GREEN BAY, WI (WTAQ) - Northeast Wisconsin drivers are in that $4 dollar a gallon neighborhood when filling their tanks. 

The AAA's Nancy Cain says it's too tough to predict how high prices will rise.

Wisconsin's all-time high gas price is $4.12 set last May 5th. 

Cain says factors like refineries switching over to their summer blends and getting close to the summer driving season won't help bring prices back down. 

Prices are at the $4 dollar a gallon mark in places like Crivitz, Sister Bay and Sturgeon Bay.
