973 FNUS55 KBOU 302053 FWFBOU Fire Weather Forecast for Northeast and North Central Colorado National Weather Service Denver/Boulder CO 153 PM MST Tue Dec 30 2025 .DISCUSSION...Tonight and Wednesday... Slightly breezy tonight in the high country. Otherwise, expect lighter winds Wednesday with continued warm and dry conditions, and no fire weather concerns. Smoke dispersal will be unfavorable given the light winds. LONG TERM DISCUSSION...Wednesday night through Sunday... The plains and urban corridor will remain warm and dry through this weekend. In the high country, light snow is expected Thursday afternoon through Friday, with minor accumulations outside of the Park Range, where a few inches may accumulate. West winds look to strengthen Sunday into early next week, with uncertainty as far as their strength. There's potential for enhanced fire danger on Sunday if warmer and drier solutions verify, but there's low confidence still in the pattern beyond Saturday. Expect slight day to day improvement in smoke dispersal conditions as we enter the weekend. ...Thunderstorms imply strong gusty erratic winds... ...All surface winds are 20-Foot...10-Minute averaged winds... ...CWR is Chance of Wetting Rain - 0.10 inch or more liquid... ...24 HR Trends are based on averages over the respective zone groups and may not match the actual forecast values shown in those groups...
