FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO  
NATIONAL WEATHER SERVICE DENVER/BOULDER CO  
515 AM MDT FRI AUG 23 2019  
   
DISCUSSION...TODAY AND TONIGHT
 
AN UPPER TROUGH WILL MOVE  
ACROSS THE CWA TODAY INTO THIS EVENING. THERE WILL BE PLENTY  
OF MOISTURE AROUND AND SOME ENERGY FOR A CHANCE OF AFTERNOON  
AND EVENING SHOWERS AND THUNDERSTORMS, MORE SO EAST OF THE  
CONTINENTAL DIVIDE WITH THE BEST CHANCES OVER THE EASTERN  
PLAINS. THE AIRMASS WILL BE A BIT COOLER TODAY WITH AFTERNOON  
HIGH TEMPERATURES RIGHT AROUND SEASONAL NORMALS.  
 
LONG TERM DISCUSSION...SATURDAY THROUGH TUESDAY...WARMER AND DRIER  
AIR WILL MOVE INTO THE AREA OVER THE WEEKEND. SATURDAY WILL SEE  
INCREASING FIRE DANGER, AND THEN SUNDAY WILL BE A LITTLE WARMER,  
DRIER AND WINDIER. THE MAIN CONCERN WILL BE THE NORTHERN MOUNTAIN  
VALLEYS WHICH WILL BE NEAR RED FLAG CONDITIONS ON SATURDAY AND  
THEN HAVE WORSE CONDITIONS ON SUNDAY. OTHER MOUNTAIN AREAS WILL  
ALSO HAVE STRONG WINDS ON SUNDAY WHEN GUSTS BETWEEN 20 AND 40 MPH  
WILL BE COMMON WITH HUMIDITIES IN THE TEENS. FOR AREAS EAST OF THE  
MOUNTAINS, IT WILL BE WARMER AND DRIER ON SATURDAY BUT WINDS WILL  
BE LIMITED TO THUNDERSTORM OUTFLOWS AND AREAS NEAR THE EASTERN  
BORDER WITH HIGHER HUMIDITIES. ON SUNDAY, CONDITIONS WILL BE WORSE  
ON THE PLAINS WITH LOWER HUMIDITIES AND BREEZY CONDITIONS IN THE  
AFTERNOON, ESPECIALLY NEAR THE NORTHERN BORDER.  
 
FOR THE EARLY PART OF NEXT WEEK, THE MOUNTAINS WILL REMAIN WARM  
AND DRY BUT WITH LESS WIND. THE WINDS MAY INCREASE AGAIN ON  
WEDNESDAY OR THURSDAY. EAST OF THE MOUNTAINS IT WILL BE A BIT  
COOLER WITH HIGHER HUMIDITIES.  
 
...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...
