Back-to-Back Pacific Storms to Impact the West Coast; Heavy Snow in the Central Appalachians

Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the 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.
