Lamar nears 101 Friday in the week's hottest day before storms return Saturday
Lamar climbs to near 101 on Friday under full sunshine, the hottest day in a seven-day stretch of above-normal heat, with breezy conditions and better storm chances arriving Saturday, the National Weather Service says.
Friday is sunny and hot in Prowers County, with light and variable winds becoming southeast at 5 to 10 mph in the afternoon. A slight chance of showers and thunderstorms develops between 7 and 9 p.m., with a 10 percent chance of precipitation, before partly cloudy skies and a low around 64 overnight.
"Today is expected to be the hottest day of the next 7 days," a meteorologist with the National Weather Service in Pueblo wrote in Friday's Area Forecast Discussion, with plains highs running roughly 10 degrees above seasonal normals and some locations positioned to tie record highs. The forecast high at Pueblo on Friday was 100, one degree shy of the record.
Heat and wind raise fire concerns Saturday
No Red Flag Warning was in effect for Prowers County on Friday morning, and the Pueblo office listed no watches, warnings or advisories across its forecast area. Even so, the combination of triple-digit heat Friday and gusty east winds Saturday warrants caution outdoors. Saturday brings an east wind of 5 to 10 mph increasing to 15 to 20 mph in the afternoon, with gusts as high as 30 mph.
Forecasters also noted that any convection pushing off the higher terrain onto the adjacent plains Friday will likely produce mainly gusty winds because of drier air in the lower levels — outflow that can fan any fire that starts.
Beginning Saturday, monsoonal moisture returns to the region as the upper high shifts east and flattens, bringing a daily round of afternoon and evening showers and thunderstorms through Tuesday and an elevated flash flooding threat on area burn scars.
