The radar

The Maxwell AFB radar (KMXX), 83 km from the middle of the area, began a volume at 20:11 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

Birmingham, AL (KBMX), launched 12:00Z, 8.2 hours before the alert went out and 91 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 Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 10, 12:46 PM CDT, 2 hours 25 minutes earlier.

Area forecast discussion, Apr 10, 12:46 PM CDT, 2 hours 25 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1246 PM CDT FRI APR 10 2015

.UPDATE...
AVIATION DISCUSSION.

&&

.DISCUSSION...

COLD FRONT STRETCHES ACROSS NORTHWEST CENTRAL ALABAMA THIS
MORNING...WITH A LINE OF BROKEN SHOWERS JUST AHEAD OF THE BOUNDARY
MOVING ACROSS THE I-59 CORRIDOR. SOUTHERN END OF THIS LINE IN
MISSISSIPPI DOES HAVE EMBEDDED THUNDERSTORMS IN IT. AHEAD OF THE
FRONT...SHOWERS AND THUNDERSTORMS ALONG A OUTFLOW BOUNDARY ARE
CROSSING THE I-85 CORRIDOR. UPDATED POP AND WEATHER GRIDS REFLECT
ADJUSTMENTS MADE ON LATEST RADAR TRENDS.

COLD FRONT WILL SLOWLY MOVE SOUTHEASTWARD THROUGH THE DAY...WITH
RAIN ENDING FROM NORTHWEST TO SOUTHEAST. INCREASES IN INSTABILITY
AHEAD OF THE COLD FRONT WILL DEPEND ON BREAKS IN THE CLOUD
COVER. IN PLACES THIS OCCURS...1000-1500J/KG IS POSSIBLE. A WEAK
SURFACE LOW MOVING ALONG THE FRONT COULD PROVIDE SOME ENHANCEMENT
TO STORM STRENGTH THIS AFTERNOON. HOWEVER...FROM CURRENT
VALUES...WIND SHEAR DOES GRADUALLY DECREASE AND REMAINS MAXIMIZED
ALONG THE FRONT AT AROUND 20KTS. WILL HAVE TO WATCH ACTIVITY THIS
AFTERNOON AS THERE COULD BE AN UPTICK IN STORM STRENGTH...BUT
EXPECT STORMS TO REMAIN BELOW SEVERE LIMITS.

14

&&

.AVIATION...
18Z TAF DISCUSSION.

A COUPLE BANDS OF SHOWERS AND THUNDERSTORMS MOVING ACROSS CENTRAL
ALABAMA AHEAD OF A COLD FRONT. MGM AND TOI WILL BE THE MAIN
LOCATIONS IMPACTED BY LIGHTNING AND GUSTY WINDS. EXPECT CIGS AND VIS
TO BRIEFLY DROP WITH HEAVIER RAINFALL AS WELL. LIGHT RAIN AND/OR
SHOWERS COULD BE POSSIBLE AT BHM...TCL AND EET DUE TO CONVECTION
TRACKING TO THE SOUTH OF THOSE TERMINALS.

FRONT WILL CONTINUE TO PUSH SOUTHWARD...WITH A WIND SHIFT TO THE
NORTHWEST AND IMPROVING CIGS ACROSS THE NORTH THIS AFTERNOON. DO NOT
EXPECT DRIER AIR TO MAKE IT AS FAR SOUTH AS MGM AND TOI
TONIGHT...AND REDUCED VIS AND CIGS ARE POSSIBLE AS FOG FORMS. THESE
CONDITIONS WILL IMPROVE SATURDAY MORNING...WITH WINDS FROM NORTHEAST
INCREASING TO 8-11KTS AREAWIDE.

14

&&

.PREV DISCUSSION...
/ISSUED 643 AM CDT FRI APR 10 2015/

THUNDERSTORMS HAVE IMPACTED THE NORTHWEST COUNTIES OVERNIGHT...BUT
NOTHING SEVERE. THE ACTIVITY HAS BEEN LESS ORGANIZED THAN EXPECTED
AS CLUSTERS OF SHOWERS AND THUNDERSTORMS HAVE DEVELOPED WELL
AHEAD OF THE COLD FRONT. AT 3 AM THE COLD FRONT WAS LOCATED JUST
EAST OF MEMPHIS. STILL EXPECT THE AREA OF CONVECTION WILL BECOME
MORE LINEAR DURING THE MORNING HOURS AS THE MAIN FORCING SHIFTS
NORTHWARD CLOSER TO THE FRONTAL BOUNDARY. WITH THE LOW LEVEL
INFLOW DECREASING AND VEERING...DO NOT EXPECT MUCH INCREASE IN
STORM INTENSITY DURING THE DAY. AS THE FRONT PUSHES SOUTH OF I-20
THIS AFTERNOON...THERE MIGHT BE SOME RE-INTENSIFICATION DUE TO
DAYTIME HEATING. A ISOLATED SEVERE STORM IS NOT OUT OF THE REALM
OF POSSIBILITY FOR AREAS ALONG AND SOUTH OF I-85 LATER TODAY...BUT
CONFIDENCE AND ISOLATED NATURE OF STORMS DOES NOT WARRANT AN
INCLUSION IN ANY OF THE HAZARDOUS WEATHER PRODUCTS.

THE ACTIVITY WILL SHIFT INTO THE SOUTHERN PORTIONS OF CENTRAL
ALABAMA THIS EVENING AND DECREASE IN AREAL COVERAGE. THE
THUNDERSTORM ACTIVITY WILL LIKELY BE GONE BY 9PM THIS EVENING
WITH SOME LINGERING SHOWERS OVER THE SOUTHEAST COUNTIES OVERNIGHT.
THE SURFACE FRONT WILL BECOME STATIONARY BETWEEN MONTGOMERY AND
TROY SATURDAY MORNING...AND KEPT A SMALL CHANCE OF SHOWERS SOUTH
OF I-85. REMOVED RAIN CHANCES FOR SATURDAY NIGHT DUE TO LACK OF
ANY LIFT AND DEEPER MOISTURE PUSHING TO THE COASTAL AREAS.
MOISTURE WILL BEGIN TO LIFT BACK NORTHWARD ON SUNDAY AS A SHORT
WAVE TROF TRACKS EASTWARD INTO THE PLAINS STATES. DEEP PACIFIC
MOISTURE LINGERING OVER TEXAS AND SOUTH LOUISIANA WILL GET PULLED
NORTHWARD AHEAD OF THE ADVANCING UPPER TROF. AS THE SHORT WAVE
TROF PUSHES EASTWARD TOWARDS THE OHIO VALLEY REGION...THE SOUTHERN
TAIL OF THE TROF AXIS WILL INTERACT WITH DEEPER MOISTURE AND BRING
NUMEROUS SHOWERS AND THUNDERSTORMS TO CENTRAL ALABAMA MONDAY AND
MONDAY NIGHT. ONCE THE TROF PASSES OFF THE ATLANTIC COAST ON
TUESDAY...DRIER MID LEVEL AIR WILL SHIFT SOUTHWARD INTO NORTH
ALABAMA AND HIGHER RAIN CHANCES WILL BE ACROSS SOUTH ALABAMA. THE
ACTIVE SOUTHERN STREAM JET WILL KEEP THE DEEPER MOISTURE IN PLACE
ACROSS THE CENTRAL GULF COAST REGION THROUGH THE REMAINDER OF THE
WEEK...AND ABOVE AVERAGE RAIN CHANCES WILL CONTINUE WEDNESDAY AND
THURSDAY.
