What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Jul 15, 3:13 PM CDT, 2 hours 8 minutes earlier.

Area forecast discussion, Jul 15, 3:13 PM CDT, 2 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
313 PM CDT MON JUL 15 2013

.DISCUSSION...

IN THE SHORT TERM...ALABAMA WILL REMAIN ON THE SOUTHERN PERIPHERY
OF A RATHER LARGE UPPER LEVEL HIGH CENTERED OVER THE OHIO VALLEY.
THE EASTERLY FLOW ACROSS THE SOUTHEAST STATES WILL KEEP US IN A
RATHER TROPICAL AIR MASS THROUGH AT LEAST THE MIDDLE OF THE WEEK.
IT LOOKS LIKE MOISTURE DEPTH TOMORROW WILL BE A BIT LESS THAN
TODAY...SO EXPECT FEWER SHOWERS/STORMS TOMORROW. BY THE MIDDLE TO
END OF THE WEEK...PWAT AND K-INDEX VALUES RETURN TO MORE
NORMAL/CLIMO LEVELS...SO WOULD EXPECT NORMAL/CLIMO LEVEL POPS. ANY
SHOWERS AND STORMS EXPERIENCED THROUGH THE PERIOD...WHILE EFFICIENT
RAIN PRODUCERS...ARE NOT LIKELY TO PRODUCE EXCESSIVE WINDS OR
HAIL.

BY THE WEEKEND...THE RIDGE IS FORECAST TO BREAK DOWN AS A LOWER
AMPLITUDE LONGWAVE TROUGH DIPS INTO THE EASTERN CONUS. TIMING OF
SHORTWAVES WITHIN THIS LONGWAVE PATTERN BECOMES INCREASINGLY
PROBLEMATIC...AND ADDING ANY VALUE ON TOP CLIMO POPS BECOMES
INCREASINGLY DIFFICULT. WITH THE BREAK DOWN OF THE RIDGE...HIGH TEMPS
AGAIN DROP TO BELOW CLIMO VALUES.

/61/

&&

.AVIATION...
18Z TAF DISCUSSION.

MAINLY VFR CONDITIONS EXPECTED THROUGH THE AFTERNOON. SHOWERS AND
STORMS COULD BRING IFR TO MVFR CIGS/VIS AT ANY SITE. KMGM AND KTOI
STAND THE BEST CHANCE OF SEEING THIS DURING THE 21-00Z TIME FRAME
AS THUNDERSTORMS ORGANIZE AND MOVE WESTWARD FROM GEORGIA.
CONDITIONS SHOULD IMPROVE AFTER SUNSET WITH CIGS AROUND DAYBREAK
NOT EXPECTED TO BE PARTICULARLY IMPACTFUL AS A DROP IN LOW-LEVEL
MOISTURE SHOULD LEAD TO ONLY INTERMITTENT MVFR CONDITIONS.
