Thunderstorms for the Mid Mississippi Valley on Tuesday
A cold front is forecast to track to the east throughout the afternoon and evening over the region. With warming temperatures and increasing moisture, some instability will build along and ahead of the cold front. A weak trough will provide upper level support, allowing a risk of strong to severe thunderstorms during the afternoon and evening. Thunderstorms will likely be supercells or organized thunderstorm clusters. Due to the weak wind shear leading to the potential for supercells, there will be a low risk for tornadoes, along with a risk for damaging winds.

A Look Ahead
Model guidance continues to agree that a strong area of low pressure will develop across the Central Plains on Saturday which will allow a frontal boundary to stall over the Midwest into the Great Lakes. Widespread showers and thunderstorms will likely develop along the front for much of the afternoon into the overnight hours. Rainfall amounts in excess of 3 inches  with locally higher amounts are forecast. Confidence is low regarding totals and will likely be refined in the coming days.
