Weather Underground Forecast for Wednesday, January 02, 2013.
Active weather continues across the southeastern corner of the nation on Wednesday as a frontal system extending from the western Gulf of Mexico through the Carolinas slides southeastward. Ahead of this storm, moisture streaming out of the Gulf of Mexico will dwindle down and limit showers and thunderstorms across the region, allowing this activity to become more scattered as the day progresses. The heaviest rainfall totals from this disturbance are expected across the Carolinas as a wave of low pressure along the boundary impacts the region.
To the north, cold temperatures will support snow shower development from the Northern Plains through the northern Upper Great Lakes and into parts of the Northeast as a frontal system from Canada drops southward into the northern tier of the nation. While energy associated with this system will kick up light to moderate snow showers in these areas-especially downwind of the Great Lakes, snow totals from this disturbance will be fairly light.
Elsewhere, high pressure centered over the Rockies and Intermountain West will provide generally calm and dry weather conditions across the West.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -22 degrees at Pinedale, Wyo. to a high of 80 degrees at Punta Gorda, Fla.
