SOME LIGHT SNOW ACCUMULATIONS POSSIBLE OVERNIGHT THOUGH AS SURFACE TEMPERATURES DROP TO FREEZING AND BELOW. SYSTEM HOWEVER IS EXPECTED TO WEAKEN DURING THIS TIME AS IT GETS ABSORBED INTO BROAD TROUGH OVER THE EASTERN CONUS BY THURSDAY MORNING.
541 AM CST WED FEB 24 2016 CURRENT SURFACE ANALYSIS SHOWS RIDGE AXIS POSITIONED IN NW MINNESOTA. THE WAVE THEN ELONGATES AS IT ROUNDS THE BASE OF THE LONG WAVE TROUGH. AND PHASES WITH THE UPPER LEVEL FLOW FROM THE CLOSED LOW OVER THE CENTRAL GREAT LAKES THROUGH THE NIGHT.
