Colorado Weather Alert: Frost Advisory Issued for San Luis Valley as Temps Drop Into 30s

PUEBLO, Colorado — The National Weather Service in Pueblo has issued a Frost Advisory for the San Luis Valley through 9 a.m. Thursday, warning residents of overnight temperatures dropping to between 33 and 36 degrees. Clear skies and light winds created ideal conditions for frost formation, leaving gardens and crops vulnerable.

Farmers and Gardeners Urged to Protect Plants

Communities including Alamosa, Antonito, and Creede experienced some of the coldest spots overnight, with near-freezing temperatures threatening outdoor plants. The NWS urged residents to cover or bring inside sensitive vegetation until mid-morning warming eased the frost risk.

Temporary Warm-Up Ahead, but More Frost Possible

The frost advisory will expire later this morning as sunshine pushes highs into the 60s and 70s. The next two nights are expected to be warmer, providing a short break for growers. However, forecasters cautioned that another round of near- or below-freezing temperatures could return by Sunday morning, signaling more challenges for the region’s farmers and gardeners.

Community Reporting Encouraged

The NWS advised residents to monitor updated forecasts and to report frost damage to local extension offices. Sharing conditions on social media can also help track early-season cold impacts across the San Luis Valley.

With the growing season nearing its end, residents in southern Colorado are bracing for more cold snaps that could affect crops and gardens. For more weather alerts and regional updates, follow ChicagoMusicGuide.com.
