GOLDEN VALLEY, Minn. - Storm chances will continue across central and southern Minnesota into western Wisconsin Wednesday afternoon and evening. Atmospheric conditions both at the surface and into the upper levels are favorable for storm development.
Tonight's Aquatennial Torchlight Parade in downtown Minneapolis doesn't look like a washout, but parade-goers should be ready for spotty showers or non-severe thunderstorms.
Here at ground level, good old fashioned convection and plenty of muggy air will fuel storm development. This is especially true for southern Minnesota where midday temperatures are already nearing 90°. Dew points across the southern third of the state were near 70°, signifying a very humid environment.
In the upper atmosphere a low pressure trough has been developing over South Dakota. As that feature pushes eastward, it will continue to bring a wind shear environment that also supports the storm development.
There is good news with this rain event... we need the rain! The storms also bring a much cooler day for us with temperatures staying out of the 90s for much of the state. Looking ahead, we have another slightly cooler day on tap for Thursday before the 90s return for Friday and the upcoming weekend.
