Weather Underground Forecast for Thursday, January 26, 2012.
Active weather will spread across much of the East on Thursday as the storm system from eastern Texas lifts northeastward across the Eastern Valleys to the Northern Appalachians. Ample moisture from the Gulf of Mexico will accompany this system and will aid in producing moderate to heavy rainfall and thunderstorms on the northern and eastern edge of this system, from the Central Gulf Coast through the Ohio River Valley and Mid-Atlantic and into the Northeast later in the day. Energy from an associated warm front lifting through the Mid-Atlantic will enhance precipitation in the Ohio and Tennessee Valleys and the Appalachians, while energy from a trailing cold front enhances storms in the Gulf Coast States. There is a slight chance for severe weather development across the central to northeastern Gulf Coast. Damaging wind and isolated tornadoes will be the main concerns with severe storms in these areas. Meanwhile, more light to moderate rain showers and thunderstorms will be possible on the back of this system in eastern Texas.
To the north, a few flurries may be possible in the northern Upper Great Lakes as a low pressure system moves eastward through southern Canada. A cold front associated with this low pressure will extend through the nation¼'s mid-section during the day before dissipating by the evening.
In the West, another wet system will move through the Northwest, bringing rain and high elevation snowfall to areas from the Pacific Northwest and areas of northern California through the Northern Intermountain West and the northern tier of the Central Great Basin. Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -4 degrees at Big Piney, Wyo. to a high of 96 degrees at Bonifay, Fla.
