Area forecast discussion, Sep 7, 1:06 PM CDT, 2 hours 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 106 PM CDT FRI SEP 7 2012 .DISCUSSION... UPDATED FOR THE 18Z AVIATION DISCUSSION BELOW. && .AVIATION... A FRONTAL BOUNDARY WILL SWEEP THROUGH THE STATE TONIGHT. THIS IS EXPECTED TO GIVE AT LEAST TEMPO -TSRA CONDITIONS TO ALL SITES AT SOME POINT. HOWEVER...COMPLICATING MATTERS IS THAT SHOWERS/TSTMS WILL ALSO FIRE OUT AHEAD OF THE FRONT...MAINLY IN THE NORTH PART OF THE STATE THIS AFTERNOON. SINCE CONFIDENCE IN THE PLACEMENT AND COVERAGE OF PRE-FRONTAL CONVECTION IS LOWER...DECIDED TO HEDGE MENTION OF THUNDER IN TAFS TOWARDS THE FRONTAL BOUNDARY...AND AMEND IF/WHEN NECESSARY FOR THUNDERSTORMS AFFECTING TERMINALS BEFORE FROPA. THIS WILL AVOID HAVING EXTENDED TIME PERIODS OF VCTS OR TEMPO THUNDER IN THE TAFS. REGARDING FRONTAL PASSAGE...HAVE FRONTAL PASSAGE AROUND 00Z-03Z AT KHRO AND KBPK...03Z-06Z FOR KHOT...KLIT...AND KM89...AND FINALLY 06Z-09Z FOR KPBF AND KLLQ. INCLUDED TEMPO -TSRA AND AT LEAST MVFR CIGS/VSBY FOR ALL SITES...EXCEPT IFR UP NORTH...CENTERED ON EXPECTED FROPA. PRECIP COULD LINGER BEHIND THE FRONT A LITTLE...BUT IT WILL BE QUICK MOVING SO THIS TIMING LOOKS TO BE REASONABLE AT THIS POINT. BEHIND THE FRONT WILL BE GUSTY WINDS...WITH GUSTS INTO THE MID 20KT POSSIBLE AT OR JUST BEYOND THE END OF THE 18Z TAF PERIOD. && PREV DISCUSSION... /ISSUED 441 AM CDT FRI SEP 7 2012/ SHORT TERM...TODAY THROUGH MONDAY NIGHT ONE MORE HOT DAY...AND THEN TEMPERATURES WILL TUMBLE. READINGS TODAY WILL BE WELL ABOVE NORMAL...WITH SEVERAL PLACES TOPPING THE CENTURY MARK. HUMIDITY LEVELS WILL BE HIGH ENOUGH IN MUCH OF CENTRAL/SOUTHERN ARKANSAS TO RESULT IN HEAT INDEX VALUES BETWEEN 105 AND 110 DEGREES THIS AFTERNOON. KEPT A HEAT ADVISORY IN EFFECT CENTRAL/SOUTH THROUGH THIS EVENING. LATER THIS AFTERNOON/TONIGHT...A STRONG COLD FRONT WILL SWEEP THROUGH THE REGION FROM THE NORTH. SCATTERED THUNDERSTORMS WILL DEVELOP TOWARD THE MISSOURI BORDER DURING THE AFTERNOON HOURS...WITH THUNDERSTORMS LIKELY IN MOST AREAS TONIGHT AS THE FRONT SURGES SOUTHWARD. THERE SHOULD BE SOME SEVERE WEATHER...WITH DAMAGING STRAIGHT-LINE WINDS THE MAIN CONCERN. RAIN WILL BE WIDESPREAD...WITH AMOUNTS BETWEEN A QUARTER AND THREE QUARTERS OF AN INCH...AND LOCALLY BETWEEN ONE AND TWO INCHES. IT APPEARS THE HEAVIEST AMOUNTS WILL BE IN THE NORTHEAST WHERE RAIN IS NEEDED THE MOST DURING THIS CONTINUING DROUGHT. THE FRONT WILL EXIT TOWARD THE GULF COAST ON SATURDAY... WITH PERHAPS A LINGERING SHOWER EARLY IN THE SOUTHEAST. OTHERWISE...IT WILL CLEAR QUICKLY BEHIND THE FRONT...AND IT WILL FEEL A LOT COOLER. PARTS OF NORTHERN ARKANSAS WILL NOT GET OUT OF THE 70S...EVEN WITH FULL SUN. PARTS OF THE NORTHWEST COULD DIP INTO THE UPPER 40S SATURDAY NIGHT. TOWARD THE END OF THE PERIOD...A RIDGE OF HIGH PRESSURE WILL SLOWLY BUILD TOWARD ARKANSAS FROM THE SOUTHERN PLAINS. TEMPERATURES WILL START MODIFYING...BUT WILL STILL REMAIN A LITTLE BELOW NORMAL. LONG TERM...TUESDAY THROUGH THURSDAY A RIDGE OF HIGH PRESSURE WILL ANCHOR ITSELF OVER THE SOUTHEAST UNITED STATES IN THE EXTENDED PERIOD. THIS WILL KEEP THE REGION MOSTLY DRY AND WARM...AND TEMPERATURES WILL BE PRETTY CLOSE TO NORMAL. BY THURSDAY...A COLD FRONT WILL TRY TO PUSH INTO THE AREA FROM THE NORTHWEST. THE FRONT WILL ENCOUNTER THE RIDGE AND WILL LIKELY STALL. AT THIS TIME...LONG RANGE MODELS SHOW THE FRONT PENETRATING INTO THE STATE TOWARD NEXT WEEKEND WITH THE NEXT CHANCE OF RAIN. && .PRELIMINARY POINT TEMPS/POPS...
