Severe potential across eastern Nebraska by Monday afternoon; main threat of destructive hail, tornadoes

Monday starts out very warm, sticky-humid and windy. Cloud cover and spotty drizzle will gradually clear toward the afternoon and set the stage for the possibility of severe weather across eastern Nebraska.

A Slight (Level 2 of 5) to Enhanced (Level 3 of 5) risk of severe weather highlights eastern Nebraska Monday, increasing in the risk of severe weather as you go east. The window for quick-developing, strong to severe storms *if* they form will be about 2PM-6PM Monday afternoon and evening.

Here’s a reminder of what each severe risk category means:

Strong tornadoes are possible, but the best chance for EF-2 or greater tornadoes is into western Iowa.

Destructive hail will be one of the main threats, too. Potential sizes could be up to 2-3″ in diameter.

Gusty winds could be up to 60-70 mph as well with storms.

Here’s the latest timing from Stormcast as of Monday morning. While not a guarantee, any storms after about 2 p.m. Monday will threaten severe weather in eastern Nebraska, moving northeast if they form.

Many models this morning still showed no storms forming in eastern Nebraska with a lack of some ingredients, and while that scenario is certainly possible as well, we’ll be monitoring for this conditional threat of severe weather through the day.

IMPORTANT NOTE: The NOAA weather radios will be down for Monday’s potential severe weather event. This is part of a required, scheduled update to their Advanced Weather Interactive Processing System (AWIPS) through Wednesday, April 30.

The following transmitters will be affected:

• KIH-61 Omaha, NE
• WXM-20 Lincoln, NE
• WXL-77 Carrol, NE
• KWN-41 Shubert, NE
• KZZ-69 Beatrice, NE
• WNG-549 Columbus, NE
• WNG-645 Albion, NE

Have multiple OTHER ways to receive warnings should severe weather move into your area Monday afternoon/evening.
