SIDNEY - Just how hot was it Monday? The National Weather Service office in Cheyenne reported several cities with temperatures that rank in the top ten all-time.

Chadron set a new daily record for July 18 with a temperature of 111 degrees. The impressive high temp was also tied for the second hottest day in the city's history, with records back to 1915. 

The City of Scottsbluff had its fourth hottest day of all-time, dating back to 1893. The 108 degrees set a new mark for July 18. 

Cheyenne's record-setting 99 degrees on July 18 tied for the fifth hottest day of all-time with records back to 1872. 

Torrington (107 degrees), Sidney (106), Alliance (105) and Denver (100) all set new daily records for July 18. Torrington's previous record was 105 in 2006, Sidney's old mark in 2006 was 102, and Alliance had at temp of 103 in 2006.

It was the fourth 100-degree day of the year for Denver.

North Platte reached a high of 104 degrees, breaking the previous record of 103 set in 1936. Valentine climbed to 108 degrees. That broke the record of 105 set in 1977.

The Sidney area will have slightly cooler temperatures in the mid- to upper-90s on Tuesday, but the temps will remain above average for this time of year.

It will be very dry and breezy, so the fire danger will remain very high, according to the weather service. A red flag warning is in effect until Tuesday night for the Nebraska panhandle and southeast Wyoming. Outdoor burning is not advised and residents are asked to avoid doing any activities that could spark a wildfire.

High temperatures will remain in the upper 90s to the triple digits through Saturday.
