Area forecast discussion, Aug 22, 6:30 PM CDT, 1 hour 55 minutes before
AREA FORECAST DISCUSSION...UPDATE TO AVIATION NATIONAL WEATHER SERVICE MOBILE AL 630 PM CDT MON AUG 22 2011 .AVIATION...(00Z ISSUANCE)GENERALLY VFR CONDITIONS EXPECTED... OUTSIDE OF CURRENT TSRA ACTIVITY. DRIER AIR IS EXPECTED TO PUSH TOWARDS THE FA TUESDAY AFTERNOON...BUT AM EXPECTING ANOTHER ROUND OF TSRA TO FIRE TUESDAY AFTERNOON OVER MOST OF THE AREA TUESDAY AFTERNOON. /16 && .SHORT TERM [TONIGHT THROUGH WEDNESDAY NIGHT]...UPPER TROUGH DIGGING DEEPLY OVER THE EAST COAST IS ORIGINATING FROM A RATHER INTENSE CLOSED LOW OVER EASTERN QUEBEC. THE EFFECTS ARE MAINLY IN THE MID ATLANTIC AND NEW ENGLAND STATES BUT IT SUPPORTS A WEAK SURFACE BOUNDARY TO DRIFT INTO OUR REGION. RAOBS TODAY INDICATE WE COULD HAVE A FEW STORMS WITH STRONG WINDS TO 40 MPH...FREQUENT LIGHTNING AND LOCALLY HEAVY RAIN...LINGERING INTO EARLY THIS EVENING. ON TUESDAY THROUGH WEDNESDAY NIGHT THE COLD FRONT WILL DISSIPATE ON WEDNESDAY SO WILL MAINTAIN A MAINLY DIURNAL TREND OF AFTERNOON AND EVENING ISOLATED SHOWERS AND THUNDERSTORMS BOTH DAYS. SURFACE HIGH OVER THE PIEDMONT WILL RETREAT OVER WESTLANT AS A RIDGE NOSING INTO THE CAROLINAS. QUASISTATIONARY UPPER RIDGE ALIGNED OVER THE FOUR CORNERS REGION IN THE SOUTHWEST WILL REMAIN THERE AND FORM A SADDLE POINT OVER THE PIEDMONT AND ERODE THE WESTLANT RIDGE A LITTLE BIT. THIS WOULD APPEAR TO BE A GATE FOR HURRICANE IRENE TO PASS THROUGH OVER THE PIEDMONT...BUT THAT WEAKNESS WILL DRIFT EAST AS THE WESTERN PART OF THE EASTERN UPPER RIDGE ERODES AWAY. HOT AND VERY HUMID CONDITIONS WILL PERSIST AS HIGHS CONTINUE TO PUSH ABOUT 3 TO 7 DEGREES ABOVE NORMAL DESPITE THE ADVANCING COLD FRONT. 77/BD && .LONG TERM [THURSDAY THROUGH MONDAY]...NO CHANGES. HOT TEMPERATURES REMAIN WITH HIGHS IN THE MID 90S INLAND AREAS AND LOWER 90S ALONG THE COAST. HEAT INDICES WILL CONTINUE TO RANGE FROM 98 AND 105 DEGREES EACH AFTERNOON THROUGH THE REMAINDER OF THE WEEK. LOW TEMPERATURES EACH NIGHT WILL RANGE FROM 70 TO 75 DEGREES INLAND AREAS AND 76 TO 80 DEGREES ALONG THE COAST. ISOLATED MAINLY AFTERNOON AND EARLY EVENING SHOWERS AND THUNDERSTORMS WILL ALSO CONTINUE EACH DAY. WE WILL ALSO CONTINUE TO MONITOR THE PROGRESS OF TROPICAL CYCLONE IRENE. THE LATEST OFFICIAL FORECAST HAS IRENE MAKING A TURN TOWARD THE NORTHWEST BY MIDWEEK...AND MOVING UP THE EASTERN FLORIDA COASTLINE THURSDAY NIGHT INTO FRIDAY. WE WILL CONTINUE TO MONITOR IRENE AND KEEP YOU UPDATED ON ANY CHANGES TO THE FORECAST TRACK. && .MARINE...HIGH PRESSURE CONTINUES TO WEAKEN OVER THE NORTHERN GULF OF MEXICO OVER THE NEXT SEVERAL DAYS AS WEAK TROF OF LOW PRESSURE BECOMES NEARLY STATIONARY NEAR THE COAST THROUGH LATE WEEK. LIGHT WEST TO NORTHWEST OVERNIGHT FLOW THROUGH WEDNESDAY...WITH LIGHT SOUTHWESTERLY FLOW IN THE AFTERNOON AND EARLY EVENING HOURS. BY THURSDAY AND INTO FRIDAY...HURRICANE IRENE IS EXPECTED TO BE MOVING UP THE EAST COAST OF FLORIDA...AND AS A RESULT A MODERATE WIND FLOW WILL BECOME MORE EASTERLY ON THURSDAY AND THEN MORE NORTHERLY ON FRIDAY. BY SATURDAY MODERATE WINDS OVER THE MARINE AREA WILL BECOME MORE WESTERLY IN THE WAKE OF IRENE AS THE CYCLONE CONTINUES MOVING NORTH ALONG THE US ATLANTIC COAST. 12/DS && .FIRE...A WEAK FRONT WILL STALL NEAR THE COAST LATE TONIGHT INTO TUESDAY. LIGHT WESTERLY WINDS AHEAD OF THE FRONT WILL BRING ELEVATED HUMIDITY THROUGH MONDAY. THE FRONT WILL BRING SOMEWHAT LOWER HUMIDITY TUESDAY. IT IS SUFFICIENTLY WEAK NOT TO DISRUPT THE SEABREEZE TOO MUCH...BUT JUST ENOUGH TO LIMIT RAIN COVERAGE TO ISOLATED THIS WEEK. MIXING HEIGHT WILL BE QUITE DEEP IN THE DAY...REACHING 9000 FEET IN PLACES. DISPERSION IN THE 60S EXCEPT IN THE 80S ALONG THE COAST...BUT WITH HUMIDITY IN THE 40S...THIS WILL NOT MEET FIRE WEATHER HEADLINE CRITERIA. BD/77 && .PRELIMINARY POINT TEMPS/POPS...
