A highly impactful, major Spring storm will produce numerous hazards over the next few days as it strengthens over the Southern Plains Monday night and pushes northeastward Tuesday across the Mid Mississippi Valley, Ohio Valley and into the Lower Lakes, becoming nearly stationary over the Lower Lakes on Wednesday. Severe weather likely to develop across portions of the Southern to Central Plains late Monday afternoon/evening and spread northeastward quickly across the Lower Missouri Valley, Mid Mississippi Valley Monday night into early Tuesday. This severe weather threat will then spread into portions of the Ohio Valley, Tennessee Valley and Southeast on Tuesday. Large hail, high winds and tornadoes are all possible with this severe weather over the next two days. In addition to the severe weather threat, heavy rains and flash flooding will also be possible late Monday into Tuesday from the Lower Missouri Valley, across the Mid Mississippi Valley, Ohio Valley and into the Central Appalachians. Flood watches currently stretch from central Illinois, across large portions of Indiana, Ohio, northeast Kentucky, much of West Virginia, far southwest Pennsylvania and far western Maryland. As this storm deepens on Tuesday across the Mid Mississippi Valley/Lower Lakes region, precipitation will change to snow on the northwest side of the system from northern Illinois, across much of Wisconsin, the U.P. of Michigan and the northern L.P. of Michigan. Early Spring heavy snowfall totals of 4-8"+ possible across these areas, with regions from eastern Wisconsin into the Upper Peninsula of Michigan having the greatest chances of heavy snowfall. By late Wednesday afternoon another area of low pressure is forecast to begin to deepen along the Mid-Atlantic coast. Heavy snows are forecast to begin to develop late late Wednesday afternoon and continue into Thursday to the north of this low across portions of Upstate and Northern New York into much of central to northern New England. Much above average temperatures will continue across the South on Tuesday ahead of a strong cold front forecast to be pushing eastward from the Southern Plains Tuesday and into the Southeast by Wednesday. Record high overnight low temperatures are possible ahead of this strong front Tuesday morning from the Lower Mississippi Valley, Tennessee Valley, Southern Appalachians and Southeast and again Wednesday morning across the Southeast and most of Florida. In the wake of this front pushing eastward across the South, much cooler temperatures are forecast across the South on Wednesday and the Southeast by Thursday. In the wake of the strong cold front moving eastward late Monday into Monday night across the Southern Plains, windy conditions combined with low relative humidities will support an enhanced to critical fire weather threat. Red Flag warnings for these fire weather conditions are currently in effect across portions of West and Southwest Texas for late this afternoon into this evening.
