NWS New Orleans, LA wrote its last area forecast discussion before the first event at Dec 22, 7:00 PM CST, 45 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 700 PM CST WED DEC 22 2004 .UPDATED... REMOVED TORNADO WATCH FROM ENTIRE ZONE PACKAGE AS WELL AS SOFTENING WORDING FOR LINGERING LIGHT RAIN THROUGH ABOUT MIDNIGHT. NO POPS THIS PERIOD FOR ONGOING LIGHT RAIN BUT GENERAL IDEA IS IMPROVING TREND WITH PASSAGE OF THE FRONT. THE FRONTAL POSITION AT 7 PM APPEARS TO BE COLUMBIA MS...HAMMOND...PATTERSON MOVING SOUTHEAST AT 20 MPH. THIS SHOULD PLACE IT AROUND PICAYUNE...SLIDELL...KENNER... HOUMA LINE AT 9 PM AND FROM OCEAN SPRINGS TO POINTE A LA HACHE AT MIDNIGHT. 24 && .PREV DISCUSSION...THE MAIN FORECAST PROBLEMS CONTINUE TO BE THREAT OF STRONG TO SEVERE WEATHER LATE THIS AFTERNOON AND THIS EVENING FOLLOWED BY A FRIGID COLD SPELL BEGINNING THURSDAY NIGHT ALONG WITH THE CHANCE OF A WINTRY MIX FRIDAY AND FRIDAY NIGHT. SOME FAIRLY STRONG CONVECTION CONTINUES ACROSS THE GULF WATERS THIS AFTERNOON ALTHOUGH MOST LAND AREAS HAVE BEEN DRY OVER THE PAST FEW AREAS. THIS SHOULD CHANGE THOUGH IN A FEW HOURS AS THE ADVERTISED COLD FRONT CURRENTLY MOVING THROUGH THE WESTERN HALF OF LOUISIANA PUSHES INTO THE OUTLOOK AREA LATER THIS AFTERNOON. CONVECTION HAS BEEN FIRING ALONG AND JUST AHEAD OF THIS BOUNDARY AS IT MOVES EAST. THE DEGREE OF INSTABILITY THOUGH ACROSS THE CWA/PWA WILL BE THE KEY FACTOR AS TO THE EXTENT OF THE STORM INTENSITY. IF SOME DESTABILIZATION THOUGH DOES OCCUR AS IS EXPECTED...ESPECIALLY ACROSS THE SOUTHERN AND COASTAL ZONES...SHEAR PROFILES DO POINT TO A RISK OF STRONG DAMAGING WINDS AND HAIL AS THIS ACTIVITY SWEEPS THROUGH. THE FRONT SHOULD MOVE EAST OF THE FORECAST AREA BY MIDNIGHT AS THE COOLER AIR BEGINS TO FILTER INTO THE REGION. THE ARCTIC AIR MASS SHOULD THEN BE ENTRENCHED ACROSS THE REGION BY THURSDAY NIGHT WITH MORE FREEZE WARNINGS ANTICIPATED...WITH THE EXCEPTION OF MAYBE AREAS SOUTH OF LAKE PONTCHARTRAIN LEADING TOWARD THE SOUTHEAST LOUISIANA COASTAL SECTIONS. FREEZE WARNINGS THOUGH WILL LIKELY BE REQUIRED FOR ALL AREAS FRIDAY NIGHT AS SOME OF THE COLDEST TEMPERATURES OF THE SEASON IMPACT THE REGION. DANGEROUS WIND CHILL LEVELS ARE ALSO LIKELY DURING THIS TIME FRAME WITH VALUES IN SOME AREAS POTENTIALLY DROPPING INTO THE LOWER TEENS OR MAYBE EVEN SINGLE DIGITS. THE FRIGID WEATHER SHOULD CONTINUE THROUGH CHRISTMAS DAY BEFORE TEMPERATURES GRADUALLY BEGIN TO REBOUND ON SUNDAY. THE FINAL CHALLENGE INVOLVES THE POTENTIAL FOR A WINTRY MIX FRIDAY AND FRIDAY NIGHT. THE GFS REMAINS SOMEWHAT PERSISTENT WITH DEVELOPING A SURFACE LOW IN THE WESTERN GULF AND THEN TRACKING THE SYSTEM DUE EASTWARD WITH MOISTURE WORKING ITS WAY AROUND THE BACK SIDE OF THE SYSTEM IMPACTING THE LOWER HALF OF THE CENTRAL GULF COAST REGION. THIS MODEL THOUGH MAY BE TRENDING MORE AS AN OUTLIER COMPARED TO THE ETA...THE UKMET AND THE ECMWF WHICH HAS DRIER AIR FUNNELING DEEPER INTO THE NORTHERN GULF WITH LESS DEVELOPMENT OF A SURFACE WAVE. WILL LIKELY GO WITH A BLEND OF THE ETA AND THE GFS WHICH IS CLOSE TO THE CURRENT FORECAST RIGHT NOW...EXCEPT MAYBE TO BUMP UP PRECIP CHANCES TO THE LOW SCT CAT ACROSS THE SOUTHERN ZONES FRIDAY AND FRIDAY NIGHT. WHILE THE GFS THICKNESS VALUES ARE NOT OVERLY CONDUCIVE TO ALL WINTER PRECIP...MODEL SOUNDINGS DO SUGGEST THE POTENTIAL FOR A MIX OF LIGHT RAIN...SLEET AND/OR SNOW ACROSS THE SOUTHERN ZONES INCLUDING METRO NEW ORLEANS AND THE MISSISSIPPI GULF COAST. MAY ALSO SEE A FEW FLURRIES ACROSS THE NORTHERN ZONES ALTHOUGH PRECIP CHANCES WILL REMAIN IN THE SLIGHT CHANCE CAT AT BEST. && .PRELIMINARY POINT TEMPS/POPS...

A SMALL CRAFT ADVISORY IS IN EFFECT FOR THE TIDAL LAKES AND THE SOUTHEAST LOUISIANA AND MISSISSIPPI COASTAL WATERS.

WIND CHILL READINGS WILL FALL INTO THE SINGLE DIGITS ACROSS SOUTH MISSISSIPPI AND EAST CENTRAL LOUISIANA AND TEENS FOR SOUTHEAST LOUISIANA THURSDAY...FRIDAY AND SATURDAY NIGHT. A HARD FREEZE IS LIKELY FRIDAY NIGHT OVER MOST AREAS EXCEPT NEAR THE SOUTHEAST LOUISIANA COAST AND THE SOUTH SHORE OF LAKE PONTCHARTRAIN. LOWS IN THE LOWER TO MID 20S WILL BE COMMON. COMPUTER MODELS INDICATE THE POTENTIAL FOR A LOW PRESSURE AREA TO FORM IN THE WEST CENTRAL OR SOUTHWEST GULF OF MEXICO THURSDAY NIGHT WITH MOVEMENT TO THE EAST ACROSS THE CENTRAL OR SOUTH CENTRAL GULF FRIDAY AND SATURDAY. COLD TEMPERATURES ALONG WITH INCREASED MOISTURE ACROSS THE AREA COULD BRING A LIGHT WINTRY MIXTURE OF SNOW...SLEET AND RAIN ON FRIDAY AND FRIDAY NIGHT...MAINLY FROM THE SOUTHEAST LOUISIANA COAST...FROM WEST AND SOUTHWEST OF LAKE PONTCHARTRAIN...TO JUST NORTH OF LAKE PONTCHARTRAIN...TO THE MISSISSIPPI COAST. PRECIPITATION AMOUNTS ARE EXPECTED TO BE LIGHT WITH VERY LITTLE ACCUMULATION OF SNOW OR SLEET. RELATIVELY WARM GROUND AND AIR TEMPERATURES ABOVE FREEZING DURING THE PRECIPITATION SHOULD PREVENT ROADS FROM ICING OVER. HOWEVER...BRIDGES AND OVERPASSES COULD BE ICY AND TREACHEROUS FRIDAY NIGHT. ...MARINE HAZARDS... A SMALL CRAFT ADVISORY WILL REMAIN IN EFFECT MAINLY FOR THE GULF COASTAL WATERS THROUGH SATURDAY. STRONG NORTHERLY WINDS AROUND 20 TO 30 KNOTS ARE EXPECTED TO CONTINUE INTO SATURDAY. .SPOTTER INFORMATION STATEMENT...
