Extreme heat warning, then severe potential across Nebraska through late Tuesday night

We will be just as hot as the past couple days in Lincoln, a third day of temperatures in the middle and upper 90s wearing on us.

Lincoln and Omaha are within the six counties to be upgraded to an Extreme Heat Warning for Tuesday afternoon. That will be in effect from noon until 8 p.m. Tuesday night. The heat index will be around 110-115° again.

Elsewhere in southeast Nebraska, a Heat Advisory is in place for a heat index in the lower 100s expected. This has been an update since our morning show.

Grueling triple-digit “feels like” temperatures will be the case all afternoon. Another day of July summer heat and humidity!

Each location across southeast Nebraska will climb between 100-115° during the hottest part of the day.

A FLOOD WATCH is in effect starting at 6PM this evening through 10AM Wednesday morning. Excessive rainfall with thunderstorms could cause flooding in low lying areas through tonight.

We get really hot and humid ahead of another cold front that is expected to drive some stronger storms through the state today. Starting up this afternoon, storms race out of Colorado and out of South Dakota, merging in Nebraska tonight.

Timing is late and overnight again for southeast Nebraska.

We’ll have to be mindful of any back building storms, too, as localized instances of flash flooding could be possible once again.

There is a risk for severe weather with practically all these storms as they get going Tuesday afternoon and evening. A Slight (Level 2 of 5) risk paints basically all of Nebraska for possible scattered severe storm potential.

The main concern with severe weather this time around will be a damaging wind threat along with some heavy rainfall. The black hash mark area below that starts around Ogallala up toward Hyannis in western Nebraska traces I-80 and areas just north for a chance at damaging wind gusts that could be 75 mph or higher with storms later today.

There’s some hail potential initially, mainly out in western Nebraska.

Some storms will linger in southeast Nebraska early on Wednesday, but this event and that cold front will drag temperatures down to around 80 on Wednesday and the 70s the rest of the week with a drop in humidity.
