Scattered strong to severe storms possible Monday evening in eastern Nebraska

The first day of astronomical fall is today, September 22nd. Drastic changes to the temperature happen during this season from beginning to end, as we continue to lose daylight toward the winter solstice in December.

Average high temperatures for fall start in the upper 70s, while the average low temperatures begin in the lower 50s.

We’ll be quite a bit warmer than average this first day of fall, though, especially heating up during the day.

High temperatures will warm to the middle 80s for what will likely be the warmest day of the work week. Winds will remain fairly light with mostly sunny skies.

More clouds will move in during the afternoon, and a spot shower could be seen first.

Though focus is on this first day of fall going hand-in-hand with a risk for severe weather. Stay alert later today with an increased chance for scattered strong to severe storms (a Slight, Level 2 of 5 risk) across eastern Nebraska, including Lincoln and Omaha.

The rest of the state within the Marginal (Level 1 of 5) risk in green could see some isolated stronger storms Monday.

These stronger storms in eastern Nebraska would be supported to develop by the late afternoon and evening hours beyond about 5 to 6 p.m. Monday. After those storms, another stronger storm could be sustained across eastern Nebraska just past midnight as well.

An isolated tornado cannot be ruled out as these storms are forming close to a surface low.

Large hail and damaging wind will be the main threats. Hail could be up to 1.5″ in diameter.

Wind gusts could be up to 60 mph with the stronger storms.

Showers will continue on Tuesday in what is expected to be a much cooler day. We may not even warm to 70° on Tuesday.

Beyond that, we’ll gradually warm with many dry and sunny days ahead.
