FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO  
NATIONAL WEATHER SERVICE DENVER/BOULDER CO  
346 AM MDT WED JUN 3 2020  
   
DISCUSSION...TODAY AND TONIGHT
 
IT WILL BE ANOTHER HOT  
AFTERNOON WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS.  
THE BEST CHANCE FOR STORMS WILL BE OVER THE FAR NORTHEAST CORNER  
OF THE STATE. ONE OR TWO STORMS THERE COULD PRODUCE BRIEF BUT  
VERY STRONG WIND GUSTS TO 60 MPH. RELATIVE HUMIDITIES WILL STAY  
ABOVE 15 PERCENT WITH GENERALLY LIGHT WINDS SO FIRE DANGER WILL  
BE LOW. THE THUNDERSTORMS WILL TAPER OFF FROM WEST TO EAST THIS  
EVENING WITH PARTIAL CLEARING OVERNIGHT. DISPERSAL WILL BE GOOD  
TO EXCELLENT IN MOST AREA BY EARLY AFTERNOON.  
 
LONG TERM DISCUSSION...THURSDAY THROUGH SUNDAY...HIGH PRESSURE  
CENTERED OVER THE ROCKIES WILL BRING VERY WARM AND MAINLY DRY  
CONDITIONS THURSDAY AND FRIDAY. ISOLATED TO SCATTERED  
THUNDERSTORMS ARE EXPECTED THURSDAY AND FRIDAY. DUE TO LIMITED  
MOISTURE, THIS ACTIVITY WILL BRING MORE WIND THAN RAIN. STRONG  
SOUTHERLY WINDS ARE EXPECTED FOR SATURDAY AND SUNDAY AS THE HIGH  
MOVES OFF TO THE EAST. A PACIFIC STORM SYSTEM MAY BRING SHOWERS  
AND THUNDERSTORMS TO THE AREA FRIDAY NIGHT AND SATURDAY. THE BEST  
CHANCE FOR RAIN WILL BE OVER THE MOUNTAINS AND FOOTHILLS. IT WILL  
DRY OUT BEHIND THIS SYSTEM FOR SUNDAY.  
 
...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...
