Lamar, Prowers County could see an inch of rain by Thursday night
Showers and thunderstorms are expected in Lamar and Prowers County through Thursday. The heaviest rain should fall Wednesday night into Thursday morning, and some areas could get an inch or more before the rain tapers off. Warmer, drier weather follows Friday and into the weekend.
Wednesday brings mostly cloudy skies, breezy south winds of 15 to 20 mph with gusts to 35 mph, and a high near 76. There is a slight chance of showers in the morning, then a 40 percent chance of showers and thunderstorms after 9 a.m. The weather service expects a tenth to a quarter of an inch of rain during the day, with more in thunderstorms.
"Given the likely efficient rain producers from this setup, flooding can't be ruled out, especially in areas that have already received moisture over the past week or so," a meteorologist with the National Weather Service in Pueblo wrote in Wednesday's Area Forecast Discussion.
Rounds of rain Wednesday night and Thursday
Rain chances climb to 80 percent Wednesday night, with showers and possibly a thunderstorm after 11 p.m. and a low around 60. The weather service expects a quarter to half an inch of rain overnight and another quarter to half an inch Thursday. Adding Wednesday's rain, some areas could see a total of roughly six-tenths of an inch to more than an inch.
Pueblo forecasters said moist southwesterly flow and a series of weather disturbances will bring the most widespread rain overnight across the far eastern plains. A Flood Watch is in effect for part of the Pueblo forecast area, but it does not cover Prowers County. No watches, warnings or advisories are in effect for Lamar. The wet, cloudy weather means no fire weather concerns this week, though the Pueblo office continues to report moderate to exceptional drought across southeastern Colorado.
