Area forecast discussion, Jun 21, 2:06 PM CST, 1 hour 39 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS LA 306 PM CDT SAT JUN 21 2008 .DISCUSSION... NOT MUCH HAS CHANGED SINCE THE LAST FORECAST PACKAGE...SO THIS DISCUSSION WILL BE SHORT AND SWEET. ONGOING CONVECTION IS EXPECTED TO LAST INTO THE FIRST PART OF THIS EVENING...BUT SHOULD DISSIPATE QUICKLY WITH THE LOSS OF DAYTIME HEATING. A MID AND UPPER LEVEL DRY LAYER IS EXPECTED TO FILTER INTO THE NORTHERN PART OF THE FORECAST AREA BY TOMORROW WHICH WILL LIMIT CONVECTION IN THOSE AREAS. HOWEVER...HAVE KEPT A SLIGHT CHANCE POPS SINCE A FEW ISOLATED SHOWERS AND THUNDERSTORMS MAY POP UP WITH FORECAST HIGHS NEAR THE MODEL FORECAST CONVECTIVE TEMPERATURES OF ABOUT 91. SOUTH OF THE INTERSTATE 10 CORRIDOR... THERE APPEARS TO BE ENOUGH LINGERING MOISTURE THAT CHANCE POPS WILL BE JUSTIFIED. GOING INTO MONDAY...THE UPPER LEVEL HIGH REALLY TAKES HOLD OF THE REGION CREATING A STRONG SUBSIDENCE INVERSION IN THE MID LEVELS. THIS WILL LIMIT CONVECTION TO ONLY SLIGHT CHANCES OF SHOWERS AND THUNDERSTORMS THROUGH THE WORK WEEK AND WILL KEEP AFTERNOON TEMPERATURES ABOUT FIVE DEGREES ABOVE NORMAL IN THE MID 90S MOST PLACES. && .AVIATION... SCATTERED CONVECTION MAY IMPACT EACH TAF SITE THROUGH THE AFTERNOON AND INTO THE EARLY EVENING HOURS.
