Similar pattern for stratus return expected this evening. Clearing to VFR expected by about the 17-18Z hour for most terminals. Marine layer remains relatively compressed below 1000 feet, likely not enough to see widespread dense FG, but fully expect some patchy FG through sunrise this morning. Stratus slower to fill in this morning compared to yesterday morning, though is expected to impact most terminals with the exception of KLVK. (12Z TAFS) Issued at 345 AM PDT Wed May 17 2023 Overall temps inland will oscillate in the 70s and 80s with upper 50s to low 70s along the coast.ĪVIATION.

Still no solid chances of any precipitation in the extended forecast as dry weather conditions persist. That will allow for a bit of warming early next week for the interior. Over the weekend, the large low pressure system that was centered west of the CA/OR border will gradually lift northward and allow ridging over CA to slightly strengthen. The ridging over our CWA will gradually weaken which will allow for a subtle cooling trend across the interior into the weekend, but we are not expecting any notable temperature swings. The synoptic pattern described in the short term won't change much through the rest of the work week. (Thursday through Tuesday) Issued at 351 AM PDT Wed May 17 2023 A return of stratus tonight is likely given the persistent pattern. Areas closer to the coast and around bay shorelines will be in the upper 50s to low 70s. Expect highs across the interior to range from the 70s and 80s with a few spots reaching the low 90s. The synoptic pattern overhead hasn't changed much: ridging over CA extending northward into the west coast of Canada as a large upper low spins over the Eastern Pacific centered about 980 miles west of the OR/CA border while a weak low is centered just off the coast of Baja California to our south. The Fort Ord Profiler indicates that the marine layer has leveled off to around 1000 to 1200 ft deep. The main difference tonight is that there's not as far of an inland push into the East Bay. all around the Monterey Bay shoreline and filling the Salinas Valley. typical East Bay areas (Richmond, Berkeley, Oakland, Castro Valley, Hayward).

A solid inland push of low coastal clouds into Sonoma & Marin counties including southern Napa county. Nighttime satellite imagery shows a somewhat similar image to what we saw last night. (Today and tonight) Issued at 351 AM PDT Wed May 17 2023 Otherwise, dry weather conditions will prevail through the forecast period with slight cooling late week and into the upcoming weekend. Issued at 351 AM PDT Wed May 17 2023ĭaytime highs remain warmer across the interior while coastal areas will hold near to slightly below normal highs due to the cooling influence of coastal stratus.
