Weather Underground Forecast for Tuesday, January 15, 2013.
Active weather will continue in the Southeast, while snow showers move into the Northern Rockies and Northern Plains on Tuesday. A stubborn cold front will remain situated over the Southeast on Tuesday and continue pulling moisture and energy in from the Gulf of Mexico. This will continue triggering moderate to heavy rain showers from the Lower Mississippi River Valley through the Carolinas. Expect rainfall totals to range from 1 to 2 inches in most areas along and ahead of the cold front, while cooler temperatures behind the front will allow for freezing rain and snow showers to persist for the Tennessee Valley. Flood warnings and advisories will remain in effect for the region as the Lower Mississippi River Valley and the Tennessee Vally have seen heavy rain for nearly a week now. Meanwhile, freezing rain warnings will remain in effect for parts of the Tennessee Valley through Tuesday morning. Expect dangerous roads and travel conditions as up to a quarter of an inch ice accumulation is possible.
In the North, a low pressure system drops into the Northern Rockies from western Canada. This will kick up a few snow showers over Montana and Wyoming, moving into the Dakotas late on Tuesday. High wind advisories have been issued for the Northern Rockies as sustained winds from 25 to 40 mph are likely, with gusts up to 70 mph at highest mountain peaks. Snowfall accumulation will range from 2 to 4 inches for these areas on Tuesday.
Temperatures in the Lower 48 states Monday have ranged from a morning low of -36 degrees at Craig, Colo. to a high of 84 degrees at Brunswick, Ga.
