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 Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 1, 3:01 PM CDT, 1 hour 43 minutes earlier.

Area forecast discussion, Oct 1, 3:01 PM CDT, 1 hour 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
301 PM CDT THU OCT 1 2009

.DISCUSSION...
IMMEDIATE FORECAST CONCERNS CENTERED ON ONGOING SEVERE EVENT.
SOMEWHAT BROKEN LINE OF STORMS EXTENDS ALONG THE COLD FRONTAL
BOUNDARY FROM ABOUT MIAMI TO MUSKOGEE TO ADA. MEASURED WINDS TO 70
MPH HAVE BEEN RECORDED WITH THESE STORMS. SEVERE POTENTIAL WILL
CONTINUE THROUGH THE AFTERNOON ALONG AND IN ADVANCE OF THE FRONT WITH
LOCAL MESOANALYSIS SHOWING OVER 2000 J/KG OF CAPE...AND A STEADILY
WEAKENING CAP...IN ADDITION TO AMPLE DEEP LAYER SHEAR.

LINE HAS BEEN MOVING EASTWARD AT A FAIRLY FAST RATE OF SPEED...AND
DISTANCE SPEED TOOL AND LOCAL WRF MODEL BOTH INDICATE THAT THE
LINE WILL BE VERY CLOSE TO EXITING THE FORECAST AREA BY 00Z.
CURRENT PLAN IS TO HANG ONTO LIKELY POPS SOUTH AND EAST OF A LINE
FROM BERRYVILLE...TO FORT SMITH...TO HUGO THROUGH 03Z BEFORE GOING
COMPLETELY DRY...HOWEVER...WILL REEVALUATE THINGS FURTHER IN THE
NEXT HOUR AND AMEND AS NECESSARY. ALSO CONCERNING THE SEVERE
THUNDERSTORM WATCH...PLAN TO CLEAR COUNTIES LOCATED BEHIND THE
FRONT CLOSE TO PUBLISH TIME.

VERY COOL AND DRY AIR IS LOCATED BEHIND THE BOUNDARY. MESONET OBS
SHOWING A 20 TO 25 DEGREE DEW POINT DROP FOLLOWING FRONTAL
PASSAGE. WITH CLEAR SKIES EXPECTED...THIS SHOULD ALLOW FOR ANOTHER
VERY COOL NIGHT...WITH LOWS VERY NEAR TO THOSE FROM THIS PAST
TUESDAY MORNING.

A COUPLE OF COOL AND DRY DAYS WILL OCCUR TOMORROW AND SATURDAY.
MOISTURE BEGINS TO RETURN TO THE AREA ONCE AGAIN LATE
SATURDAY...WITH THUNDERSTORM CHANCES CONTINUING THROUGH AT LEAST
THE BEGINNING OF NEXT WEEK. CURRENTLY HAVE VERY LITTLE CONFIDENCE
IN THE EXTENDED FORECAST...WITH MODELS SHOWING LITTLE AGREEMENT
AMONG THEMSELVES OR WITH THEIR RUN-TO-RUN COUNTERPARTS. ONLY MADE
A FEW CHANGES TO THE INHERITED GRIDS AS A RESULT. MAIN CHANGE WAS
TO BACK OFF ON POPS SOMEWHAT TOWARD THE MIDDLE OF NEXT WEEK...WITH
MODELS NOT REALLY FAVORING ANY ONE TIME PERIOD FOR PRECIPITATION
AT THIS TIME.
