Dog Days of Summer ?

WHERE DID THE DOG DAYS OF SUMMER GO? YES IT IS STILL MID AUGUST BUT FEELING MORE LIKE MID OCTOBER. WHAT HAPPENED? TO BE BRIEF...A HIGHLY AMPLIFIED LARGE UPPER TROUGH WAS CARVED OUT...WITH SOME ASSISTANCE FROM HURRICANE CHARLEY...WHICH BROUGHT A COOL DRY CANADIAN AIRMASS INTO THE REGION. ONCE THE VERY UNSEASONABLE AIRMASS WAS IN PLACE WE PROCEEDED TO SET NUMEROUS RECORD LOWS...ALL TIME RECORD LOWS AND RECORD LOW MAXIMUM TEMPERATURES FOR JUST ABOUT ALL STATIONS FOR SEVERAL DAYS! HERE AT JACKSON WE SET DAILY RECORD LOWS FOR THE LAST 4 DAYS! IF THAT WAS NOT ENOUGH SATURDAY AND SUNDAY BOTH TIED THE ALL-TIME AUGUST RECORD LOW WITH 54 DEGREES. FOR 6 STRAIGHT DAYS...MEI HAS SMASHED ITS RECORD LOWS AND BROKE THE ALL-TIME AUGUST RECORD 3 TIMES WITH THE LOWEST READING COMING ON SUNDAY MORNING WITH 51 DEGREES! IN ADDITION TO BREAKING NUMEROUS RECORD LOWS ACROSS THE REGION...SEVERAL RECORD LOW MAXIMUMS WERE BROKEN...EVEN AS FULL SUNSHINE PREVAILED.

NOW FOR A HISTORICAL PERSPECTIVE. THIS AUGUST COOL EVENT IS LIKELY A
ONCE IN A LIFETIME EVENT. ALL LOCATIONS ACROSS THE FORECAST AREA
EITHER SET DAILY RECORD LOWS OR SET ALL-TIME AUGUST RECORD LOWS.
THIS DID NOT OCCUR JUST ONCE, BUT ON SEVERAL OR CONSECUTIVE
OCCASIONS. GLH, GWO, MEI AND HBG ALL HAD 6 CONSECUTIVE DAYS BELOW 60
DEGREES. JAN, TVR AND HEZ ALL HAD 5 CONSECUTIVE DAYS. A COOL STREAK
LIKE THIS HAS NEVER OCCURRED BEFORE IN AUGUST!
