Severe Thunderstorms in the Plains & Midwest for Memorial Day Weekend
The Plains have seen an active severe weather week and that will likely continue through the Memorial Day weekend. For Saturday, the Storm Prediction Center has outlined a large severe thunderstorm risk area from the Canadian Border in North Dakota to the Mexican Border in Texas, in addition to a smaller region across the Midwest and Mississippi River Valley. Large hail and strong wind gusts are the primary threats, with a few tornadoes possible, particularly in Northern Illinois.
Strong mid-level winds will move into the High Plains around a large trough of low pressure moving through the Northwest and Great Basin. Sufficient moisture is expected to return due to good southerly flow at the lower-levels which should promote moderate to strong instability in the region during peak-heating hours.
The Storm Prediction Center has highlighted the potential for organized lines of strong storms, which are expected to move southeastward in the evening or perhaps overnight. If storms become organized in this fashion, the threat for widespread damaging downdraft winds is expected.
Snapshots of the forecast radar have been added below to help time the storms. Close-ups of the Midwest risk area are followed by an overview of the entire area.
As a cold front from this system pushes farther south and east on Sunday, the system is expected to continue to fire up strong to severe storms. There is a slight risk for severe weather in a corridor from Iowa to West Texas. Isolated tornadoes will be possible but large hail and damaging winds will likely remain the more widespread threats.
