north dakota this afternoon. an associated warm front will move 
north across the lake through today as the low moves northward. 
southeasterly winds will linger through the majority of today,
increasing through this morning. winds become south-southwesterly
tonight, remaining breezy through wednesday. winds become modest

over the cooler waters of the lake. scattered thunderstorms are 
forecast on most days, especially over the north half.
