Weather Underground midday recap for Thursday, January 17, 2013.
Active weather continued for the Southeast, cold air continued to spread across the East, and the West remained sunny and chilly on Thursday. A frontal boundary over the Southeast continued pulling moisture onshore from the Gulf of Mexico and allowed for heavy rain showers to spread from the Tennessee Valley through the Mid-Atlantic states. Rainfall totals varied around 1 inch from Georgia through Maryland. This allowed for flooding to remain of concern across the Tennessee Valley and the Lower Mississippi River Valley. At the same time, cooler temperatures along the back side of this system allowed for freezing rain and snow showers to develop over Arkansas, Mississippi, and Tennessee. Snow accumulation remained less than 1 inch in these areas. Heavier snowfall developed at higher elevations of the Central and Southern Appalachians with mid-day snowfall totals from 1 to 3 inches.
Meanwhile, in the North, a cold front continued moving through the Great Lakes and Northeast and produced a few more scattered snow showers across the region. Downwind shores of the Great Lakes saw over 5 inches of new snow on Thursday.
Out West, high pressure maintained chilly conditions for the West Coast. The Western states saw the beginning of a warming trend, but overnight and early morning low temperatures dropped below freezing again. Thus, frost and freeze advisories remained in effect for the interior valleys.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of -20 degrees at Kremmling, Colo. to a midday high of 82 degrees at Cocoa Beach, Fla.
