Weather Underground Forecast for Thursday, Jan. 9, 2014
A cold front is forecast to extend from the central Mississippi Valley to the Mid-Atlantic coast on Thursday, while a separate frontal boundary will extend across the Intermountain West and over the southern Plains.
An area of precipitation associated with a cold front will push across the eastern third of the country on Thursday. A swath of snow showers is expected to impact the Ohio Valley and parts of the Northeast, while the central Mississippi Valley and Tennessee Valley will have a chance for freezing rain and sleet. Rainy conditions will push across the southeast on Thursday. States that can expect wet weather include Tennessee, the Carolinas and Georgia. An onshore flow from the Atlantic will also aid in providing showers and thunderstorms to southern Florida.
The northern Plains and upper Midwest will continue to experience cold, blustery conditions as an arctic air mass sweeps across the northern tier of the country. Just to the west, a pocket of energy will trigger heavy snow across the central and northern Rockies. An onshore flow will also fuel rainy weather across the Pacific Northwest, which will initiate snow showers across the Cascades. Rain will be possible from the coast of Washington to the northwestern tip of California.
The Southwest will continue to stay clear of wet weather due to a high pressure system over the eastern Pacific.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -34 degrees at Crane Lake, Minn. to a high of 69 degrees at Miami, Fla.
