Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
522 AM MST Mon Dec 18 2017

.DISCUSSION...Today and tonight...Warmer weather and lower
humidities can be expected through tonight as a flat ridge of high
pressure builds over the area. Gusty westerly winds can be
expected in the foothills, as well as the northern border area
today where fire danger will be elevated. Elsewhere, winds will
be lighter. Smoke dispersion will be fair to good in most areas
during peak heating today, but still limited to poor in some
valley locations.

LONG TERM DISCUSSION...Tuesday through Friday...Upper level
ridging will dominate the weather through Wednesday with moderate
westerly flow aloft, a dry airmass and warmer than normal
temperatures. A cold airmass moves in Thursday along with a
chance of snow. Temperatures will be below normals Thursday and
Friday.

       ...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...
