Heat advisory: Lamar to reach 106 Monday before midweek cooldown in Prowers County
A heat advisory is in effect for Lamar and the Prowers County area from 9 a.m. to 8 p.m. Monday as temperatures soar to a high near 106 under sunny skies. Relief arrives Monday night, when a strong cool front drops Tuesday's high into the upper 80s and brings thunderstorm chances to the area through midweek.
Monday will be sunny, hot, and breezy, with an east-southeast wind of 10 to 20 mph becoming south in the morning. Monday night carries a 30 percent chance of showers and thunderstorms, mainly before 11 p.m., with a low around 64. Winds shift to the north at 20 to 25 mph after midnight behind the front, with gusts as high as 35 mph.
“HOT. Records will likely be tied or broken today at the 3 primary sites,” Stephen Hodanish, a meteorologist with the National Weather Service in Pueblo, wrote in Monday's Area Forecast Discussion, noting Pueblo is forecast to reach 105 against a record of 103. Hodanish said the cool front will cross the region Monday evening and push into New Mexico during the overnight hours, with winds turning gusty behind it.
Dangerous heat Monday, then a sharp cooldown
Monday's high near 106 makes for the hottest day of the week and dangerous conditions for anyone outdoors during the afternoon. The heat advisory runs from 9 a.m. to 8 p.m. Forecasters said winds should stay relatively light during the day, keeping critical fire weather conditions at bay, though the combination of heat and dry vegetation still warrants caution. By Tuesday, highs fall nearly 20 degrees, with the Pueblo office noting the plains may not climb above 90 anywhere in the region.
