NWS Jackson, MS wrote its last area forecast discussion before the first event at Sep 2, 9:52 AM CST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 1052 AM CDT TUE SEP 2 2014 .UPDATE... SOME ADJUSTMENTS WERE MADE TO THE POPS AND QPF FOR THIS AFTERNOON AND EVENING...AND MINOR ADJUSTMENTS WERE MADE TO TEMPERATURES. ALL ELSE IS GENERALLY ON TRACK. && .DISCUSSION...A DIFFICULT FORECAST SCENARIO EXISTS FOR TODAY AS CONVECTIVE OUTFLOW PUSHES SOUTH ACROSS ARKANSAS AND TOWARD NORTHWEST PORTIONS OF THE ARKLAMISS...WHILE THE BEST LOW LEVEL CONVERGENCE SETS UP GENERALLY ALONG THE NATCHEZ TRACE CORRIDOR. THIS PATTERN IS RESULTING IN LOW LEVEL DRY AIR ADVECTION AHEAD OF THE SOUTHWARD MOVING BOUNDARY AND THIS MAY LIMIT CONVECTIVE DEVELOPMENT LATER THIS AFTERNOON OVER PORTIONS OF NORTHEAST LOUISIANA INTO WESTERN MS. HOWEVER...BASED ON THE LATEST HRRR AND LOCAL WRF GUIDANCE...EXPECT CONSIDERABLE SHOWER/TSTM DEVELOPMENT ALONG THE SAID MOIST-CONVERGENCE AXIS WHERE PRECIPITABLE WATER IN EXCESS OF TWO INCHES AND SB CAPE ~3500 J/KG WILL EXIST. LAPSE RATES WILL BE MARGINAL FOR GETTING A FEW SEVERE STORMS. OVERALL... HAVE ADJUSTED POPS TO BETTER REFLECT THE ABOVE SCENARIO... INCREASED THEM EAST AND DECREASED THEM OVER PORTIONS OF THE LA/MS DELTA REGION...BUT THIS IS NOT A HIGH CONFIDENCE FORECAST GIVEN 10-15 KTS OF LOW LEVEL FLOW AND NUMEROUS OUTFLOW BOUNDARIES LIKELY TO EXIST. /EC/ && .AVIATION...CEILINGS WERE SLOWLY LIFTING ACROSS THE REGION...WITH MVFR CONDITIONS AT MOST LOCATIONS. THROUGH NOON...LOOK FOR CEILING TO CONTINUE TO LIFT. SHOWERS WILL REMAIN IN THE VICINITY OF JACKSON GOING INTO THE AFTERNOON. WITH CLOUDS LINGERING OVER THE AREA...NOT SURE HOW MUCH THUNDER WILL BE AROUND...BUT WILL CONTINUE THE VCTS FROM 20-24Z. A BOUNDARY OFF TO NORTHWEST WAS SLOWLY MOVING IN THIS DIRECTION...BUT MODELS SUGGEST IT WILL NOT MAKE IT THIS FAR SOUTH. MODELS SEEM TO DISAGREE ABOUT FOG DEVELOPMENT FOR TONIGHT BUT AGREE STRATUS SHOULD NOT DEVELOP. WILL ADD PATCHY FOG TO ALL SITES FROM 8-12Z. && .PREV DISCUSSION... /ISSUED 351 AM CDT TUE SEP 2 2014/ DISCUSSION... TODAY THROUGH WEDNESDAY GREATER COVERAGE OF SHOWERS AND THUNDERSTORMS EXPECTED TODAY VS. YESTERDAY WITH SOME POSSIBLY ON THE STRONG TO BRIEFLY SEVERE SIDE IN WEST AND SOUTHWEST AREAS. TEMPERATURES WILL RISE QUICKLY THROUGH MORNING HOURS BUT BE TEMPERED BY SHOWER COVERAGE DURING THE AFTN. A SWIFT MOVING S/WV TROUGH ACROSS THE CENTRAL PLAINS IS SUSTAINING A MCS IN KS/OK/MO THIS MORNING AND IS ACTING TO FLATTEN THE ALREADY WEAK H7-H5 RIDGING OVER THE LOWER MS VALLEY. HI-RES GUIDANCE INDICATES THE MCS WILL SHIFT INTO OK/AR THROUGH THE DAWN HOURS AND SLOWLY WEAKEN AS IT GUSTS OUT. HOWEVER, HRRR/ARW SUGGEST A CONVERGENT BAND DEVELOPING FROM THIS OUTFLOW IN SOUTH AR AND NORTH LA BY LATE MORNING TO EARLY AFTN THAT COULD SERVE AS A FOCUS FOR MORE ORGANIZED ACTIVITY INTO WEST AND SOUTHWEST MS BY MID TO LATE AFTN. AHEAD OF THIS BOUNDARY, IT SHOULD ALSO BE NOTED THAT WITH SUCH A WARM START THIS MORNING, CONVECTIVE TEMPERATURES WILL BE REACHED 11AM-12PM AND ISO/SCT SHOWERS/TSTORMS WILL LIKELY DEVELOP ACROSS THE I-20 AND HWY 82 CORRIDORS. GREATER INSTABILITY WILL EXIST IN WEST IN CONJUNCTION WITH POSSIBLE CONVERGENCE BAND AND THIS MAY PROMOTE BETTER UPDRAFT STRENGTH AS SUPPORTED BY SPC SSEO OUTPUT. STORMS COULD BECOME STRONG TO BRIEFLY SEVERE WITH LOCALIZED WINDS IN THE 40-60 MPH RANGE AND FREQUENT LIGHTNING. WILL NOT FORMALLY INTRODUCE A LIMITED THREAT OF SEVERE JUST YET AS TO MONITOR HI-RES TRENDS AND ALLOW FOR MORNING SOUNDING ANALYSIS. SHOWERS/STORMS WILL DIMINISH THROUGH THE MID EVENING HOURS BUT SOME NEW ACTIVITY MAY DEVELOP IN NORTH MS ALONG AN ELEVATED BOUNDARY EARLY WEDNESDAY MORNING AND HAVE PLACED 20% POPS FOR FAR NORTH TIER COUNTIES. PWATS NEAR 2" WILL CONTINUE WEDNESDAY WITH ANOTHER ROUND OF SHOWERS/STORMS EXPECTED DURING THE AFTERNOON HOURS. THIS ACTIVITY ALSO SHOULD DECREASE THROUGH MID EVENING HOURS WITH QUIET CONDITIONS OVERNIGHT THURSDAY EXPECTED. /ALLEN/ THURSDAY THROUGH MONDAY... DEEP LAYERED RIDGE LOOKS TO REMAIN ANCHORED OVER THE LOWER CONUS THROUGH THE PERIOD. THIS SHOULD KEEP THE MOIST AND UNSTABLE AIRMASS LOCKED IN PLACE AND A CONTINUATION OF THE SENSIBLE WEATHER WE HAVE BEEN EXPERIENCING. WILL PRETTY MUCH HAVE TO CONTEND WITH AFTERNOON/EVENING AIRMASS CONVECTION EACH DAY THROUGH THE EXTENDED TIME FRAME. ALTHOUGH CONVECTIVE COVERAGE SHOULD REMAIN SCATTERED...STORMS MAY BE SOMEWHAT MORE NUMEROUS OVER THE SOUTH WHERE INTERACTIONS WITH THE SEA BREEZE MAY BE ENCOUNTERED. WENT CLOSE TO GFS MOS MAXIMUMS WITH HIGHS IN THE LOW TO MID 90S AS BELIEVE THIS LEVEL OF WARMING WILL STILL BE LIKELY GIVEN MID AFTERNOON CONVECTIVE INITIATION TIMES. MOVING INTO THE WEEKEND...SUBTLE MID LEVEL TROFFINESS OVER THE EASTERN PORTIONS OF THE COUNTRY WILL ALLOW A WEAK COLD FRONT TO EASE INTO THE REGION FROM THE NORTH SATURDAY NIGHT/SUNDAY. THE BOUNDARY LOOKS AS THOUGH IT WILL QUICKLY STALL OVER THE NORTH AND NOT OFFER ANYMORE THAN AN INCREASE IN CONVECTIVE COVERAGE FOR THE REMAINDER OF THE WEEKEND AND THE FIRST PART OF NEXT WEEK. WHILE THE COOL AIR BEHIND THE BOUNDARY SHOULD STAY TO THE NORTH OF THE AREA...INCREASED CONVECTION SUNDAY AND MONDAY SHOULD ONLY ALLOW MAXIMUMS TO REACH AROUND 90...BUT OVERNIGHT LOWS WILL REMAIN IN THE LOWER 70S./26/ && .PRELIMINARY POINT TEMPS/POPS...
