THROUGH THE CENTRAL AND SOUTHERN GREAT PLAINS, WITH A SURFACE
CIRCULATION ORGANIZING ACROSS THE MID-SOUTH AND LOWER OHIO
VALLEY. THIS DISTURBANCE WILL SPREAD LIGHT TO MODERATE RAIN
THROUGH THE REGION, BUT THE HEAVIEST TOTALS WILL BE ALONG THE

EASTERN CONUS. WHILE TEMPERATURES ON THURSDAY WILL BE NEAR
NORMAL VALUES FOR MID-DECEMBER. AS 850 MB TEMPERATURES DIP TO
