What happened

The episode as NWS SHV wrote it up.

A strong cold front moved southeast into the region during the early morning hours of March 5th. These storms encountered a weakly unstable airmass but the upper level low pressure system in association with the front...allowed for steep mid level lapse rates. As a result, these storms produced mostly small sub-severe hail across portions of northern Louisiana.

What forecasters said that day

.DISCUSSION...
COLD FRONT CONTINUES TO MAKES STEADY PROGRESS SE ACROSS THE REGION
THIS MORNING...AND EXTENDS FROM JUST SE OF A LIT...TO
MAGNOLIA...TO BLANCHARD...RFI...JSO...AND CLL LINE AS OF 10Z...PER
SFC OBS AND RADAR IMAGERY. CONVECTION HAS NOW BECOME PRIMARILY POST-
FRONTAL ACROSS NE TX/SW AR/EXTREME SE OK...ALTHOUGH THIS SHOULD
CHANGE LATER THIS MORNING AS UPPER LEVEL DIFFLUENCE/PVA AHEAD OF THE
POSITIVE TILT TROUGH EXTENDING ACROSS THE OK/TX PANHANDLES INTO W
TX...SPREADS E INTO A DEEPER AXIS OF MOISTURE...AND WEAKENS THE
CAP/CIN IN PLACE. HAVE BASED HIGHEST POPS ACROSS THE ERN HALF OF
THE AREA THIS MORNING...WITH MAX TEMPS LIKELY OCCURRING EARLY THIS
MORNING AT/PRIOR TO THE FROPA BEFORE THEY BEGIN TO FALL DURING THE
DAY....WITH LITTLE RECOVERY EXPECTED DURING THE AFTERNOON ONCE THE
PRECIP SHIELD DIMINISHES FROM W TO E. NOT EXPECTING ANY
ADDITIONAL SVR WEATHER TODAY AS SFC BASED INSTABILITY REMAINS
WEAK...AND FRONTAL CONVERGENCE WEAKENS LATER THIS MORNING AS PRE-
FRONTAL WINDS VEER MORE WSW AHEAD OF THE BNDRY AS IT PUSHES E
ACROSS SCNTRL AR/NCNTRL LA AND EXITS THE REGION BY MIDDAY. GIVEN
STEEP LAPSE RATES OF 7-7.5 C/KM IN THE 700-500MB LYR...CAN/T RULE
OUT EMBEDDED THUNDER WITH SMALL HAIL IN THE STRONGER STORMS GIVEN
LOW WET BULB ZERO HEIGHTS BETWEEN 8-10KFT.

DID TRANSITION POPS FOR THE AFTERNOON TO REFLECT A QUICKER
DIMINISHING TREND FROM W TO E...BUT DID NOT REMOVE THEM COMPLETELY
AS ISOLATED/WIDELY SCT SHRA AND ELEVATED -TSRA WILL BE POSSIBLE
ALONG THE PRIMARY UPPER TROUGH AXIS...AS IS THE CASE NOW ACROSS
WCNTRL TX BETWEEN SJT AND SPS...WITH THE TROUGH AXIS MOVES INTO
SCNTRL AR/NCNTRL LA BY EARLY EVENING. ENOUGH DRY AIR ADVECTING SE
BEHIND THE FRONT THIS AFTERNOON SHOULD BE DEEP ENOUGH FOR ANY
ELEVATED -SHRA TO EVAPORATE BEFORE REACHING THE GROUND ACROSS THE
ERN ZONES THIS EVENING...THUS HAVE REMOVED POPS FOR THE REMAINDER
OF THE AREA.

WILL ALSO HAVE TO CONTEND WITH A TIGHT PRESSURE GRADIENT BEHIND
THE FROPA THIS MORNING/AFTERNOON...SUCH THAT WIND GUSTS COULD TOP
25KTS ACROSS MUCH OF E TX/EXTREME SW AR/NW LA. HAVE ERRED ON THE
SIDE OF CAUTION GIVEN THE WEEKEND...AND A VARIETY OF OUTDOOR
ACTIVITIES SCHEDULED...AND POSTED A LAKE WIND ADVISORY FOR EXTREME
SE OK/MUCH OF E TX/EXTREME SW AR/NW LA THROUGH 00Z SUNDAY. THE
PRESSURE GRADIENT SHOULD BEGIN TO RELAX BY EARLY EVENING...AS A
SFC RIDGE BUILDS S INTO THE AREA TONIGHT/SUNDAY. GIVEN THE
WEAKENING GRADIENT...AND CLEARING SKY...TEMPS WILL NEAR/FALL
SLIGHTLY BELOW FREEZING LATE TONIGHT...ESPECIALLY IN THE PROTECTED
AREAS OF SE OK/SW AR.

ELEVATED MOISTURE WILL INCREASE AREAWIDE SUNDAY NIGHT FROM THE
WNW...WHICH WILL THICKEN WITH TIME SUCH THAT MIN TEMPS MAY BE HELD
UP A FEW DEGREES HIGHER THAN FORECAST MIN TEMPS TONIGHT. TEMPS
WILL BEGIN TO MODERATE BACK ABOVE SEASONAL NORMS BY MONDAY NIGHT
AS A SRLY LLJ DEVELOPS ACROSS THE SRN PLAINS...IN RESPONSE TO THE
DEVELOPING CYCLOGENESIS OVER NW TX...AHEAD OF THE NEXT UPPER
TROUGH THAT WILL DIG SE THROUGH THE GREAT BASIN AND ROCKIES
MONDAY/MONDAY NIGHT. HAVE SPED UP SLIGHT CHANCE POPS MONDAY NIGHT
ACROSS E TX/SE OK...GIVEN THE INCREASING ISENTROPIC FORCING ALONG
THE LLJ AXIS. THE TROUGH WILL BEGIN TO AMPLIFY TUESDAY AS IT
EMERGES INTO THE CNTRL/SRN PLAINS...WITH LARGE SCALE FORCING
INCREASING TUESDAY AFTERNOON ACROSS CNTRL TX/OK...WITH THE INITIAL
SHORTWAVE EJECTING NE INTO THE MIDWEST TUESDAY NIGHT. THE MEDIUM
RANGE PROGS ARE NOW INDICATING CONSIDERABLE DRY-SLOTTING BENEATH
THE TROUGH AS THE FIRST SHORTWAVE EJECTS NE...RESULTING IN MUCH
LOWER QPF/S ACROSS E TX/SE OK THAN WHAT WAS INDICATED YESTERDAY.
HOWEVER...STRONG DEEP LYR SHEAR...MARGINAL INSTABILITY...AND
STEEP LAPSE RATES IN PLACE BENEATH THE TROUGH/AHEAD OF THE
ATTENDANT COLD FRONT MAY YIELD A SVR THREAT AREAWIDE TUESDAY
NIGHT/EARLY WEDNESDAY...ESPECIALLY AS THE EJECTING SHORTWAVE TAKES
ON A MORE NEGATIVE TILT AS IT ENCOUNTERS DEEPER LOW LEVEL MOISTURE
FROM SE TX INTO NCNTRL LA/MS. HAVE RAISED POPS TO LIKELY N OF I-20
WHERE THE BEST OVERALL FORCING LIES...BUT HAVE RETAINED HIGH
CHANCE POPS ELSEWHERE AS DEEP LYR MOISTURE REMAINS IN QUESTION.

MUCH COOLER AND DRIER AIR WILL FOLLOW THIS NEXT FROPA...WITH
SEASONAL TEMPS AGAIN RETURNING TO THE REGION THROUGHOUT THE
REMAINDER OF THE EXTENDED.
