Lamar braces for windy Monday, midweek rain chances after weekend fire weather
After a Sunday red flag warning highlighting elevated fire weather concerns for Prowers County, Lamar moves into a week of windy, cooler weather with chances for showers and thunderstorms midweek, the National Weather Service in Pueblo said. A cold front passing late Sunday into Monday delivers a sharp drop in temperatures and gusty north winds to start the workweek.
Monday in Lamar is forecast to begin cloudy and gradually become mostly sunny, with a high near 80. North-northeast winds of 10 to 20 mph will shift to north-northwest at 20 to 30 mph in the afternoon, with gusts up to 45 mph. Forecasters at the Pueblo office indicate that the wind will be the most notable feature of the day, with travelers in high-profile vehicles urged to use caution on area highways.
Monday night will be partly cloudy and windy, with a low near 35 and north winds of 20 to 30 mph easing after midnight. Gusts could again reach 45 mph. While Lamar avoids the freeze watch in place farther north over Kiowa and Cheyenne counties, temperatures will still run well below seasonal averages.
Fire weather concerns ease as moisture returns
After Sunday's elevated fire weather conditions in Prowers County — where the Pueblo office's red flag warning highlighted gusty southerly winds and low humidity — the pattern shift behind Monday's cold front begins reducing fire danger. Cooler temperatures and rising moisture will continue to lower fire risk through midweek, although gusty winds on Monday afternoon still merit caution for anyone burning ditches or using equipment that could throw sparks.
Tuesday turns sunny and noticeably cooler, with a high near 69 and north winds of 10 to 15 mph shifting to easterly in the afternoon. Tuesday night brings increasing clouds and a 30% chance of showers after midnight, with a low near 38.
