MARCH 2020 CLIMATE SUMMARY FOR DENVER, WARMER & WETTER THAN NORMAL..  
 
AFTER A COLD AND SNOWY FEBRUARY, MARCH TURNED WARMER AND DRIER. THE  
MONTH STARTED OUT SLIGHTLY COOLER THAN NORMAL AS A WEAK UPPER LEVEL  
STORM SYSTEM MOVED ACROSS THE ROCKY MOUNTAIN REGION. THIS SYSTEM  
PRODUCED LIGHT SNOW ACROSS MOST OF NORTH CENTRAL AND NORTHEASTERN  
COLORADO ON THE 1ST AND 2ND.  
 
DENVER EXPERIENCED ABOVE NORMAL TEMPERATURES FROM THE 3RD THROUGH  
THE 12TH AS AN UPPER LEVEL RIDGE OF HIGH PRESSURE DOMINATED THE  
REGION. INCREASED MOISTURE COMBINED WITH AN UPPER LEVEL DISTURBANCE  
BROUGHT MUCH NEEDED PRECIPITATION TO THE FRONT RANGE URBAN CORRIDOR  
AND ADJACENT PLAINS ON THE 8TH. MOST AREAS MEASURED BETWEEN ONE  
QUARTER TO THREE QUARTERS OF AN INCH OF PRECIPITATION WITH THE  
SOUTHERN SECTIONS OF METRO DENVER AND NORTHERN AND CENTRAL WELD  
COUNTY RECEIVING THE GREATEST AMOUNTS. MOST OF THE PRECIPITATION  
FELL IN THE FORM OF RAIN, HOWEVER HIGHER ELEVATIONS WEST AND SOUTH  
OF DENVER DID SEE SOME LIGHT SNOW.  
 
A WEAKENING STORM SYSTEM AND ASSOCIATED COLD FRONT BROUGHT COOLER  
TEMPERATURES AND LIGHT SNOW TO NORTH CENTRAL AND NORTHEASTERN  
COLORADO ON THE 13TH AND 14TH.  
 
UPPER LEVEL HIGH PRESSURE ALONG WITH A DRY SOUTHWESTERLY FLOW ALOFT  
BROUGHT A RETURN TO MILD AND DRY WEATHER FROM THE 14TH THROUGH 18TH.  
 
A POTENT STORM SYSTEM BROUGHT MUCH COLDER TEMPERATURES AND SNOW TO  
NORTH CENTRAL AND NORTHEASTERN COLORADO ON THE 19TH. HEAVY SNOW FELL  
ACROSS THE FOOTHILLS, PALMER DIVIDE AND PORTIONS OF THE PLAINS. IN  
ADDITION, STRONG WINDS COMBINED WITH THE SNOW RESULTED IN BLIZZARD  
CONDITIONS ACROSS PORTIONS OF THE PLAINS AND PALMER DIVIDE MAINLY  
EAST AND SOUTH OF DENVER. SOME FOOTHILL LOCATIONS MEASURED OVER 2  
FEET OF SNOW WITH THIS STORM WITH 5 TO 10 INCHES OF ACCUMULATION  
ACROSS METRO DENVER.  
 
ON THE 20TH, AREAS OF LIGHT SNOW CONTINUED WITH MUCH BELOW NORMAL  
TEMPERATURES. THE HIGH TEMPERATURE AT DENVER INTERNATIONAL AIRPORT  
ONLY MANAGED TO REACH 30 DEGREES FOR THE DAY WHICH IS 19 DEGREES  
BELOW NORMAL.  
 
SOME WEAK UPPER LEVEL RIDGING COMBINED WITH A WEST TO SOUTHWESTERLY  
FLOW ALOFT RESULTED IN MODERATING TEMPERATURES AND MOSTLY DRY  
WEATHER FROM THE 21ST THROUGH THE 25TH. SOME RESIDUAL MOISTURE  
COMBINED WITH DAYTIME HEATING PRODUCED A FEW AFTERNOON SHOWERS AND  
STORMS EACH DAY, HOWEVER THESE SHOWERS MANAGED TO MISS THE OFFICIAL  
OBSERVING SITE AT DENVER INTERNATIONAL AIRPORT.  
 
ANOTHER WEAK UPPER LEVEL STORM SYSTEM AND ASSOCIATED COLD FRONT  
BROUGHT COOLER UNSETTLED WEATHER TO THE AREA FROM THE 26TH THROUGH  
THE 29TH WITH SOME LIGHT SNOW ON THE 27TH  
 
THE MONTH ENDED ON A DRY AND WARMER NOTE AS WEAK UPPER LEVEL HIGH  
PRESSURE AND WESTERLY FLOW ALOFT SET UP OVER COLORADO.
