Weather Underground Forecast for Thursday, March 31, 2016
A low pressure system will bring impacts to the central and eastern thirds of the country on Thursday, while high pressure rebuilds over the West Coast.
An area of low pressure will trek northeastward from the upper Mississippi Valley to southeast Canada. This system will usher moderate to heavy snow across the upper Midwest, while light to moderate snow will trail this system over the northern Plains and the Intermountain West. A cold frontal boundary associated with this system will stretch south southwestward from the western Great Lakes to the southern Plains. As this frontal system transitions east northeastward, it will collide with warm and humid air from the Gulf of Mexico. The result will be widespread rain and thunderstorms from the Mississippi Valley to the Eastern Seaboard. Severe thunderstorms will be possible in Louisiana, eastern Arkansas, southeast Missouri, southeast Illinois, Indiana, western Kentucky, western Tennessee, Mississippi, Alabama and the western tier of the Florida Panhandle. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain will also bring threats of flash flooding to a large span of the Deep South.
States located west of the Continental Divide will stay clear of wet weather due to a ridge of high pressure over the West Coast.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 6 degrees at Wolf Creek Pass, Colo. to a high of 90 degrees at Dryden, Texas
