A week ago, Tracy was sweltering in 100-plus degree temperatures. Today, unofficial temperatures have the daytime high pegged at about 80.
The reason? You know if you looked toward the Altamont this morning, where fog crept over the hills and wrapped itself partly around the feet of Mount Diablo. The Bay Area's fog is keeping us cool — the the breeze caused by warmer inland temperatures doesn't hurt, either.
The cool but sunny weather is supposed to last as least until Friday. Enjoy it while it lasts.
