Sunday saw records break in two places. Concord saw a record high of 81 degrees and Moffett Field saw a record high of 80 degrees.
The record books could be rewritten again Monday in cities like San Francisco. The City was in the 70s in the morning and that puts the record of 80 degrees within sight there. Low to mid 80s are likely in parts of the Bay Area today which Mayeda points out that any time the Bay Area sees highs in the 80s this time of year, records are at risk of being broken.
But the heat wave will be short lived. By Thursday we will be back in the normal range in the mid-60s and by late Friday rain, thunder hail and snow showers are in the forecast.
So break out the sunscreen to start the week, but keep the parkas handy.
