.MESOSCALE UPDATE...

SQUALL LINE THAT WAS CROSSING MISSISSIPPI OVER THE LAST FEW HOURS HAS BEEN STEADILY LOOSING INTENSITY AND FORM...NOW RESEMBLING A MORE MUDDLED MESS OF TS STRETCHING THE LENGTH OF MISSISSIPPI INTO WESTERN ALABAMA. THE CENTER OF THE SURFACE LOW IS NOW ENTERING WEST CENTRAL MISSISSIPPI WITH THE MAIN COLD FRONT MARKED BY A SHARP T/TD GRADIENT ACROSS WESTERN LOUISIANA. DEWPOINTS AHEAD OF THE COLD FRONT ARE STILL IN THE M/U60S...WITH SOME OBS REPORTING IN AT 70F NEAR THE CENTER OF THE LOW.

CLOSER TO HOME...DEWPOINT GRADIENT EXISTS ACROSS THE CWFA WITH EASTERN ARREARS IN THE M/U50S...WHILE KMSL SITS AT 63F. AS THE HIGH SHEAR/MARGINAL INSTABILITY ENVIRONMENT CONTINUES TO MIGRATE INTO THE CWFA...CONTINUED WEAK CONVECTION IS EXPECTED THROUGH THE MORNING COMMUTE ACROSS THE WEST AND CENTRAL. WHILE AN ISOLATED STRONGER CELL CANNOT BE DISCOUNTED...TRENDS AT THIS POINT AWAY FROM SUCH A SCENARIO.CONSENSUS STILL INDICATES THE POSSIBILITY FOR RENEWED CONVECTION BY MID MORNING AHEAD AND ALONG THE MAIN COLD FRONT AS IT SWEEPS THROUGH THE TENNESSEE VALLEY. SHEAR REMAINS IMPRESSIVE AND FORCING ALONG THE FRONT COULD BE ENOUGH TO SPARK ISOLATED SEVERE THUNDERSTORMS AS THE COLD FRONT TRUCKS THROUGH THE AREA...WITH THE MAIN THREATS DAMAGING WINDS AND BRIEF HEAVY RAIN. WILL CONTINUE TO MONITOR THIS SITUATION AND TAKE A LOOK AT 12Z UPPER AIR DATA AS IT ARRIVES.
