for a warm-up as temperatures return to near normal values
during the weekend. Probability of Exceedance of reaching 80
degrees shows a steady rise with percentages near 60 percent by
Saturday. During the same time frame, the west side of the San
Joaquin Valley shows a range of 70% to 90% which increases
confidence in that area able to reach the 80 degree mark.

the best timing of fog near sunrise for at least the next two
mornings. Probability of having visibility drop below 3 miles
