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 Dec 10, 11:46 AM CST, 1 hour 27 minutes earlier.

Area forecast discussion, Dec 10, 11:46 AM CST, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1146 AM CST MON DEC 10 2012

.UPDATE...
AVIATION DISCUSSION.

&&

.DISCUSSION...

/PREVIOUS DISCUSSION EDITED TO REMOVE DATED FIRST PERIOD INFORMATION/

COLD AIR WILL MOVE IN BEHIND THE FRONT. TEMPERATURES AT 2 AM ACROSS
NEBRASKA AND KANSAS ARE IN THE SINGLE DIGITS AND TEENS. OF
COURSE...THIS AIRMASS WILL MODIFY BEFORE REACHING THE FORECAST AREA
BUT INTERESTING TO NOTE THE STRENGTH OF THE COLD AIR MOVING IN
BEHIND THE SYSTEM. THE FRONT SHOULD EXIT THE FORECAST AREA AROUND
03Z TONIGHT. MODELS HAVE BEEN TRENDING A LITTLE FASTER WITH THE
FRONT AND MOVED OUT THE PRECIPITATION A LITTLE SOONER THAN IN THE
PREVIOUS FORECAST. MODELS ARE STILL INDICATING THAT THE FRONT MAY
LINGER JUST TO THE SOUTHEAST OF THE CWA ON TUESDAY. THEREFORE...
EXPECT THE TEMPERATURE GRADIENT WILL BE RATHER SUBSTANTIAL ACROSS
THE CWA ON TUESDAY WITH LOWS RANGING FROM UPPER 20S ACROSS THE
NORTHWEST TO MID 40S ACROSS THE SOUTHEAST. MODELS STILL INDICATE A
RATHER ROBUST UPPER LEVEL WAVE MOVING IN ON WEDNESDAY. CONTINUED
POPS ACROSS THE SOUTHEAST WITH THE BOUNDARY POSSIBLY LINGERING JUST
TO THE SOUTH.

SURFACE HIGH PRESSURE WILL MOVE JUST TO THE NORTHEAST OF THE
FORECAST AREA AS THE UPPER LEVEL TROUGH AND FRONT FINALLY PUSH OF TO
THE EAST. THE LOCATION OF THE HIGH WILL SETUP A WEDGE ON THURSDAY
WITH COOLER TEMPERATURES ACROSS THE EAST AND WARM TEMPERATURES
ACROSS THE WEST WITH SOME WEAK CAD ACROSS THE APPALACHIAN MOUNTAIN.

SURFACE FLOW WILL BECOME MORE SOUTHERLY MOVING INTO THE WEEKEND AS
THE HIGH MOVES OFF TO THE EAST AND THE NEXT SYSTEM APPROACHES FROM
THE WEST. CONTINUED CHANCE POPS FOR MUCH OF THE WEEKEND WITH THE GFS
AND ECMWF REMAINING IN GOOD AGREEMENT WITH A COLD FRONT AND UPPER
LEVEL TROUGH MOVING ACROSS THE AREA. BEYOND THIS PERIOD...MODELS
SHOW THAT A BOWLING BALL TYPE TROUGH WILL MOVE IN QUICKLY BEHIND THE
FRONT WITH SOME COOLER AIR IN PLACE....BUT HAVE A SLIGHTLY DIFFERENT
EVOLUTION THAN PREVIOUS RUNS. WILL HAVE TO CONTINUE TO MONITOR THIS
SYSTEM AS WE APPROACH MID DECEMBER.

MA

&&

.AVIATION...
18Z TAF DISCUSSION.

PREDOMINANT CONDITIONS OVER MOST CENTRAL ALABAMA TAF LOCATIONS THE
NEXT SEVERAL HOURS ARE LIKELY TO REMAIN IN THE MVFR CATEGORY.
HOWEVER...THERE ARE HEAVIER POCKETS OF RAIN AND STORMS HERE AND
THERE THAT WILL BRIEFLY TAKE CONDITIONS LOWER...AND ALSO SOME
POCKETS OF LITTLE TO NO RAIN THAT ALLOWS CONDITIONS TO IMPROVE TO
VFR. I BELIEVE THE BULK OF THE LOWER CONDITIONS WILL BE RIGHT ALONG
THE LEADING EDGE OF THE MOST ACTIVE CONVECTIVE BAND...WHILE THE
IMPROVED CONDITIONS WILL COME AT THE TAIL END OF THE RAIN BUT BEFORE
A COLD FRONT ARRIVES. THE COLD FRONT IS MARKED BY A PRETTY DRASTIC
WIND SHIFT...FROM SOUTH/SOUTHWEST TO NORTHWEST...AND APPEARS TO BE
ACCOMPANIED BY A BRIEF PERIOD OF MVFR TO IFR CEILINGS. FINALLY...
CONFIDENCE IS ALSO RELATIVELY LOW REGARDING THE ULTIMATE SCATTERING
OUT OF THE CLOUDS OVERNIGHT TONIGHT. MODELS TYPICALLY DON'T HANDLE
THE CLEARING TREND AFTER COLD FRONTS LIKE THIS VERY WELL...AND I
WOULDN'T BE SURPRISED IF THE LOWER CLOUDS ACTUALLY STUCK AROUND
LONGER THAN CURRENTLY FORECAST.
