What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Apr 17, 12:50 PM CDT, 2 hours 14 minutes earlier.

Area forecast discussion, Apr 17, 12:50 PM CDT, 2 hours 14 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1250 PM CDT WED APR 17 2013

.UPDATE...
AVIATION DISCUSSION.

&&

.DISCUSSION...

HIGH CLOUDS STREAMING ACROSS THE AREA HAVE PREVENTED A WIDESPREAD
CU FIELD FROM DEVELOPING THIS MORNING. EXPECT THAT TO CHANGE OVER THE
NEXT COUPLE HOURS AS SURFACE TEMPS CONTINUE TO WARM AND AN UPPER
LEVEL IMPULSE CROSSES NORTHWEST ALABAMA. CURRENT TEMPS IN THE MID
TO UPPER 70S WILL CLIMB IN TO THE MID 80S. THE UPPER LEVEL IMPULSE
WILL HELP KICK OFF A FEW SHOWERS AND POSSIBLY A THUNDERSTORM THIS
AFTERNOON...ALTHOUGH COVERAGE IS EXPECTED TO BE SIMILAR TO
YESTERDAY AND MOST LOCATIONS WILL REMAIN DRY.

MADE TWEAKS TO HOURLY TRENDS AND MINOR CHANGES TO HIGHS THIS
AFTERNOON. INCREASED POPS TO SLIGHT CHANCE WORDING ACROSS THE WEST
PER NEAR TERM MODEL GUIDANCE. BEST CHANCES REMAIN ACROSS THE
NORTHEAST.

14

&&

.AVIATION...
18Z TAF DISCUSSION.

BASED ON PERSISTENCE OVER THE LAST COUPLE DAYS...HAVE KEPT VFR
CONDITIONS IN THROUGH THE TAF PERIOD. MODEL GUIDANCE HAS OVERDONE
LOWER CIGS AND VIS THE PAST SEVERAL NIGHTS...AND WITH THE MAIN
MOISTURE PLUME TO OUR WEST AND WARM TEMPERATURES
OVERNIGHT...CONFIDENCE AND CHANCES FOR ANY REDUCTIONS IN PREVAILING
VFR CONDITIONS REMAIN TOO LOW.

ISOLATED TO SCATTERED SHOWERS AND TS ARE POSSIBLE THIS
AFTERNOON...ESPECIALLY ACROSS THE NORTH. CHANCES AT ANY TERMINAL ARE
TOO LOW TO INCLUDE AT THIS TIME. WILL MONITOR DEVELOPMENT UPSTREAM
AND MAKE ADJUSTMENTS IF NEEDED. ACTIVITY WILL DIMINISH WITH SUNSET.

14

&&

.PREV DISCUSSION... /ISSUED 627 AM CDT WED APR 17 2013/

SHORT TERM...TODAY THROUGH FRIDAY.

TODAYS WEATHER SHOULD BE NEARLY IDENTICAL TO YESTERDAY WITH REGARD
TO TEMPERATURES. THE UPPER RIDGE WAS JUST TOO STRONG FOR
THUNDERSTORM DEVELOPMENT ON TUESDAY...BUT THE MODELS ARE SHOWING
A WEAKNESS IN THE UPPER RIDGE ACROSS NORTH ALABAMA TODAY WITH
ABOUT A 20 METER DROP IN 500MB HEIGHTS. THIS SHOULD ALLOW FOR MORE
CONVECTIVE DEVELOPMENT FOR AREAS NORTH OF I-20...ESPECIALLY THE
NORTHEAST COUNTIES. THE ACTIVITY WILL DIMINISH QUICKLY AFTER
SUNSET. A DIGGING UPPER TROF OVER THE ROCKY MOUNTAIN STATES WILL
PRODUCE A SURFACE LOW OVER OKLAHOMA TONIGHT. THE AMPLIFIED UPPER
FLOW PATTERN WILL CREATE A STRONGER RIDGE DOWNSTREAM AND KEEP A
LID ON CONVECTIVE DEVELOPMENT ACROSS CENTRAL ALABAMA DURING THE
DAY THURSDAY. THE SURFACE LOW WILL DEEPEN AND TRACK NORTHEAST
TOWARDS THE OHIO VALLEY REGION THURSDAY NIGHT A PUSH A STRONG COLD
FRONT ACROSS THE CENTRAL GULF STATES. AN INTENSE SQUALL LINE WILL
DEVELOP JUST AHEAD OF THE COLD FRONT. THE SQUALL LINE SHOULD ENTER
LAMAR AND MARION COUNTIES AROUND 2 AM FRIDAY AND BE NEAR THE I-65
CORRIDOR BY 6 AM FRIDAY. SHEAR PROFILES ARE VERY IMPRESSIVE WITH A
LOW LEVEL JET NEAR 50 KNOTS AND 0-1KM BULK SHEAR OF 40-50 KNOTS.
THIS WILL SUPPORT THE THREAT OF DAMAGING STRAIGHT-LINE WINDS
ASSOCIATED WITH BOW SEGMENTS ALONG THE QLCS. ISOLATED TORNADOES
ARE POSSIBLE AS MODIFIED FORECAST SOUNDINGS JUST AHEAD OF THE QLCS
SHOW SURFACE BASED CAPE VALUES OF 500-600 J/KG...WHICH SHOULD
SUPPORT SOME ROTATING UPDRAFTS. THE THREAT OF DISCRETE SUPERCELLS
AHEAD OF THE QLCS APPEARS LOW AT THIS TIME AS THE AIR MASS IS
CAPPED ALOFT. IT ALSO SEEMS LIKELY THAT THE QLCS WILL WEAKEN AS IT
PUSHES EASTWARD ACROSS ALABAMA. THE UPPER LEVEL FORCING DECREASES
AS THE UPSTREAM TROF BECOMES LESS AMPLIFIED. THE HIGHEST THREAT
FOR SEVERE STORMS WILL BE WEST OF I-65.

TEMPERATURES WILL QUICKLY FALL INTO THE 50S BEHIND THE COLD FRONT
..AND THEN SLOWLY RISE INTO THE LOWER TO MIDDLE 60S FRIDAY
AFTERNOON AS THE CLOUDS DECREASE. EVEN THOUGH THE FRONT WILL PUSH
OUT OF CENTRAL ALABAMA BY MID AFTERNOON FRIDAY...THE UPPER FLOW
REMAINS OUT OF THE SOUTHWEST AND THE DEEPER MOISTURE WILL HANG UP
ACROSS SOUTHEAST ALABAMA FRIDAY EVENING. THE RAIN SHOULD FINALLY
MOVE OUT OF THE SOUTHEAST COUNTIES BY 9 OR 10 PM FRIDAY.

58/ROSE

LONG TERM...SATURDAY THROUGH TUESDAY.

HIGH PRESSURE WILL BUILD INTO THE AREA THIS WEEKEND AND RESULT IN
COOL NIGHTS AND MILD AFTERNOONS. THE MODELS ARE INDICATING AN
INFLUX OF ATLANTIC MOISTURE SUNDAY NIGHT AND POSSIBLY A FEW
SHOWERS ON MONDAY. FOR NOW WILL SHOW AN INCREASE IN CLOUD COVER
FOR SUNDAY NIGHT AND MONDAY...BUT KEEP A RAIN FREE FORECAST.
ANOTHER STORM SYSTEM WILL MOVE INTO THE SOUTHERN PLAINS STATES BY
TUESDAY...AND THERE COULD BE A FEW THUNDERSTORMS AS FAR EAST AS
ALABAMA.
