Still hot with widely scattered severe potential in eastern Nebraska

After a day of triple-digit heat across Nebraska and tying the record high from the 1900s in Lincoln, we’ll still be quite hot and humid this Tuesday.

A Heat Advisory will be in effect by 1 p.m. Tuesday afternoon and last through the evening.

Heat index values could be as high as 108° across southeast Nebraska with the muggy conditions.

A cold front is expected to potentially drive some very scattered storms by the late afternoon. There is a better chance to see these storms today rather than yesterday.

Storms – that should have less warm air aloft than yesterday – will develop in northeast Nebraska and move east and south tonight. There’s still some uncertainty with placement of these storms across eastern Nebraska, and not everyone will see them.

That front won’t bring much relief from the heat, but highs on Wednesday will drop to the upper 80s and lower 90s.

The latest update from the Storm Prediction Center has a Slight (Level 2 of 5) risk across eastern Nebraska for potential scattered, severe storms.

Initially, the primary threat will be very large hail. Up to baseball size hail will be possible as storms initially form and organize in northeast Nebraska and in the area of black hash marks below.

There is also a low-end threat for an isolated tornado or two in the green area below.

And damaging winds will be a threat if storms move into southeast Nebraska after about 7 p.m. Tuesday.

Generally, we’ll trend in a cooler direction for Wednesday – and especially by Thursday.

Highs in the lower 80s by then will feel much better than how we started out this week.
