This has been a week of record-setting temperatures in western Nebraska.
Several communities set daily or monthly records and some set all-time records on Tuesday.
Omaha could be on the way to setting a daily record high Wednesday, said Dave Eastlack, meteorologist for the National Weather Service in Valley.
The forecasted high for the day is 102, with a potential heat index of about 110 degrees. The daily record is 104 set in 1934, Eastlack said.
Temperatures typically reach their highest in the late afternoon, he said, around 4 p.m.
The weather service has issued a heat advisory for 1 p.m. to 9 p.m. Their goal: to remind people that they could become ill while exercising or working outdoors.
Additionally, the Douglas County Health Department is reminding people that this weather contributes to air quality problems.
The air is likely to have elevated levels of ozone, which can irritate the respiratory systems of vulnerable people.
The all-time record high for Omaha is still far off -- 114 degrees set on July 25, 1936, based on records dating to 1880.
Among communities that set all-time records Tuesday:
• McCook reached 115 degrees. Before that, the hottest it had ever gotten was 114 degrees on July 20, 1932.
• Sidney reached 111 degrees; prior to this year (because Monday also was new all-time record at 109 degrees) the hottest Sidney had ever gotten was 107 degrees, on July 16, 2006, and July 11, 1954.
Thursday is forecast to be another scorcher in the metro area, with highs currently forecast around 98 degrees.
