DES MOINES, Iowa (AP) — Most legislative action is being cancelled Thursday at the Iowa Capitol because of a snowstorm expected to sweep through the state. The National Weather Service predicts up to 10 inches of snow could pile by Thursday night in Des Moines, and heavy snow is forecast for much of the state. Gusty winds also are expected. The House and Senate will convene Thursday, but no floor action is scheduled and most committee hearings have been cancelled.
