Yesterday had a cloudy start at Mazda Raceway, but the clouds quickly disappeared around 10 am. The weather pattern hasn't changed in the past 24 hours, so I expect that today will be very similar to yesterday. As you can see in the satellite image below, there is extensive low cloud cover across the Monterey Peninsula and the Salinas Valley this morning:
The clouds are the yellow areas, and Mazda Raceway is the red dot. These clouds develop overnight due to the northwest wind bringing moisture off the ocean, and cooling with sunset causes the clouds to form. During the day, the clouds dissipate as the surface heats up and the low level moisture becomes mixed with drier air. Like yesterday, clouds should begin to dissipate around 10 am PDT, and once they do, sunny skies will prevail through the day. It will be a little breezy, with northwest winds 10 to 15 mph. Temperatures will be a little cooler than yesterday, with highs in the mid 60s.
