Friday, 23 April
Saturday, April 24 looks like a classic tornado outbreak over the South/Mississippi Valley region (Mississippi, Alabama, Tennessee). In fact, the deep layer shear will be supportive of violent, long track tornadoes.
But there’s more where that came from. We are entering a very active severe weather pattern, which began over the last couple days as shown by the tornadoes occurring over the Plains. By mid and late next week (April 28-3) more tornado setups are expected, and this active severe weather pattern will persist through at least the first week of May. Based on MJO movement and other guidance, I expect this active period of severe weather setups across the Plains to continue through around the second week of May.
