937pm PDT Tuesday July 27 2021
Light showers have pushed northward out of our forecast area this afternoon. Long range forecast is seasonably warm and dry through the rest of the work week. Slight cooling starts by Saturday as marine air pushes farther inland over the weekend.
as of 09:10pm PDT Tuesday...Currently, stratus is making its way back inland near the usual spots, including Monterey Bay and through the Golden Gate gap into the East Bay hills. Temperatures this evening were warmer in some areas that saw more sunshine today, including KMRY which hit a daily record high at 80 degrees around 2:40 PM. Some East Bay locations, including Concord and Livermore, were a few degrees warmer than the forecast. A slight warming trend is still forecasted for tomorrow, with the warmest spots being inland areas which are away from the marine layers influence. The forecast still looks on track. With the warmer temperatures in the East Bay today, those maximum temperatures could be raised by one or two degrees for tomorrow making for a warm summer day.
With this said, all of our guidance keeps temperatures below any critical thresholds for dangerous heat. HeatRisk stays in the low to moderate risk through Friday for most of the area. Cooler air moving in this weekend should knock the central CA coast and Bay Area back down to seasonal.
that the last of the light showers has now pushed north of Sonoma and Napa counties meaning that "Sprinkle Watch" is over for our CWA. We had several reports on social media of folks seeing rain drops in their neighborhoods across the Bay Area this morning into afternoon. Much of the precipitation was just trace amounts, but there were a few isolated spots that measured around 0.01-0.03".
The rest of this week puts us in a fairly stagnant synoptic pattern as a broad and large high pressure cell dominates much of the CONUS through Friday. With that high pressure stretching into the west coast, we'll see warm and dry weather in our region, particularly for our interior locations. Meanwhile, coastal locations will have more mild temperatures, but could still be a bit warmer than normal. The temperature range for coastal areas will be in the 60s and 70s this week while inland spots range in the 80s and 90s...could see a few triple digit marks this week in the hotter areas of our CWA, but nothing widespread. As stated in prior discussions, the inland spots will generally range about 5-10 degrees above normal. However, at this time, we are not at risk for this turning into a significant heat event. Folks in those 90-100 degree locations will still want to make sure they stay hydrated and avoid strenuous work during the heat of the day, though.
As we approach the weekend, an upper level low off the coast of Canada will have a trough extending southward off the CA coastline. On Saturday and Sunday, that low will nudge inland and weaken the large CONUS high. As this occurs, we'll start to cool into a more seasonable range as the marine layer will build back and usher in the cooler, moist marine air.
Have taken a look at long range models and there seems to be a hint of another round of monsoon moisture making it's way into CA again. The main difference is that the moisture will likely stay east of our forecast area and be more of an impact for the Sierra.
