PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LITTLE ROCK AR
127 PM CDT WED SEP 01 2010

...SUMMER 2010...THE HOTTEST ON RECORD AT LITTLE ROCK...

IT HAS BEEN VERY HOT THIS SUMMER. IN ALL...THERE WERE 21 DAYS WITH
HIGH TEMPERATURES AT OR ABOVE 100 DEGREES AT LITTLE ROCK. AT ONE
TIME...THE CENTURY MARK WAS REACHED ON EIGHT CONSECUTIVE DAYS. THERE
HAVE ALSO BEEN 60 CONSECUTIVE 90 DEGREE DAYS.

WHILE THIS SOUNDS IMPRESSIVE...IT DOES NOT EXACTLY COMPARE TO WHAT
HAPPENED IN 1954 AND 1980.

IN 1954...THERE WERE FORTY THREE 100 DEGREE DAYS FROM JUNE THROUGH
AUGUST...OR CLIMATOLOGICAL SUMMER. THERE WERE 42 SUCH DAYS IN 1980.
THE MERCURY HIT 100 DEGREES ON TEN OR MORE CONSECUTIVE DAYS TWICE IN
1980...AND ONCE IN 1954.

THIS SUMMER...THERE WERE 87 DAYS WITH A HIGH TEMPERATURE AT OR ABOVE
90 DEGREES...WHICH IS THE HIGHEST AMOUNT EVER RECORDED IN ONE
SUMMER.

FROM JUNE 30TH THROUGH AUGUST 28TH...THERE WERE 60 CONSECUTIVE DAYS
WITH A HIGH TEMPERATURE OF 90 DEGREES OR GREATER...WHICH WAS THE
MOST SINCE 1954...AND THE GREATEST NUMBER OF CONSECUTIVE 90 DEGREE
DAYS ON RECORD.

HOWEVER...IT SHOULD BE NOTED THAT THIS RECORD WOULD NOT EVEN BE
CONSIDERED IF NOT FOR JULY 19TH 1954. A HIGH TEMPERATURE OF 82
DEGREES THAT DAY ENDED 42 CONSECUTIVE 90-DEGREE DAYS AT LITTLE ROCK.
THE NEXT DAY BEGAN A 53-DAY STREAK OF CONSECUTIVE 90-DEGREE DAYS. SO
IF NOT FOR THAT ONE PARTICULAR DAY...LITTLE ROCK COULD HAVE HAD A
96-DAY STREAK OF CONSECUTIVE 90-DEGREE DAYS.

HERE ARE SOME RECORDS WORTH MENTIONING...

GIVEN THE RECORDS ORIGINALLY SET IN THESE TWO YEARS...IT WOULD MAKE
SENSE THAT THE WARMEST AVERAGE SUMMER TEMPERATURES HAD BEEN IN 1954
AND 1980.

THE RECORDS ARE AS FOLLOWS...

___________________________________________________________________

WARMEST AVERAGE SUMMER TEMPERATURES
___________________________________________________________________

 1. 2010......85.8 DEGREES
 2. 1954......85.4 DEGREES
 3. 1980......84.8 DEGREES
 4. 1998......84.7 DEGREES
 5. 1943......83.8 DEGREES

THIS SUMMER HAS TOPPED THE WARMEST AVERAGE TEMPERATURE LIST...AND
HAPPENS TO BE WARMER THAN 1954 AND 1980.

THIS YEAR HAS MADE THE RECORD BOOKS BECAUSE IT HAS BEEN CONSISTENTLY
WARM. IN JUNE OF 1954...THERE WERE TWO DAYS WITH HIGH TEMPERATURES
IN THE 70S...AND TWO NIGHTS WITH LOWS IN THE 50S.

IRONICALLY...THE SAME THING HAPPENED IN JUNE OF 1980...EXCEPT LOWS
IN THE 50S OCCURRED ON THREE NIGHTS.

IN JUNE OF THIS YEAR...THE  COOLEST LOWS WERE IN THE UPPER 60S AND
THE COOLEST HIGHS WERE IN THE UPPER 80S.

THIS YEAR...THERE HAVE BEEN 7 DAYS WITH LOW TEMPERATURES AT OR ABOVE
80 DEGREES...WHICH IS ALMOST A RECORD.
___________________________________________________________________

LOWS AT OR ABOVE 80 DEGREES
___________________________________________________________________

YEARS WITH NUMBER OF DAYS WITH LOW TEMPERATURES AT OR ABOVE 80
DEGREES

 1. 1998 - 8
*2. 2010 - 7
 3. 1930 - 7
 4. 1881 - 7
 5. 1932 - 5

 7. 1980 - 3
 8. 1934 - 3
 9. 1997 - 2
10. 1977 - 2

THIS SUMMER...THE TEMPERATURE ONLY FELL BELOW 70 DEGREES ON FIVE
DAYS...JUNE 7TH...AUGUST 24TH...26TH...27TH...AND 28TH. FROM JUNE
8TH THROUGH AUGUST 23RD...THE TEMPERATURE WAS CONTINUOUSLY ABOVE 70
DEGREES. THIS 77 DAY PERIOD WAS THE GREATEST NUMBER OF CONSECUTIVE
DAYS WITH TEMPERATURES AT OR ABOVE 70 DEGREES ON RECORD.

A BREAKDOWN OF EACH MONTH BY THE NUMBERS...
__________________________________________________________________

TEMPERATURES IN JUNE
___________________________________________________________________

2010.....AVERAGE HIGH.....94.7.....AVERAGE LOW.....75.2
1980.....AVERAGE HIGH.....89.8.....AVERAGE LOW.....68.9
1954.....AVERAGE HIGH.....93.8.....AVERAGE LOW.....70.8

THE HEAT REALLY CRANKED UP IN JULY OF 1954 AND 1980...AND DAYTIME
TEMPERATURES WERE HOTTER THAN THIS YEAR. HOWEVER...IT COOLED A BIT
MORE AT NIGHT.

BY THE NUMBERS...

__________________________________________________________________

TEMPERATURES IN JULY
___________________________________________________________________

2010.....AVERAGE HIGH.....96.0.....AVERAGE LOW.....76.0
1980.....AVERAGE HIGH....101.6.....AVERAGE LOW.....74.6
1954.....AVERAGE HIGH.....98.8.....AVERAGE LOW.....74.6

IT STAYED HOT IN AUGUST OF 1954 AND 1980...AND THAT HAS BEEN THE
CASE THIS YEAR. AGAIN...THERE WAS MORE COOLING AT NIGHT IN THE
PAST.

BY THE NUMBERS...

__________________________________________________________________

TEMPERATURES IN AUGUST
___________________________________________________________________

2010.....AVERAGE HIGH.....97.5.....AVERAGE LOW.....75.5
1980.....AVERAGE HIGH....100.4.....AVERAGE LOW.....73.5
1954.....AVERAGE HIGH....100.2.....AVERAGE LOW.....74.2


__________________________________________________________________

FOR THE ENTIRE SUMMER
__________________________________________________________________

2010.....AVERAGE HIGH.....96.1.....AVERAGE LOW.....75.6
1980.....AVERAGE HIGH.....97.4.....AVERAGE LOW.....72.4
1954.....AVERAGE HIGH.....97.7.....AVERAGE LOW.....73.2

SO...BY THE NUMBERS...THE SUMMERS OF 1954 AND 1980 WERE HOTTER IN
TERMS OF HIGH TEMPERATURES. HOWEVER...THE VERY WARM LOW TEMPERATURES
HAVE PUSHED THE SUMMER TO THE TOP OF THE RECORDS IN TERMS OF AVERAGE
TEMPERATURE.

MANY DAILY TEMPERATURE RECORDS HAVE BEEN SET AT LITTLE ROCK THIS
SUMMER. SOME OF THESE TEMPERATURES HAVE BEEN AMONG THE WARMEST ON
RECORD.

* - WARMEST DAILY LOW TEMPERATURES SINCE JULY 18TH 2000

LOW TEMPERATURES MAY HAVE BEEN WARMER THIS YEAR BECAUSE OF ELEVATED
MOISTURE LEVELS. MOISTURE KEEPS READINGS UP AT NIGHT...WITH A DRIER
AIRMASS ALLOWING READINGS TO FALL MORE READILY. THERE WERE SEVERAL
ROUNDS OF MOISTURE PROVIDED BY THE REMNANTS OF TROPICAL SYSTEMS.
ALSO...IT WAS A RECORD WET YEAR IN 2009...AND SOIL MOISTURE
CONTRIBUTED WATER TO THE ATMOSPHERE THROUGH EVAPORATION.

SO...WHILE THE SUMMERS OF 1954 AND 1980 MAY BE THE MOST MEMORABLE IN
TERMS OF HOT WEATHER...2010 HAS CERTAINLY EARNED ITS PLACE IN THE
CONVERSATION.
