Clear conditions with warm temperatures continue to dominate the forecast for the Indycar Grand Prix of Sonoma at Sonoma Raceway. High temperatures for the weekend are expected to stabilize around the mid-to-upper 70's and with dew point temperatures in the upper 40's to low 50's, heat index values should remain close to the actual temperature. Some moisture in the upper levels could bring some light cloud cover to the region in the late afternoon to evening on Friday, but otherwise conditions will remain clear. Expect maximum wind speed of 5-10mph from the west to southwest each day.
