Triple-digit heat builds for Lamar, Prowers County, with elevated fire weather
Lamar and Prowers County face the hottest stretch of the region this week, with sunny skies, breezy winds and highs near 99 Monday and Tuesday, climbing to around 100 on Wednesday. The National Weather Service in Pueblo expects thunderstorm chances to increase midweek as moisture builds, offering a brief break before hot, dry conditions return.
Monday is sunny and breezy, with a high near 99. A south-southeast wind of 5 to 10 mph increases to 15 to 20 mph in the afternoon, with gusts as high as 35 mph. Monday night is mostly clear with a low around 65 and a breezy southeast wind of 15 to 20 mph.
A meteorologist with the National Weather Service in Pueblo wrote in Sunday's Area Forecast Discussion that "a slow increase in available moisture brings an increase in daily shower and thunderstorm coverage through the middle of the week," with a much warmer and drier pattern setting up for the weekend.
Heat and wind raise fire concern
With highs near or above 100 and afternoon wind gusts to 35 mph early in the week, fire weather conditions across the lower Arkansas River Valley will be elevated even though no formal Red Flag Warning has been issued for Prowers County. Dry vegetation, low afternoon humidity and gusty winds mean any spark could spread quickly, and residents are urged to use caution with equipment and open flames. Storm chances build Tuesday night and midweek, with slow-moving storms capable of gusty winds, lightning and brief heavy rain.
