Heavy Rain and Flash Flooding in the West; Heat Expands in the Central U.S.

Monsoonal moisture will produce showers and thunderstorms with heavy rain over parts of the Southwest, Great Basin, and Central Rockies through Monday. Flash flooding is possible, especially in and around burn scars and in areas of steep terrain. Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >

Overview

Scattered severe thunderstorms developed during the afternoon of Tuesday, May 1, 2018, near and southeast of a stationary front stretching from northern Kansas, northeast through central and east-central Nebraska. Storms continued through the evening as the front slowly progressed southeast.

Hail was the main hazard from these storms, with some areas seeing large hail up to at least 2" in diameter.  Additionally, several small, fairly weak tornadoes were observed across the area (all rated EF-0). This includes brief tornadoes near Doniphan, Phillips, and Chester in Nebraska and rural southern Mitchell County KS. 

Thunderstorms lingered across parts of southern Osborne and Mitchell counties well into the evening, leading to very heavy rainfall totals and flooded roadways. Some areas received 3-5" of rain over the course of several hours, including 5.18" at a personal weather station southeast of Tipton.
