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 Jul 10, 3:17 PM CDT, 3 hours 40 minutes earlier.

Area forecast discussion, Jul 10, 3:17 PM CDT, 3 hours 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
317 PM CDT TUE JUL 10 2007

.DISCUSSION...OTHER THAN THE ADDED WORKLOAD OF NOW ACTUALLY HAVING
GRASS TO MOW...NOT GOING TO COMPLAIN MUCH ABOUT THE FORECAST FOR
THE NEXT WEEK.

MODELS IN GOOD AGREEMENT GENERALLY THROUGH THE FIRST 84 HOURS...
ALTHOUGH SOME CONCERNS IN THAT NEITHER NAM NOR GFS REALLY SEEMED
TO DO WELL IN THE INITIAL PERIOD TODAY. HOWEVER...MORE LARGE
SCALE/SYNOPTIC SCALE INFLUENCES HIGHLIGHTED BY BOTH MODELS SHOULD
BECOME MORE PREVALENT BY TOMORROW. AS TROUGH SHARPENS ACROSS THE
EASTERN STATES...THAT WILL PUT US IN NORTHWESTERLY FLOW...AND ON
THE FRINGES OF CONCERN FOR MCS/DERECHO ACTIVITY...WHICH WOULD MOST
LIKELY AFFECT SOUTHWESTERN PORTIONS OF THE FORECAST AREA THURSDAY.
BY FRIDAY...A FAIRLY VIGOROUS SHORT WAVE IN THE NORTHWEST FLOW
SHOULD BRING ANOTHER BOUT OF DECENT RAIN CHANCES. EXPECT TO SEE A
BIT OF A BREAK IN THE ACTION FOLLOWING THE PASSAGE OF THIS WAVE ON
SATURDAY.  THEN...WITH THE RIDGE STRENGTHENING/SHARPENING OVER THE
WEST...GFS SEEMS TO BREAK OFF A BIT OF A LOW IN THE BASE OF THE
TROUGH...WHICH LINGERS WHILE THE NORTHERN PORTION OF THE TROUGH
SHEARS OUT. AFTER A BRIEF STINT OVER THE MIDWEST...BOTH GFS AND
EURO DRIFT THIS WEAKNESS EASTWARD TO THE MISSISSIPPI VALLEY...
ALTHOUGH THERE ARE SOME TIMING DIFFERENCES. EITHER WAY...THE
POSITION OF THE BERMUDA HIGH AND UPPER LEVEL WEAKNESS APPEAR AT
LEAST TO OFFER NORMAL TO SLIGHTLY ABOVE NORMAL RAIN CHANCES FROM
SUNDAY THROUGH TUESDAY. EXPECT TEMPS TO HOLD NEAR NORMAL FOR THE
MOST PART...ALTHOUGH WE MAY SEE SLIGHTLY COOLER NIGHTS IN THE
NORTHWEST FLOW UNTIL SOUTHERLY FLOW RETURNS.

.AVIATION...18Z TAF DISCUSSION.

SCATTERED AND THUNDERSTORMS HAVE DEVELOPED ACROSS THE AREA AND WILL
AFFECT THE BMX...EET TCL AND ANB AIRFIELDS BETWEEN 19 AND 23Z...AND
LIKELY APPROACH MGM AND TOI BY 22Z.  CEILINGS WILL RANGE FROM 3000
TO 5000 FEET...DROPPING TO 2000 FEET OR LESS IN ASSOCIATION WITH
THUNDERSTORMS.  VISIBILITY WILL ALSO BE DIMINISHED...AS LOW AS 1/2
MILE IN ASSOCIATION WITH THE HEAVIEST DOWNPOURS.  PRECIPITATION WILL
LIKELY CONTINUE THROUGH THE OVERNIGHT HOURS.  ELECTED TO INCLUDES
VCTS OR SHRA AT MOST LOCATIONS...WITH THUNDERSTORMS BECOMING MORE
LIKELY BEFORE NOON AGAIN TOMORROW.
