NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 7, 3:01 AM CST, 5 hours 59 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 401 AM CDT SAT AUG 7 2010 .SHORT TERM...ISOLATED SHOWERS AND THUNDERSTORMS NOTED OVER THE REGION THIS MORNING WILL INCREASE IN COVERAGE DURING THE DAY. WE HAVE LOST THE PROTECTION OF UPPER RIDGING AND SIT IN AN AREA OF WEAK FLOW BETWEEN UPPER HIGHS CENTERED OVER THE GULF AND WELL TO OUR WEST. A BROAD ZONE OF SURFACE CONVERGENCE WILL PERSIST ACROSS THE AREA TODAY. THE BEST LOW LEVEL CONVERGENCE IS INDICATED ACROSS THE DELTA REGION PER OBSERVATIONS THIS MORNING BUT IS FORECAST TO SETTLE ACROSS THE I-20 CORRIDOR THIS AFTERNOON. THE LOCATION OF LOW LEVEL CONVERGENCE WILL DICTATE THE PLACEMENT OF BETTER RAIN COVERAGE. MODELS GENERALLY AGREE IN PLACING BEST CONVERGENCE IN THE VICINITY OF THE I-20 CORRIDOR LATER TODAY SO HAVE NO SOLID REASON TO DISAGREE WITH MAV POSITIONING BEST RAIN CHANCES CENTRAL AND SOUTH TODAY. HARDER TO PLACE POSITION OF SURFACE FORCING FOR SUNDAY BUT IT LOOKS SLIGHTLY WEAKER WITH A MORE NWD TREND SO WILL KEEP GENERALLY SCT CONVECTION ACROSS THE REGION. PRECIPITABLE WATER REMAINS BETWEEN 2.0-2.5 INCHES THRU SUNDAY. THE AIR MASS WILL BE MARGINALLY UNSTABLE WITH CAPE VALUES AROUND 3000 THIS AFTERNOON AND VERTICAL TOTALS AROUND 24-25 DEGREES. WITH DCAPE VALUES MARGINAL AT BEST...CAN NOT RULE OUT ISOLATED STRONGER STORMS BUT WILL HOLD OUT OF HWO FOR NOW. STRONGER STORMS WILL PRODUCE FREQUENT LIGHTNING AND PERIODS OF HEAVIER RAINFALL. UPPER RIDGING WILL BE CENTERED OVER THE AREA SUNDAY AND SUNDAY NIGHT AND SHOULD RESULT IN A MORE DIURNAL FLAVOR TO CONVECTION...KEEPING THE AREA DRY SUNDAY NIGHT. 850 MB TEMPS WILL RANGE FROM 20-21 DEGREES AT MOST SITES TODAY AND SUNDAY...MAYBE NEAR 22 DEGREES NRN ZONES. UNDERCUT MOS MAX TEMPS A COUPLE DEGREES MOST PLACES FOR TODAY DUE TO EXPECTED CLOUD COVER...RAIN CHANCES AND THE FACT THAT HEIGHTS/TEMPS ALOFT STILL REMAIN RELATIVELY CONSERVATIVE THIS AFTERNOON. AS RIDGING WILL BE IN THE DEVELOPING STAGES SUNDAY AND 850/925 TEMPS REMAIN CLOSE OR SLIGHTLY WARMER SUNDAY THAN SATURDAY...THE WARMING TREND SUGGESTED BY MOS FOR SUNDAY LOOKS GOOD. HAVE SLIGHT RESERVATIONS REGARDING UPPER 90S IN NRN ZONES BY SUNDAY AFTERNOON BUT THE AREAS WITH THE BEST POTENTIAL FOR WARMING WILL BE THOSE AREAS AND WILL FOLLOW MOS WITH THAT FOR NOW. WILL SEE SOME LOCATIONS CLIMB TO MARGINAL HEAT ADVISORY CRITERIA TODAY BUT...WITH CONVECTION DEVELOPING AND DRIER DEWPOINTS OBSERVED JUST TO OUR NORTH POSSIBLY DROPPING INTO NERN ZONES...WILL HOLD OFF ON A HEAT ADVISORY FOR TODAY. CONDITIONS LOOK MORE LIKELY FOR HEAT ADVISORY CRITERIA FOR NRN ZONES BY SUNDAY AS RIDGING BEGINS TO BUILD. WILL LET THE NEXT CREW HAVE A FINAL LOOK AT DEWPOINT PATTERNS AND STRENGTH OF RIDGING BEFORE THAT DECISION IS MADE FOR SUNDAY. .LONG TERM...(MONDAY THROUGH SATURDAY)...MEDIUM TO LONG RANGE MODEL GUIDANCE IS IN GOOD AGREEMENT SHOWING THE SUBTROPICAL RIDGE FIRMLY IN PLACE OVER THE MS RIVER VALLEY ON MONDAY WITH H5 HGTS NEAR 595DM ACROSS NORTHERN MS. UNFORTUNATELY THIS SPELLS A RETURN OF HOT WEATHER FOR THE ARKLAMISS AS AFTERNOON HIGHS CLIMB INTO THE UPPER 90S...AND COMBINED WITH DEW POINTS IN THE MID 70S WILL BE CONDUCIVE TO HEAT INDICES ABOVE 105 DEGREES MONDAY. ISOLATED TO SCATTERED AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS WILL DEVELOP WITH THE BEST COVERAGE ACROSS THE WEST AWAY FROM THE UPPER RIDGE CENTER. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE ACROSS THE WEST WHERE AN AXIS OF 2.25IN+ PW VALUES LIES...ESPECIALLY WITH THE SLOW MOVEMENT EXPECTED OF STORMS THAT DO DEVELOP. VERY LITTLE CHANGE IS PROGGED HEADING INTO TUESDAY AND WEDNESDAY ALTHOUGH THE UPPER RIDGE WILL FLATTEN OUT ACROSS NORTHERN MS/TN IN RESPONSE TO UPPER DISTURBANCES CROSSING THE GREAT LAKES REGION AS WELL AS THE GULF OF MEXICO. SLIGHTLY DRIER AIR WILL WORK ITS WAY ACROSS THE REGION AND BETWEEN THE TWO SHOULD HELP KEEP CONVECTIVE CHANCES ISOLATED FOR MOST AREAS. BEST RAIN CHANCES WILL BE ACROSS THE SOUTH WHERE THE INFLUENCE FROM THE UPPER DISTURBANCE CROSSING THE GULF WILL BE GREATEST. HOT WEATHER WILL CONTINUE...WITH HIGH TEMPERATURES RISING INTO THE UPPER 90S TO NEAR 100...AND HEAT INDICES CLIMBING ABOVE 105 DEGREES BOTH AFTERNOONS. THE HOTTEST CONDITIONS WILL BE ACROSS THE NORTH UNDER THE STRONG RIDGING...AND HEAT INDICES NEAR 110 DEGREES WILL BE POSSIBLE BOTH AFTERNOONS. AT A MINIMUM A HEAT ADVISORY WILL LIKELY BE NEEDED FOR THE WHOLE REGION...WITH EXCESSIVE HEAT WARNING CRITERIA POSSIBLE IN THE NORTH. WILL INCLUDE THESE HOT CONDITIONS IN THE HWO. LONG RANGE MODEL CONSENSUS IS MIXED ON THE EVOLUTION OF THE UPPER RIDGE AND GULF DISTURBANCE LATER IN THE WEEK. THE GFS MAINTAINS STRONG UPPER RIDGING OVER THE ARKLAMISS THROUGH SATURDAY WHILE THE CANADIAN AND ESPECIALLY THE ECMWF WEAKEN THE RIDGE ALLOWING THE UPPER TROUGH TO SHIFT NORTH. THE GFS ENSEMBLE MEAN HINTS AT A WEAKENING UPPER RIDGE SOLUTION AS WELL AND AS SUCH HAVE INCREASED POPS AND DECREASED DAYTIME HIGHS THURS AND FRI TO ACCOUNT FOR INCREASED CLOUDS AND SHOWERS/THUNDERSTORMS EXPECTED IN VICINITY OF THE UPPER TROUGH. THIS SOLUTION WILL ALLOW SOME REPRIEVE FROM THE HEAT LATER IN THE WEEK AND HOPEFULLY BRING THE REGION SOME MUCH NEEDED RAIN. /BK/ && .AVIATION...AREAS OF FOG CAN BE EXPECTED ACROSS THE AREA...LOCALLY LOWERING VSBYS BELOW 2 MILES...BEFORE CLEARING BY 9 AM MOST LOCATIONS. WILL ALSO SEE PATCHES IFR CIGS BELOW 1K FEET THAT WILL LIFT QUICKLY AFTER SUNRISE. SCT-BKN DECKS 2500-4000 FEET WILL BE COMMON TODAY. ISOLATED SHOWERS AND THUNDERSTORMS EARLY TODAY WILL INCREASE IN COVERAGE...BECOMING SCATTERED TO NUMEROUS DURING THE AFTERNOON AND EARLY EVENING BEFORE DIMINISHING AFTER SUNSET. && .PRELIMINARY POINT TEMPS/POPS...
