  ...APRIL WAS WARMER AND WETTER THAN NORMAL IN OMAHA...

APRIL WAS MARKED BY PERIODIC SHOWERS AND THUNDERSTORMS...AND AS IS
TYPICAL OF SPRING...TEMPERATURE SWINGS BETWEEN MILD AND CHILLY
READINGS.  OVERALL...APRIL WAS THE 36TH WARMEST AND 37TH WETTEST FOR
OMAHA.

THE WARMEST AND WETTEST DAY OF THE MONTH CAME RIGHT OFF THE BAT...ON
THE 1ST...WITH A HIGH TEMPERATURE OF 85 DEGREES AND A DAILY RECORD
0.78 INCHES OF RAIN ACCOMPANIED BY THUNDER.  ADDITIONAL RAIN ON THE
2ND BROUGHT THE TOTAL OVER AN INCH...BEFORE A RELATIVE DRY SPELL
FROM THE 3RD THROUGH THE 7TH.  6 OF THE FIRST 7 DAYS OF THE MONTH
WERE WARMER THAN AVERAGE...BEFORE A COLD FRONT BROUGHT COOLER
TEMPERATURES ON THE 8TH AND 9TH...WITH HIGH TEMPERATURES STUCK IN
THE 40S ALONG WITH ADDITIONAL LIGHT SHOWERS AND THUNDERSTORMS.

TEMPERATURES REBOUNDED TO ABOVE NORMAL AGAIN FROM THE 10TH THROUGH
THE 18TH....WITH A COUPLE OF LIGHTER RAINS INTERSPERSED WITH
TEMPERATURES IN THE 60S AND 70S.  THUNDERSTORMS ON THE 12TH BROUGHT
SMALL TO MARGINALLY SEVERE HAIL TO THE OMAHA METRO AREA.  AGAIN...A
COLD FRONT BROUGHT HEAVIER RAIN...WITH 1.43 INCHES COMBINED ON THE
18TH AND 19TH.  THE AIR BEHIND THE FRONT WAS QUITE A BIT
COOLER...BRINGING THE COLDEST LOW TEMPERATURES OF THE MONTH AS
TEMPERATURES FELL JUST BELOW FREEZING ON THE 22ND AND 23RD.  THESE
WERE THE FIRST FREEZING TEMPERATURES SINCE MARCH 28. SHOULD THE
FREEZE ON THE 23RD BE THE LAST OF THE SEASON...IT WILL COME 5 DAYS
LATER THAN THE PERIOD-OF-RECORD AVERAGE OF APRIL 18.  THE LAST HARD
FREEZE OF 28 DEGREES OR COLDER IN OMAHA WAS ON MARCH 27...WHICH IS
10 DAYS EARLIER THAN THE PERIOD-OF-RECORD AVERAGE OF APRIL 6 AND IS
THE 21ST EARLIEST FINAL HARD FREEZE.

WARMER TEMPERATURES RETURNED FOR THE END OF THE MONTH...THOUGH THE
AVERAGE DAILY TEMPERATURES WERE NEAR NORMAL AS HIGHS IN THE 70S WERE
BALANCED BY LOWS IN THE 30S AND LOWER 40S.


DAILY RECORDS SET IN APRIL 2015:
DATE         RECORD           READING  PREVIOUS RECORD
