EVENT...THREAT FOR LOCALLY HEAVY RAINFALL OVER THE NEXT SEVERAL HOURS
.
SATELLITE ANALYSIS AND TRENDS...SQUALL LINE CONTINUES MOVING SEWARD
AT APPROXIMATELY 20KTS THROUGH THE LOWER MISSISSIPPI VALLEY EARLY THIS
MORNING.  CONVECTIVE LINE APPEARS AS THOUGH IT IS BEGINNING TO INTERACT
WITH DEEPER MOISTURE FLUX AND HAVE NOTED AN INCREASE IN THE INTENSITY
OF THE LINE OVER THE LAST FEW HOURS FROM APPROXIMATELY ACP TO JAN.
THE MOST INTENSE PORTION OF THE LINE PASSED JUST SOUTH OF HEZ OVER THE
PAST HOUR AND BASED ON SURFACE REPORTS OUT OF HEZ (1.36" IN THE LAST HOUR)
WOULD THINK THAT AROUND 2.0"/HR RAINFALL RATES HAVE JUST OCCURRED OR ARE
OCCURRING OVER WILKINSON/FRANKLIN/AMITE COUNTY AREA.  FURTHER TO THE SW
A RATHER DISTINCT OVERSHOOTING TOP WAS NOTED WITH THE CONVECTIVE CELL
OVER ST LANDRY PARISH AND WOULD THINK THAT 2.0"/HR RAINFALL RATES ARE
LIKELY IN THIS AREA.
.
HIGHLY DIFFLUENT FLOW BETWEEN SUBTROPICAL JET ALONG THE SUBTROPICAL RIDGE
AXIS AND POLAR JET ASSOCIATED WITH LIFTING GREAT LAKES TROF HELPING TO
AID IN LARGE SCALE FORCING/SYNOPTIC DESTABILIZATION OVER THE REGION.
MESOSCALE BOUNDARY APPEARS AS THOUGH IT IS BECOMING ORIENTED IN A MORE
EAST/WEST DIRECTION ALONG THE WESTERN EDGE IN CNTRL LA.  THIS COMBINED
WITH BEST INSTABILITY AND MOISTURE TRANSPORT INTO THIS GENERAL AREA
COULD RAISE THE THREAT FOR REGENERATING CONVECTION ON THE WESTERN EDGE
WITH SOME DOWNSTREAM TRAINING INTO E/SE LA AND SOUTHERN MS.  WOULD PLACE
HIGHEST THREAT FOR HEAVY RAINFALL ROUGHLY ALONG AN AXIS FROM LFT TO PIB
WITH LOCAL RAINFALL TOTALS OF 1-3" POSSIBLE.  WILL CONTINUE TO MONITOR.
