LOW PRESSURE AROUND 29.4 INCHES OVER THE CENTRAL GREAT PLAINS

AS IT CROSSES LAKE MICHIGAN BY LATE TONIGHT. GUSTY SOUTH TO
SOUTHEASTERLY WINDS WILL OCCUR OVER THE SOUTHERN HALF OF LAKE
MICHIGAN THIS EVENING AS THE LOW APPROACHES, VEERING SOUTHWEST
LATE. LIGHTER EAST WINDS ARE EXPECTED FOR THE NORTH HALF OF THE

AS THE LOW DEPARTS TO THE NORTHEAST EARLY FRIDAY MORNING, IT
SWINGS A COLD FRONT SOUTHWARD ACROSS THE LAKE. GUSTY NORTH TO
