ARS PREV DISCUSSION... /ISSUED 309 PM CST FRI NOV 30 2012/ NOT A LOT OF CHANGE TO THE PREVIOUS FORECAST THINKING FOR THE MIDSOUTH OVER THE NEXT 72 HOURS. A ZONAL FLOW ALOFT WILL PERSIST THROUGH SUNDAY WITH A COUPLE OF WEAK SHORTWAVES BRINGING CLOUDS AND A SLIGHT THREAT FOR A SHOWER OR STORM ACROSS THE NORTH. OTHERWISE THE MIDSOUTH WILL EXPERIENCE ABOVE NORMAL TEMPERATURES AND BREEZY SOUTH WINDS. IN FACT IT WILL FEEL MORE LIKE EARLY FALL ON SUNDAY AND MONDAY WITH TEMPERATURES IN THE LOW TO MID 70S AND DEWPOINTS NEAR 60F. TUESDAY...THE EURO AND GFS ARE STILL IN GOOD AGREEMENT THAT THE CURRENT STORM ALONG THE WEST COAST WILL PUSH ACROSS EAST OVER THE NORTHERN ROCKIES AND PLAINS...AND DRIVING A COLD FRONT THROUGH THE MIDSOUTH. TIMING OF THE FRONT IS STILL IN QUESTION THOUGH... WITH A FASTER AND MORE CONSISTENT GFS BRINGING PRECIP AS EARLY AS MONDAY EVENING AND ENDING IT BY TUESDAY EVENING. THE EURO ON THE OTHER HAND CONTINUES TO SLOW DOWN FROPA WITH RAIN BEGINNING EARLY TUESDAY MORNING AND PERSISTING ACROSS THE SOUTHERN MIDSOUTH COUNTIES INTO LATE WEDNESDAY. BOTH MODELS HOWEVER ARE AGREEING ON QPF AMOUNTS OF A HALF TO ONE INCH FOR MOST MIDSOUTH PATRONS...AND EMBEDDED T-STORMS. BOTH MODELS ARE ALSO SHOWING CAPE VALUES OF 200-600 J/KG AHEAD OF THE FRONT. THOUGH AN ISOLATED STRONG STORM CAN'T BE RULED OUT...BELIEVE THAT THE LIKELY THREAT WILL BE AN OCCASIONAL WIND GUST UNDER 35 MPH...SO WILL CONTINUE TO LEAVE OUT ANY MENTION IN THE HWO. WILL CONTINUE TO TAKE A BLEND ON MODEL TIMING WITH A SLIGHT LEAN TOWARD THE GFS...THAT IS...PRECIPITATION ENDING OVER THE SOUTH LATE TUESDAY NIGHT WITH SKIES CLEARING ON WEDNESDAY. EVEN WITH THE RAINFALL...TEMPERATURES ON TUESDAY SHOULD TOP OUT IN THE MID AND UPPER 60S AFTER A MILD MONDAY NIGHT. EXTENDED PERIOD. THE MODIFIED PACIFIC AIRMASS BEHIND THE FRONT...WILL KEEP TEMPERATURES SEASONAL IF NOT A FEW DEGREES ABOVE NORMAL FOR WEDNESDAY AND THURSDAY. CLOUDS WILL BEGIN RETURNING TO THE REGION THURSDAY NIGHT AS THE UPPER LEVEL WINDS BACK TO A MOIST SOUTHWEST FLOW. THIS IS IN RESPONSE TO ARCTIC AIR AND THE NEXT STORM DROPPING SOUTH FROM THE CANADIAN PRAIRIE PROVINCES. THE SOUTHERN EXTENT AND INTENSITY OF THIS AIRMASS IS STILL WELL IN QUESTION AS BOTH THE EURO AND GFS REMAIN OUT OF PHASE. FOR NOW HAVE INTRODUCED ONLY SLIGHT RAIN CHANCES FOR FRIDAY AND FRIDAY NIGHT ...BASED OFF THE ANTICIPATED WAA AHEAD OF A DEVELOPING CENTRAL PLAINS TROUGH.
