ZONES 486, 487 AND 490...
...RED FLAG WARNING IN EFFECT FROM NOON UNTIL 8 PM MDT FRIDAY FOR
GUSTY WINDS, LOW HUMIDITY AND DRY FUELS FOR COLORADO FIRE WEATHER
ZONE 203 BELOW 6000 FEET, AS WELL AS UTAH FIRE WEATHER ZONES 486,
487 AND 490...
.DISCUSSION...Well above normal temperatures into Friday will lead
to deep mixing and promote gusty afternoon winds and low humidity
in the single digits and teens. This will lead to critical fire
weather conditions where fuels are dry. Temperatures and winds will
be trending downward through the weekend with critical fire weather
areas becoming more localized. Afternoon showers will be possible
but winds are more likely than wetting rainfall.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
...THE SMOKE DATA IS CALCULATED FROM AN AVERAGE AT 6000 FEET MSL...
