NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 3, 10:15 AM CST, 2 hours 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 1115 AM CDT MON AUG 3 2009 .UPDATE...LOCAL RADARS WERE QUIET THIS MORNING FOR THE FIRST TIME IN AWHILE. THE JAN 12Z SOUNDING WAS DRIER WITH A PW AROUND AN INCH AND A HALF AND A DECENT CAP JUST ABOVE 700MB. HOWEVER DECENT LOW LEVEL MOISTURE REMAINS OVER THE AREA AND A CU FIELD WAS ALREADY DEVELOPING FROM THE EAST. A COUPLE OF ISOLATED SHOWERS HAVE DEVELOPED OVER SOUTHEAST MISSISSIPPIA AND WERE MOVING EAST INTO ALABAMA. CONSIDERING THE LIX SOUNDING AND THE AVAILABLE MOISTURE HAVE OPTED TO INCLUDE ISOLATED POPS OVER OUR SOUTHEAST ZONES FOR THIS AFTERNOON. SATELLITE IMAGERY/RUC ANALYSIS SHOWED A DECENT SHORTWAVE OVER THE MID MISSISSIPPI VALLEY EXTENDING SOUTH INTO CENTRAL ARKANSAS. A FEW THUNDERSTORMS WERE NOTED ON REGIONAL RADARS OVER CENTRAL ARKANSAS. THESE STORMS WILL LIKELY RIDE ESE ALONG THE OLD STATIONARY FRONT THAT HAS DRIFTED NORTH OF THE TENNESSEE-MISSISSIPPI STATE LINE. HOWEVER...HAVE OPTED TO INCLUDE MENTION OF ISOLATED COVERAGE LATE THIS AFTERNOON IN OUR NORTHERN TIER ZONES IN CASE OF AN OUTFLOW BOUNDARY AND/OR A LITTLE FARTHER SE TRACK. ALSO...DESPITE OUR WET SOILS...UNDER GOOD INSOLATION THIS MORNING TEMPERATURES HAVE RISEN MORE RAPIDLY THAN EXPECTED. UPPER 80S WERE OBSERVED AT MOST SITES AT 11 AM. PREVIOUS GUIDANCE MAX TEMPS WERE TRIMMED SO HAVE INCREASED AFTERNOON TEMP FORECAST BY A COUPLE OF DEGREES AT MOST SITES. /22/ && .PREVIOUS DISCUSSION...SHORT TERM...NEXT 48HRS WILL BE RATHER QUIET COMPARED TO WHAT THE PAST WEEK OR TWO HAVE BROUGHT. MAIN FOCUS OF THIS SHORT TERM (48HRS) WILL BE ON HIGH TEMPS AS CONVECTION LOOKS TO BE HELD AT BAY AND THE AREA IS ALLOWED TO DRY UP SOME. AIRMASS OVER THE REGION IS MUCH DRIER THAN WHAT WE HAVE BEEN SEEING AND PWS ARE RUNNING 1.4 TO 1.55 THIS EARLY MORNING. LOOK FOR SIMILAR MOISTURE CONTENT TO REMAIN WITH ONLY A TAD INCREASE CLOSER TO 1.6 BY TUE. OVERALL...THAT MOISTURE IS NOT GOOD ENOUGH THIS TIME OF YEAR TO SUPPORT CONVECTION UNLESS A DECENT S/W MOVES BY. AT THIS POINT...ALL THE MID/UPPER SUPPORT WILL STAY N/NE OF THE REGION AS WE REMAIN ON THE EASTERN EDGE OF A BUILDING UPPER RIDGE. AS FOR TEMPS THROUGH TUE...THE MODELS CONTINUE TO OFFER MID 90S FOR HIGHS AS THEY TRY AND PUSH IN WARMER 850MB TEMPS FROM THE WEST. I DONT ARGUE THAT THOSE WARMER LOW LEVEL TEMPS WILL SPREAD OUR WAY...BUT I FEEL THAT THE MOS IS NOT HANDLING OUR WET GROUND CONDITIONS AND IS WAY TOO WARM. BASED OFF AREA TEMPS SUN AND READINGS JUST TO OUR WEST...LOWER 90S SHOULD BE ALL WE CAN MUSTER TODAY. AS FOR TUE...I CAN SEE 1-2 DEGREES WARMER BUT GUID WAS STILL TOO AGGRESSIVE. AS A RESULT...I HAVE CUT HIGH TEMPS 1-4 DEGREES FOR VARIOUS SITES EACH DAY. WE WILL HAVE TO KEEP AN EYE ON HOW DEWPTS REACT AS THEY MAY SUPPORT HEAT INDICES AROUND 105 BY TUE. /CME/ .LONG TERM...WEDNESDAY THROUGH MONDAY...SOME OF THE MODELS AND ENSEMBLES SHOW THAT SEVERAL DISTURBANCES COMING IN NORTHERLY FLOW WILL AFFECT THE REGION. THE FIRST WILL COME ON WEDNESDAY. THE MID TO UPPER LEVELS WILL BE RATHER COOL WITH 500 MB -7 TO -9C AND 300 MB TEMPS AROUND -35C. ALSO AN UPPER JET OF AROUND 40 KNOTS AT THE LEFT FRONT QUAD WILL MOVE ACROSS THE REGION. THIS WILL PROVIDE SOME DECENT LAPSE RATES FOR A POSSIBLE MCS TO COME INTO THE REGION FROM THE NORTH. THERE WILL ALSO BE A BOUNDARY ACROSS NORTH MISSISSIPPI. THERE COULD BE SOME STRONG TO SEVERE STORMS WITH THIS MCS COMING FROM THE NORTH ON WEDNESDAY. ALL THE MODELS GENERALLY FAVOR IT. AREA SOUNDINGS SHOW DEEP ELEVATED CAPE...WHICH COULD INTENSIFY THE MCS COMING FROM THE NORTH. MODEL SOUNDINGS SHOW GOOD LAPSE RATES AND COOLING ALOFT FROM THE WARM SURFACE. THE SECOND DISTURBANCE WILL AFFECT THE REGION IN NORTHWEST FLOW ON THURSDAY INTO FRIDAY. THERE WILL BE A STATIONARY SURFACE BOUNDARY WELL NORTH OF THE REGION. GFS SHOWS THAT A TUTT LOW WILL DEVELOP OFF THE LOUISIANA COAST IN THE MIDDLE OF THE WEEK. THIS WILL HELP WITH MOISTURE INFLOW FOR CONVECTIVE CHANCES. MODELS ARE RATHER LIGHT WITH THE QPF AMOUNTS WITH THIS SYSTEM...BUT WITH THE MOIST ATMOSPHERE COULD GET SOME LOCAL DOWNPOURS. THIS LOW WILL MOVE WEST ON FRIDAY INTO SATURDAY THEN TRACK NORTHWEST. THE UPPER RIDGE WILL BUILD ACROSS THE REGION FROM THE EAST ON SATURDAY THROUGH MONDAY. THE GFS TRIES TO PUSH IT UP TO NEAR 600 DKM BY THE END OF THE WEEKEND. ALL THE MODELS AND ENSEMBLES BUILD THE UPPER RIDGE OVER THE REGION AFTER THE DISTURBANCE FOR FRIDAY THROUGH MONDAY. SO WITH THIS UPPER RIDGE THE STORM TRACK WILL MOVE BACK TO THE NORTHERN PORTION OF THE US. THIS WILL LEAD TO A DRIER PATTERN AS WE MOVE INTO THE WEEKEND. WITH THE DEVELOPMENT OF THE STRONG UPPER RIDGE OUR AFTERNOON TEMPS WILL GET INTO THE LOWER TO MIDDLE 90S. MOS NUMBERS ARE PRETTY LOW WITH THE TWO DISTURBANCES. BUT NOT CONFIDENT ABOUT THE PROG NUMBERS ESPECIALLY FOR THE DISTURBANCES BEFORE THE UPPER RIDGE SETS UP. THE AIR MASS WILL REMAIN SOMEWHAT MOIST AND UNSTABLE AND AT LEAST ISOLATED AFTERNOON CONVECTION CAN NOT BE RULED OUT. THE POSSIBILITY OF MCS ACTIVITY TRACKING IN FROM THE N WILL NEED TO BE MONITORED FOR WEDNESDAY THROUGH FRIDAY. AFTERNOON HIGH TEMPERATURES HAVE BEEN ADJUSTED SLIGHTLY COOLER FOR WEDNESDAY THROUGH FRIDAY BUT GENERALLY MAINTAINED LOW-MID 90S ACROSS THE AREA. ADJUSTED HIGHS SLIGHTLY COOLER FOR THU DUE TO THE WEAK WAVES THAT DROPS INTO THE REGION AND FOR OTHER DAYS BECAUSE OF SOGGY SOIL CONDITIONS THAT WILL PERSIST TO SLIGHTLY HAMPER COOLING. LEFT TEMPS MORE IN LINE WITH MOS INTO THE WEEKEND AS LOWER RAIN CHANCES THIS WEEK WILL HELP WITH DRIER SOIL CONDITIONS BY THEN./17/ && .AVIATION...VISIBILITIES HAVE IMPROVED AT ALL TAF SITES THIS MORNING FROM THE PATCHY FOG THAT DEVELOP EARLIER THIS MORNING. FOR THE REMAINDER OF THE DAY...LOOK FOR VFR CONDITIONS TO PREVAIL AT ALL TAF SITES. ANOTHER ROUND OF MVFR VISIBILITIES WILL BE POSSIBLE EARLY TUESDAY MORNING AS PATCHY FOG WILL DEVELOP ONCE AGAIN TOWARD DAY BREAK. /19/ && .PRELIMINARY POINT TEMPS/POPS...
