 ...APRIL WAS WARMER AND DRIER THAN NORMAL IN LINCOLN...

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 37TH WARMEST AND 50TH DRIEST IN
LINCOLN.

THE WARMEST DAY OF THE MONTH CAME RIGHT OFF THE BAT...ON THE
1ST...WITH A HIGH TEMPERATURE OF 85 DEGREES AND JUST OVER HALF AN
INCH OF RAIN BETWEEN THE 1ST AND 2ND. 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 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. AGAIN...A COLD FRONT BROUGHT
HEAVIER RAIN...WITH 0.78 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 BELOW FREEZING ON
THE 22ND AND 23RD.  SHOULD THE FREEZE ON THE 23RD BE THE LAST OF THE
SEASON...IT WILL EXACTLY MATCH THE PERIOD-OF-RECORD AVERAGE.  THE
LAST HARD FREEZE OF 28 DEGREES OR COLDER OCCURRED ON THE
22ND...WHICH IS 11 DAYS LATER THAN THE PERIOD-OF-RECORD AVERAGE OF
APRIL 11...WITH THE COLDEST TEMPERATURE OF THE MONTH AT 26 DEGREES.

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:
