AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 330 AM CST SAT DEC 13 2003 .DISCUSSION... BIG DIFFERENCES WILL BE PLAYING OUT TODAY ACROSS THE AREA. THE WARM SECTOR OF THE COLD FRONT DEVELOPING OVER THE NW GULF WILL NOT MAKE TO MUCH PROGRESS INLAND TODAY. THIS WILL KEEP SH/TS ACTIVITY OVER THE GULF AND COASTAL LOCATIONS WITH THE AREA BEING STACKED IN A 3 TIER STYLE. FROM NORTH TO SOUTH WILL KEEP 100% POPS ALL OVER BUT WILL KEEP ONLY RAIN NORTH...SHOWERS WITH ISOLATED TS OVER THE MID PORTION OF THE AREA...AND COASTAL INCLUDING NEW ORLEANS PROPER WILL GO WITH SH/TS. STRONG THETA-E GRADIENT EXISTS THIS MORNING AND THIS SHOULD BE THE CASE ALL DAY. MOISTURE WILL BE BROUGHT IN ALONG THE COAST DEVELOPING SFC BASED TS OVER THE NORTHERN GULF THEN TRANSITIONING INTO A LARGE AREA OF SHRA AS THE MOISTURE MOVES UP THE OE GRADIENT PRODUCING A LOT OF ELEVATED RAIN TODAY. A STRONG SHORT WAVE WILL MOVE IN AROUND LATE MORNING CAUSING SOME OF THESE TS ALONG THE COAST TO BECOME STRONG TO SEVERE AND WILL STACK THE HWO WITH THIS WORDING MAINLY FOR COASTAL LOCATIONS. PROLONGED RAIN EVENT TODAY MAY LEAD TO A FEW AREAS WITH STANDING WATER IN LOW LYING SPOTS BUT WIDESPREAD FLOODING PROBLEMS ARE NOT EXPECTED. THE MAIN EFFECT TODAY WILL BE COLD AND RAINY FOR MOST FOLKS ESPECIALLY SINCE THE DRY AIR AT THE SFC WILL HELP EVAPORATIONAL COOLING KEEPING THINGS RAW TO SAY THE LEAST. PERSONS ALONG THE COAST WILL ENDURE A DIFFENT ATMOSPHERE AS SHEAR AND SRH PROFILES GO THROUGH THE ROOF TODAY. STRONG STORM RELATIVE HELICITY VALUES FROM 400 TO 500 BEING PRODUCED BY STRONG DIRECTIONAL AND SPEED SHEAR IMMEDIATELY OFF THE SFC AND STORM MOTION PERPENDICULAR TO THE MEAN FLOW ALONG WITH A VERY LOW LCL AT AROUND 1000MB WILL HELP SOME OF THESE TS PRODUCE ISOLATED TORNADOES AND WATERSPOUTS. THE MAIN CONCERN FOR ALL THE NORTHERN GULF WILL BE HIGH WINDS ASSOCIATED WITH TS. WILL MENTION ALL 3 PROBLEMS THOUGH WITH TS ALONG THE COAST WITH WINDS...HAIL AND ISO TORS. WILL KEEP ONLY WINDS AND HAIL FOR COASTAL MISS COUNTIES THOUGH. && .PRELIMINARY POINT TEMPS/POPS...
