...Heavy snow is possible in higher elevations of the Rockies, while a few inches of snow is possible near Lake Superior...

A potent front that has been lingering in the Central Plains and Middle Mississippi Valley over the past couple of days will begin to move today as a low tracks northeast--a warm front will lift northward east of the low, while a cold front moves through the Central/Southern Plains and Rockies over the next couple of days. A significant moisture plume from the Gulf of Mexico will flow into the frontal system, causing widespread heavy rain and potentially severe thunderstorms. Today, there is a Moderate Risk of excessive rainfall and an Enhanced Risk of severe weather for the ArkLaTex region. Tornadoes, wind, hail, and flash flooding are all possible there. Slight Risks of severe weather and flash flooding both extend into the Central Plains and parts of the Middle Mississippi Valley today as well. On Thursday, the Moderate Risk of flash flooding will be located along the Western Gulf Coast as the cold front shifts southeast, and a Slight Risk of severe thunderstorms is in place for the Lower Mississippi Valley. Showers and thunderstorms will extend into the Tennessee and Ohio Valleys and the Southeast on Thursday ahead of the
front, reaching the Eastern Seaboard on Friday.
