Lamar swelters through a string of 100-degree days with gusty winds and storm chances
Lamar faces four consecutive days of triple-digit heat this week, starting with a high near 104 Monday, according to the National Weather Service in Pueblo. Highs hold at or above 100 through Thursday while gusty winds build at midweek and thunderstorm chances arrive Tuesday night onward.
Monday will be sunny and hot, with light and variable winds becoming east southeast at 10 to 15 mph in the afternoon. Monday night will be clear, with a low around 67. No heat advisory is in effect for Prowers County, though the weather service has issued one for El Paso and eastern Fremont counties.
"Hotter weather over the region," Stephen Hodanish, a meteorologist with the National Weather Service in Pueblo, wrote in Sunday's Area Forecast Discussion, forecasting highs in the 100s along the lower Arkansas River valley from Canon City east to the Kansas border.
Prolonged heat, gusty winds raise fire concerns
Monday's 104-degree high begins a stretch of readings of 101 Tuesday, 100 Wednesday and 102 Thursday. Winds turn gusty as the heat continues, with gusts to 30 mph Tuesday and 35 mph Wednesday afternoon and Wednesday night.
No fire weather warnings are in effect for Prowers County, but the combination of triple-digit heat, gusty winds and drought that the weather service says continues to deepen across southeast Colorado can allow any fire that starts to spread quickly. Thunderstorm chances offer some relief, rising to 30 percent Wednesday night and 40 percent Thursday night.
