In the West, showers are returning to the Pacific Coast, although inland accumulations of rain and snow are expected to be light. Snow is diminishing throughout the Intermountain West.
On the Plains, cloudy albeit cold weather dominates. Overnight lows fell below 0°F on the northern High Plains, where snow cover remains patchy and light in some spots. Daytime highs are forecast to stay below freezing as far south as northern Texas.
In the Corn Belt, snow showers linger this morning in the northern Mississippi Valley, with local accumulations of several inches possible. Meanwhile, moisture from an intensifying southern storm system is reaching the Ohio Valley, and snow will develop across the region throughout the day.
In the South, rain is moving eastward from the western Gulf Coast States and is expected to reach northern Florida overnight. A light freeze was recorded this morning in southeastern Georgia and northern Florida, but temperatures stayed above freezing in the primary citrus areas.
Outlook: Throughout the day, showers and thunderstorms will gradually overspread the Southeast as the winter storm currently positioned over the western Gulf Region intensifies and moves eastward. Snow is expected to develop by this evening over the Ohio Valley and mid-Atlantic Region before reaching New England by Saturday evening. Meanwhile, cold, mostly dry weather will continue on the Great Plains, but bitter cold (temperatures at or below 0°F) is expected to shift away from the High Plains wheat areas toward the upper Mississippi Valley. Precipitation is forecast along the Pacific Coast through the weekend, although inland snow accumulations are expected to remain relatively light. The NWS 6- to 10-day outlook for January 2-6, 2013, calls for the continuation of wet conditions from Texas to the southern Atlantic Coast and in the Great Lakes Region. Drier weather is expected from the Southwest to the upper Mississippi Valley, including much of California, the Rockies, and northern Plains, as well as New England. Below-normal temperatures are forecast along the Atlantic Coast and in the Southwest from California to West Texas. In contrast, warmer-than-normal weather is expected on the northern Plains and in the upper Midwest.
