A rare mid summer early morning storm complex moved across Mississippi and produced one tornado and some minor winds damage. The atmosphere this morning had very strong winds for July and this provided enough wind shear to spawn a weak tornado just southeast of Decatur.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 7, 3:28 AM CST, 5 hours 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 428 AM CDT SAT JUL 7 2007 .DISCUSSION...TODAY THROUGH SUNDAY...RADAR THIS MORNING SHOWS A RATHER LARGE AREA OF MODERATE TO OCCASIONALLY HEAVY RAINFALL ACROSS THE NORTHERN PORTION OF THE CWA ALONG A DEFORMATION AXIS...WITH A LINE OF SHOWERS STRETCHING FROM CENTRAL MISSISSIPPI SOUTHWEST INTO EAST CENTRAL LOUISIANA. THIS IS ALL ASSOCIATED WITH A SLOW NORTHEASTWARD MOVING AREA OF LOW PRESSURE CURRENTLY CENTERED OVER NORTH CENTRAL LOUISIANA. WITH A SOUPY AIRMASS ALREADY IN PLACE OVER THE AREA...PRECIPITABLE H2O VALUES ABOVE 2 INCHES AND DEW POINTS IN THE LOWER 70S...COUPLED WITH SOME HEATING...I EXPECT SHOWERS ALONG WITH SOME ISOLATED THUNDERSTORMS TO BASICALLY BE THE CALL OF THE DAY TODAY ACROSS MUCH OF THE FORECAST AREA AS THE LOW CONTINUES ITS NORTHEASTWARD TRACK THROUGH THE DAY. AS A RESULT...I UPPED POPS IN AREAS MAINLY ALONG AND EAST OF INTERSTATE 55 FOR TODAY. IN ADDITION...GIVEN THIS MOISTURE RICH AIRMASS OVER THE AREA...HEAVY RAINFALL IS POSSIBLE WHICH COULD RESULT IN THE PONDING OF WATER ON ROADWAYS AS WELL AS THE OVERFLOWING OF DITCHES AND CULVERTS WHICH COULD CAUSE SOME MINOR FLOODING IN POOR DRAINAGE AREAS. THIS IS HIGHLIGHTED IN THE HWO. IVE PONDERED A FLASH FLOOD WATCH THIS MORNING...BUT WILL HOLD OFF FOR RIGHT NOW GIVEN THAT THE ACTIVITY IS MOVING. HOWEVER...IF HEAVY CONVECTION DEVELOPS AND BEGINS TRAINING OVER AREAS...ONE MAY BE NEEDED. THE RAIN SHOULD BEGIN TO SLOWLY END FROM THE WEST TO EAST THROUGHOUT THE DAY TODAY AS THE LOW EXITS TO THE NORTHEAST. A FEW SHOWERS COULD HANG ON IN THE EAST LATE TONIGHT...BUT THE MAJORITY OF THE AREA WILL BE RAIN FREE BY MIDNIGHT. BEHIND THE LOW...SOME SLIGHTLY DRIER AIR WILL FILTER INTO THE AREA FROM THE NORTHWEST ALLOWING THE AIRMASS TO DRY OUT A BIT CAUSING RAIN CHANCES PLUMMET FOR SUNDAY... WITH ONLY A CHANCE OF RAIN REMAINING IN THE SOUTH WHERE THE AIRMASS WILL REMAIN A LITTLE MORE MOIST. AS FAR AS TEMPERATURES ARE CONCERNED...WITH THE WIDESPREAD RAIN AND CLOUDS OVER THE AREA TODAY FOR MOST OF THE DAY TODAY...I BUMPED HIGHS THIS AFTERNOON DOWN A DEGREE OR TWO IN MOST PLACES. AS FOR LOWS TONIGHT...I BUMPED TEMPERATURES UP IN MANY LOCATIONS...WHICH BRINGS THEM MORE IN LINE WITH THOSE OF THE MET...AS I THINK THE MAV IS OVER PLAYING THIS DRIER AIRMASS AND NOT TO MENTION MOST AREAS STILL HAVING FAIRLY DAMP GROUND CONDITIONS. FOR BASICALLY THE SAME REASONING AS JUST STATED I ALSO BUMPED HIGHS DOWN A FEW DEGREES ON SUNDAY...MAINLY IN THE NORTH...BRINGING THEM MORE IN LINE WITH THOSE OF THE MET...LOWER 90S. /19/ SUNDAY NIGHT THROUGH NEXT SATURDAY...OVERALL...THE MED RANGE/LONG TERM PORTION OF THE FORECAST WILL OFFER LESS CHANCES OF RAIN FOR THE MIDDLE PART OF THE WEEK BEFORE CHANCES INCREASE IN TIME FOR NEXT WEEKEND. FOR MON-WED...THE AREA WILL SEE INCREASING MID LEVEL HEIGHTS AS A DECENT MID/UPPER LEVEL RIDGE BUILDS OFF THE SE COAST AND STRETCHES WESTWARD ACROSS THE GULF. OF THE 3 DAYS...MON LOOKS TO OFFER THE BEST RAIN CHANCES WITH SCT STORMS ACROSS THE CWA. THE MAIN REASON FOR THESE BETTER PRECIP CHANCES WILL BE THAT THERE WILL BE SOME H85 THETA E ADV AS BETTER S/SW LOW LEVEL FLOW DEVELOPS ON THE WESTERN PERIPHERY OF THE STRENGTHENING RIDGE. BY TUE-WED...LOW LEVEL MOISTURE REMAINS QUITE HIGH...BUT THE AIRMASS IS MORE STAGNANT WITH NO REAL MOISTURE ADV REGIME SETTING UP. ALSO DURING TUE-WED...MID LEVEL HEIGHTS WILL BE INCREASING FROM 591 DM TO 594 DM WITH A SMALL MID LEVEL CAP EVIDENT ON FORECAST MODEL SOUNDINGS. EXPECT ONLY ISO/SCT (20-30%) TYPE DIURNAL PRECIP CHANCES. BY THU...MID/UPPER RIDGE LOOKS TO RELAX AS A MORE PRONOUNCED TROUGH DROPS OUT OF THE S PLAINS WHICH WILL BE THE BEGINNING OF A FAIRLY SUBSTANTIAL E TROUGH. THIS WILL PLACE THE CWA IN A GENERAL NW FLOW PATTERN WITH THE SEMBLANCE OF A FRONTAL BOUNDARY IN THE AREA BETWEEN FRI-SUN. DETAILS OF COURSE WILL DRIVE THE DAY-TO-DAY WX...BUT SAID PATTERN/SET UP SUGGESTS THE POTENTIAL FOR A FEW CONVECTIVE EVENTS SOME OF WHICH WILL LIKELY CONTAIN SVR STORMS. WITH NEARLY ALL EXTENDED GUID SUGGESTING SUCH A SCENARIO...HAVE OPTED TO START TWEAKING POPS UPWARD FOR FRI-SAT...MAINLY N HALF. WILL NOT MENTION ANY SVR POTENTIAL IN HWO AT THIS POINT...WILL WAIT FOR CONFIDENCE TO INCREASE OVER THE NEXT COUPLE OF DAYS AND MORE MODEL RUNS. AS FOR TEMPS...WITH INCREASING S FLOW AND GOOD SFC MOISTURE LINGERING...WILL KEEP MORNING LOWS GENERALLY IN THE LOWER/MIDDLE 70S. FOR THE MOST PART...GUID OFFERS THOSE VALUES WITH THE EXCEPTION BEING FOR MON-TUE. DURING THE FIRST PART OF THE WEEK...SOME SITES ARE IN THE UPPER 60S AND HAVE TWEAKED UPWARD. AS FOR HIGHS...GUID INCREASES THE AREA TO THE LOWER 90S FOR THE FIRST HALF OF THE WEEK. HAVE ACCEPTED THOSE VALUES AS THE AREA WILL HAVE TO EVAP WET SOILS BEFORE CRANKING UP THE HEAT. FOR THE SECOND HALF OF THE WEEK INTO SAT...GUID STARTS TO COME DOWN ON TEMPS. NOT SURE THAT WILL BE THE CASE A THE CWA WILL BE AHEAD OF A SFC FRONT WHICH TYPICALLY OFFERS THE WARMEST DAYS BEFORE THE FRONT WOULD PASS. LOW LEVEL FLOW ALSO VEERS AND BECOME MORE WESTERLY WHICH ALWAYS MEANS AT LEAST MID 90S THIS TIME OF YEAR. DUE TO THIS...HAVE INCREASED HIGHS CLOSER TO CLIMO AND ENSEMBLE MEANS...STILL A BIT CONSERVATIVE...BUT SHOULD BE IN THE RIGHT DIRECTION. /CME/ && .AVIATION...SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE OVER MUCH OF THE AREA THROUGHOUT THE DAY TODAY. THIS ACTIVITY WILL CAUSE MVFR CONDITIONS AT MOST TAF SITES THROUGH THE DAY...WITH LOCALLY IFR/LIFR CONDITIONS POSSIBLE WHERE HEAVIER CONVECTION OCCURS. CONDITIONS WILL BEGIN TO IMPROVE LATER THIS AFTERNOON BEGINNING IN THE WEST AND CONTINUING THROUGH THE EAST AS THE EVENING PROGRESSES. HOWEVER...MVFR TO LOCALLY IFR CONDITIONS WILL AGAIN BE POSSIBLE AS A RESULT OF FOG LATE TONIGHT AND INTO EARLY SUNDAY MORNING. /19/ && .PRELIMINARY POINT TEMPS/POPS...

NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS. .DAY ONE...TODAY AND TONIGHT HEAVY RAINFALL WILL BE POSSIBLE FOR THE ENTIRE OUTLOOK AREA TODAY AND COULD LINGER INTO TONIGHT ACROSS EAST MISSISSIPPI. CONDITIONS ALONG AND NORTH OF INTERSTATE 20 WILL BE MORE FAVORABLE FOR FREQUENT DOWNPOURS. THE ATMOSPHERE OVER THE ARKLAMISS REGION REMAINS QUITE MOIST. A SURGE OF TROPICAL MOISTURE WILL MOVE INTO THE AREA TODAY AS AN UPPER LEVEL DISTURBANCE...CURRENTLY OVER NORTH CENTRAL LOUISIANA...CONTINUES TO DRIFT TO THE NORTHEAST THROUGH THE DAY. PERIODS OF HEAVY RAINFALL WILL BE LIKELY ACROSS THE AREA AS THE DISTURBANCE INTERACTS WITH THE WARM MOIST AND UNSTABLE AIRMASS IN PLACE OVER THE OUTLOOK AREA. AS A RESULT...THE PONDING OF WATER ON ROADWAYS WILL BE LIKELY...AS WELL AS OVERFLOWING DITCHES AND CULVERTS WHICH COULD CAUSE MINOR FLOODING IN POOR DRAINAGE AREAS. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW. .SPOTTER CALL TO ACTION STATEMENT... THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER OPERATIONS IS NOT ANTICIPATED THROUGH NEXT FRIDAY.
