Lamar nears 100 degrees Friday as hot, breezy Labor Day weekend settles over Prowers County
Lamar reaches 100 degrees Friday and stays in the upper 90s through Labor Day, with a breezy south wind gusting to 40 mph on the holiday and only slim chances of showers and thunderstorms through the weekend.
Friday is mostly sunny and hot in Lamar with a high near 100 and a south wind of 5 to 15 mph. A 10 percent chance of showers and thunderstorms develops after 3 p.m. Friday night turns mostly cloudy with a 20 percent chance of storms before midnight, a low around 67 and a south-southeast wind of 10 to 15 mph.
“It will continue to be hot, with highs in the 80s for the high valleys, which is about 5 degrees above normal, and upper 80s to upper 90s for the plains, which is close to 10 degrees above normal,” a meteorologist with the National Weather Service in Pueblo wrote in Friday’s Area Forecast Discussion. Forecasters placed the best storm chances along Colorado’s southern border and across the plains south of U.S. Highway 50, which includes Prowers County.
Heat and wind raise fire concerns, though no warning is posted
The Pueblo forecast office listed no watches, warnings or advisories in effect Friday morning, and no Red Flag Warning covered Prowers County or fire weather zone 236.
Conditions still warrant caution. Highs near or above 98 degrees each day through Labor Day, combined with a south wind gusting to 35 mph Sunday and 40 mph Monday, will support elevated fire danger across the dry grasslands of Prowers County. Fine fuels cured by a hot summer ignite readily under those conditions, and gusts of that strength can push a grass fire faster than crews can contain it.
