On the heels of the last storm of the winter, which wetted Bay Area roads and coated Sierra Nevada ski slopes with snow over the weekend, a heat wave is expected to grip the region this week and flirt with breaking a few temperature records.

A large ridge of high pressure building off the coast is expected to move inland and usher in warmer conditions into the 70s and 80s for Tuesday and Wednesday, according to the National Weather Service. The heat wave, bolstered with offshore flow, could break some record temperatures Tuesday in the North Bay and on the Peninsula. High marks of 84 degrees set in Santa Rosa in 1926 and 75 degrees in San Francisco, passing the 1970 record of 73 degrees, are possible.
