...A MOSTLY WARM AND DRY SEPTEMBER CONTRASTED WITH A FEW COOL AND
RAINY PERIODS...

THE SUMMER PATTERN CONTINUED ITS TRANSITION TO AUTUMN ACROSS
SOUTHEAST TEXAS DURING THE MONTH OF SEPTEMBER. THE SUBTROPICAL RIDGE
THAT HAD RETREATED OUT OF THE STATE BACK IN AUGUST MADE A COUPLE OF
RETURN VISITS AND BROUGHT TWO HOT AND DRY PERIODS. HOWEVER...A
SERIES OF COLD AND WARM FRONTS PLUS A COUPLE OF STORM SYSTEMS DID
PROVIDE SOME RAINFALL. SEPTEMBER BEGAN VERY HOT AND MOSTLY DRY EVEN
WITH ISOLATED SHOWERS MOVING OVER THE AREA DUE TO ONSHORE FLOW OFF
THE GULF OF MEXICO. THE HEAT COMPOUNDED THE OVERALL DRY CONDITIONS
AND DAYTIME HIGH TEMPERATURES EVEN REACHED TO AROUND 100 AT COLLEGE
STATION. LIMITED RAINFALL ARRIVED WITH A COLD FRONT THAT MOVED OFF
THE COAST ON THE 8TH...A WARM FRONT ON THE 12TH...A COLD FRONT ON
THE 13TH AND 14TH...AND AN OFFSHORE STORM SYSTEM THAT MOVED UP THE
COAST ON THE 16TH AND 17TH. HIGH PRESSURE THEN RETURNED A PERIOD OF
WARM AND DRY WEATHER FOR MUCH OF THE NEXT TWO WEEKS. AT THE END OF
THE MONTH A STORM SYSTEM MOVING ACROSS THE STATE TAPPED INTO
TROPICAL MOISTURE FROM THE REMNANTS OF HURRICANE MIRIAM NEAR BAJA
CALIFORNIA. THIS RESULTED IN COOLER WEATHER AND MUCH NEEDED
WIDESPREAD RAINFALL FROM THE 28TH TO THE 30TH.

CONCERNING DETAILS...SEPTEMBER 2012 WAS COOLER THAN LAST YEAR FOR
ALL THE MAJOR CLIMATE SITES. GALVESTON AND COLLEGE STATION WERE
ABOVE NORMAL FOR THE MONTH WHILE THE CITY OF HOUSTON AND HOBBY WERE
BOTH BELOW NORMAL. THANKS TO A COOLER MONTH COMPARED TO LAST YEAR...
2012 IS NOW THE SECOND WARMEST YEAR ON RECORD FOR COLLEGE STATION
AND HOUSTON HOBBY...WHILE 2012 IS TIED WITH 2011 FOR THE WARMEST
YEAR ON RECORD FOR THE CITY OF HOUSTON. 2012 IS STILL THE WARMEST
YEAR ON RECORD FOR THE CITY OF GALVESTON.
