So far this year we had an extremely above normal late winter season in regards to tornados for feb and March. But April has had an extremely below normal so far. That will all likely change over the next two weeks. A very active weather pattern will occur over the Midwest through the south and south east US. Various waves of storms will strike through today and mid week then again fri through Sunday then again early next week. This will likely bring up statistical numbers back to average levels.
Besides the threat for violent tornados to outbreak across a very large area of the country, the other threat will be flooding. Extremely heavy rains will accompany these storm systems, producing a large flood risk across these very same regions possibly multiple times throughout the coming weeks.
This double punch will likely add to the damages, and hinder cleanup and search and rescue missions.
