Area forecast discussion, Mar 22, 3:30 AM CST, 2 hours 21 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NEW ORLEANS LA 330 AM CST TUE MAR 22 2005 .UPDATE... UPDATED ZONES TO REFLECT TORNADO WATCH 63 IN EFFECT UNTIL 19Z. .PREVIOUS DISCUSSION...IN THE SHORT TERM...MAIN CONCERN WILL BE FOR CONVECTIVE POTENTIAL ACROSS THE CWA. AT THIS TIME...A SLIGHT RISK OF SEVERE WEATHER EXISTS ACROSS MOST OF SOUTHEAST LOUISIANA AND SOUTH MISSISSIPPI. HOWEVER...THE HIGHEST POTENTIAL FOR SEVERE THUNDERSTORMS WILL EXIST MAINLY NORTH OF THE I-12 CORRIDOR...AS BEST DYNAMICAL SUPPORT WILL REMAIN NORTH OF THE CWA INTO CENTRAL MISSISSIPPI. A VERTICALLY STACKED LOW PRESSURE SYSTEM IN EASTERN OKLAHOMA WILL CONTINUE TO MOVE TO THE EAST ACROSS ARKANSAS AND THE TENNESSEE VALLEY TODAY. IN THE UPPER LEVEL OF THE ATMOSPHERE...A HIGHLY DIVERGENT PATTERN WILL REMAIN IN PLACE OVER LOUISIANA AND MISSISSIPPI THROUGH THE EARLY MORNING HOURS...ALLOWING FOR STRONG FORCING AND DEEP LIFT TO REMAIN ENTRENCHED OVER THE REGION. A HIGHLY SHEARED WIND PROFILE...AND AMPLE LOW LEVEL MOISTURE WILL ALLOW THE THUNDERSTORMS TO REMAIN SEVERE AS THEY MOVE INTO THE REGION BETWEEN 5 AND 10 AM THIS MORNING...ESPECIALLY OVER THE NORTHERN AND CENTRAL CWA. 06Z SOUNDING INDICATES 0-3KM SRH VALUES IN THE 300 M2/S2 RANGE. EXPECT THESE HIGH HELICITY VALUES TO CONTINUE INTO THE MORNING...AND COULD ENHANCE AS FLOW BECOMES MORE BACKED IN THE LOW LEVELS. ALSO...0-3KM SHEAR OF 30 KNOTS IS INDICATED OVER THE AREA. AS A RESULT...DO EXPECT HAIL AND A FEW TORNADOES TO DEVELOP...ESPECIALLY IN STORMS IN ADVANCE OF THE MAIN SQUALL LINE. DAMAGING WIND THREAT WILL ALSO ACCOMPANY THE MAIN SQUALL LINE...AS DRY PUNCH IN THE MIDLEVELS AND 75KT 5H JET STREAK DEVELOP OVER THE REGION. MORE ISOLATED...MOST LIKELY NON-SEVERE...CONVECTIVE ACTIVITY CAN BE EXPECTED TO THE SOUTH OF THE I-12 CORRIDOR EARLY THIS MORNING. IT APPEARS THE CONVECTIVE THREAT WILL PUSH TO THE EAST OF THE REGION BY 10 AM THIS MORNING. BY MIDDAY...EXPECT STRONG SUBSIDENCE TO BUILD ACROSS THE AREA...AND REMAIN IN PLACE THROUGH EARLY SATURDAY MORNING...AS A RIDGE OF HIGH PRESSURE SETTLES INTO THE REGION. HOWEVER...ANOTHER SYSTEM WILL DEVELOP IN THE SOUTHERN PLAINS LATE SATURDAY...AND SLIDE THROUGH THE REGION SATURDAY NIGHT INTO EARLY SUNDAY. ANOTHER ROUND OF THUNDERSTORMS CAN BE EXPECTED WITH THIS SYSTEM AS IT MOVES THROUGH.
