Midwest Storm Setup

The culprit is a potent jet stream dip that will move across the northern Rockies and into the Plains. This will help to propel a strong frontal system through the Midwest Thursday through Saturday.
Impacts will range from huge temperatures drops to gusty winds, thunderstorms and perhaps even some snow.

Potential Late Week Storm Impacts

Mild Tuesday

Much Cooler Friday

Impact #1: Huge Temperature Drops
The most certain impact from this frontal system will be the very large temperature drops. In some places, high temperatures will drop 25 or more degrees from the start to the end of the week.
Here's a few examples:

• Denver and Rapid City, S.D.: After starting the week with temperatures in 60s, 70s and even low 80s, highs may not get out of the 40s and low 50s in these areas on Friday.
• Minneapolis: Highs in the upper 70s to near 80 through Wednesday will plummet into the 50s by Saturday.
• Kansas City: Highs in the low 80s through Thursday will crash into the 50s and 60s this weekend.
• Chicago: Afternoon temperatures in the 70s and low 80s through Friday will be replaced by 60s this weekend.
