No need for a jacket today. Temperatures in the Bay Area should reach the 80s today, with warming trends continuing throughout the week.
In some cities, such as in San Jose and Livermore, early morning temperatures began at 60 degrees on Monday.
High-pressure systems are expected to build with temperatures in the 90s expected Tuesday and Wednesday along with dry, gusty winds, which may warrant some fire weather watches and very early season red-flag warnings for the hills of the north and east bay.
Less wind and more warming for the second half of the week with some inland spots possibly approaching the low to mid 90s. As winds decrease, air quality might be a concern. Ground level ozone levels may climb later in the week, possibly high enough for our first Spare the Air days, something also to watch for toward the end of the week.
