Southern Colorado Weather: Storms, Heavy Rain Develop Late Tonight

Pueblo, CO – Overnight thunderstorms could bring locally heavy rainfall and an increased risk of flash flooding to parts of southern and southeastern Colorado tonight, with the greatest storm potential lasting into the Thursday morning commute.

According to the National Weather Service in Pueblo, a cold front passing through late Wednesday is expected to help thunderstorms develop along the southern Front Range before pushing east through early Thursday.

Storms could begin as early as 10 p.m. Wednesday, while the most likely window for activity is from midnight through 7 a.m. Thursday.

Most locations can expect light to moderate rainfall overnight. However, forecasters said some thunderstorms could produce locally higher rainfall totals capable of triggering flash flooding.

The greatest concern is across southeastern Colorado, particularly in locations that have already received recent rainfall.

Forecast maps show rain extending from areas around Pueblo and Walsenburg east toward La Junta, Las Animas, Lamar and Springfield. Some portions of the southeastern plains could receive around a half-inch of rain, while locally higher amounts could occur beneath stronger storms.

Because much of the activity is expected overnight, residents may encounter changing conditions while sleeping or during early Thursday travel. The Weather Service recommends having multiple ways to receive weather warnings.

Drivers should also avoid attempting to cross flooded roads. Water covering a roadway can be deeper or faster-moving than it appears, and conditions can deteriorate quickly during heavy rainfall.

Storms are forecast to move east and gradually clear the region through the early morning hours Thursday.
