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.
