Weather Underground midday recap for Sunday, December 16, 2012.

A strong and complex storm system moved through the Great Lakes and headed toward the East on Sunday. As the system trekked eastward, scattered rain and snow showers developed across the Great Lakes and advanced into the Northeast during the afternoon hours. Meanwhile, a strong and energetic cold front associated with this system became quasi-stationary this afternoon as it reached across the Eastern Valleys and into eastern Texas. Scattered showers, with periods and areas of heavy rains, and strong thunderstorms developed along and ahead of this cold front as it pulled ample moisture in from the Gulf of Mexico. Areas from southeastern Texas through central Alabama were at slight risk of severe thunderstorm development through the evening and possibly overnight hours. While heavy downpours, damaging winds and large isolated hail were the main concerns with severe thunderstorms in these areas, conditions were also marginally conducive for a few tornadoes.

Out West, wet weather activity continued across the West as another Pacific Storm moved inland with a moisture tap from the Pacific Ocean. This allowed for rain showers to persist for the Pacific Northwest and California coasts, with more snow showers in the mountains. The system that brought heavy precipitation to the Desert Southwest became absorbed in this system, producing more snow showers over the Great Basin as well as the Central and Southern Rockies.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of -17 degrees at Clayton Lake, Maine to a midday high of 84 degrees at Weslaco, Texas
