PST Friday . For the 18z TAFs. VFR across TAF sites. Satellite imagery shows high clouds rotating around a low pressure system several hundred miles off the SoCal coast. This will bring periodic mid/high clouds over the area through much of the TAF period. Drying offshore winds will keep low clouds limited through the period with VFR conditions prevailing. Winds remain light and variable with locally breezy conditions. Vicinity of KSFO . VFR expected through the period. Light and variable winds through the afternoon, turning light onshore towards early evening. SCT/BKN between 15000-20000 ft this morning with some clearing this afternoon.

KSFO Bridge Approach . Similar to KSFO.

Monterey Bay . VFR through the TAF period. Breezy SE winds (up to 15kt) in the Salinas Valley through the early afternoon, then becoming lighter and onshore. SCT/BKN high clouds 15000-20000 ft through much of the period.

MARINE. as of 08:41 AM PST Friday . Some breezy easterly winds along the coastline this morning. Strongest winds will be through the Northern San Francisco Bay and coastal gaps which may be hazardous for smaller vessels. Winds are forecast to return to light and variable by this afternoon. A pair of light, moderate period, west northwest swells will move through the waters over the next few days. Northwest winds expected to increase early next week and are capable of building wind waves that may exceed 10 to 15 feet as the next northwest swell arrives.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. None.
