AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 312 PM CDT SAT JUN 30 2007 .DISCUSSION... ANOTHER AFTERNOON WITH MODERATE ATMOSPHERIC INSTABILITY AND WEAK SHEAR. EXPECT ISOLATED PULSE SEVERE THREAT TO CONTINUE THROUGH LATE AFTERNOON...MAINLY OVER NORTHERN MS. ONCE SURFACE TEMPS BEGIN TO WANE IN THE LOWER SUN ANGLES... EXPECT STORM COVERAGE TO DECREASE EARLY IN THE EVENING. SEVERE THREAT REMAINS MORE FOCUSED WELL WEST OF THE MIDSOUTH...AHEAD OF A SURFACE LOW PRESSURE SYSTEM OVER NORTHERN OK. THIS SURFACE LOW PRESSURE SHOULD NOT AFFECT THE MIDSOUTH AND SHOULD REMAIN NEAR ITS CURRENT POSITION. PROSPECTS FOR A NEAR TERM FRONTAL PASSAGE INTO THE MIDSOUTH APPEAR SLIM...GIVEN THE STRENGTH OF THE OK SURFACE LOW AND THE UPPER LEVEL RIDGE OVER THE SOUTHEAST. GOES WATER VAPOR IMAGERY SHOWED A BROAD UPPER LOW JUST WEST OF THE YUCATAN PENINSULA...LIFTING NORTHEAST. GFS APPEARS TO NOT HAVE INITIALIZED THIS LOW VERY WELL. SUSPECT THIS FEATURE WILL SUFFICIENTLY WEAKEN THE UPPER RIDGE TOMORROW TO RESULT IN SCATTERED STORMS OVER THE MIDSOUTH AND MUCH OF THE SOUTHEAST. THIS APPEARS TO ALREADY BE OCCURRING TODAY...WITH ENERGY EJECTING NORTH FROM THE BROAD UPPER LOW... INTO THE LOWER MS RIVER VALLEY. THE GFS IS STILL INTENT ON DROPPING A COLD FRONT INTO THE MIDSOUTH TOWARD THE END OF NEXT WEEK. ECMWF MODEL CONCURS TO A SMALL EXTENT. IN ANY CASE...EXPECT THE IMPACT OF A FRONTAL PASSAGE TO BE LIMITED TO A SLIGHT BUMP IN RAIN CHANCES...AS TEMPS REMAIN NEAR SEASONAL NORMS. OVERALL...TYPICAL EARLY TO MID SUMMER WEATHER FOR THE MIDSOUTH. PWB && .PRELIMINARY POINT TEMPS/POPS...
