Weather Underground midday recap for Sunday, February 03, 2013.
Cold weather continued from the Northern Plains and Upper Midwest through the Northeast and into the Mid-Atlantic this Super Bowl Sunday as an upper trough of low pressure remained dominant in the eastern third of the nation. The system maintained a cold northwesterly flow across the region, causing daytime highs to reach well below average values. As cold air poured in from the north, the system also directed a series of disturbances through the region with generally light, scattered snow showers. Areas immediately downwind of the Great Lakes experienced heavier lake effect snow showers through the afternoon with periods of blowing and drifting snow as well as lowered visibilities.
Meanwhile, in the South, high pressure prevailed across the Deep South Sunday afternoon with dry conditions and mild temperatures. A more active weather pattern developed across the Southwest and Southern Rockies as weak waves of energy pushed across the region with scattered rain and high elevation snow.
Elsewhere, outside of a few light showers in the Pacific Northwest due to an advancing cold front, generally dry and calm conditions developed across the rest of the West.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of -15 degrees at Clayton Lake, Maine to a midday high of 80 degrees at Edinburg, Texas
