Another scorcher with scattered, severe potential Monday evening

Summer still trying to hold on, as is the severe weather season on Monday. Another day of scorching heat to start the first day of college courses on UNL’s campus and other area universities.

A Heat Advisory will go in effect for most of southeast Nebraska by 1 p.m. Monday. During the hottest parts of the afternoon, heat index values could be up to 110 degrees for those shaded in orange below.

An Excessive Heat Warning was upgraded for Omaha and those around the Missouri River with confidence that heat index values could be up to 113° and dangerously hot.

Prolonged heat continues as the morning temperatures don’t cool really past the mid 70s. Here in Lincoln, temperatures will rise into the lower 100s once more for the start of this new work week.

Already by 11 a.m. Monday, humidity will make it feel like the middle and upper 90s. Throughout the afternoon, temperatures will feel like 105-110 degrees in the Capital City. Stay hydrated and take breaks in the air conditioning in being cautious on a day like today.

The severe risk is significant starting Monday evening, too. There’s an Enhanced (Level 3 of 5) risk that clips areas of northeast Nebraska, just north of O’Neill. Elsewhere, a Slight (Level 2 of 5) risk comes down across western Nebraska.

Lincoln and southeast Nebraska not included in the severe threat tonight.

A 2 percent risk includes a small part of northeast Nebraska, meaning an isolated tornado cannot be ruled out with initial storms after about 5 p.m. tonight.

Large hail will also be a risk earlier in the evening with any storms across northern Nebraska. Higher confidence in hailstones 2″ in diameter if not larger for portions of South Dakota and Minnesota.

Damaging wind will be the main threat across most of Nebraska with storms coming out of eastern Wyoming and some scattered activity in southwest Nebraska.

Pay close attention to any storms that form quickly in northeast Nebraska by 5 p.m. This version of Stormcast below shows one near O’Neill during that time, but any that form like that later today will be ones to watch for all severe weather hazards.

Again, more storms coming out of eastern Wyoming will attempt to move across northern Nebraska closer to the South Dakota border as well. These storms later in the night will be more of a wind threat. More scattered storms to develop in southwest Nebraska will also threaten mainly wind.

Stay weather aware with the heat and risk of severe weather in the forecast this Monday!
