Weather Underground midday recap for Sunday, January 20, 2013.

Much of the Midwest experienced colder temperatures on Sunday as a cold, arctic airmass from the north surged into the northern tier of the nation behind a strong cold front from Canada. After a brief period of above normal daytime highs on Saturday, many areas from the Northern Plains through the Great Lakes began to see a significant temperature drop by up to 30 degrees due to this cold snap. High temperatures in the single digits to lower and mid-teens became fairly widespread across the Dakotas and the Upper Midwest by the afternoon. Wind chill advisories were issued for the Upper Midwest as strong winds gusting to 40 mph were expected to create dangerously cold conditions Sunday night into Monday. Meanwhile, in addition to cold temperatures, this small yet potent disturbance triggered a lake effect snow event downwind of the Great Lakes and across the interior Northeast. Snow accumulations of 5 to 8 inches were anticipated along the downwind shores of the Great Lakes, while most areas experienced 1 to 2 inches of new snow.

Elsewhere, outside of a few light showers in the Florida Peninsula, a quiet weather day developed across the rest of the nation. High pressure in the West, led to air stagnation issues with reduced air quality and lowered visibilities in the Pacific Northwest.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of -22 degrees at Kremmling, Colo. to a midday high of 82 degrees at Opa Locka, Fla.
