Lamar braces for breezy, wet stretch with Friday night freeze possible
Lamar and the rest of Prowers County are expected to see a breezy, wet stretch from Wednesday afternoon through Friday morning, followed by a possible freeze Friday night and a sunny, warming weekend, according to the National Weather Service forecast office in Pueblo.
Wednesday is mostly cloudy with a 30 percent chance of showers, mainly after 5 p.m., the Lamar forecast says. The high is expected near 70 degrees. The day will be breezy, with a light southeast wind shifting to south-southeast at 15 to 20 mph through the morning. Showers and thunderstorms become likely Wednesday evening as a strong storm system moves into the region, with the chance of precipitation rising to 80 percent overnight.
"Cooler and wetter weather Thursday through Friday, with moderate to heavy snowfall across the higher terrain, especially over and near the southeast mountains," the Pueblo forecast office wrote in Wednesday's Area Forecast Discussion. Forecasters added that there is "potential for a widespread freeze across the southeast plains Friday night," a concern that includes Prowers County.
Storm system, then freeze threat Friday night
Thursday is expected to be the coolest day of the work week for Lamar, with steady showers, possible afternoon thunderstorms and a high only near 53. East winds of 10 to 15 mph are forecast. Rainfall amounts of a tenth to a quarter inch are possible across the day, with locally higher totals in any thunderstorm.
Friday brings a 70 percent chance of showers, a high near 58 and a wind shifting from the east-northeast to south-southeast in the afternoon. As the system pulls away Friday night, skies are forecast to clear and the low is expected to drop to about 30 degrees in Lamar — well below freezing. Producers across Prowers County should prepare for potential frost and freeze damage to early-season vegetation, irrigation infrastructure and livestock watering systems.

Thursday and Friday at a glance
Drivers along U.S. 50, U.S. 287 and U.S. 385 should plan for wet pavement, reduced visibility and gusty crosswinds Wednesday afternoon and through Thursday. Travelers heading west toward Pueblo or up the I-25 corridor should also be aware of winter-storm-grade conditions in the higher terrain to the west, where the Pueblo office has issued Winter Storm Watches for portions of the eastern mountains.
No fire weather watches or warnings were in effect for Prowers County as of Wednesday morning. The Pueblo office's most recent Red Flag Warning, in place over the weekend for parts of southeast Colorado, has expired, and the cooler, wetter pattern through Friday will continue to lower fire danger across the plains.
Weekend outlook
A warming and drying trend is on tap for Saturday into early next week as upper-level ridging rebuilds across the Rockies. Lamar can expect sunny skies and a high near 71 on Saturday, climbing to about 80 on Sunday with light southwest winds. Overnight lows recover from the mid-30s Saturday into the upper 30s by Sunday night.
Residents should monitor forecast updates closely Friday for the freeze potential, particularly for tender plants, garden beds and any irrigation systems already in service for the season.
