THE AVERAGE TEMPERATURE OF 65.9 DEGREES WAS THE 33RD WARMEST
SEPTEMBER ON RECORD IN NORFOLK, WITH FOUR DAYS REACHING 90 DEGREES

THE MONTH STARTED ON THE COOL SIDE, WITH BELOW-NORMAL TEMPERATURES
ON FOUR OF THE FIRST SEVEN DAYS OF THE MONTH. LOWS ON TWO OF THOSE
DAYS REACHED THE UPPER 40S, AND THE COOLEST LOW TEMPERATURE OF THE
MONTH WAS RECORDED ON THE 6TH, AT 43 DEGREES. A LIGHT 0.01 INCHES OF
RAIN WAS MEASURED ON THE 1ST. WARM TEMPERATURES EMERGED FROM THE 8TH
THROUGH THE 24TH, WITH JUST ONE DAY (THE 17TH) FALLING BELOW NORMAL.
TEMPERATURES REACHED THE 90S ON THE 13TH THROUGH THE 15TH. RAIN
RETURNED ON THE 15TH TO 16TH, WITH 0.18 INCHES OF RAIN MEASURED IN A
THUNDERSTORM. THE COOLER WEATHER THAT FOLLOWED THIS RAIN DIDN`T LAST
LONG, WITH TEMPERATURES REBOUNDING ON THE 18TH DESPITE 0.27 INCHES
OF RAIN IN THUNDERSTORMS AGAIN. PARTICULARLY WARM WEATHER ARRIVED
FROM THE 19TH THROUGH THE 24TH. TEMPERATURES REACHED 90 DEGREES OR
HIGHER ON FOUR OF THOSE SIX DAYS - THE 19TH AND THE 21ST THROUGH
23RD - AND THE HIGHEST TEMPERATURE OF THE MONTH WAS RECORDED ON THE
22ND, AT 97 DEGREES. ADDITIONALLY, THE WARM MINIMUM TEMPERATURE OF
75 DEGREES ON THE 22ND TIED A DAILY RECORD.

INCHES TOTAL ON THOSE TWO DAYS ALONE. WHILE TEMPERATURES STARTED
WARM ON THE 24TH, MUCH COOLER WEATHER ARRIVED ON THE 25TH, WITH
