National Weather Service San Francisco Bay Area
830pm PDT Tuesday July 5 2022
A mix of low and mid level clouds continue this afternoon with the potential for drizzle along and near the coast again tomorrow morning. A gradual warming and drying trend begins by midweek, however, below normal temperatures persist today through Friday for the afternoon highs. By Saturday, the region warms back to near to slightly above normal conditions.
As of 08:29pm PDT Tuesday...As the sun sets over the Bay Area and Central Coast and mix of clouds and sun can be seen. Satellite imagery shows strato-cu hugging the coastline and some of the terrain features around the region. A pleasant day weather wise despite seasonably cool temperatures. Temperatures topped out mainly in the 60s and 70s, which is 5-15 degrees below seasonal averages. As noted on the previous felt a tad muggy today due to the higher moisture content in the air. Good news is it is starting to see some drier air working its way in per 00Z OAK sounding. PWAT (Precipitable Water) was 1.03", which is above the 90% moving average, but still lower than the morning sounding.
For tonight - expect some of the strato-cu to fade after sunset, but more widespread coastal stratus is expected to form. Similar to the last few night coastal fog and drizzle will be possible, especially north of the Golden Gate. Current forecast captures the drizzle and clouds so no need for an update.
Wednesday wills start off cool and then warm to a few degrees warmer than Tuesday most areas. Further warming is expected later in the week.
As of 02:07pm PDT Tuesday...Observing widespread areas of stratocumulus clouds via satellite and webcams this afternoon. The low to mid levels of the atmosphere continue to have a higher than usual moisture content thanks to the persistent upper level low spinning off the coast of the Pacific NW. The 12z Oakland sounding indicated that precipitable water (AKA PWAT (Precipitable Water) values, which helps to quantify how much water content is in the air) was 1.25 inches, which is around 200% of normal. At the surface, this has translated to higher than normal dewpoints that range from lower to upper 60s (with temperatures currently in the 70s to low 80s), resulting in the air feeling muggy. Peak "mugginess" will likely be today as a drier airmass moves in tonight/tomorrow and PWAT (Precipitable Water) values are forecast to decrease. Similar to this past morning, coastal areas in the North Bay down to the San Mateo coast could see some light drizzle again in the early morning hours Wednesday. Low clouds and patchy fog also likely again overnight into Wednesday morning. Wednesday during the day will see similar temperatures to today (widespread 70s to low 80s).
By Thursday, this anomalous trough that has been parked over the West Coast will begin to break down as high pressure starts to build in from the desert Southwest. This pattern change will be a more typical summer-like pattern for the region. With this pattern shift, a warming trend will commence and more seasonable temperatures across the CWA are expected (60s to 70s near the coast, 80s in the interior). By the weekend, max temperatures will be toasty again with interior regions reaching the low 90s. Heat Risk remains low through Friday, but come Sunday/Monday interior regions will be at a moderate level for heat risk, meaning sensitive populations should use caution. While this warm up won't result in temperatures in the triple digits inland, the increase in temperatures region-wide still worth emphasizing as temps have been below normal the last few days.
Looking further ahead, deterministic and ensemble long range models are in agreement that this broad region of high pressure will persist over much of the Western CONUS into mid July, so this pattern change is likely here to stay for the foreseeable future.
as of 02:12pm PDT Tuesday...Winds over the waters remain light to breezy and will continue as such through Wednesday morning. Winds will increase along the immediate coastline south of Pigeon Point and down the Big Sur coast Wednesday afternoon which can cause hazardous seas for smaller craft. A 7 to 10 second west swell arrives Tuesday night while a longer period southerly swell prevails through the late week. Winds increase over the weekend for a return to a stronger wind-wave driven sea state.
