The radar

The Northeast Alabama radar (KHTX), 37 km from the middle of the area, began a volume at 22:43 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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

Nashville Metro, TN (KBNA), launched 12:00Z, 10.7 hours before the alert went out and 165 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Huntsville, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 19, 3:09 PM CDT, 2 hours 33 minutes earlier.

Area forecast discussion, Apr 19, 3:09 PM CDT, 2 hours 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
309 PM CDT SUN APR 19 2015

.DISCUSSION...
THE LOW PRESSURE SYSTEM AND ASSOCIATED WARM FRONT THAT MOVED THROUGH
OVERNIGHT HAS NOW LIFTING INTO MO/IL AREA WITH THE WARM FRONT
EXTENDING DOWN TO THE SC COAST. DRIER AIR IN THE MID/UPPER LEVELS
CONTINUES TO STREAM INTO THE AREA PER LATEST WV IMAGERY. THIS HAS
HELPED TO CLEAR OUT SOME OF THE HIGH LEVEL CLOUD COVER FROM EARLIER
CONVECTION ALONG THE GULF COAST. HOWEVER...THE LOW LEVEL CU DECK HAS
BEEN SLOW TO CLEAR AND REALLY HAMPERED PEAK HEATING WITH MANY AREAS
STILL IN THE MID TO UPPER 60S. AREAS WEST OF INTERSTATE 65 HAVE SEEN
SOME BETTER CLEARING AND TEMPS HAVE WARMED INTO THE MID 70S. BASED ON
THESE TEMPS CAPE VALUES BETWEEN 1000-15000 J/KG ARE EXPECTED ACROSS
THE TN VALLEY THIS AFTERNOON.

A WEAK SHORTWAVE MOVING INTO THE TN/KY AREA AND A PRE-FRONTAL TROUGH
NOTED ON LATEST SURFACE ANALYSIS NEAR THE MS/AL BORDER WILL BE THE
MAIN DRIVERS OF CONVECTION THIS AFTERNOON. SCATTERED SHOWERS HAVE
DEVELOPED ACROSS NW ALABAMA OUT AHEAD OF THIS BOUNDARY BUT STORMS
HAVE BEEN LIMITED SO FAR. EXPECT AN INCREASE IN INTENSITY AS WE NEAR
PEAK HEATING THIS AFTERNOON AND STORMS BEGIN TO TAP INTO BETTER CAPE
VALUES. ALTHOUGH DEEP LAYER SHEAR REMAINS LIMITED WITH VALUES 30 KTS
OR LESS ACROSS THE TN VALLEY THIS AFTERNOON...THE AMOUNT OF CAPE
AVAILABLE SHOULD ALLOW FOR STORMS WITH MARGINALLY SEVERE HAIL AND
WIND GUSTS. PER THE LATEST HRRR/HIRES GUIDANCE THIS BOUNDARY AND
ASSOCIATED ACTIVITY WILL MOVE FROM WEST TO EAST AND CLEAR THE AREA BY
AROUND 00Z TONIGHT.

THE PARENT UPPER LEVEL LOW LOCATED OVER OK/MO IS FORECAST TO SHIFT
EAST AND LIFT INTO THE OH VALLEY TONIGHT. A STRONGER SURFACE LOW AND
ASSOCIATED COLD FRONT WILL PUSH INTO MS/TN VALLEYS AFTER MIDNIGHT.
FORECAST SOUNDINGS NEAR THE TIME OF THE ARRIVAL OF THE FRONT SHOW A
STRONGER LOW LEVEL JET DEVELOPING WITH SPEEDS ABOVE 50KTS. THIS
COMBINED WITH DEEP LAYER SHEAR ABOVE 40KTS AND HELICITY NEAR 200
M2/S2 WOULD SUPPORT MESOCYCLONE DEVELOPMENT AND POTENTIALLY A FEW
EMBEDDED SUPERCELLS IN THE QLCS LINE. A FEW TORNADOES MAY BE POSSIBLE
WITH THIS LINE. THE TORNADO THREAT SHOULD DECREASE AS THE LINE SHIFTS
EAST INTO NORTH CENTRAL AL AS SHEAR BECOMES MORE UNIDIRECTIONAL.
HOWEVER...WIND GUSTS UP TO 70 MPH AND LARGE HAIL WILL STILL BE
POSSIBLE. VEERING SURFACE WIND PROFILES DUE TO THE TERRAIN OF NE
ALABAMA AND SOUTHERN MIDDLE TENNESSEE MAY ALLOW FOR A BRIEF TORNADO
AS THE LINE BEGINS TO INTERACT WITH THE TOPOGRAPHY.

THE LINE IS FORECAST TO CLEAR THE AREA BETWEEN 09 AND 12Z MONDAY
MORNING. LIGHT SHOWERS BEHIND THE LINE ARE EXPECTED TO CONTINUE
THROUGH EARLY AFTERNOON AS THE UPPER LEVEL TROUGH AXIS ROTATES
MOVES ACROSS THE AREA. QUITE A BIT COOLER TEMPERATURES SPREAD INTO
THE TENNESSEE VALLEY FOR MONDAY NIGHT WITH LOWS DROPPING INTO THE LOW
TO MID 40S. KEPT THE MENTION OF FOG IN THE FORECAST FOR MONDAY NIGHT
AS CLEAR SKIES WILL PROVIDE GOOD RADIATIONAL COOLING.

A BROAD UPPER LEVEL LOW SETUPS UP OVER THE GREAT LAKES THIS WEEK
WITH A FEW DISTURBANCES EXPECTED TO MOVE THROUGH THE AREA. THE GFS
CONTINUES TO SUGGEST RAIN AND THUNDERSTORMS RETURNING TO THE
FORECAST ON WEDNESDAY. HOWEVER...THE ECMWF KEEPS THE FORECAST DRY.
THE GFS ENSEMBLES CONTINUE ARE IN AGREEMENT WITH THE LATEST
OPERATIONAL RUN AND BRING RAIN TO THE AREA FROM WEDNESDAY THROUGH
THURSDAY. A COLD FRONT PUSHING THROUGH THE AREA ON THURSDAY WILL KEEP
THINGS COOL AND DRY ON FRIDAY. RAIN IS THEN EXPECTED TO RETURN BY
NEXT WEEKEND.

STUMPF

&&

.AVIATION...
/ISSUED 1232 PM CDT SUN APR 19 2015/
FOR 18Z TAFS...MVFR CONDITIONS DUE TO CEILINGS ARE EXPECTED THROUGH
THE BEGINNING PORTION OF THE FORECAST UNTIL AROUND 01Z AT BOTH HSV
AND MSL. AN AREA OF SHOWERS/EMBEDDED THUNDERSTORMS WILL MOVE THROUGH
THE AREA BETWEEN THE 19Z-20Z TIME FRAME AND HAVE ACCOUNTED FOR
EXPECTED 5SM SHRA WITH THE SHOWERS. THE NEXT ROUND OF SHOWERS ARE
EXPECTED BETWEEN THE 09Z-10Z TIME FRAME AT HSV AND MSL. HAVE FOR NOW
LEFT OUT THE PREDOMINANT MENTION OF TSRA DUE TO THE SCATTERED/WIDELY
SCATTERED STORMS POSSIBLE. EXPECT THAT THE SHRA SHOULD END BETWEEN
14Z-15Z AT BOTH HSV AND MSL. HAVE CONTINUED WITH MVFR CEILINGS
THROUGH THE END OF THE FORECAST PERIOD.

ACTIVITY. LOCALLY HEAVY RAINFALL MAY ALSO RESULT IN PONDING OF WATER

A FINAL ROUND OF STRONG TO MARGINALLY SEVERE THUNDERSTORMS IS
EXPECTED VERY LATE THIS EVENING AND EARLY MONDAY MORNING AS A
COMPLEX OF STORMS SPREADS EASTWARD FROM THE LOWER MISSISSIPPI VALLEY
REGION. THIS ACTIVITY IS EXPECTED TO GRADUALLY WEAKEN AND DISSIPATE
AS IT SHIFTS EASTWARD INTO THE REGION AFTER MIDNIGHT. HOWEVER...A
THREAT FOR DAMAGING WINDS AND LARGE HAIL WILL STILL EXIST...BUT
MAINLY FOR NORTHWEST ALABAMA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...

THERE IS A SLIGHT CHANCE OF THUNDERSTORMS FROM WEDNESDAY AFTERNOON
THROUGH THURSDAY MORNING...AS A REINFORCING COLD FRONT MOVES
SOUTHWARD THROUGH THE REGION. THE COVERAGE OF STORMS WILL INCREASE
ONCE AGAIN ON FRIDAY NIGHT AND SATURDAY AS A STRONGER STORM SYSTEM
