NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jun 12, 3:32 AM CST, 10 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS LA 432 AM CDT TUE JUN 12 2007 .DISCUSSION... MAIN FORECAST PROBLEM WILL AGAIN BE THE POPS AND WEATHER COVERAGE TODAY. THE MODEL POPS DRASTICALLY UNDERESTIMATED YESTERDAY/S ACTIVITY FORECASTING ONLY NEAR 10 PERCENT IN THE MOS WHILE THE ACTUAL VERIFICATION WAS IN THE 40 TO 50 PERCENT RANGE ACROSS THE INLAND ZONES. THE BASIC PATTERN IS SIMILAR TODAY AS WATER VAPOR LOOPS SHOW A BLOCKY PATTERN WITH ONLY SLIGHT NORTHEASTWARD MOVEMENT OF THE SHORTWAVE TROUGH OVER THE SOUTHWEST AND A SOUTHWARD PUSH OF THE EASTERN CONUS SHORTWAVE TROUGH AND ASSOCIATED NORTHWEST UPPER JET MAX THROUGH THE TN VALLEY/GA. AT THE SURFACE...LATEST ANALYSIS SHOWS A LEFTOVER WEAK FRONT ACROSS EXTREME SOUTH MS/ADJACENT SOUTHEAST LA WITH LOWER DEWPOINTS TO THE NORTH OF THE BOUNDARY. MODELS SUGGEST THE UPPER DIVERGENCE/ DIFFLUENCE MAY NOT BE AS PRONOUNCED AS YESTERDAY...BUT WATER VAPOR LOOPS SHOW A NICE SPLIT IN THE UPPER LEVEL WINDS. GIVEN ALL THESE FACTORS...AND WITH PW/S EXPECTED TO RANGE FROM 1.5 TO 2 INCHES... WILL GO ABOVE THE MOS POPS...GENERALLY 30 PERCENT NEAR THE COAST AND 40 PERCENT INLAND FOR LATE MORNING AND AFTERNOON. REFER TO THE AVIATION SECTION FOR MORE DETAILS ON TODAY/S CONVECTION. 850 MB TEMPS FORECAST IN 19 TO 20 C RANGE WILL AGAIN SUPPORT MID 90S FOR HIGHS BEFORE CONVECTION DEVELOPS WITH SOME UPPER 90S OVER INLAND SOUTHEAST MS. KPQL WAS 100 DEGREES YESTERDAY. HEAT ADVISORIES ARE NOT WARRANTED DUE TO EXPECTED COMBINATION OF RAIN COOLED AIR BY LATE AFTERNOON AND NIGHTTIME LOWS EXPECTED IN THE UPPER 60S TO MID 70S. SOME LEFTOVER ISOLATED SHOWERS AND STORMS MAY LINGER INTO THIS EVENING...ESPECIALLY SOUTH AND WEST. WEDNESDAY INTO FRIDAY...SLOW EASTWARD PROGRESSION OF SOUTHWEST SYSTEM INTO SOUTHERN PLAINS WILL TAKE PLACE AS EAST COAST SYSTEM CONTINUES TO MOVE SOUTH. EAST COAST SYSTEM WILL BRING NOTICEABLY COOLER HIGHS TO OUR AREA DUE TO 850 MB TEMPERATURES DROPPING A FEW DEGREES. MAY HAVE SOME DRIER CONDITIONS/LOWER POPS IN SOME AREAS THROUGH THE PERIOD DUE TO NARROW MID/UPPER RIDGE SANDWICHED OVER THE AREA...BUT WILL NOT INDICATE AS DRY AS THE MODELS. CONTINUED SLOW EASTWARD PROGRESSION OF SYSTEMS OVER THE WEEKEND WILL PROBABLY MAINTAIN STATUS QUO AS FAR AS SENSIBLE WEATHER...BUT POPS SHOULD INCREASE EARLY NEXT WEEK. && .AVIATION... CONDITIONS SEEM MORE FAVORABLE FOR THUNDERSTORMS AT THE TERMINALS WHEN COMPARED TO YESTERDAYS ACTIVITY AS HIGHER MOISTURE CONTENT AND A SLIGHTLY LOWER CONVECTIVE TEMPERATURE IS IN PLAY. EXPECTING CONVECTION TO INITIATE AROUND 91F TODAY...SOME TIME AROUND 16Z AND AFTER. WET MICROBURSTS WILL BE A CONCERN AS OUTFLOW GUSTS CAN BE 35 TO 45 KT. WILL BE UPDATING TAFS AT 12Z ISSUANCE TO INDICATE TEMPO G40KT 3SM TSRA BKN025CB AT KBTR AND KMCB MAINLY FROM 16Z-20Z...KMSY FROM 18Z-22Z AND MAY LEAVE PROB30 FOR KGPT AFTER 20Z AS THAT TERMINAL SHOULD HAVE LESS CHANCE OF CONVECTION. && .MARINE... LIGHT WIND FIELD SHOULD MAINTAIN LOW SEAS FOR NEXT FIVE DAYS. CONVECTION THAT DEVELOPS OVER LAND WILL BE UTILIZING MID 90S SURFACE HEATING...THEREBY LOSING THERMAL SUPPORT UPON APPROACHING THE NEAR COASTAL WATERS. CAN NOT RULE OUT AN OUTFLOW BOUNDARY THAT MAY PENETRATE THE SOUND WATERS AND INLAND LAKES AND BAYS WITH 30-35 KT GUSTS THIS AFTERNOON...BUT THIS SHOULD WASH OUT WITHIN A FEW MILES OFFSHORE. && .PRELIMINARY POINT TEMPS/POPS...
