MESOSCALE PRECIPITATION DISCUSSION 0081
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
925 PM EDT SAT APR 04 2026
AREAS AFFECTED...SOUTHERN LA AND SOUTH-CENTRAL MS
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE
VALID 050125Z - 050500Z
SUMMARY...NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS
MUCH OF SOUTHERN LOUISIANA INTO SOUTHERN MISSISSIPPI THROUGH THE
REMAINDER OF THE EVENING HOURS, INCLUDING EXTREME SOUTHEAST TEXAS.
AREAS WITH PERSISTENT TRAINING CELLS COULD GET 1 INCH/30 MINUTE
RAINFALL RATES, WHICH COULD RESULT IN A FEW INSTANCES OF FLOODING
THROUGH MIDNIGHT.
DISCUSSION...REGIONAL DOPPLER RADARS AND VISIBLE SATELLITE IMAGERY
ARE INDICATING WIDESPREAD CONVECTION ALONG AND AHEAD OF AN
APPROACHING COLD FRONT. THERE ARE SEVERAL MULTI-CELL CLUSTERS THAT
HAVE DEVELOPED AHEAD OF THE MAIN SWATH OF CONVECTION ASSOCIATED
WITH THE COLD FRONT, AND THESE ARE ALIGNED IN THE GENERAL LOW
LEVEL SSW WINDS AND HAVE BEEN TRAINING OVER THE PAST FEW HOURS.
MANY LOCATIONS ACROSS CENTRAL LOUISIANA AND CENTRAL MISSISSIPPI
HAVE ALREADY PICKED UP 1-2 INCHES OF RAIN OVER THE PAST 6 HOURS,
AND LOCALLY HIGHER, THEREFORE MAKING THE SOILS MORE SATURATED AND
SUSCEPTIBLE TO POTENTIAL FLOODING ISSUES.
RECENT RUNS OF THE RRFS AND HRRR ARE INDICATING THE POTENTIAL FOR
SCATTERED QPF MAXIMA ON THE ORDER OF 1-3 INCHES THROUGH 5Z, WITH
MUCH OF THIS LIKELY OCCURRING WITHIN A 2-3 HOUR TIME PERIOD FOR
ANY GIVEN LOCATION. THIS ACTIVITY SHOULD GENERALLY DIMINISH IN
INTENSITY GOING INTO THE OVERNIGHT HOURS AS INSTABILITY DECREASES.
