Hail Up to 2 Inches Plus Targeting Kansas and Oklahoma Including Wichita, Topeka and Tulsa With Pocket Change Hail Across Iowa, Illinois and Indiana Monday Evening 5PM to 11PM
KANSAS AND OKLAHOMA — A hail potential exists today, Monday May 4, 2026, across a broad multi-state zone stretching from Kansas and Oklahoma through the Midwest along an advancing cold front. The primary threat window runs from 5 PM to 11 PM across the risk area. While most hail will remain pocket change size across the broader zone, Kansas and Oklahoma carry a notable exception with 2 inch plus hail possible where brief intense cores manage to develop.
Pocket Change Hail Possible Across Broad Midwest Zone From Iowa Through Indiana
A Level 1 five percent hail risk covers a large tan-shaded area stretching from Omaha and Sioux City through Iowa, Illinois, Missouri, Indiana, and into Michigan touching Milwaukee, Detroit, Fort Wayne, and Cincinnati.
Moisture is overall lacking across this broader zone, keeping storm forcing weak and the cap strong. Most storms that develop will produce only small pocket change hail rather than anything significant or damaging.
Kansas and Oklahoma Face 2 Inch Plus Hail Exception From Wichita Through Tulsa
The critical exception to the small hail story is the hatched zone covering Kansas and Oklahoma, where stronger surface heating and steeper lapse rates create conditions supporting very large hail exceeding 2 inches.
Topeka, Wichita, and Tulsa all sit inside this elevated hail corridor. One or two brief intense storm cores developing in this zone could produce hail well over 2 inches in diameter if they manage to break through the strong cap during the evening hours.
Threat Window Runs 5PM Through 11PM Across the Entire Risk Zone Monday
The active threat window is clearly defined from 5 PM through 11 PM on Monday, covering the peak heating and early evening hours when storm development becomes most likely along the cold front.
Residents across Kansas and Oklahoma should be the most weather aware during this window, while those across Iowa, Illinois, Indiana, and Missouri should maintain casual awareness through the evening hours. Stay with NapervilleLocal.com for the latest weather updates and local forecast coverage.
