A warming trend will continue across the Bay area as high pressure shifts east across the Atlantic on Tuesday, giving us a southeast wind flow. Temperatures will run a few degrees above average with daytime highs in the upper 70's on Tuesday and lows in the upper 50's.
Overnight we will see areas of patchy fog after 1 am. Low level moisture, mostly clear skies and light winds will combine to set the stage for fog development. If you have to be on the roadways overnight and encounter fog, make sure to use your low beam headlights and drive with caution leaving extra space between you and the vehicle ahead.
A weak cold front will move the region late Tuesday into Wednesday morning. We will stay dry as only limited moisture is associated with the front. Other than a brief drop in humidity along with the front, temperatures will stay very mild through the end of the workweek.
