SIDNEY - Heat advisories are in effect for the Sidney area Monday afternoon as temperatures are forecast to approach record highs in the triple digits.

The National Weather Service office in Cheyenne says Dawes County could have the hottest temperature at 110 degrees. Chadron is in an excessive heat warning. 

The heat advisory is in effect for the rest of the Nebraska panhandle, northeast Colorado and southeast Wyoming from noon until 9 p.m. High temperatures will range between 99 to 107 degrees. The NWS says a few locations could approach all-time record high temperatures.

Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities, according to the weather service. They say to drink plenty of fluids and stay out of the sun for extended periods of time.

In addition to the heat advisories, fire weather watches and red flag warnings are also in effect Monday afternoon for the same area.

West to west-southwest winds at 15 to 25 mph sustained, with possible gusts to 35-45 mph by late afternoon and early evening, can contribute to extreme fire behavior. Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.

Isolated dry thunderstorms are possible on Monday afternoon and early evening.
