Area Forecast Discussion National Weather Service San Francisco CA 458am PDT Thu July 17 2025 .SHORT TERM... Issued at 240am PDT Thu July 17 2025 (Today and tonight) We're more than halfway through the month and "No Sky July" remains locked in. Current overnight satellite fog product shows another robust marine layer blanketing the coastal waters and inland valleys. Fort Ord profiler indicates the depth of the marine layer actually increasing a little since Wednesday. The slight deepening is likely due to a weak/subtle upper level shortwave trough over NorCal coast. The deeper marine layer was just enough to hamper another "drizzle-fest" along the coast. We've had one gage tip since midnight, which is less than 24 hours ago. That being said, will still carry some patchy drizzle in the forecast for the coast Thursday morning. Morning clouds will give way to inland sunshine. Despite some inland sunshine temperatures will still be seasonably cool for July with highs reaching the upper 50s to near 70 for the coast and 60s to lower 90s inland -- or about 5 to 10 degrees below normal for July. Speaking of below normal - July 1 through July 16 has shown high temperatures on average are 1 to 3 degrees below normal. Who remembers July of 2024? If you do, it was so much warmer than 2025. Temperatures on average for the whole month of July were 2 to 4 degrees warmer than average with inland areas 6 to 8 degrees warmer. Expect similar conditions again Thursday night into Friday - solid marine layer with some patchy coastal drizzle. Previous discussion highlighted fire weather concerns above the marine layer and those concerns remain early Thursday morning. Dry and mild conditions remain at 2000 feet and above with temperatures in the 60s to lower 70s with poor humidity less than 30%. Long Term Issued at 328am PDT Thu July 17 2025 (Friday through Wednesday) While we're talking about seasonably cool July so far we will see some warming in the long term. Interesting longwave pattern over CA Friday and into the weekend. Two upper lows continue to spin with one retrograding off the NorCal coast and the other is move through N Baja/SoCal. In between is a squeezed upper level ridge. This ridge will result in higher 500mb heights, warmer 850mb temps, and a slightly more compressed marine layer. As such, a slight uptick in temperatures can be expected Friday and over the weekend. Temperatures through this period will warm 3 to 5 degrees each day with far inland areas reaching the mid to upper 90s. Daytime temperatures will warm, but overnight will see some relief limiting HeatRisk impacts for the region. The warm up comes to an end early next week as another upper level trough/low takes aim at NorCal. Expect the marine layer to deepen once again. One other fall out from the trough will be increasing northerly winds. Cool and winder conditions will linger through at least Wednesday. Marine (Today through Tuesday) Issued at 458am PDT Thu July 17 2025 Expect light to moderate winds across the majority of the coastal waters through this weekend. Gusty winds, potentially hazardous to small craft, develop each afternoon and evening through the Golden Gate and into the Delta as well as the favored coastal jets along Pigeon Point and Big Sur. Moderate seas also continue through the remainder of the work week, rebuilding to become rough in the outer waters by Saturday.
