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 Mar 31, 6:48 PM CDT, 1 hour 17 minutes earlier.

Area forecast discussion, Mar 31, 6:48 PM CDT, 1 hour 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
648 PM CDT THU MAR 31 2016

.UPDATE...
FOR 00Z AVIATION.

&&

.DISCUSSION...

00Z BALLOON SOUNDING IS IN PROGRESS... WILL DETERMINE THE DEGREE
TO WHICH INSTABILITY HAS INCREASED ACROSS THE CENTRAL PORTION OF
THE STATE. SURFACE DATA CONTINUES TO INDICATE THE MOST UNSTABLE
NEAR SURFACE AIRMASS IS LOCATED ACROSS THE SOUTHERN AND WESTERN
PORTION OF OUR AREAS WITH TEMPERATURES RANGING FROM 77 NEAR
FAYETTE IN FAYETTE COUNTY TO 79 NEAR DEMOPOLIS IN MARENGO COUNTY.
TEMPERATURES HAVE MANAGED TO WARM TO 80 AT JACKSON MISSISSIPPI AND
83 AT GREENWOOD MISSISSIPPI.

SATELLITE CONTINUES TO INDICATE BREAKS IN THE CLOUDS OVER MUCH OF
OUR AREA TO ALLOW SURFACE HEATING TO BRING TEMPERATURES INTO THE
70S ACROSS MOST LOCATIONS. AN EXCEPTION TO THIS REMAINS ACROSS
NORTHEAST JEFFERSON COUNTY NORTHEAST INTO PORTIONS OF SAINT CLAIR
AND BLOUNT COUNTIES AND FURTHER NORTHEAST INTO ETOWAH COUNTY
WHERE TEMPERATURES HAVE REMAINED IN THE 60S FOR MUCH OF THE DAY.
EXPECT SURFACE TEMPERATURES TO CONTINUE TO MODERATE ACROSS OUR
EASTERN AND CENTRAL COUNTIES AS LOW LEVEL WARM ADVECTION CONTINUES
WHILE OUR WESTERN COUNTIES WILL BEGIN TO EXPERIENCE MORE CLOUD
COVER FROM CONVECTION ONGOING IN MISSISSIPPI THROUGH SUNSET.

AN OUTFLOW BOUNDARY FROM THE ACTIVITY THIS MORNING REMAINS ACROSS
EASTERN MISSISSIPPI AND EXTENDING ACROSS THE NORTHERN PORTION OF
OUR AREA. ANY STORMS THAT DEVELOP OR MOVE NEAR THIS BOUNDARY WILL
HAVE ENHANCED POTENTIAL FOR SEVERE WEATHER.

DEW POINTS HAVE INCREASED TO NEAR 70 DEGREES ACROSS WESTERN
ALABAMA WITH READINGS OF 69 AND PICKENS COUNTY AND 68 AT BOTH
FAYETTE AND DEMOPOLIS. DEW POINTS ARE AROUND 60 IN CHEROKEE COUNTY
IN THE NORTHEAST PORTION OF OUR AREA. EXPECT LOW LEVEL MOISTURE
ADVECTION TO CONTINUE TO INCREASE AS SOUTHERLY WINDS PERSIST
ACROSS THE REGION.

NEXRAD VAD WIND PROFILES INDICATE DIRECTIONAL WIND SHEAR BOTH AT
BMX AND MXX WITH LOW LEVEL WINDS AROUND 20 KNOTS WITH WEST WINDS
DETECTED AROUND 12000 FEET FROM BOTH RADARS. WIND VELOCITIES HAVE
INCREASED ACROSS THE LOWEST 6000 FEET BY ABOUT 10 TO 20 KNOTS
SINCE 400 PM CDT.

OVERALL EXPECT THE GREATEST SHORT-TERM SEVERE POTENTIAL ACROSS OUR
WESTERN COUNTIES. NEAR-SURFACE THERMODYNAMIC INSTABILITY
DECREASES THE FURTHER EAST ONE GOES ACROSS OUR AREA... HOWEVER...
WARM ADVECTION AND MOISTURE ADVECTION IS MODERATING THE AIRMASS
AND DESPITE THE UPCOMING LOSS OF DAYTIME HEATING... NEAR SURFACE
INSTABILITY WILL LIKELY INCREASE. ADDITIONALLY...THE POTENTIAL
DEVELOPMENT OF THE LOW LEVEL JET COULD ALSO HELP ENHANCE THE LOW
LEVEL WIND FIELDS FOR THE ENVIRONMENT TO BECOME FURTHER FAVORABLE
FOR SEVERE WEATHER INCLUDING TORNADOES.

05

&&

.AVIATION...
00Z TAF DISCUSSION.

NEXT ROUND OF SHOWERS AND THUNDERSTORMS POISED TO SWEEP ACROSS
CENTRAL ALABAMA DURING THE NEXT 6-8 HOURS....LIKELY AFFECTING MOST
(IF NOT ALL) CENTRAL ALABAMA TAF SITES. BEFORE THE RAIN...
CEILINGS WERE BOUNCING OVER AND UNDER THE 3000 FT MARK. I THINK
THE MAIN ROUND OF STORMS WILL MOVE ACROSS DURING THE 00Z TO 06Z
PERIOD...BUT SOME SHOWERS MAY LINGER FOR SEVERAL HOURS AFTER THAT.
COMPUTER MODEL OUTPUT STRONGLY SUGGESTS CEILINGS IN THE MVFR
CATEGORY (AT BEST) THROUGH THE REMAINDER OF THE NIGHT (EVEN AFTER
THE RAIN MOVES OUT). TRIED MY BEST TO TIME THE WIND SHIFT
ASSOCIATED WITH COLD FRONT PASSAGE. FRONT MAY ACTUALLY NOT GET TO
TOI DURING THIS TAF VALID PERIOD.

/61/

&&

.FIRE WEATHER...

MOISTURE VALUES WILL CONTINUE TO INCREASE THIS MORNING AS RAIN AND
STORMS MOVE INTO WEST CENTRAL ALABAMA...AND MOVE EASTWARD ACROSS THE
AREA THROUGH THE MORNING. GUSTY SOUTH TO SOUTHEASTERLY WINDS ARE
EXPECTED TODAY...OUTSIDE OF ANY CONVECTION. ADDITIONAL STORMS ARE
EXPECTED LATE THIS AFTERNOON AND OVERNIGHT. A SLOW MOVING FRONT WILL
STALL ACROSS THE AREA...AND ADDITIONAL ROUNDS OF MODERATE TO HEAVY
RAINFALL AND STORMS ARE POSSIBLE THROUGH FRIDAY EVENING. THE THREAT
OF RAIN WILL END ONCE THE FRONT CLEARS THE AREA FRIDAY NIGHT. DRY
CONDITIONS RETURN FOR THE WEEKEND. NO CRITICAL FIRE WEATHER
CONDITIONS ARE EXPECTED THROUGH THE FORECAST PERIOD.

&&

.HYDROLOGY...

MOST OF THE HEAVIER RAIN SO FAR HAS BEEN IN OUR NORTHWEST
COUNTIES(I.E., MARION, LAMAR, WINSTON, FAYETTE AND WALKER) WHERE
AMOUNTS SO FAR HAVE AVERAGED ONE TO TWO INCHES...WITH VERY LOCALIZED
TOTALS TO THREE INCHES.  ELSEWHERE MOST LOCATIONS HAVE RECEIVED AN
INCH OR LESS SO FAR.  ALTHOUGH USGS GAGES INDICATE STREAM FLOWS NOW
AT OR SOMEWHAT ABOVE NORMAL IN THE NORTHWEST COUNTIES...MOST OTHER
STREAMS STILL REMAIN NEAR OR BELOW NORMAL LEVELS. THIS SUGGESTS THAT
MOST AREA STREAMS CAN STILL HANDLE A FAIR AMOUNT OF RUNOFF FROM THE
RAINFALL THAT IS YET TO COME TONIGHT INTO FRIDAY.  FLOOD WARNINGS
ARE CURRENTLY ISSUED FOR THE TOMBIGBEE RIVER AND FOR SELDEN DAM ON
THE LOWER BLACK WARRIOR FOR MINOR FLOODING.  BEFORE ALL IS SAID AND
DONE COULD STILL SEE A FEW OTHER LOCATIONS REACH MINOR FLOOD STAGE
BUT STILL NOT EXPECTING MAJOR FLOOD EVENT TO UNFOLD ON AREA RIVERS.
AT THIS TIME MODELS SUGGEST THERE COULD BE ANOTHER ROUND OF HEAVY
RAIN (PERHAPS ONE TO TWO INCH AVERAGES) ACROSS SOME OF OUR NORTHERN
AREAS TONIGHT. THEN LIKELY TO SEE ANOTHER ROUND OF SIMILAR TOTALS
DEVELOP ACROSS THE EXTREME SOUTHERN SECTIONS FRIDAY AFTERNOON AND
EVENING. IN GENERAL EXPECT ANOTHER ONE TO THREE INCHES ACROSS
CENTRAL ALABAMA BY THE TIME THE RAIN TAPERS OFF BY EARLY
SATURDAY...WITH LOCALIZED HIGHER TOTALS POSSIBLE IN AREAS OF
TRAINING ECHOES.
