Weather Underground Forecast for Thursday, January 03, 2013.
Showery weather continues along portions of the Gulf Coast on Thursday as a cold front with waves of low pressure drops southward through the Gulf of Mexico and reaches across the Florida Peninsula. Light to moderate showers along and near the Gulf Coast, from areas of southern Texas through parts of South Carolina, will be scattered and may be accompanied by a few isolated thunderstorms through the afternoon, while heavier rain falls in the central gulf. Behind this disturbance, an upper area of low pressure trekking from northern Baja California inland into northern Mexico will kick up areas of precipitation across southern New Mexico and nearby western Texas. A below normal airmass over the region will support a few inches of snow developments in these areas from the afternoon into Friday.
To the north, snow showers and flurries will continue across the Upper Great Lakes into the Northeast on Thursday as low pressure skirts along the U.S.- Canadian border and associated impulses push across the Great Lakes. While snow accumulations in these areas are expected to be fairly light, snow totals of 2 to 5 inches and isolated higher amounts may become possible downwind of Lake Ontario through early Friday morning.
Elsewhere, high pressure centered over the Rockies and Intermountain West will maintain generally dry weather conditions across much of the West. A weak cold front will approach the the Pacific Northwest and northern California coasts with a few light showers.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -26 degrees at Alamosa, Colo. to a high of 82 degrees at Plant City, Fla.
