Heat, heat and some more heat
Impressive temperatures throughout southeast Nebraska on Monday afternoon.
Records were broken in Lincoln and Hastings. Heat indices rose well above 100 late afternoon.
Lincoln reached 103 on Monday, establishing a new record high for the date. The previous record was 102, set in 1952.
Hastings topped out at 103, breaking the previous record of 100, also set in 1952.
The number that is arguably more important, the heat index, reached 107 on Monday afternoon in Lincoln. This is the highest heat index in 10 months and 4 days.
Of note, this is only the fourth day to produce a 107-degree heat index in the city in the last three years.
Heat is going to stay around the region for the next several days.
In fact, not one day out of the next 10 are projected to have at or below normal temperatures. This will make up for the cool start to June.
Winds will increase out of the south late Monday night, with sustained winds of 10-20 mph and gusts to 30 mph. Tuesday morning should start out windy, with gusts to 35 mph.
A weak cold front will attempt to move through southeast Nebraska on Tuesday.
It will likely stall about halfway through the region. Behind the front, winds will shift to the northwest, and temperatures will top out in the upper 80s to lower 90s.
Ahead of the cold front, temperatures will climb into the middle to upper 90s.
Heat indices ahead of the front should climb to the upper 90s to lower 100s on Tuesday afternoon.
Later Tuesday night, thunderstorms will begin to pop near the front.
They should intensify during the late-night hours (after 11 p.m.) and drift to the north.
A few of these thunderstorms could be strong to severe, with the main threat being damaging wind and large hail.
There remains some question as to the exact location of the storms.
Some data suggests that the storms pop and remain north of Interstate 80. Other data suggests they develop over I-80 and then move north.
We’ll continue to update the location as more data becomes available.
