More big changes in the weather are coming. After an ice storm Sunday and an about-face with highs yesterday in the 50s and 60s, thunderstorms rolled over Iowa last night.

Forecasters say temperatures will drop today and a Winter Storm Watch is now posted for counties from southwest to central to northeast Iowa. Meteorologist Aubrey Wilkins, at the National Weather Service, says make sure your snowblower is full of gas.

There’s the chance of heavy snow, with four to six inches possible across parts of central Iowa. Wilkins says the topsy-turvy weather will continue tomorrow as an arctic blast will make its way toward Iowa.

Wilkins says lows by tomorrow night will be in the single digits or below zero, a turnaround in two days of 60 degrees. High temperatures by the weekend will likely be back in the 20s and 30s, more the norm for the season.
