NWS Birmingham, AL wrote its last area forecast discussion before the first event at Jul 23, 5:21 PM CST, 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 621 PM CDT FRI JUL 23 2010 .UPDATE...FOR 00Z AVIATION. && .DISCUSSION... WE ARE IN THE MIDDLE OF THE HOTTEST DAY OF THE YEAR OVERALL FOR CENTRAL ALABAMA...WITH SEVERAL CITIES NOW REPORTING TEMPERATURES AT OR ABOVE 100 DEGREES. THERE ARE A FEW SHOWERS AROUND (PERHAPS A FEW RUMBLES OF THUNDER AS WELL)...BUT THE REMAINS THE EXCEPTION RATHER THAN THE RULE. WILL HAVE TO DEAL WITH SOME LEFTOVER WEATHER IN THE FIRST PERIOD TONIGHT...WITH SMALL POPS (20 PERCENT OR LESS) IN THE SOUTHERN AND EASTERN COUNTIES. WHAT CONVECTION WAS LEFT OF BONNIE LATE THIS AFTERNOON WAS FAIRLY DISORGANIZED LOOKING ON SATELLITE IMAGERY. THE SYSTEM AS A WHOLE DOES NOT COVER A LOT OF AREA...AND THE COMPUTER MODELS (AND OFFICIAL TRACK FORECAST) SUGGEST ITS AFFECTS ON CENTRAL ALABAMA WILL BE PERIPHERAL AT MOST. SO...WE ARE LEFT WITH ANOTHER HOT DAY ON SATURDAY...AND THEN NOT QUITE AS HOT ON SUNDAY. THE INDIRECT IMPACT OF BONNIE MAY BE TO BRING DEEPER MOISTURE (HIGHER DEWPOINTS) INTO OUR AREA BY SUNDAY. SO EVEN THOUGH TEMPS MAY BE SEVERAL DEGREES LOWER...HEAT INDEX VALUES MAY NOT BE MUCH LOWER AT ALL DUE TO THE INCREASED HUMIDITY. LONG RANGE MODELS IN GENERAL AGREEMENT THAT THE UPPER RIDGE WILL BECOME RE-ESTABLISHED OVER ALABAMA BY THE MIDDLE OF NEXT WEEK. THUS...ABOVE TO MUCH ABOVE NORMAL TEMPERATURES WILL LIKELY CONTINUE. THERE IS SOME INDICATION THAT A LONGWAVE TROUGH MAY ACTUALLY START TO DIG INTO THE EASTERN STATES NEXT WEEKEND. WE SHALL SEE. /61/ && .AVIATION...00Z TAF DISCUSSION. AT ISSUANCE...NORTHERN SITES REMAIN FAIRLY QUIET. CU FIELDS ARE DIMINISHING AND A FEW HIGH CLOUDS REMAIN. THIS WILL BE THE CASE THROUGH THE MIDNIGHT HOUR WHEN TCL/EET/ANB WILL LIKELY BEGIN TO SEE SOME MVFR FOG SETTLE IN. TCL COULD SEE MORE HIGH CLOUDS THAN OTHER SITES AS THE BLOW OFF FROM TROPICAL STORM BONNIE WILL LIKELY ONLY AFFECT SOUTHWESTERN PORTIONS OF OUR AREA. FOR THE SOUTHERN SITES OF MGM AND TOI...A LITTLE MORE ACTIVITY AT ISSUANCE. SHOWERS AND THUNDERSTORMS THAT WERE SCATTERED AT BEST HAVE BECOME A LITTLE MORE ORGANIZED AND ARE AFFECTING BOTH SITES. TOI SHOULD BE DONE BY 00Z...BUT MGM COULD STILL SEE SOME TSRA THROUGH 01Z WITH A WIND GUST TO 30KTS. THERE WILL STILL BE AN OUTSIDE CHANCE OF SOME ISOLATED SHOWERS OVERNIGHT AT BOTH SOUTHERN SITES BUT WITH THIS BEING SUCH A SMALL CHANCE...WILL LEAVE OUT OF PREVAILING. MVFR FOG LIKELY AT BOTH MGM AND TOI AFTER MIDNIGHT AS WELL AS CURRENT RAINFALL WILL LIKELY INCREASE THE CHANCE OF THIS. NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO THE END OF THE FORECAST THROUGH THE END OF 2010. THE CEILOMETER DATA WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY. 27 && .BMX WATCHES/WARNINGS/ADVISORIES... HEAT ADVISORY UNTIL 7 PM CDT SATURDAY FOR ALL OF CENTRAL ALABAMA. &&

SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE BIRMINGHAM AL 1241 PM CDT FRI JUL 23 2010 ALZ011>015-017>050-241000- AUTAUGA-BARBOUR-BIBB-BLOUNT-BULLOCK-CALHOUN-CHAMBERS-CHEROKEE- CHILTON-CLAY-CLEBURNE-COOSA-DALLAS-ELMORE-ETOWAH-FAYETTE-GREENE-HALE- JEFFERSON-LAMAR-LEE-LOWNDES-MACON-MARENGO-MARION-MONTGOMERY-PERRY- PICKENS-PIKE-RANDOLPH-RUSSELL-SHELBY-ST CLAIR-SUMTER-TALLADEGA- TALLAPOOSA-TUSCALOOSA-WALKER-WINSTON- 1241 PM CDT FRI JUL 23 2010 ...THE FOLLOWING MESSAGE IS TRANSMITTED AT THE REQUEST OF THE ALABAMA DEPARTMENT OF PUBLIC HEALTH.... THE ALABAMA DEPARTMENT OF PUBLIC HEALTH ADVISES THE PUBLIC TO BE ALERT TO THE WARNING SIGNALS OF HEAT ILLNESSES NOW THAT THE NATIONAL WEATHER SERVICE IN BIRMINGHAM HAS ISSUED A HEAT ADVISORY WHICH IS IN EFFECT THROUGH SATURDAY AFTERNOON FOR CENTRAL ALABAMA. THE COMBINATION OF HEAT AND HUMIDITY WILL CREATE HEAT INDEX VALUES NEAR OR ABOVE 105 DEGREES F BOTH THIS AFTERNOON AND FRIDAY AFTERNOON, ACCORDING TO THE NATIONAL WEATHER SERVICE. IN ADDITION, OVERNIGHT TEMPERATURES IN MANY AREAS WILL NOT DROP BELOW 75 DEGREES F SO THAT ANY HEAT THAT BUILDS UP IN INDOOR AREAS WILL HAVE VERY LITTLE OPPORTUNITY TO ESCAPE. PEOPLE SHOULD DRINK PLENTY OF WATER, STAY IN AN AIR-CONDITIONED ROOM, AND KEEP OUT OF THE SUN. THE PUBLIC SHOULD ALSO CHECK ON THE ELDERLY AND ENSURE PETS HAVE PLENTY OF WATER TO DRINK AND A SHADY PLACE TO COOL OFF. HEAT RELATED ILLNESSES OCCUR WHEN THE BODY'S TEMPERATURE CONTROL SYSTEM IS OVERLOADED. THE ALABAMA DEPARTMENT OF PUBLIC HEALTH CAUTIONS EVERYONE TO BE ALERT TO THE WARNINGS THAT MAY SIGNAL HELP IS NEEDED. HEAT STROKE, SOMETIMES CALLED SUNSTROKE, IS THE MOST SERIOUS HEAT RELATED ILLNESS. IT OCCURS WHEN THE BODY BECOMES UNABLE TO CONTROL ITS TEMPERATURE. THE BODY'S TEMPERATURE RISES RAPIDLY, THE SWEATING MECHANISM FAILS AND THE BODY IS UNABLE TO COOL DOWN. BODY TEMPERATURE MAY RISE TO 106 DEGREES F OR HIGHER WITHIN 10 TO 15 MINUTES. HEAT STROKE CAN CAUSE DEATH OR PERMANENT DISABILITY IF EMERGENCY TREATMENT IS NOT PROVIDED. WARNING SIGNS OF HEAT STROKE VARY, BUT INCLUDE THE FOLLOWING: -AN EXTREMELY HIGH BODY TEMPERATURE (ABOVE 103 DEGREES F) -RED, HOT AND DRY SKIN (NO SWEATING) -RAPID, STRONG PULSE -THROBBING HEADACHE -DIZZINESS -NAUSEA -CONFUSION -UNCONSCIOUSNESS GET THE PERSON TO A SHADY AREA, COOL RAPIDLY IN A TUB OF COOL WATER, PLACE IN A COOL SHOWER, SPRAY WITH COOL WATER FROM A GARDEN HOSE, SPLASH WITH COOL WATER, OR, IF THE HUMIDITY IS LOW, PLACE IN A COOL, WET SHEET AND FAN VIGOROUSLY. MONITOR BODY TEMPERATURE AND CONTINUE COOLING EFFORTS UNTIL THE PERSON'S BODY TEMPERATURE DROPS TO 101 TO 102 DEGREES F. IF EMERGENCY MEDICAL PERSONNEL ARE DELAYED, CALL A HOSPITAL EMERGENCY ROOM FOR FURTHER INSTRUCTIONS. DR. DONALD WILLIAMSON, STATE HEALTH OFFICER, SAID, "HEAT STROKE IS A LIFE-THREATENING EMERGENCY. A PERSON WITH HEAT STROKE IS LIKELY TO BE UNCONSCIOUS OR UNRESPONSIVE, SO HE OR SHE CANNOT SAFELY CONSUME ANY LIQUIDS. UNDER NO CIRCUMSTANCES SHOULD YOU GIVE ANY ALCOHOL TO A PERSON WITH HEAT STROKE OR ANY HEAT ILLNESS." FOLLOW THESE PREVENTIVE MEASURES TO AVOID HEAT ILLNESSES: -DRINK MORE FLUIDS, AND AVOID BEVERAGES CONTAINING ALCOHOL OR CAFFEINE -WHEN TEMPERATURES ARE EXTREME, STAY INDOORS, IDEALLY IN AN AIR- CONDITIONED PLACE -TAKE A COOL SHOWER OR BATH -REDUCE OR ELIMINATE STRENUOUS ACTIVITIES DURING THE HOTTEST TIME OF THE DAY -PROTECT YOURSELF FROM THE SUN WITH A WIDE BRIMMED HAT, LIGHT- COLORED AND LOOSE-FITTING CLOTHING -USE A SUNSCREEN OF SPF 15 OR HIGHER -NEVER LEAVE PETS OR PEOPLE IN A PARKED VEHICLE. INDIVIDUALS WITH HEART PROBLEMS, POOR CIRCULATION, DIABETES, A PREVIOUS STROKE OR OBESITY ARE AT GREATER RISK OF BECOMING SICK IN HOT WEATHER. THE RISK OF HEAT RELATED ILLNESS MAY INCREASE AMONG PEOPLE USING MEDICATIONS FOR HIGH BLOOD PRESSURE, NERVOUSNESS OR DEPRESSION. FOR MORE INFORMATION, VISIT WWW.ADPH.ORG. 75/LINHARES
