Thunderstorms in Upper Mississippi & Heavy Rain in Southwest - 10-28 to 10-30
Updated Wed Oct 28th 2026, 7:31am PDT

Weather patterns are bringing a mix of storms across different parts of the country. The Upper Mississippi Valley is expecting severe thunderstorms, while Cascades and other mountain regions will see snow. In the Southern High Plains and Southwest, heavy rain is on the way, increasing the risk of flash flooding. Let's dive into the details for each region.

Thunderstorms in the Upper Mississippi (Wed)

On Wednesday afternoon, the Upper Mississippi Valley will face some strong storms. These can bring severe thunderstorms with the possibility of damaging winds and large hail. Rainfall could be intense at times, so keep an eye on local warnings if you're in this area.

Snow in the Cascades and Northern Rockies (Wed)

For those in the Cascades and the Northern Rockies, expect snow over higher elevations on Wednesday. The cooler storm track above these mountain regions means snow instead of rain in these spots. Be cautious if traveling through mountainous roads.

Heavy Rain in Southern High Plains (Thu-Fri)

Rain Continues in the Northwest (Fri)

By Friday, another front hits the Pacific Northwest, bringing rain and some more snow in high elevations. The same day, moisture from the Gulf of California will reach the Southwest, leading to thunderstorms and a risk of flash flooding. Southeastern California will also witness some showers and storms.
