Freeze watch issued for Southwest Colorado, cold snap threatens crops

The cold snap hit Dove Creek households, backyard gardens and early-season plantings with little warning, and the most dangerous window was set for late night into the pre-dawn hours Thursday. Lower-elevation communities in Southwest Colorado were expected to dip into the 20s, with temperatures around midnight likely close to freezing, leaving residents little time to bring tender plants inside, cover exposed beds and protect vulnerable plumbing before nightfall.

The National Weather Service issued a freeze watch May 6 for Cortez, Mancos, Dove Creek, Towaoc and Durango. Forecaster Dennis Phillips said the alert came earlier than usual because March was unusually warm and spring foliage got started early, which left blossoms and young shoots exposed just as the region was sliding into a late burst of cold. After Thursday morning, temperatures were forecast to rebound quickly into the 70s and 80s for the rest of the week and into early next week.

For Dolores County, the timing mattered because agriculture remains deeply tied to the local economy. The U.S. Department of Agriculture’s 2022 Census of Agriculture profile for the county listed 264 farms and 161,407 acres in farms, including 5,415 irrigated acres. Crops accounted for 65% of agricultural sales, while livestock, poultry and products made up 35%. Among the county’s leading crops were wheat for grain, safflower, forage hay and haylage, dry edible beans and barley.

The freeze watch language from the National Weather Service warns that sub-freezing temperatures are possible and can kill crops, damage sensitive vegetation and harm unprotected outdoor plumbing. That risk is especially sharp during spring radiation frosts, when Colorado State University Extension says temperatures may fall only a few degrees below critical levels. Extension guidance says floating row covers can provide up to 10 degrees of frost protection, and blankets, sheets and plastic covers can help if they are managed carefully.

The broader pattern matched what forecasters were seeing across the region. National Weather Service discussions for Grand Junction said freeze warnings were in place for most western Colorado valleys, with warmer and drier weather returning Thursday. For Dove Creek and the rest of Dolores County, the message was clear: one cold night could still erase a week of spring growth.
