Weather Underground midday recap for Thursday, November 22, 2012.
Rain and snow showers developed across the Northern Plains on Thanksgiving, while the Western states saw a break in wet weather and the Eastern states remained dry. A low pressure system moved off the Northern Rockies and eastward across the Northern Plains. Counter clockwise flow around the system created a cold front that stretched southward across the Dakotas, which moved eastward into Minnesota throughout the day. Warmer temperatures ahead of the front produced scattered rain showers, while colder temperatures behind the front allowed for rain showers to turn to freezing rain and snow showers. Winter weather advisories were issued across eastern North Dakota and most of northern Minnesota as 1 to 4 inches of snow were expected on Thursday. Strong winds also accompanied this system with gusts from 30 to 40 mph. Strongest wind gusts were reported up to 46 mph at Rapid City, South Dakota. The southern side of this cold front stretched over the Mid-Mississippi River Valley and into the Southern Plains. As this front moved eastward, it produced a few scattered showers and thunderstorms, but significant rainfall and strong thunderstorms were not reported.
Elsewhere, a ridge of high pressure remained the dominant weather feature for the East Coast and Eastern Valleys. This maintained dry and sunny conditions with highs ranging in the 70s in the Southeast, to the 50s in the Northeast. High pressure also built over the West Coast, which created and calm and pleasant day.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 5 degrees at Alamosa, Colo. to a midday high of 84 degrees at Alice, Texas
