| gotta love that last paragraph... PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 858 AM CDT THU JUN 25 2009 ...YES...IT`S BEEN HOT... ...YES...IT`S BEEN DRY... UPDATED - THE OVERNIGHT LOW (JUNE 25) AT INTERCONTINENTAL AIRPORT WAS ONLY 84 DEGREES. IF THE TEMPERATURE DOES NOT FALL BELOW 84 DEGREES BY MIDNIGHT...THIS WILL BE THE WARMEST OVERNIGHT LOW TEMPERATURE EVER RECORDED IN THE MONTH OF JUNE AND WILL ALSO TIE FOR THE WARMEST OVERNIGHT LOW TEMPERATURE EVER RECORDED FOR THE CITY OF HOUSTON. THE ONLY OTHER TIME THE TEMPERATURE FELL TO 84 DEGREES WAS ON JULY 29TH 1895. THERE IS NO WAY TO SUGARCOAT THE CURRENT WEATHER REGIME. IT HAS BEEN HOT AND IT HAS BEEN VERY DRY. LET`S START WITH THE TEMPERATURES. THE MONTH IS NOT OVER YET...SO MUCH CAN CHANGE. AT THE CURRENT TIME...HOUSTON IS SUFFERING THROUGH IT`S 5TH WARMEST JUNE. AT HOBBY AIRPORT...THIS IS THE 5TH WARMEST JUNE. GALVESTON IS ENDURING IT`S 10TH WARMEST JUNE AND COLLEGE STATION IS ENDURING IT`S 5TH WARMEST JUNE. TO PUT THIS IN PERSPECTIVE...THE FIRST SEVEN DAYS OF JUNE WERE COOLER THAN NORMAL SO THE INTENSE HEAT OVER THE LAST 17 DAYS HAS MADE UP THE TEMPERATURE DEFICIT WITH CHANGE TO SPARE. THIS LATEST HEATWAVE SHOWS NO SIGN OF RELENTING SO THE MONTHLY AVERAGE TEMPERATURE WILL LIKELY INCREASE. 2009 AVG TEMP WARMEST AVG TEMP (ENTIRE MONTH) IAH 84.5 5TH WARMEST 85.5 IN 1998 HOU 83.8 5TH WARMEST 86.2 IN 1998 GLS 83.7 10TH WARMEST 85.6 IN 1881 CLL 84.9 5TH WARMEST 86.7 IN 1998 THE TEMPERATURE CLIMBED TO 104 DEGREES AT INTERCONTINENTAL AIRPORT ON JUNE 24TH.

BUT IT HAS ALSO BEEN DRY! HOW DRY? CURRENTLY...HOUSTON INTERCONTINENTAL AIRPORT HAS GONE 31 CONSECUTIVE DAYS WITHOUT MEASURABLE RAIN. THE DRIEST STRETCH OF WEATHER EVER RECORDED FOR HOUSTON WAS BACK IN 1904. THERE WAS NO MEASURABLE RAIN BETWEEN JANUARY 8 1904 AND FEBRUARY 16 1904 - 40 DAYS! BELOW IS A TABLE WITH THE DRIEST PERIODS ON RECORD DATE NUMBER OF DRY DAYS 01/08/1904 - 02/17/1904 40 09/11/1917 - 10/17/1917 37 09/20/1963 - 10/25/1963 36 05/01/1937 - 06/03/1937 34 09/22/1978 - 10/24/1978 33 04/25/2009 - 06/24/2009 31* * THIS TIES FOR THE 12TH LONGEST PERIOD WITHOUT MEASURABLE RAIN. THE LAST TIME HOUSTON WENT 31 DAYS WITHOUT RAIN WAS FROM JULY 31 1990 THROUGH AUGUST 30 1990. OTHER COMMUNITIES ACROSS SOUTHEAST TEXAS HAVE SUFFERED A SIMILAR FATE. COLLEGE STATION...HUNTSVILLE AND CONROE HAVE NOT RECORDED MEASURABLE RAINFALL DURING JUNE. ANGLETON...BAY CITY AND EDNA HAVE YET TO RECEIVE 10 INCHES OF RAIN THIS YEAR. EXTREME TO EXCEPTIONAL DROUGHT CONDITIONS ARE AFFECTING PARTS OF JACKSON...MATAGORDA... AND BRAZORIA COUNTIES. MAY AND JUNE ARE TYPICALLY TWO OF THE WETTEST MONTHS OF THE YEAR SO THIS BUILDING DROUGHT IS OF GREAT CONCERN. 2009 RAINFALL ANNUAL DEPARTURE MAY/JUNE 2009 IAH 16.85 -6.36 0.38 HOU 21.27 -3.35 1.59 GLS 10.86 -8.13 0.51 CLL 13.97 -6.04 1.41 HOUSTON HAS RECEIVED 16.85 INCHES OF RAIN IN 2009. THE NORMAL VALUE THROUGH JUNE 23 IS 23.21 INCHES. THIS IS 6.36 INCHES BELOW NORMAL AND THIS DEFICIT IS LIKELY TO GROW. IF NOT FOR THE FREAKISH HEAVY RAIN AT THE END OF APRIL...THE HOUSTON AREA WOULD BE 10 TO 12 INCHES OF RAIN BELOW NORMAL. SINCE MAY 1...HOUSTON HAS ONLY RECEIVED 0.38 INCHES OF RAIN. THIS IS THE SECOND DRIEST MAY 1 THROUGH JUNE 24 ON RECORD. BELOW IS A TABLE WITH THE FIVE DRIEST MAY 1 THROUGH JUNE 24 ON RECORD: RAINFALL DATE 0.35 1906 0.38 2009 0.45 1931 1.15 1901 1.72 1915 IF ACCUMULATING RAIN DOES NOT FALL AT INTERCONTINENTAL AIRPORT THROUGH JUNE 26TH...IT WILL BE THE DRIEST PERIOD IN HISTORY. IF ADDITIONAL RAIN DOES NOT FALL BY THE END OF THE MONTH...THIS WILL BE THE DRIEST MAY/JUNE RAINFALL TOTAL IN RECORDED HISTORY. HERE ARE THE FIVE DRIEST MAY/JUNE IN RECORDED HISTORY: MAY/JUNE RAIN * 0.38 IN 2009 (THROUGH JUNE 23) 0.98 IN 1931 1.78 IN 1915 1.82 IN 1934 1.87 IN 1901 1.96 IN 1906 SO IS THERE ANY HOPE FOR RAIN? HOW DOES A VAGUE "MAYBE" SOUND? A FEW SHOWERS DEVELOPED OVER SOUTHEAST TEXAS LAST NIGHT AND FEW MORE ARE POSSIBLE TONIGHT. THE EXPANSIVE RIDGE WHICH HAS TAKEN UP RESIDENCE OVER SOUTHEAST TEXAS IS ALSO FORECAST TO SHIFT NORTHWEST BY THE END OF THE MONTH. THIS SHOULD WEAKEN THE CAPPING INVERSION AND ALLOW DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS TO DEVELOP BY EARLY JULY. LONG RANGE MODELS HAVE TEASED US BEFORE ABOUT THE RIDGE WEAKENING AND MOVING WEST. BUT LIKE AN UNWELCOME HOUSE GUEST...THE RIDGE SHOWS NO SIGNS OF LEAVING. $$ |
