Area forecast discussion, Aug 22, 7:06 PM CDT, 1 hour 30 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE BIRMINGHAM AL 706 PM CDT MON AUG 22 2011 .UPDATE... FOR AVIATION. && .AVIATION... 00Z TAF DISCUSSION. DRIER AIR SHOULD CONTINUE TO SLOWLY FILTER IN OVERNIGHT... ESPECIALLY ACROSS THE NORTH. ALTHOUGH A FEW DECAYING TSRA STILL REMAIN ACROSS THE SOUTHERN FRINGES OF CENTRAL ALABAMA...EXPECTING WHAT IS LEFT OF THE ACTIVITY TO REMAIN AWAY FROM ALL TAF SITES... AND THIS TREND SHOULD CONTINUE AFTER SUNSET. ONLY MINOR BR IS EXPECTED FOR LATE TONIGHT WITH BEST CHANCES ACROSS THE SOUTH... CLOSER TO FRONT WHERE THE DRIER AIR HAS NOT QUITE MADE IT AS FAR YET. OTHERWISE...TOMORROW LOOKS GOOD WITH VFR CONDITIONS EXPECTED DURING THE DAY FOR ALL. 08/MNK && .PREV DISCUSSION... /ISSUED 347 PM CDT MON AUG 22 2011/ DISCUSSION... ANOTHER HOT DAY ACROSS CENTRAL ALABAMA WITH TEMPERATURES WELL INTO THE 90S. WE STILL REMAIN IN NORTHWEST FLOW ALOFT AND SATELLITE IS SHOWING A REMNANT MCS ROTATING DOWN THE EASTERN SIDE OF THE UPPER RIDGE THAT HAS BEEN SITUATED ACROSS THE SOUTHWESTERN US FOR MOST OF THE SUMMER NOW. A FEW SHOWERS STILL GETTING KICKED OFF BY THIS FEATURE AND ITS OUTFLOW AND WILL HAVE TO WATCH TO SEE IF ANY OF THESE MAY DRIFT INTO OUR NORTHERN COUNTIES. ELSEWHERE...A SURFACE TROUGH SITS ACROSS EXTREME SOUTHERN ALABAMA WITH A FEW SHOWERS IN OUR SOUTHERN COUNTIES THUS FAR. THIS BOUNDARY WILL CONTINUE TO SHIFT SOUTH THIS EVENING. WILL LEAVE A LOW END SLIGHT CHANCE POP TO COVER ANY LEFT OVER STORMS THROUGH THE EARLY EVENING. STILL EXPECTING TO SEE SOME LOWER DEW POINTS PUSH IN FROM THE NORTHEAST TOMORROW THAT SHOULD LOWER THE HUMIDITY LEVELS FOR A DAY OR TWO. OF COURSE THE MAIN WEATHER HEADLINE IS HURRICANE IRENE AND ITS POTENTIAL IMPACTS ON THE SOUTHEAST CONUS. 12Z MODEL TRENDS CONTINUE TO SHIFT THE STORM TO THE RIGHT THUS REMOVING ANY SIGNIFICANT INFLUENCE FOR ALABAMA. THE MAIN PLAYER IS THE UPPER TROUGH FORECAST TO PASS OVER THE EAST COAST THURSDAY WHICH SHOULD EFFECTIVELY CHANGE THE STORM TRAJECTORY MORE NORTHWARD FROM THE WESTERN BAHAMAS. WENT AHEAD AND REMOVED ANY MENTION OF RAIN FROM THE FORECAST AS THE STORM TRENDS ARE JUST TO FAR TO THE EAST NOW TO WARRANT EVEN ISOLATED POPS IN EASTERN ALABAMA. AS IRENE CONTINUES TO LIFT NORTHEASTWARD THIS WEEKEND...CENTRAL ALABAMA WILL REMAIN IN A NORTHWEST FLOW ALOFT. SURFACE FLOW WILL REMAIN NORTHERLY WITH NO RAIN CHANCES IN SIGHT. TEMPERATURES WILL BE IN THE 90S EACH AFTERNOON...ALTHOUGH IF ENOUGH CLOUD COVER GETS SHIFTED IN OUR DIRECTION FROM IRENE...SOME EASTERN COUNTIES MAY STAY IN THE 80S.
