.....MARCH 2014 AVERAGE TEMPERATURE AND BELOW AVERAGE
PRECIPITATION.....

MARCH 2014 STARTED OUT COLD AND SNOWY WITH A STRONG PACIFIC CLOSED
LOW PRESSURE SYSTEM DOMINATING THE WESTERN HALF OF THE UNITED
STATES. THE SUBSEQUENT TROUGH BROUGHT AN INCH OF SNOW TO THE AIRPORT
AND TEMPERATURES WERE WELL BELOW AVERAGE FOR THE FIRST TWO DAYS OF
THE MONTH. ON THE THIRD THE ARCTIC AIR PUSHED OUT RAISING
TEMPERATURES TO ABOVE NORMAL OVER THE NEXT FEW DAYS, BUT WITH A WEAK
SHORT WAVE EMBEDDED IN THE UPPER LEVEL FLOW THE AIRPORT WAS ABLE TO
RECEIVE OVER TWO INCHES OF SNOW. ON THE SEVENTH A COMPLEX WEATHER
SYSTEM MOVED INTO THE REGION WITH A STRONG SURFACE LOW OVER
SOUTHEAST COLORADO AS WELL AS HIGH PRESSURE SOUTHWARD NEAR MONTANA.
THERE WAS A RAIN AND SNOW MIXTURE OVER THE PLAINS WITH A TIGHT SNOW
LINE THAT BROUGHT OVER AN INCH TO THE AIRPORT WITH A HIGH SNOW TO
WATER RATIO.

WARM ADVECTION AND DOWNSLOPING WINDS DUE TO AN UPPER RIDGE OVER THE
STATE BROUGHT SPRING-LIKE CONDITIONS AND ABOVE AVERAGE TEMPERATURES
FOR THE NEXT FEW DAYS. THE NEXT SYSTEM MOVED IN ON THE TENTH
BRINGING A COLD FRONT WITH INCREASED COLD AIR ADVECTION THAT BROUGHT
TEMPERATURES DOWN TO NORMAL FOR THE DAY AND A TRACE OF SNOW TO THE
AIRPORT. THE TEMPERATURE ROLLER COASTER CONTINUED WITH RIDGING
MOVING IN ON THE 12TH WITH ABOVE NORMAL TEMPERATURES FOR THE NEXT
FEW DAYS. CONDITIONS REMAINED DRY OVER THE NEXT 6 DAYS WITH
TEMPERATURES FLUCTUATING AROUND NORMAL. ON THE 18TH A FAST MOVING
UPPER LEVEL LOW MOVED IN BRINGING TEMPERATURES DOWN AND JUST A TRACE
OF SNOW TO THE AIRPORT.

THE NEXT SIGNIFICANT SYSTEM MOVED IN OVER THE 22ND WITH MODERATE
WESTERLY FLOW ALOFT AND AN UPPER LEVEL TROUGH OVER COLORADO. A HALF
AN INCH OF SNOW FELL AT THE AIRPORT WITH TEMPERATURES DIPPING TO
JUST BELOW FREEZING OVER THE DENVER METRO AREA. OVER THE NEXT FEW
DAYS A SERIES OF WEAK TROUGH CLIPPED AREAS OF NORTHERN COLORADO
BRINGING LIGHT RAIN AND SNOW TO THE PLAINS AND SNOW TO THE MOUNTAINS
WITH AVERAGE TO SLIGHTLY ABOVE AVERAGE TEMPERATURES. TOWARD THE END
OF THE MONTH AN UPPER LEVEL TROUGH MOVED OVER COLORADO BRINGING A
RAIN AND SNOW MIXTURE TO THE PLAINS AND AN ADDITIONAL FEW INCHES TO
THE MOUNTAINS WITH AVERAGE TEMPERATURES. WITH SPRING MOVING INTO THE
REGION THERE WAS AN INCREASED SNOW WATER EQUIVALENT RATIO AND SOME
REPORTS OF SMALL HAIL WITH THESE STORMS. THE MONTH ENDED WITH
TEMPERATURES WELL ABOVE NORMAL IN THE UPPER 60S TO LOWER 70S FOR THE
DENVER AREA.
