Weather Underground Forecast for Wednesday, February 06, 2013.

Wet weather conditions will continue across the northeastern quadrant of the nation Wednesday as a low pressure system over the Upper Great Lakes lifts northeastward into southeastern Canada, toward the Canadian Maritimes. Cold temperatures at and below the freezing mark will support snow development across the Lower Great Lakes, eastern Ohio Valley, Central Appalachians, and Northeast, while light rains showers fall along the southern New England coast. Expect generally light snow accumulation with the passing of this system.

To the south, the southern portion of a cold front extending across the Southeast will maintain light to moderate scattered showers and isolated thunderstorms along the central and eastern Gulf Coast. Behind this system, an upper level impulse from northern Mexico will move into the Southern Plains with moisture from the Gulf of Mexico streaming northward ahead of the system. Rain and thunderstorms will organize in eastern Texas and along the Central Gulf Coast as the system moves toward the Southeast.

To the north of this activity, a system from the West will head into the Plains on Wednesday and will meet with increased moisture streaming in from the Gulf of Mexico. Light rain will develop in ahead of an advancing cold front in the Central Plains, while snow showers are anticipated ahead of an associated warm front from the Mid-Mississippi Valley into the Great Lakes

Out West, rain and high elevation snow continues across the Northwest as another cold front advances toward the Pacific Northwest Coast with onshore flow.

Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -18 degrees at Saranac Lake, N.Y. to a high of 90 degrees at Edinburg, Texas
