..APRIL WAS WARMER AND SLIGHLY DRIER THAN NORMAL IN OMAHA
 
 
THE AVERAGE TEMPERATURE OF 54.4 DEGREES WAS THE 34TH WARMEST APRIL  
ON RECORD, WHILE THE TOTAL PRECIPITATION OF 2.42 INCHES HOVERED JUST  
BELOW NORMAL. NO SNOW FELL IN APRIL, THOUGH A TRACE OF  
SNOW/SLEET/HAIL WAS RECORDED DUE TO HAIL.  
 
THE LONG STRETCH OF OVERCAST CONDITIONS THAT CLOSED THE MONTH OF  
MARCH ALSO LINGERED THROUGH THE FIRST FIVE DAYS OF APRIL, WITH  
LITTLE DIFFERENCE BETWEEN DAY AND NIGHT TEMPERATURES AND WITH A  
TRACE OR MORE OF RAIN ON THE 1ST THROUGH THE 4TH. SUN BROKE THROUGH  
ON THE 6TH, THOUGH DAYS REMAINED MORE CLOUDY THAN SUNNY ALMOST  
THROUGHOUT THE ENTIRE MONTH OF APRIL. TEMPERATURES DID REMAIN NEAR  
TO ABOVE AVERAGE FROM THE 1ST THROUGH THE 9TH, WITH TEMPERATURES  
PEAKING AT 82 DEGREES ON THE 9TH, THE WARMEST READING OF THE MONTH.  
A COLD FRONTAL PASSAGE BROUGHT SHOWERS AND THUNDERSTORMS ON THE 9TH,  
AS WELL AS MUCH COOLER TEMPERATURES FOR THE 10TH AND 11TH. THE  
COLDEST TEMPERATURE OF THE MONTH, AT 30 DEGREES, OCCURRED ON THE  
11TH AND CURRENTLY STANDS AS THE LAST FREEZE THIS SPRING.  
 
TEMPERATURES POPPED RIGHT BACK ABOVE NORMAL FOR THE 12TH TO 19TH,  
WITH INCREASING HUMIDITY AND SEVERAL DAYS OF THUNDERSTORMS AROUND  
OMAHA. STORMS IN THE NORTHERN METRO AREA ON THE MORNING OF THE 19TH  
WERE ON THE STRONG SIDE, BUT OTHERWISE, OMAHA REMAINED OUTSIDE OF  
AREAS AFFECTED BY SEVERE WEATHER DURING THAT PERIOD. OMAHA ALSO  
MISSED SOME OF THE HIGHER DAILY RAINFALL TOTALS MID-MONTH, WITH NO  
DAY'S PRECIPITATION EXCEEDING 0.33 INCHES.  
 
THE COLD FRONT THAT USHERED IN STORMS ON THE 19TH ALSO USHERED IN A  
DROP TO COOLER TEMPERATURES THAT WAS REINFORCED A COUPLE OF TIMES  
THROUGH THE REST OF THE MONTH. FROM THE 20TH THROUGH THE 30TH,  
TEMPERATURES ONLY ROSE ABOVE NORMAL ON TWO DAYS, THE 23RD AND 24TH.  
THE END OF THE MONTH WAS PARTICULARLY CHILLY, WITH HIGH TEMPERATURES  
IN THE 40S ON FOUR OF FIVE DAYS FROM THE 26TH TO THE 30TH AND WITH  
LOWS IN THE UPPER 30S TO LOWER 40S. IT ALSO WAS A WETTER PERIOD,  
WITH 1.43 INCHES OF RAIN ON THE 28TH TO 30TH. A FEW RUMBLES OF  
THUNDER AND EVEN SOME VERY SMALL HAIL (PEA SIZE OR LESS) WERE  
RECORDED ON THE 30TH, PROVIDING THE ONLY TRACE OF FROZEN  
PRECIPITATION FOR THE MONTH.  
 
THE LAST FREEZE (SO FAR) OCCURRED ON APRIL 11 AT 30 DEGREES. THIS IS  
7 DAYS EARLIER THAN THE PERIOD-OF-RECORD AVERAGE OF APRIL 18. THE  
LAST HARD FREEZE (SO FAR) OCCURRED BACK ON MARCH 18, WHICH IS A FULL  
19 DAYS EARLIER THAN THE PERIOD-OF-RECORD AVERAGE OF APRIL 6. WITH  
NO FREEZES IN THE FORECAST INTO EARLY MAY, IT IS LIKELY THAT THESE  
WILL STAND AS THE FINAL FREEZE DATES.
