Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Slidell Radar S, LA (KSIL), launched 12:00Z, 8.4 hours before the alert went out and 189 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 20, 12:15 PM CDT, 3 hours 11 minutes before

AREA FORECAST DISCUSSION...UPDATE TO AVIATION
NATIONAL WEATHER SERVICE MOBILE AL 1215 PM CDT MON JUL 20 2015

.UPDATE TO SHORT TERM...CURRENT PACKAGE GENERALLY ON TRACK...WITH
HEAT INDICES AT 11 AM RANGING FROM THE UPPER 90S OVER SOUTHEASTERN
PORTIONS OF THE FA...TO 101 TO 106 ACROSS THE WEST-NORTHWESTERN HALF
OF THE FA. TEMPS A DEGREE OR TWO BELOW FORECAST...BUT TD VALUES ARE
A DEGREE OR TWO ABOVE...LEADING TO HEAT INDICES CLOSE TO FORECAST.
NO UPDATES PLANNED.

HAVE BEEN SEEING A FEW SHRA FORMING OVER A WEAK BOUNDARY/POOL OF
MOISTURE STRETCHING OVER THE NORTHEASTERN PORTION OF THE FA. AM
ALSO SEEING A FEW SHRA FORM OVER THE SOUTHWESTERN QUARTER OF THE
FA...WITH GREATER INSTABILITY THESE AREAS THE CAUSE. WITH DRY AIR
ABOVE THE SURFACE SHOWING ON MOST OF THE NEIGHBORING UPPER AIR
SITES(KJAN/KLIX/KBMX)...A FEW STORMS THAT FORM TODAY WILL BE STRONG
TO SEVERE...WITH DAMAGING WINDS THE PROBLEM.

&&

.AVIATION... 18Z ISSUANCE...GENERAL VFR CONDITIONS EXPECTED ACROSS
THE AREA THROUGH THE FORECAST. DROPS TO MVFR LEVEL CIGS/VISBYS
LIKELY IN SHRA/TSRA FORMING ACROSS THE AREA ATTM. LOOKING AT
SURROUNDING VWPS...GENERAL DIRECTION OF MOVEMENT OF SHRA/TSRA AFTER
FORMING IS EXPECTED TO RANGE FROM SSE OVER EASTERN PORTIONS OF THE
FA TO SSW ACROSS WESTERN PORTIONS.

/16

&&
.PREVIOUS(FROM 317 AM)...

.SHORT TERM (TODAY THROUGH WEDNESDAY NIGHT)...FOR TODAY AND
TONIGHT...SAME STORY DIFFERENT DAY. UPPER RIDGING CONTINUES OVER THE
REGION...ALTHOUGH JUST SLIGHTLY WEAKER THAN PREVIOUS 48 HOURS. SFC
RIDGE CONTINUES OVER EASTERN GULF OF MEXICO...MAINTAINING THE MOIST
WEST TO SOUTHWEST LOLVL WIND FLOW THROUGH TONIGHT. THIS FLOW WILL
KEEP DEWPOINTS IN THE MID TO UPPER 70S ACROSS THE REGION THROUGH
TONIGHT (POSSIBLY EVEN IN THE LOWER 80S NEAR THE COAST THIS
AFTERNOON). SUBSIDENCE FROM THE UPPER RIDGING AND THE HIGH DEWPOINTS
WILL AGAIN RESULT IN EXCESSIVE HEAT ACROSS THE AREA TODAY. HIGH
TEMPERATURES WILL CLIMB INTO THE LOWER 90S NEAR THE COAST AND MID TO
UPPER 90S OVER INTERIOR ZONES THIS AFTERNOON. THROW IN THE EXPECTED
RELATIVE HUMIDITY VALUES...AND HEAT INDICES WILL AGAIN EASILY RANGE
FROM AROUND 108 TO NEAR 112 DEGREES ACROSS MOST OF THE FCST AREA
AGAIN TODAY. THE HEAT ADVISORY REMAINS IN EFFECT FOR TODAY...NOON TO
7 PM. SOME REMAINING CONVECTION OUT OVER THE MARINE AREA EARLY THIS
MORNING...BUT PCPN HAS ENDED OVER LAND ZONES. BY LATE MORNING AND
THEN ESPECIALLY THIS AFTERNOON INTO THE EARLY EVENING HOURS...SHOULD
SEE MORE SCATTERED SHOWERS AND THUNDERSTORMS DEVELOP OVER THE
INTERIOR AND DROP SOUTH ACROSS THE FCST AREA ON THE EASTERN PERIPHERY
OF THE UPPER RIDGE. AMPLE INSTABILITY WITH THE HEAT AND MOISTURE IN
PLACE OVER THE REGION...COMBINED WITH SEVERAL WEAK IMPULSES OF
ENERGY ALOFT...AS WELL AS LEFT OVER OUTFLOW BOUNDARIES AND SEA BREEZE
INTERACTIONS...COULD RESULT IN SOME OF THE STORMS TODAY BECOMING
STRONG TO BRIEFLY SEVERE. CONTINUED QUITE WARM AND MUGGY TONIGHT WITH
OVERNIGHT LOW TEMPERATURES RANGING FROM THE MID 70S INLAND TO NEAR 80
AT THE COAST. 12/DS

FOR TUESDAY THROUGH WEDNESDAY NIGHT...THE UPPER RIDGE OVER THE REGION
WEAKENS SOMEWHAT AND ALSO SHIFTS A BIT SOUTHWARD AS AN UPPER TROF
MOVES ACROSS THE INTERIOR EASTERN STATES. WHILE A SURFACE RIDGE
REMAINS OVER THE NORTHERN/CENTRAL GULF...A WEAK SURFACE TROF ALSO
PERSISTS OVER THE INTERIOR PORTION OF THE FORECAST AREA...AIDED
SOMEWHAT BY A SURFACE TROF OVER THE EAST COASTAL STATES. HIGHS ON
TUESDAY WILL RANGE FROM THE MID/UPPER 90S INLAND TO LOWER 90S NEAR
THE COAST WITH SLIGHTLY LOWER VALUES OVERALL ON WEDNESDAY WITH THE
WEAKENING SUBSIDENCE AND WILL HAVE MID 90S FOR THE AREA WITH LOWER
90S AT THE COAST. AFTERNOON HEAT INDEX VALUES LOOK TO BE NEAR OR
SLIGHTLY ABOVE HEAT ADVISORY CRITERIA OF 108 FOR MOST OF THE AREA ON
TUESDAY AND HAVE OPTED TO INCLUDE THE ENTIRE AREA IN A HEAT ADVISORY
FOR TUESDAY AFTERNOON. DESPITE SOMEWHAT LOWER HIGHS ON
WEDNESDAY...SOME LOCATIONS STILL REACH HEAT ADVISORY CRITERIA AND YET
ANOTHER ADVISORY MAY BE REQUIRED. OVERNIGHT LOWS WILL RANGE FROM THE
MID 70S INLAND TO NEAR 80 AT THE COAST. WITH THE WEAK SURFACE TROF IN
PLACE ALONG WITH DAYTIME HEATING AND AMPLE DEEP LAYER MOISTURE WITH
PRECIPITABLE WATER VALUES NEAR 2.0 INCHES...EXPECT SCATTERED
CONVECTION TO DEVELOP EACH AFTERNOON AND LINGER INTO THE EVENING
HOURS. DESPITE WET BULB ZERO VALUES MOSTLY 12.5-13.5 KFT...SURFACE
BASED CAPES OF 2500-3000 J/KG WILL BE PRESENT EACH
AFTERNOON...POSSIBLY HIGHER...AND MODEL SOUNDINGS SHOW A FAIRLY DEEP
LAYER OF DRY AIR FROM 700-400 MB ON TUESDAY WITH SOME IMPROVEMENT ON
WEDNESDAY. WILL CONTINUE TO MENTION THE POTENTIAL FOR A FEW STRONG
TO SEVERE STORMS EACH DAY IN THE HAZARDOUS WEATHER OUTLOOK. /29

.LONG TERM (THURSDAY THROUGH SUNDAY)...AN UPPER TROF REMAINS OFF THE
EAST COAST THROUGH MUCH OF THE PERIOD WHILE UPPER RIDGING AMPLIFIES
OVER THE PLAINS. A SURFACE TROF MEANDERS OVER THE FORECAST AREA
THROUGH THE PERIOD AND WITH AMPLE DEEP LAYER MOISTURE AND A SERIES OF
SHORTWAVES LIKELY AFFECTING THE REGION...EXPECT SCATTERED CONVECTION
EACH DAY WHICH LINGERS OVERNIGHT WITH THE CONTINUED POTENTIAL FOR
STRONG STORMS. DAYTIME HIGHS WILL BE IN THE MID 90S EXCEPT FOR LOWER
90S NEAR THE COAST AND OVERNIGHT LOWS WILL RANGE FROM THE MID 70S
INLAND TO NEAR 80 AT THE COAST. /29

&&

.MARINE...A BROAD SFC RIDGE OF HIGH PRESSURE OVER THE EASTERN GULF
OF MEXICO WILL CONTINUE THROUGH LATE WEEK. THIS PATTERN WILL
MAINTAIN THE LIGHT TO MODERATE WEST TO SOUTHWESTERLY FLOW OVER THE
MARINE AREA THROUGH THE WEEK. SCATTERED SHOWERS AND THUNDERSTORMS
WILL BE POSSIBLE EACH DAY. A FEW STORMS COULD BE STRONG AT TIMES
WITH GUSTY WINDS...FREQUENT LIGHTNING...AND LOCALLY HIGHER WAVES.
