Scattered showers and storms are moving through overnight across eastern Iowa and could linger into Monday morning, but widespread severe weather is not expected during the overnight hours. The bigger concern comes later Monday, when storms are expected to redevelop between 2 and 4 PM and could turn strong to severe.
Large hail, damaging winds and tornadoes are the main threats early Monday afternoon, with the activity expected to grow into a line as it moves east. Once that happens, the risk shifts more toward straight-line wind damage, though a few spin-up tornadoes remain possible within the line. The storms are expected to leave the area between 7 and 9 PM Monday.
For now, the forecast has the shape of an active start to the work week: a late morning lull after the overnight round, then a recharged atmosphere and a second burst of storms during the afternoon and evening. Temperatures Monday should reach the mid 60s to low 70s, with overnight lows in the mid 40s.
After Monday, the pattern turns quieter. Tuesday through the end of the week is expected to be cooler and drier, with highs in the 60s and lows ranging from the mid 30s to mid 40s. A few scattered showers are possible Thursday afternoon and evening, but those are expected to be on the lighter side.
For anyone watching the tornado Columbia mo forecast, the answer is straightforward: the overnight period should stay below widespread severe levels, but Monday afternoon is the window to watch closely before the threat moves out by evening.
