NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 19, 9:24 AM CST, 4 hours 23 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 1024 AM CDT WED AUG 19 2015 .UPDATE... THE WAVE OF TROPICAL MOISTURE IS CONTINUING TO SURGE NORTH- NORTHEASTWARD INTO OUR CWA THIS MORNING. THIS WOULD BE THE SOURCE OF ALL THE CLOUD COVER OVER THE AREA AND THE REASON WHY TEMPERATURES ARE STAYING PRETTY STABLE IN THE LOW 80S AT THIS TIME. HIGH TEMPS WERE CUT A FEW DEGREES TO KEEP HIGHS IN THE UPPER 80S TODAY. THE POPS LOOK PRETTY GOOD...ALTHOUGH AFTER LOOKING AT RECENT MODEL RUNS THE SEVERE CHANCES HAVE BEEN CUT BACK JUST A BIT. CONFIDENCE IN SEVERE STORMS IS NOT AS GREAT. IN THE SW...THE BLOB OF RAINFALL WILL KEEP THOSE AREAS PRETTY STABLE DESPITE A LITTLE BIT OF LIGHTNING BEING ASSOCIATED WITH IT ALREADY. AS TO THE NW ALONG AND AHEAD OF THE FRONT...THE MODELS ARE NOW HINTING THAT AFTER 00Z THE STORMS WILL START TO DWINDLE SO THEREFORE HAVE REMOVED THE ELEVATED THREAT AND STUCK WITH LIMITED. /10/ && .AVIATION... THERE ARE A FEW PATCHES OF IFR CIGS THIS MORNING WITH HIGHER CLOUD DECKS EXPANDING ACROSS THE AREA. SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED THIS AFTERNOON AT THE TAF SITES AND THE 18Z ISSUANCE WILL FOCUS ON TIMING AND ASSOCIATED RESTRICTIONS ASSOCIATED WITH THIS ACTIVITY. /SW/ && .PREV DISCUSSION... /ISSUED 449 AM CDT WED AUG 19 2015/ SHORT TERM...THERE IS A CHANCE OF SEVERE STORMS FROM TWO SYSTEMS TODAY AND TONIGHT. RIGHT NOW WINDS LOOK LIKE THE GREATEST RISK. AN UPPER WAVE LOOKS TO MOVE OUT OF THE GULF THIS MORNING...BRINGING A CHANCE OF STRONG TO SEVERE STORMS FOR THE ENTIRE AREA...BUT THE SOUTHERN HALF OF THE CWA WILL BE MORE LIKELY TO BE IMPACTED. CONVECTION WAS ALREADY BLOWING UP ALONG THE LOUISIANA COAST AND WAS EXPECTED TO SPREAD NORTH AND WEST THROUGH THE MORNING. THE COLD FRONT SHOULD MOVE INTO THE AREA TONIGHT. AHEAD OF THE BOUNDARY...MODELS SUGGEST A LINE OF STORMS MAY DEVELOP AND MOVE INTO THE NORTHWESTERN ZONES. THINKING THIS WILL BRING THE BETTER CHANCE OF SEVERE TO DELTA IN THE 2Z TO 6Z TIME FRAME. WHILE WE ARE NOT IN THE MOST FAVORABLE POSITION...BEING NEAR THE REAR EXIT REGION COULD ENHANCE STORM DEVELOPMENT NORTHWEST OF THE CWA. MODELS SOUNDING SUGGEST THERE WILL BE DECENT SURFACE BASED INSTABILITY...SO THERE SHOULD BE ENOUGH ENERGY TO MAINTAIN STORMS. FOR THE HWO DEFINITELY GOING WITH LIMITED ACROSS THE CWA FOR TODAY AND TONIGHT...WILL LOOK AT THE DELTA A LITTLE CLOSER FOR TONIGHT. IT LOOKS LIKE THE BOUNDARY WILL HANG UP AROUND HIGHWAY 82 AND LINGER THROUGH THURSDAY. FOR NOW IT LOOKS LIKE GENERALLY THUNDERSTORMS DEVELOPING ON THURSDAY. MODEL PW VALUES SUGGEST THERE COULD BE SOME HEAVY DOWNPOURS...WITH A BOUNDARY IN THE AREA WILL NEED TO LOOK AT FLASH FLOODING POTENTIAL. FOR NOW WILL HOLD ON ANY FLOODING IN THE HWO. HOWEVER...THINKING PONDING AND SOME LOCALIZED FLOODING WILL BE POSSIBLE FOR THE NORTHERN ZONES. GUIDANCE POPS AND TEMPS WERE GOOD. LONG TERM......FRIDAY THROUGH TUESDAY...A QUASI STATIONARY FRONTAL BOUNDARY WILL BE DRAPED OVER NORTHERN PORTIONS OF THE CWA AT THE BEGINNING OF THE PERIOD...BUT IT WONT BE AROUND LONG AS UPPER SUPPORT HAS PULLED AWAY AND UPPER RIDGE REESTABLISHES ITSELF OVER THE NORTHERN GULF OF MEXICO. FOR FRIDAY ANYWAY...PROXIMITY OF SURFACE BOUNDARY WILL PROMOTE ANOTHER CONVECTIVELY ACTIVE AFTERNOON OVER CENTRAL AND SOUTHERN SECTIONS. MID 20S VERTICAL TOTALS AND LESSENING WIND FIELDS SUGGESTS THAT THIS CONVECTION SHOULD REMAIN THE DISORGANIZED PULSE VARIETY. SURFACE BOUNDARY WILL MOVE NORTH OVERNIGHT FRIDAY LEAVING NO FOCUS FOR CONVECTION SATURDAY. PWATS STILL RUNNING NEAR 2 INCHES SHOULD SUPPORT A SCATTERING OF STORMS THOUGH. ONCE AGAIN...LIGHT FLOW PATTERN AS UPPER RIDGE SHIFTS WEST TOWARD TEXAS SHOULD PROMOTE ANOTHER DAY OF DISORGANIZED PULSE TYPE CONVECTION. RIDGE CENTER WILL PULL FURTHER WEST INTO TEXAS OVERNIGHT SATURDAY WITH INCREASED RIDGING OVER THE MID MS VALLEY. THIS WILL ALLOW A KINK/SHORTWAVE TO FORM OVER THE LOWER MS VALLEY FOR SUNDAY FOLLOWED IMMEDIATELY ON IT HEELS BY ANOTHER POTENT WAVE AND ITS TRAILING COLD FRONT. THIS ACTIVE FLOW PATTERN WILL ALLOW DEEP LAYER SHEAR TO INCREASE AS LAPSE RATES BECOME BETTER IN THE NW FLOW. AM STILL CONCERNED ABOUT ROBUST CONVECTION SUNDAY AND MONDAY AS THESE FEATURES INTERACT WITH THE AREA DURING MAX HEATING./26/ && .PRELIMINARY POINT TEMPS/POPS...
