Lamar nears 102 Saturday as heat peaks across Prowers County
Lamar climbs to a high near 98 Friday and then to about 102 Saturday and 100 Sunday, the hottest stretch of the five-day forecast, according to the National Weather Service in Pueblo.
Friday is sunny in the Lamar vicinity with a high near 98. A southeast wind of 10 to 15 mph turns south-southwest during the morning. Friday night is mostly cloudy, then gradually mostly clear, with a low around 68 and a wind shifting to the southwest after midnight.
Stephen Hodanish, a meteorologist with the National Weather Service in Pueblo, wrote in Friday's Area Forecast Discussion that highs Saturday and Sunday will be “pushing around 100F” along the lower Arkansas River valley from Pueblo east to the Kansas border. Strong southwesterly flow develops over the region through Monday, he wrote, carrying moisture picked up from tropical systems over the Pacific along with the ongoing monsoon.
Triple-digit heat Saturday and Sunday
Saturday is the hottest day of the period in Prowers County, with a high near 102 under sunny skies and a 10 percent chance of showers and thunderstorms after 5 p.m. Sunday is mostly sunny and hot with a high near 100.
No red flag warnings or fire weather watches covered Prowers County as of Friday morning, and the Pueblo office listed no watches, warnings or advisories. Even so, hot afternoons, low humidity and dry fuels warrant caution with anything that can throw a spark. The weather service continues to report moderate to exceptional drought across south-central and southeastern Colorado.
Rain chances improve late in the period. Forecasters put the chance of showers and thunderstorms at 40 percent Sunday night before midnight and 40 percent Monday night, mainly before midnight, as a boundary moves down the plains.
