Today will be warm across the plains. Critical fire weather conditions are possible for the plains east of I-25, especially for locations that did not receive significant rainfall on Monday. Winds will be breezy for the plains and windy in the mountains. A cold front will move through overnight bringing more gusty winds.
Very warm temperatures, low humidity, and gusty winds this afternoon will result in an environment favorable for rapid fire spread over the plains of northeastern Colorado, particularly for areas that have not received significant rainfall and sufficient green-up. A Red Flag Warning is in effect from noon to 8 pm for relative humidity in the low teens and west winds expected to gust into the 30-40 mph range, strongest near the Wyoming border.
Dry weather through most of Saturday, then an increasing chance of showers and storms by Saturday night and Sunday. Warmest temperatures today and then again Friday into Saturday. More significant cooldown with springlike temperatures expected by Sunday.
