Conditions remain relatively consistent for the rest of the weekend at Sonoma Raceay. Saturday's forecast stays mostly unchanged other than the possibility of some increased cloud cover in the upper levels during the afternoon. For Sunday, recent model runs have been trending warmer with a high temperature near 90°, possibly as a combination of less cloud cover during the morning and northerly surface winds during the day. Previous model runs were indicating winds from the west to southwest, which would have brought air to the region from the Pacific. Winds from the north will move over land, which warms much quicker and to higher temperatures than the water. Dew point temperatures in the mid 40's will likely keep conditions feeling cooler than actual air temperatures.
