DISCUSSION
(TODAY THROUGH MONDAY)
ISSUED AT 257 AM CDT TUE MAY 6 2025
THE MAJORITY OF TODAY LOOKS DRY AND MILD WITH TEMPERATURES IN THE
MID 70S IN BETWEEN SYSTEMS. THE RETURN OF SHOWERS AND
THUNDERSTORMS IS ON TAP TONIGHT AS AN OCCLUDED SURFACE LOW SKIRTS
ACROSS THE SOUTHERN GULF COAST STATES. WE ARE ON THE WARM FRONTAL
SIDE, WHICH WILL LEAD TO A LONG PERIOD OF WAA SHOWERS AND THE
OCCASIONAL THUNDERSTORM STARTING TONIGHT, CONTINUING THROUGH AT
LEAST TOMORROW EVENING. THE MAJORITY OF THE QPF FOR THIS PERIOD WILL
FALL BETWEEN TODAY AND TOMORROW. MOST LIKELY AMOUNTS RANGE FROM 1
TO 2 INCHES OVER NORTH MISSISSIPPI, DRASTICALLY DECREASING WITH A
TIGHT GRADIENT AS YOU MOVE NORTH TO THE TN/MS STATE LINE.
REASONABLE WORST CASE SCENARIO FOR QPF (10% CHANCE OF THIS
OCCURRING) SHOWS ABOUT 3 INCHES FOR OUR SOUTHERNMOST MISSISSIPPI
COUNTIES THROUGH THE MIDWEEK RAINFALL.
WILL NOTE THAT EVEN AFTER THE BULK OF THE RAINFALL OCCURS
OVERNIGHT TONIGHT AND TOMORROW, THE FRONT WILL STALL ALONG THE
GULF COAST AND CONTINUE TO BRING INTERMITTENT WAVES OF RAIN TO OUR
SOUTHERN ZONES. IT'S FORTUNATE THAT WE'RE NOT WORKING WITH MUCH
OF ANY INSTABILITY AND THERE IS ALMOST NO KINEMATIC SUPPORT GIVEN
OUR POSITIONING WITH RESPECT TO THE SURFACE LOW AND FRONT. EXPECT
A FEW DAYS OF UNSETTLED WEATHER WITH BELOW NORMAL TEMPERATURES IN
THE MID 70S.
THE PATTERN CONTINUES TO BE A BIT OF A MESS THROUGH THE WEEKEND.
AFTER THE SURFACE LOW MAKES ITS WAY OVER TO THE FL PANHANDLE ON
SATURDAY, IT WILL ALSO DEEPEN AND EVENTUALLY OCCLUDE. AN INVERTED
TROUGH LOOKS TO EXTEND UPWARD INTO THE MID-SOUTH AS THIS HAPPENS,
WHICH WILL KEEP RAIN CHANCES IN THE 30-40% RANGE DAILY FOR OUR
SOUTHEASTERN ZONES WELL INTO NEXT WEEK. OVERALL AN UNSETTLED BUT
NOT IMPACTFUL WEATHER PATTERN FOR THIS FORECAST PERIOD.

SKIES STILL CONTAIN SOME VFR CIGS AROUND 10 KFT ACROSS FAR WEST
TN AND EAST AR THAT HAVE STEADILY DECREASED IN COVERAGE. SOME OF
THESE CLOUDS COULD SPREAD OVER INTO MKL AND MEM WHILE REMAINING
OVER JBR THROUGH THE NIGHT. LIGHT WINDS WILL PREVAIL INTO TOMORROW
MORNING WHERE SOUTHEASTERLIES WILL BEGIN TO TAKE HOLD THROUGH THE
END OF THE PERIOD AT ALL TERMINALS. SOME RAIN IS POSSIBLE
BEGINNING AFTER 00Z AS A NEW SYSTEM ENTERS THE REGION. DROPS TO
MVFR ASSOCIATED WITH SHOWERS COULD OCCUR AT ALL TERMINALS, BUT
FORECAST CONFIDENCE IS STILL LOW WITH RESPECT TO COVERAGE. AFTER
06Z AT MEM, PREVAILING -SHRA AND MVFR CIGS/VISBYS ARE ANTICIPATED.
