The National Weather Service forecast for the greater San Francisco Bay Area for Sunday calls for cloudy and rainy skies.

Isolated thunderstorms should be expected across Tampa Bay as severe weather moves through the area. Tornado warnings and watches were in effect all throughout Sunday afternoon.

Nicole Carlisle, a meteorologist with the weather service’s Tampa Bay office, said the storms are likely to arrive Sunday evening. The thunderstorms bring the threat of damaging winds and an isolated tornado or two. The weather service expects up to an inch of rain from the storms.

Storms in the Green Bay area are being considered severe, as winds could be as high as 32 miles per hour on Friday, as well as 36 miles per hour Saturday afternoon. Gusts up to 45 mile per hour are possible at times.

A cold front has been moving through the country over the last few days sparking up strong and severe storms. The Storm Prediction Center (SPC) was able to put the caution out for the severe weather outbreak four to six days in advance.
