Weather Alerts For Castle Pines, CO

URGENT - FIRE WEATHER MESSAGE National Weather Service Denver/Boulder CO 231 AM MST Thu Dec 18 2025 ...CRITICAL FIRE WEATHER CONDITIONS THURSDAY AND FRIDAY... Strong northwest winds will spread across the northeast plains after sunrise today, with gusts 45 to 65 mph creating critical fire weather conditions despite somewhat marginal humidity values near 20%. Early Friday, westerly downslope winds will bring strong gusts to the Front Range mountains and foothills, with potential for these to spread into wind-favored portions of the adjacent lower elevations. Peak gusts of 70-90 mph are increasing in likelihood for the windiest locations (considerably lower for areas along and east of I-25). With a warmer and drier air mass in place, humidity values in the teens look to extend into much of the foothills, and certainly across the lower elevations. Such conditions may be a longer duration than usual, with potential for low humidity to extend into the evening hours prior to the arrival of a front.
