NWS Jackson, MS wrote its last area forecast discussion before the first event at Dec 8, 6:23 PM CST, 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 623 PM CST SAT DEC 8 2012 .UPDATE... A COUPLE OF STRONG STORMS DEVELOPED DURING THE LATE AFTERNOON OVER THE DELTA REGION AND ARE CONTINUING INTO THE EARLY EVENING. HAVE UPDATED THE FORECAST TO EXTEND THUNDERSTORM RISK FOR A FEW MORE HOURS. /EC/ && .PREV DISCUSSION... /ISSUED 327 PM CST SAT DEC 8 2012/ SHORT TERM....TODAY THROUGH MONDAY NIGHT... A SHORT WAVE IS MOVING ACROSS THE NORTHERN PORTIONS OF THE AREA THIS AFTERNOON AND IS KICKING OFF FEW SHOWERS AND ISOLATED STORMS. THERE WILL BE SUFFICIENT MOISTURE FOR A FEW SHOWERS TO CONTINUE TO BE POSSIBLE THROUGH THE NIGHT ACROSS THE DELTA AND NORTHERN PORTIONS OF THE AREA...BUT THE MODELS SUGGEST MOST OF THE ACTIVITY WILL MOVE NORTH OF THE AREA. AREAS OF FOG WILL BE POSSIBLE MAINLY OVER THE SOUTHEASTERN PORTIONS OF THE AREA WHERE THE BOUNDARY LAYER WINDS WILL BE LIGHT ENOUGH...BUT EXPECT MAINLY STRATUS FURTHER NORTH AS THE WINDS WILL BE A BIT STRONGER. SUNDAY WILL BE A RELATIVELY QUIET DAY...BUT THERE WILL BE ENOUGH MOISTURE COMBINED WITH A FEW WEAK SHORT WAVES MOVING ACROSS THE DELTA FOR A FEW SHOWERS TO BE POSSIBLE IN THOSE AREAS. A DEEP UPPER TROUGH AND ASSOCIATED COLD FRONT WILL MOVE INTO THE DELTA LATE SUNDAY EVENING AND CONTINUE TO MOVE ACROSS THE AREA THROUGH THE NIGHT. THE MODELS CONTINUE TO INDICATE AROUND 25KT OF 0-1KM SHEAR AND SOME INSTABILITY WITH AROUND 100-300J/KG OF ML CAPE. THE WINDS ARE MAINLY GOING TO BE MAINLY UNIDIRECTIONAL OUT OF THE SOUTHWEST...SO EXPECT A SQUALL LINE TO MOVE THROUGH THE AREA...EXITING EAST OF THE AREA BY MID MONDAY AFTERNOON. WILL CONTINUE TO MENTION THE POSSIBILITY OF STRONG TO POSSIBLY SEVERE IN THE HWO ALONG WITH LOCALLY HEAVY DOWNPOURS. THE COLD FRONT WILL MOVE EAST OF THE AREA BY MID-LATE AFTERNOON WITH SOME LINGERING SHOWERS/CLOUDS IN THE SOUTHEAST POSSIBLE IN THE EARLY EVENING. DRIER/COLDER AIR WILL BUILD IN BEHIND THE FRONT WITH TEMPS FALLING INTO THE UPPER 20S TO MID 30S ACROSS MUCH OF THE AREA MONDAY NIGHT UNDER MAINLY CLEAR SKIES. STUCK PRETTY CLOSE TO GUIDANCE TEMPS THROUGH MUCH THE PERIOD...BUT DID WARM THEM SLIGHTLY ON SUNDAY AND AFTER LOOKING AT H925/H850 TEMPS AND CLIMO...ALSO CUT BELOW GUIDANCE LOWS MONDAY NIGHT. RAISED ABOVE GUIDANCE POPS SUNDAY NIGHT ACROSS MUCH OF THE AREA AND ALSO RAISED ON MONDAY IN THE EAST. DID NOT MAKE ANY CHANGES BEYOND MONDAY NIGHT...SO WILL ATTACH THE APPLICABLE PORTIONS OF THE PREVIOUS LONG TERM BELOW. /15/ PREVIOUS LONG TERM...FOR DAYTIME TUESDAY MODELS GENERALLY AGREE SOME CIRRUS STREAMING BACK IN FROM THE SOUTHWEST COULD LIMIT SUNSHINE SOMEWHAT IN THE SOUTHEAST HALF OF ZONES. THIS FACT...IN COMBO WITH LIMITED MIXING IN THE COLD AIR ADVECTION REGIME...PROMPTED ME TO LOWER MEX HIGH ACROSS THE BOARD BY 2 TO 4 DEGREES. THIS LEADS INTO DECENT RAD COOLING ANTICIPATED FOR TUESDAY NIGHT WHERE COLDER- TRENDING MEX LOWS (NOW MOSTLY IN THE MID TO UPPER 20S) LOOK GOOD. THEN WE COME TO WEDNESDAY AND WEDNESDAY NIGHT WHEN COOL AIR MASS WILL BE STILL LOCKED IN PLACE AT THE SURFACE BUT MODELS AGREE A DECENT H500 SHORT WAVE WILL MIGRATE THROUGH THE LOWER MS VALLEY. GFS/EURO EXPLICIT OPERATIONAL GUIDANCE NOW SUGGESTS ENOUGH MOISTURE FOR PRECIP PRODUCTION SHOULD REMAIN MOSTLY SHUNTED TO OUR SOUTH AND SOUTHEAST IN ASSOCIATION WITH THIS SYSTEM. HOWEVER...PREVIOUS OP EURO RUN AND LATEST GFSENSEMBLE GIVES INDICATION THAT AT LEAST LOW END CHANCES OF PRECIP IN MAINLY SOUTHEAST HALF OF ZONES CANNOT BE IGNORED. LATEST MEX MOS PLAYING IT TOO SAFE IT SEEMS WITH WIDESPREAD 20 TO 30 POPS AND INTERPRETATION OF ALL GUIDANCE MAKES IT MORE SENSIBLE TO CUT POPS 5 TO 15 POINTS IN ALL BY SOUTHEAST ZONES. GIVEN CHILLY AIR IN PLACE ONE MIGHT THINK WINTRY PRECIP COULD CONCEIVABLY BE A WORRY WITH THIS SYSTEM...BUT ALAS EXPECTED AFTERNOON INTO EVENING TIMING SHOULD ENSURE POTENTIAL FOR THIS IN OUR AREA IS EXTREMELY LOW. MEX TEMPS DROPPED A LITTLE WEDNESDAY BUT LOOK GOOD WEDNESDAY NIGHT. TEMPERATURE MODERATION SHOULD GET UNDERWAY THURSDAY AS FLOW TURNS AROUND QUICKLY TO SOUTHERLY IN REACTION TO WESTERN CONUS TROUGH ENERGY AND LOW PRESSURE FORMING IN THE PLAINS. MODELS START TO SHOW CONSIDERABLE DISAGREEMENT WITH HOW QUICKLY OR IN WHAT EXACT MANNER THIS ENERGY TRANSLATES EAST TOWARD OUR REGION THROUGH THE END OF THE WEEK. DECENT CONFIDENCE THAT RAIN CHANCES WILL ARRIVE BY SATURDAY...BUT AT LEAST A LITTLE POTENTIAL THEY COULD RETURN BY FRIDAY. TEMPERATURES WILL PROBABLY CONTINUE TO TREND UPWARD FROM THURSDAY UNTIL THE NEXT COLD FRONT PASSES...BUT THIS FRONTAL PASSAGE MIGHT COME AS EARLY AS NEXT SATURDAY. MEX TEMPS ACCEPTED COMPLETELY THURSDAY THROUGH SATURDAY...BUT THEY MAY TURN OUT TO BE TOO WARM...ESPECIALLY CONSIDERING STRONG HINTS OF -NAO TELECONNECTION DEVELOPING THROUGH THE LONG TERM PERIOD. /BB/ && .AVIATION... ISOLATED SHRA/TSRA PASSING NEWD THROUGH OUR NWRN PORTIONS OF THE CWFA THIS AFTERNOON...MAINLY W OF A GRENADA TO VICKSBURG TO NATCHEZ LINE. SOME OF THESE MAY PROGRESS AS FAR E AS THE NATCHEZ TRACE PARKWAY. OTHERWISE...VFR CLOUDS ARE EXPECTED TO PREVAIL AT ALL SITES THROUGH THE EVENING HOURS FOLLOWED BY AREAS OF DEVELOPING MVFR STRATUS 05-08Z...LOWERING TO IFR STRATUS/PATCHY FOG FROM 08-15Z...THEN SLOWLY LIFTING. WINDS WILL BE SSELY 6-12KTS... SUBSIDING TO ABOUT 6KTS OR LESS OVERNIGHT... EXCEPT IN THE DELTA. SLY WINDS WILL BE ON THE INCREASE LATE TONIGHT ALONG THE MS RIVER AND BE PICKING UP 12-18KTS AND GUSTY FOR MOST AREAS SUNDAY FROM MID MORNING THROUGH THE AFTERNOON.
