RECORD.

THROUGHOUT MOST OF THE YEAR...TEMPERATURES WERE WELL ABOVE MONTHLY AVERAGES.
THE GREATEST DIFFERENCE BETWEEN THE MONTHLY AVERAGE TEMPERATURE AND THE
30-YEAR AVERAGE MONTHLY TEMPERATURE WAS IN MARCH...WITH A DEPARTURE FROM
NORMAL OF OVER 11 DEGREES. COOLER THAN AVERAGE TEMPERATURES WERE NOTED BY
OCTOBER AND NOVEMBER...BUT WARMER THAN AVERAGE READINGS RETURNED DURING
DECEMBER.

2012 WAS THE DRIEST YEAR SINCE 2010...BUT NOT IN THE TOP TEN DRIEST YEARS
ON RECORD. RAINFALL WAS ABOVE AVERAGE AND EVEN EXCESSIVE IN MARCH. HOWEVER...
BY MAY...DROUGHT DEVELOPED IN MUCH OF THE STATE...AND NORTH LITTLE ROCK WAS
NOT EXEMPT. EXCESSIVELY DRY WEATHER CONTINUED INTO AUGUST...WHEN THE REMNANTS
OF HURRICANE ISAAC PRODUCED HEAVY RAINFALL. BY OCTOBER...HOWEVER...RAINFALL
DECREASED AGAIN...WITH OCTOBER AND NOVEMBER BELOW AVERAGE. FREQUENT RAINS
RETURNED IN MID TO LATE DECEMBER.

MONTHS...WITH MEASURABLE SNOWFALL IN TWO MONTHS.
