A multi-day severe threat continues today across Iowa and other Western Cornbelt states as a slow moving troughs ejects lows into the Plains. Scattered wind reports were observed yesterday across West Texas. Cities like Sioux Falls and Omaha will spend at least three straight days in severe storm risk areas. A stronger low-ressure system will yield more intense severe weather setups on Sunday & Monday. The long range forecast has considerable uncertainty in late May as some models keep most of the rain across the Southern US whereas few return rains to the High Plains.
