SHORT TERM
 
(THIS EVENING THROUGH THURSDAY)  
ISSUED AT 253 PM MDT WED SEP 23 2020  
 
CURRENTLY...  
 
AN AREA OF SHOWERS AND ISOLD THUNDER WAST NOTED ALONG THE GENERAL US-  
50 CORRIDOR FROM TEXAS CREEK TO CANON CITY TO WEST OF KLHX. OTHER  
MORE ISOLD SHOWERS AND STORMS WERE NOTED ALONG THE SOUTHERN MTNS.  
OTHERWISE MOSTLY CLEAR SKIES PREVAILED ACROSS THE FORECAST AREA.  
TEMPS AT 2 PM WERE MAINLY IN THE 80S OVER THE PLAINS WITH A FEW 70S  
IN N EL PASO COUNTY. 70S PREVAILED ACROSS THE PLAINS.  
 
REST OF TODAY...  
 
DON'T THINK THE SHOWERS ON THE PLAINS WILL LAST TOO MUCH LONGER AS  
THEY MOVE SOUTHEAST DUE TO LACK OF INSTABILITY. SHOWERS OVER THE  
MTNS./PLAINS INTERFACE WILL LAST A BIT LONGER INTO THE EARLY EVENING.  
OTHERWISE. EXPECT MOSTLY CLEAR SKIES  
 
TONIGHT...  
 
RIDGE CONTINUES TO BUILD OVER THE REGION ALOFT. SKIES WILL CLEAR  
WITH MIN TEMPS IN THE 50S PLAINS, WITH WARMEST TEMPS ON THE  
IMMEDIATE EAST SLOPES OF THE MTNS. VALLEYS WILL BE IN THE 30S AND  
40S. FREEZING TEMPS POSSIBLE IN KLXV. 20S MTN TOPS.  
 
TOMORROW...  
 
SUNNY AND HOT WITH MAX TEMPS AROUND 90 MOST OF PLAINS WITH 80S ON  
THE DIVIDES; AROUND 80 VALLEYS AND 50S AND 60S MTNS.  
   
LONG TERM
 
(THURSDAY NIGHT THROUGH WEDNESDAY)  
ISSUED AT 253 PM MDT WED SEP 23 2020  
 
THURSDAY NIGHT-FRIDAY NIGHT...GENERALLY WEAK WESTERLY FLOW ACROSS  
THE REGION THURSDAY NIGHT INCREASES THROUGH FRIDAY NIGHT, AS UPPER  
LEVEL RIDGING ACROSS THE ROCKIES IS FLATTENED BY EASTERN PACIFIC  
ENERGY MOVING THROUGH THE FASTER ZONAL FLOW ACROSS THE PACIFIC  
NORTHWEST THROUGH THE NORTHERN TIER OF STATES. PATTERN SUPPORTS  
DRIER AND WARMER WEATHER ACROSS THE REGION, WITH DOWNSLOPE FLOW  
SUPPORTING RECORD TEMPERATURES FRIDAY, WITH HIGHS IN THE UPPER 80S  
TO UPPER 90S EXPECTED ACROSS THE PLAINS, AND IN THE 60S TO LOWER 80S  
ACROSS THE HIGHER TERRAIN. CURRENT RECORD HIGH TEMPERATURES FOR  
SEPTEMBER 25TH ARE 81F IN 2014 FOR ALAMOSA, 87F IN 1998 FOR COLORADO  
SPRINGS, AND 97F IN 1998 FOR PUEBLO. WARM AND DRY DOWNSLOPE FLOW  
FRIDAY WILL ALSO ALLOW FOR BREEZY CONDITIONS AND INCREASED FIRE  
DANGER THROUGH THE AFTERNOON, HOWEVER, THE STRONGEST FLOW ALOFT  
LOOKS TO STAY NORTH OF THE AREA AND LAG PEAK HEATING, WITH CRITICAL  
FIRE WEATHER CONDITIONS NOT EXPECTED TO BE MET ACROSS SOUTH CENTRAL  
AND SOUTHEAST COLORADO.  
 
SATURDAY-SUNDAY...PASSING ENERGY ACROSS THE NORTHERN TIER FRIDAY  
NIGHT SENDS A WEAK AND DRY BACKDOOR COLD FRONT ACROSS EASTERN  
COLORADO THROUGH THE MORNING HOURS ON SATURDAY. THE LATEST MODELS  
CONTINUE TO INDICATE DRY WEATHER WITH ONLY SLIGHTLY COOLER AIR  
MOVING INTO THE REGION THROUGH SATURDAY AFTERNOON, WITH THE  
"COOLEST" AIR SLOWLY SLIDING INTO THE REGION LATER SATURDAY INTO  
SUNDAY. WITH THAT SAID, HIGHS ON SATURDAY LOOK TO BE ONLY SLIGHTLY  
COOLER THAN FRIDAY'S READINGS, WITH HIGHS ON SUNDAY THEN ONLY  
SLIGHTLY COOLER THAN SATURDAY, BUT STILL ABOVE SEASONAL LEVELS IN  
THE UPPER 70S TO UPPER 80S ACROSS THE PLAINS, AND MAINLY 60S AND 70S  
ACROSS THE HIGHER TERRAIN.  
 
MONDAY-WEDNESDAY...WEAK NORTHWEST FLOW REMAINS PROGGED TO DEVELOP  
ACROSS THE REGION INTO THROUGH THE MIDDLE OF NEXT WEEK, AS A BROAD  
UPPER TROUGH CARVES OUT ACROSS THE CENTRAL CONUS AND A LARGE AREA OF  
HIGH PRESSURE BUILDS ACROSS THE WEST COAST. THIS PATTERN LOOKS TO  
KEEP DRY WEATHER IN PLACE WITH AT AND ABOVE SEASONAL TEMPERATURES  
EXPECTED ACROSS THE AREA ON MONDAY, BEFORE A STRONGER, YET STILL DRY  
COLD FRONT, PUSHES ACROSS THE REGION MONDAY NIGHT, BRINGING MORE  
SEASONAL TEMPERATURES IN THE 60S AND 70S TO AREA TUESDAY AND  
WEDNESDAY.
