Severe storms, flooding, and a cold air plunge on tap starting Tuesday
It may still be January but severe weather is on tap for the South, lower Midwest, and eventually the mid-Atlantic U.S. from late Monday night through Tuesday and Wednesday. While there is a risk of tornadoes in this storm system, the largest and most widespread threat will be from straight-line wind damage. Given the speed of the jet stream, which will be whipping far above the Earth at around 150 mph, the storms are going to be moving QUICK—some as fast as 70mph.
The Storm Prediction Center has issued a moderate risk of severe weather, meaning there will be substantial area of severe storms, or an enhanced chance for a significant severe storm outbreak. In this particular case, it also means we're expecting intense lines of thunderstorms with widespread damaging winds.

Flood Threat
Strong, southerly winds ahead of the cold front will also bring unusually moist air well north of the Ohio River. For some areas it will be among the most humid January air masses in recent history, and the resulting heavy rainfall threat over frozen ground has prompted the National Weather Service to issue flood watches for Indiana and parts of nearby states.
3-day precipitation forecast ending Thursday evening from the HPC.
Cold Air Surge
This storm's cold front will also bring with it some chilly air. Many locations will see 25-30 degree temperature swings. Highs on Wednesday won't get above 0°F in Montana and North dakota. Sub-freezing air will dip as far south as Missouri. On Thursday the cold air pushes east with highs only reaching the 'teens and twenties in the Great Lakes states. On Friday the Northeast will see highs in the mid-thirties.
