Friday will likely start off mild with temperatures in the 60s around lunchtime. But not long after that, likely around 3 p.m., thunderstorms could roll in, setting off a potentially ugly weekend of pounding snow, heavy rain and gusty conditions.
The southeastern plains - including La Junta, Limon and Springfield - could have severe thunderstorms in the afternoon and evening, according to a weather report by Gazette news partner KKTV. The area could receive hail and even isolated tornadoes.
The Pikes Peak region might see thunderstorms Friday afternoon, "but nowhere near as strong as the plains," KKTV reports. However, "the surge of moisture will lend itself to widespread rain and snowfall with temperatures falling fast enough to allow of snowfall, then accumulating snowfall across the Pikes Peak Region by mid to late Saturday morning."
According to the National Weather Service in Pueblo, Colorado Springs could see a high near 62 degrees on Friday with a 60 percent chance of showers and thunderstorms hitting the city after 4 p.m. The rain might turn into snowfall after 11 p.m., the weather service reports.
Temperatures are expected to drop significantly through the region Saturday.
The weather service predicts up to 5 inches of snow at the Colorado Springs Airport during the day before another 2 to 4 inches through the evening. A high of 37 degrees is forecast in the city.
By Sunday morning, the storm will impact the southern parts of the state but conditions are expected to taper by midday, KKTV predicts.
KKTV chief meteorologist Brian Bledsoe said the one-two punch snowstorm is slow-moving and could stay around until Monday.
The southeastern plains could receive more than 2 inches of rain. In a report, KKTV calls this "a potential drought-busting rainfall."
According to the weather service, the upper Arkansas River Basin - which feeds Colorado Springs and other surrounding communities along its path - is 7 percent higher than normal for April, and 12 percent higher than in 2015 at this time.
