What an amazing March it’s been with 2 notable wind, wave and coastal flood makers and the last 2 major snow makers. This will be the 4th Nor’Easter in 3 weeks and 5th in 5 weeks. The next arrives tomorrow into Wednesday but this time it’s not just snow but severe weather with is now underway in the Deep South.

As the system crossed the Plains today, it’s drawn up warm, moist Gulf air which of course begins to build at this time of year but while remaining very cold over Canada. This system will have a distinct spring side on it’s southern flank where the interior Southeast is under a threat for significant severe weather and flash flooding while the Mid-Atlantic and Northeast could see a major late March snowstorm.

A dangerous night is ahead with several tornadoes expected across the Southeast, some of which could be strong tornadoes. Track the #severe storms and get your latest forecast here: https://t.co/RqMEhzNaZB pic.twitter.com/8PILbjBpRH
