Severe thunderstorms are expected over portions of the Upper/Middle Mississippi Valley today, May 19, 2022, and over Midwest and Southern Plains on Friday, May 20.

A deep upper-level trough and retrograding ridge in the western Atlantic will drive much of the significant weather across the lower 48 over the next couple of days, NWS forecaster Kebede noted.1

Heavy rain and scattered to isolated thunderstorms will focus between a pair of warm fronts extending across the Northern Plains and Upper Midwest today. As a result, a Slight Risk of flash flooding is in effect for portions of northeastern North Dakota and Northwestern Minnesota.

Severe thunderstorms capable of producing supercells with large hail, tornadoes and wind damage are possible over portions of Iowa, Wisconsin and southeastern Minnesota where a Slight Risk with an embedded Enhanced (level 3/5) is in effect for this afternoon/evening.

Downstream, another system will produce showers and thunderstorms across the Tennessee Valley and southern Mid-Atlantic.

A Slight Risk of severe thunderstorms is in effect for a swath of land extending from eastern Missouri to coastal Carolina, where isolated large hail, a tornado or two and damaging wind gusts are expected.

Meanwhile, heavy mountain snow will spread from the Northern Rockies down to the Colorado Rockies beginning today.

15 – 25 cm (6-10 inches) of snow with locally higher amounts are possible for the aforementioned areas by Saturday morning.

Winter Storm and High Wind Warnings are in effect for portions of west-central Montana.

A cold airmass will dive into the Rockies and Northern/Central Plains on the backside of the upper trough responsible for producing the heavy mountain snow.
