120 FNUS55 KBOU 202106 FWFBOU Fire Weather Forecast for Northeast and North Central Colorado National Weather Service Denver/Boulder CO 306 PM MDT Mon May 20 2024 .DISCUSSION...Tonight and Tuesday...A cooler and unsettled weather pattern will be over the forecast area with scattered showers and thunderstorms, and even some snow showers over the mountains. Humidities will be higher. Sufficient mixing and heating should still allow for good or very good smoke dispersal in the mountains, but only fair to good on portions of the plains. LONG TERM DISCUSSION...Tuesday night through Saturday... Fire weather conditions could reach elevated conditions Thursday. A short lived dry period will occur and relative humidities drop between 12-16 percent along South Park, the Palmer Divide, and adjacent plains. Southerly winds could increase producing periodic wind gusts up to 20-30 mph for these areas. Given the ongoing green up period, this will likely keep conditions elevated. Fire weather conditions should remain low Friday into the weekend due to isolated to scattered showers and storms. Smoke dispersal conditions range from very good to excellent Wednesday and Thursday across northeastern Colorado. ...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...
