THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL  
COLORADO.  
   
DAY ONE
 
TODAY AND TONIGHT  
 
ANOTHER HOT DAY IS IN STORE FOR US, ALTHOUGH THERE MAY BE ISOLATED  
SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING TO OFFER UP  
SOME SLIGHT COOLING. IF A STORM CAN DEVELOP OVER THE NORTHEAST  
CORNER OF THE STATE, IT MAY BE BRIEFLY SEVERE WITH STRONG WINDS,  
HEAVY RAINFALL, AND SOME HAIL. OVER THE REST OF THE PLAINS, ANY  
ISOLATED SHOWERS AND STORMS WOULD PRODUCE ONLY A BRIEF PERIOD OF  
LIGHT TO MODERATE RAIN AND GUSTY WINDS AROUND 40 MPH.  
 
THERE IS A LIMITED THREAT OF FLASH FLOODING IN THE CAMERON PEAK  
AND EAST TROUBLESOME BURN AREAS, WHERE A STRONGER STORM COULD  
PRODUCE A HALF INCH OF RAIN IN 30 MINUTES THIS AFTERNOON AND  
EVENING.  
   
DAYS TWO THROUGH SEVEN
 
FRIDAY THROUGH WEDNESDAY  
 
MOISTURE WILL BEGIN TO INCREASE ON FRIDAY, WITH AN ELEVATED  
THREAT OF FLASH FLOODING IN BURN AREAS. IT WILL BE ANOTHER HOT  
AFTERNOON WITH HIGH TEMPERATURES IN THE MID 90S. THE THREAT OF  
FLASH FLOODING WILL LIKELY FURTHER INCREASE BY SATURDAY AS A COLD  
FRONT AND SURGE OF MONSOONAL MOISTURE ARRIVE. THE BURN AREAS IN  
THE MOUNTAINS AND FOOTHILLS WILL BE MOST SUSCEPTIBLE TO THE  
FLOODING IMPACTS, HOWEVER THE I-25 CORRIDOR AND ADJACENT PLAINS  
MAY ALSO SEE HEAVY RAIN AND LOCALIZED FLOODING.  
 
THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL DECREASE ACROSS THE  
PLAINS AND I-25 CORRIDOR EARLY NEXT WEEK, BUT THERE WILL STILL BE  
HEAVY RAINFALL POSSIBLE ALONG WITH THE THREAT OF FLASH FLOODING  
IN THE BURN AREAS.  
   
SPOTTER INFORMATION STATEMENT
 
 
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
