Frost advisory issued for Wednesday night

Frost advisory issued for Wednesday night

The cold air from Tuesday's Pacific storm settled to the ground across much of San Diego County overnight after the winds died out, widely dropping temperatures into the 20s and 30s for the first time this fall. San Diego didn't get quite that cold -- but the mercury fell to 41 in Balboa Park. The cold came as a surprise to many; the National Weather Service did not forecast such low temperatures across such a wide area. Even the beaches were cold. The big change also was caused by the quick dispersion of the clouds. There was nothing to hold warmer air near the surface.
Today's highs will reach the 60s at the coast and 50s inland. But the National Weather Service already has issued a frost advisory for Wednesday night, saying that this evening could turn out to be even colder.
Forecasters say skies will be mostly clear today, and clear again tomorrow, when San Diego State and Brigham Young square-off in the Poinsettia Bowl at Qualcomm Stadium. Kick-off: 5 p.m. Temps will be in the upper 50s.
Winter officially begins on Friday.
