Extreme Heat and Severe Storms of August 26, 2024 (2024)

Storm 1 Monday Evening

The pictures below show hourly radar images of the first storm as it moved across the region. This storm intensified between 6 and 7 pm as it approached the west Metro.

Radar reflectivity (left) and velocity (right) at 5:00 pm on August 26, 2024. At this time, storms were developing across west central Minnesota	Radar reflectivity (left) and velocity (right) at 6:00 pm on August 26, 2024. At this time, storms continued across west central Minnesota, but started to develop a cold pool.	Radar reflectivity (left) and velocity (right) at 7:00 pm on August 26, 2024. At this time, the cold pool was well established, and the outflow boundary can be seen as a fine line in the reflectivity out ahead of the main convection. There are a few pockets of bright green that indicate higher velocity, and coincides with the widespread tree damage that was ongoing in the west metro. The Flying Cloud airport measured a 63 mph wind gust.

Radar reflectivity (left) and velocity (right) at 8:00 pm on August 26, 2024. At this time, the transition to a bow echo was nearly complete. The strongest winds are shown in the brighter red colors, because these winds are moving away (from west to east) from the radar.	Radar reflectivity (left) and velocity (right) at 9:00 pm on August 26, 2024. At this time, the bow echo is mature with strong outbound winds evident in the velocity. However, keep in mind that as the storm moves away from the radar, the sampling elevation of the radar is higher above the ground and less likely to represent the observed winds at the surface.	Radar reflectivity (left) and velocity (right) at 10:00 pm on August 26, 2024. At this time, the storm is exciting the forecast area and moving into central Wisconsin.
