NWS Jackson, MS wrote its last area forecast discussion before the first event at May 15, 9:54 AM CST, 3 hours 36 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 1054 AM CDT SAT MAY 15 2010 .UPDATE...STORMS ALREADY MOVING INTO THE FAR SOUTHWESTERN SECTIONS OF THE CWA THIS MORNING AS A VORT MAX OUT WEST BEGINS TO MOVE ACROSS OUR REGION. SOME OF THESE STORMS HAVE BECOME STRONG THIS MORNING ACROSS ADAMS COUNTY AND CATAHOULA AND CONCORDIA PARISHES (WITH EVEN A POTENTIAL TORNADO INTO LIX CWA EARLIER THIS MORNING). CANNOT RULE OUT THE POSSIBILITY FOR ONE OR TWO TO BECOME SVR THIS MORNING INTO THE AFTERNOON. WHILE FLOW IS NOT THAT IMPRESSIVE...THERE IS SOME MARGINALLY DECENT LAPSE RATES THAT COULD SUPPORT SOME LOWER-END HAIL AND...AS NOTED...HAVE UPDATED THE HWO FOR THIS THREAT AND THE HAZARD GRIDS. LOW LEVEL FLOW MAY INCREASE JUST A BIT THIS AFTERNOON FOR A SMALL TORNADO THREAT...WHICH HAS BEEN HIGHLIGHTED BY A 2% REGION FROM SPC IN THE SOUTHWEST. THE 12Z JAN SOUNDING IS NOT AS SUPPORTIVE FOR STRONG STORMS GIVEN CAPPING INVERSION...A BIT DRIER AND NOT AS UNSTABLE AS THE SOUNDINGS FURTHER TO OUR SOUTH(I.E. LIX). THAT BEING SAID...THINK THAT THE BEST STORMS WITH THE HIGHER POTENTIAL FOR STRONG TO ISOLATED SVR CHANCES WILL REMAIN FURTHER TO THE SOUTH(I.E. SOUTH OF I-20). FURTHER NORTH OF I-20...INSTABILITY LACKING A BIT MORE THOUGH RAIN AND POSSIBLY A THUNDERSTORM WILL BE POSSIBLE. LOCAL WRF MEMBERS SHOW CONVECTION BREAKING OUT ACROSS MUCH OF THE CWA...WITH THE BEST COVERAGE ACROSS THE SOUTH AND WEST. WILL KEEP HIGHEST POPS GOING IN THIS REGION. TEMPERATURES TODAY...DESPITE CLOUD COVER OVER THE REGION...SHOULD STILL BE ABLE TO REACH INTO THE MID 80S. HAVE UPDATED GRIDS TO TRY TO REFLECT CURRENT TRENDS AND THINKING FOR LATER TODAY. UPDATED PRODUCTS OUT SHORTLY. /28/ && .AVIATION...MAIN CONCERN FOR TODAY WILL BE CONVECTIVE POTENTIAL. EXPECT MAIN CONVECTIVE CONCERNS WILL BE AT KGLH/KJAN/KHBG AS CONVECTION BUILDS IN FROM THE S AND W AHEAD OF VORTICITY MAX CURRENTLY MOVING OUT OF LA. WILL SHOW AT LEAST TEMPO MVFR CONDITIONS DUE TO CONVECTION AT THESE TERMINALS BY 21Z. GUESSING IT WILL BE MORE DIFFICULT FOR CONVECTION TO MAKE IT TO THE TERMINALS FARTHER NE WITH LESS INSTABILITY AND RELATIVELY SLOW N/NE MOTION OF CONVECTION SO WILL BE LESS BULLISH AT KGWO/KMEI/KGTR. CONVECTION SHOULD DECREASE SOMEWHAT AFTER SUNSET...WITH CONCERN SHIFTING TO STRATUS/FOG POTENTIAL. MODELS NOT QUITE AS BULLISH ON STRATUS TONIGHT AS LOW LEVEL FLOW WEAKENS SOMEWHAT AND CONVECTIVE DEBRIS LIKELY LIMITS RADIATIONAL COOLING. WILL CONTINUE TO SHOW IFR CONDITIONS DEVELOPING AT KHBG BY 09Z AND AT KMEI/KJAN FOR A TIME BEFORE SUNRISE. SITUATION LESS CLEAR AT HIGHWAY 82 TERMINALS AND WILL LIKELY LEAVE THEIR FORECAST ABOVE IFR AT THIS POINT AND LET LATER FORECASTS REFINE THE SITUATION. /08/ && .PREV DISCUSSION... /ISSUED 930 AM CDT SAT MAY 15 2010/ UPDATE...HAVE UPDATED THE HWO TO ADD A MENTION OF STRONG STORMS TO THE SOUTHERN PART OF THE AREA FOR TODAY. SATELLITE SHOWS A MCS INDUCED VORTICITY MAXIMUM MOVING INTO THE AREA FROM THE WEST. AREA VAD WIND PROFILES AND THE LATEST RUC SUPPORT A VERY MODEST INCREASE IN MID LEVEL FLOW WITH THIS FEATURE WITH 500 MB WINDS OF 30-35 KT ACROSS THE AREA TODAY. VISIBLE SATELLITE SHOWS THAT ENOUGH SUN SHOULD BE SEEN AHEAD OF FEATURE TO RESULT IN TEMPS REACHING THE MID 80S. MODIFYING THE 12Z KLIX RAOB FOR 86/68 GIVES SBCAPE VALUES APPROACHING 3000 J/KG...MLCAPES OF 2000-2500 J/KG...WITH MID LEVEL LAPSE RATES AROUND 6.5 C/KM. WITH ALL OF THIS...WOULD EXPECT AT LEAST SOME SCATTERED STRONG STORM ACTIVITY TODAY. WOULD ACTUALLY GUESS THAT IF WE HAVE ANYTHING SEVERE TODAY IT WOULD PROBABLY BE FROM MARGINALLY SEVERE HAIL WITH KLIX WBZ HEIGHT AROUND 9500 FT AND MARGINALLY DECENT LAPSE RATES. DCAPE VALUES ARE RATHER MEAGER AND WET MICROBURST CHECKLIST NOT VERY SUPPORTIVE OF MUCH WIND POTENTIAL. DID HAVE A REPORT OF A POSSIBLE TORNADO IN KLIX CWA EARLIER THIS MORNING AND SPC DID ADD 2 PCT TORNADO RISK UP INTO OUR SOUTHERN SECTIONS. RUC SHOWS 15-20 KT 0-1 KM SHEAR TODAY SO THIS IS NOT A ZERO PROBABILITY...BUT WITH RATHER UNIDIRECTIONAL FLOW AND LOW HELICITY VALUES DID NOT FEEL RISK WAS SUFFICIENT TO MENTION IN PRODUCTS. 12Z KJAN SOUNDING MUCH LESS SUPPORTIVE OF ANY STRONG STORM ACTIVITY...AND RUC/LOCAL WRF ENSEMBLE NOT SHOWING MUCH INSTABILITY OR STRONG ACTIVITY N OF I-20. /08/ SHORT TERM...TODAY THROUGH SUNDAY NIGHT...MODELS HAVE COME IN WETTER FOR OUR AREA TODAY AND MORE RAIN IS IN STORE FOR SUNDAY. SURFACE ANALYSIS HAS A STALLED FRONTAL BOUNDARY STRETCHING FROM CENTRAL TEXAS ACROSS THE ARKLATEX AND INTO WESTERN TENNESSEE. THIS BOUNDARY IS EXPECTED TO REMAIN JUST NORTHWEST OF OUR CWA TODAY BUT A FEW DISTURBANCES ARE EXPECTED TO MOVE OVER THE BOUNDARY AND SPARK CONVECTION THAT WILL SPREAD ACROSS OUR CWA. WATER VAPOR IMAGERY/RUC ANALYSIS SHOWS A SIGNIFICANT DISTURBANCE OVER EAST CENTRAL TEXAS THAT IS PROGGED TO TRACK NORTHEAST AND OVER OUR CWA TODAY. THE BLOCKING HIGH PRESSURE SURFACE AND ALOFT THAT HAS BEEN OVER OUR REGION THE PAST SEVERAL DAYS WILL CONTINUE TO WEAKEN AND DEEPER MOISTURE IS EXPECTED TO MOVE BACK INTO OUR AREA. THE JAN 00Z SAT PW WAS AROUND AN INCH AND A QUARTER AND PWS BETWEEN AND INCH AND THREE QUARTERS TO TWO INCHES ARE EXPECTED BACK OVER OUR CWA BY THIS EVENING. THIS COMBINED WITH THE RELATIVELY SLOW MOVEMENT OF THE STORMS TODAY SHOULD LEAD TO THE POTENTIAL FOR LOCALLY HEAVY DOWNPOURS. LOCAL WRF ENSEMBLE FORECAST SHOWS MOST OF THE ACTIVITY WILL BE LIMITED TO WEST OF THE MISSISSIPPI RIVER THIS MORNING AND THEN SPREAD EAST THROUGH THE AFTERNOON. THE INCREASE IN CLOUDS AND RAIN CHANCES WILL HOLD MAX TEMPERATURES IN THE MID 80S TODAY. THERE WILL LIKELY BE A DECREASE IN CONVECTION THIS EVENING WITH THE LOSS OF DAYTIME HEATING BUT THE GFS AND ECMWF SUGGEST A DECENT AMOUNT OF NIGHTTIME ACTIVITY DUE IN PART TO ANOTHER DISTURBANCE MOVING ACROSS OUR AREA. THE CLOUDS AND RAIN OVERNIGHT WILL RESULT IN OVERNIGHT LOW TEMPERATURES REMAINING WELL ABOVE NORMAL IN THE MID TO UPPER 60S AT MOST SITES. SUNDAY THE MAIN UPPER LEVEL TROUGH WILL MOVE INTO THE CENTRAL CONUS AND HELP DEVELOP A SURFACE LOW OVER THE SOUTHERN PLAINS. THIS SURFACE LOW WILL MOVE TO THE NORTHEAST OVER THE OZARKS BY MID DAY AND OVER THE MIDDLE MISSISSIPPI RIVER VALLEY SUNDAY EVENING. MODELS HAVE COME IN MUCH FASTER WITH THE PROGRESSION OF THE ASSOCIATED COLD FRONT. THE COLD FRONT IS CURRENTLY EXPECTED TO MOVE INTO OUR DELTA REGION BY MIDNIGHT SUNDAY AND INTO THE CENTRAL PORTIONS OF OUR CWA BY DAYBREAK MONDAY. HAVE GONE ABOVE MAV GUIDANCE POPS SUNDAY NIGHT ESPECIALLY OVER OUR DELTA. WL HAVE A WARM AND HUMID AIRMASS IN PLACE AHEAD OF THE COLD FRONT SUNDAY. COVERAGE OF STORMS IS EXPECTED TO BE WIDESPREAD. A FEW STRONG STORMS WITH LOCALLY HEAVY RAIN WILL BE POSSIBLE SUNDAY AND SUNDAY EVENING BUT THE ANTICIPATED NEARLY MOIST ADIABATIC MID LEVEL LAPSE RATES AND WEAK DEEP LAYER SHEAR SHOULD LIMIT SEVERE STORM POTENTIAL. LIMITED INSOLATION SUNDAY WILL RESULT IN SLIGHTLY COOLER THAN NORMAL AFTERNOON HIGHS IN THE LOWER 80S WHILE ABOVE NORMAL TEMPERATURES REOCCUR SUNDAY NIGHT. GUIDANCE TEMPERATURES WERE CLOSE AND LEANED TOWARD THE MAV. /22/ LONG TERM...MONDAY THROUGH NEXT SATURDAY... LATEST RUNS OF THE OPERATIONAL GFS...GEFS...NAM...AND CMC ARE TRENDING MORE PROGRESSIVE IN BRINGING A COLD FRONT SOUTHWARD ACROSS THE CWA ON MONDAY. THIS IS IN RESPONSE TO AN INTENSIFYING LOW OVER THE OHIO VALLEY REGION...AND SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THE FRONT. WHILE MID-LEVEL LAPSE RATES BELOW 6 C/KM WILL LIMIT ROBUST UPDRAFTS SOMEWHAT...PREFRONTAL DCAPES OF OVER 1000 J/KG WILL PRESENT THE POTENTIAL FOR STRONG CONVECTIVE OUTFLOW WINDS. UNCERTAINTIES IN FRONTAL EVOLUTION AND DEGREE OF PREFRONTAL DESTABILIZATION PRECLUDE MENTION OF THIS RISK IN THE HAZARDOUS WEATHER OUTLOOK. POST-FRONTAL DRIER AIR WILL FILTER INTO THE REGION BY MONDAY EVENING AND WILL TEMPORARILY END PRECIP ACROSS THE CWA. HOWEVER...FOR TUESDAY AFTERNOON...GFS/GEM ARE INDICATING THE BOUNDARY SLOSHING BACK NORTHWARD AS A WARM FRONT AND OPENING UP A PLUME OF PWAT VALUES OF AROUND 1.6 INCHES INTO THE SOUTHWESTERN CWA. THUS...CHANCES FOR SHOWERS AND THUNDERSTORMS RETURN FOR TUESDAY AFTERNOON ACROSS THE SOUTHWEST. FOR TUESDAY NIGHT THROUGH THURSDAY NIGHT...UNCERTAINTIES GROW WITH REGARD TO THE EVOLUTION OF THE AFOREMENTIONED BOUNDARY AND PLACEMENT OF DEEPER MOISTURE. THE OPERATIONAL GFS DEPICTS A QUASI-STATIONARY FRONT REMAINING OVER THE SOUTHERN THIRD OF THE CWA WITH PERSISTENT WEST-NORTHWESTERLY FLOW ALOFT IN ASSOCIATION WITH A MID/UPPER RIDGE. THIS SOLUTION HAS BACKING FROM THE GFS ENSEMBLES. SUCH SOLUTIONS KEEP PRECIP CHANCES RESTRICTED TO THE SOUTHERN CWA. THE ECMWF IS INDICATING A SHORTWAVE TROUGH TRAVERSING THE REGION ON WEDNESDAY... WITH THE SURFACE BOUNDARY MOVING NORTHEASTWARD ACROSS THE REGION AND INCREASED MOISTURE SPREADING ACROSS THE CWA FOR MID/LATE WEEK. THIS SOLUTION SUGGESTS PRECIP ACROSS A LARGER PART OF THE CWA...AND HAS BACKING FROM SOME OF THE CMC ENSEMBLE MEMBERS. GIVEN THE UNCERTAINTY...THE GOING FORECAST FOLLOWS A BLEND OF MEX AND ENSEMBLE MOS GUIDANCE FOR PRECIP CHANCES...WITH SLIGHT CHANCES FOR SHOWERS AND STORMS ACROSS MUCH OF THE CWA. WEAK LOW/MID-LEVEL LAPSE RATES WILL LIMIT THE POTENTIAL FOR STRONG THUNDERSTORMS. FOR FRIDAY INTO SATURDAY...CHANCES FOR SHOWERS AND THUNDERSTORMS WILL INCREASE ACROSS MUCH OF THE CWA...AS NWP GUIDANCE CONSENSUS IS FOR DEEPER MOISTURE TO SPREAD ACROSS THE ENTIRE AREA WITH PWATS FROM 1.5 TO 1.7 INCHES. MODELS AGREE THAT DEEP-LAYER ASCENT FROM A PACIFIC SHORTWAVE TROUGH WILL MOVE ACROSS THE REGION SOMETIME BETWEEN FRIDAY AND SATURDAY BRINGING INCREASED PRECIP CHANCES. MODELS DISAGREE ON THE EXACT TIMING AND PLACEMENT OF THIS FEATURE...BUT DO AGREE THAT HIGHER PRECIP CHANCES WILL EXIST FOR FRIDAY INTO SATURDAY. INCREASING SBCAPE VALUES IN RESPONSE TO STEEPING LOW/MID-LEVEL LAPSE RATES WILL RESULT IN AN INCREASING POTENTIAL FOR STRONG STORMS FOR FRIDAY INTO SATURDAY...ESPECIALLY AS THE DEEP-LAYER FORCING AND MEAN FLOW GRADUALLY INCREASE. TEMPERATURES FOR THE PERIOD FOLLOW A BLEND OF MEX AND ENSEMBLE MOS GUIDANCE GIVEN THE UNCERTAINTY IN SURFACE BOUNDARY PLACEMENT. THIS BLEND YIELDS HIGH TEMPS FROM THE LOW TO MID 80S...AND LOW TEMPS FROM THE UPPER 50S TO THE MID 60S. /COHEN/ && .AVIATION... STRATUS BELOW 1000FT WAS DEVELOPING ACROSS THE SOUTHERN HALF OF THE AREA WITH CEILINGS AT OR BELOW 200FT BEING REPORTED AT PIB AND HBG. IFR TO LIFR CEILINGS ARE EXPECTED TO CONTINUE ACROSS THE SOUTH THROUGH 15Z THIS MORNING. CONDITIONS WILL BRIEFLY IMPROVE THROUGH 18Z BUT COVERAGE OF THUNDERSTORMS IS EXPECTED TO INCREASE FROM WEST TO EAST DURING THE AFTERNOON. VFR CONDITIONS WILL PREVAIL THIS EVENING AFTER DAYTIME CONVECTION DISSIPATES. THERE WILL REMAIN THE CHANCE FOR ADDITIONAL THUNDERSTORM DEVELOPMENT OVERNIGHT. IFR CEILINGS AND VISIBILITIES ARE EXPECTED TO DEVELOP BY 09Z SUNDAY ESPECIALLY IN AREAS THAT RECEIVE RAIN TODAY. /22/ && .PRELIMINARY POINT TEMPS/POPS...
