Area Forecast Discussion National Weather Service San Francisco CA 224pm PST Sat Jan 25 2025 ...N Marine Synopsis Issued at 138am PST Sat Jan 25 2025 Chilly temperatures begin today and persist into the early part of next week. Light rain showers expected across the Central Coast and gusty offshore winds in the North Bay mountains through the weekend, with the next chance for rain coming towards the latter part of next week. .SHORT TERM... (This evening through Sunday) Issued at 1235pm PST Sat Jan 25 2025 Isolated to scattered rain showers persist across the Central Coast this afternoon as a low pressure system is in place over the San Francisco Bay Area. This is pulling in moisture from the Pacific and there remains a bit of instability aloft that will result in a less than 15% chance of thunderstorms, especially tonight and into Sunday. Forecast rainfall totals have trended downwards, but remain modest with the highest totals reaching 0.33-0.50" in the mountains of southern Monterey and San Benito Counties, and around 0.10-0.33" of rain across the Monterey Bay region and the Salinas Valley. The cold core low will lead to cold temperatures aloft, with snow levels as low as 3,500 feet. As a result, snow will be likely in the higher peaks of the Central Coast with up to around 4" of snowfall. Trace amounts to a few hundredths of an inch can be expected over the North Bay and San Francisco Bay Area . Across the North Bay Interior Mountains, the main forecast issue lies in gusty winds. As such, a Wind Advisory in effect now through 10am Sunday morning. Gusts can reach 50 mph across the ridgelines and highest peaks, resulting in unsecured objects being blown away, difficult driving for high profile vehicles, and possibly a few power outages. Tonight will be another cool night, with Frost Advisories issued for the East Bay Hills/Mountains, interior portions of Monterey and San Benito counties including the southern Salinas Valley from 1am through 9am Sunday. High temperatures tomorrow (similar to today) will be in the low-to-mid 50s in the lower elevations and upper 30s to 40s in the higher elevations. Isolated to scattered rain showers will begin to taper off Sunday night as the low pressure system pushes south of the Central Coast. Long Term (Monday through Friday) Issued at 138am PST Sat Jan 25 2025 Dry weather should return Monday and stick around through at least the mid-week as ridging returns to the region. However, clear skies and light winds in the early part of the week will promote radiational cooling and lead to potential hazardous conditions. Lows in the lower to middle 30s in the inland valleys and the upper 30s into the lower 40s for the coastal regions have resulted in the issuance of a Freeze Watch for the inland Bay Area and all of the Central Coast from Sunday morning to Tuesday morning. Remember the Four P's of Winter Weather: People: Dress in layers and wear a hat that covers the ears. Pay special attention to children and the elderly, who are more vulnerable to the cold. Plants: Bring potted plants indoors and keep outdoor plants and trees protected. Pets: Bring all pets indoors. Pets and other animals that have to be kept outdoors should have an enclosed shelter. Pipes: Make sure all external water pipes are insulated. Keep an interior faucet running at a drip to prevent ice buildup. The NBM continues to show a chance for rain to return towards the latter part of next week, but rainfall amounts and timing depend on the prognosis of an incoming trough and how quickly it erodes the ridging. CPC outlooks show a signal for rainfall totals near or slightly above seasonal averages for the first week of February. Marine (Tonight through next Thursday) Issued at 223pm PST Sat Jan 25 2025 An energetic cold core low pressure system near the north Central Coast will result in gusty northerly winds mainly over the northern coastal waters and unsettled weather through this weekend. Winds will be strongest over the northern outer waters with gale force conditions through this evening. Rough seas continue tonight and Sunday then gradually improve by Monday. The center of the low will reach southern California later Sunday and Monday. Dry weather prevails in our forecast area midweek under a high pressure system. The high then weakens with wet weather returning to the forecast area late in the week. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...Wind Advisory until 10am PST Sunday for CAZ504. Freeze Watch from late Sunday night through Wednesday morning for CAZ504-506-508-510-512>518-528>530. Frost Advisory from 1am to 9am PST Sunday for CAZ514>518.
