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 San Angelo, TX wrote its last area forecast discussion before this flash flood warning went out at Mar 30, 4:16 PM CDT, 52 minutes earlier.

Area forecast discussion, Mar 30, 4:16 PM CDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
416 PM CDT FRI MAR 30 2007

.DISCUSSION...
CONSOLIDATED FRONTAL BOUNDARY NOW EXTENDS FROM EAST OF ABILENE
TO EAST OF OZONA...AND IS PUSHING SLOWLY SOUTHEAST AS A COLD FRONT.
BAND OF STRONG TO SEVERE STORMS ACCOMPANIES THIS FRONT ACROSS THE
NORTHEAST HALF OF WEST CENTRAL TX. WIDELY SCATTERED SOTRMS EXIST
ACROSS OTHER PARTS OF THE WARM SECTOR. THE LINE COULD FILL IN TO
THE SOUTH THIS EVENING...AND SHOULD TAKE UNTIL WELL AFTER MIDNIGHT
BEFORE CLEARING SOUTH FAR SOUTHEAST COUNTIES. COOLER AND DRIER AIR
HAS WORKED INTO OUR WESTERN COUNTIES BEHIND THE FRONT.

BASED ON THESE TRENDS...WE HAVE MADE RECENT ADJUSTMENTS TO THE
FORECAST. HAVE CANCELLED THE TORNADO WATCH AND FLASH FLOOD WATCH
FOR THE WESTERN BIG COUNTRY AND WESTERN CONCHO VALLEY. MAY SEE
A FEW ADDITIONAL SHOWERS OR STORMS IN WESTERN AREAS THROUGH LATE
EVENING...AS THE UPPER TROUGH OVER SOUTHERN/CENTRAL ROCKIES
LIFTS OUT TO THE NORTHEAST.

A DRIER AIRMASS WILL BE OVER OUR REGION THIS WEEKEND. PLEASANT
TEMPERATURES WITH LOWS NEXT COUPLE OF NIGHTS IN UPPER 40S TO
LOWER 50S AND HIGHS FROM THE LOWER 70S SATURDAY TO THE LOWER
80S SUNDAY. INCREASINGLY SOUTHERLY FLOW MONDAY SHOULD PROMOTE
HIGHS REACH THE 80-85 DEGREE RANGE.

THE RAIN CHANCE NOW LOOKS MARGINAL FOR TUESDAY. WEAK SOUTHERN
STREAM SHORTWAVE TROUGH WILL PUSH EAST ACROSS TEXAS BY
TUESDAY. A DEEPENING NORTHERN STREAM TROUGH INTO THE NORTHERN
AND CENTRAL PLAINS WILL PUSH A SURFACE COLD FRONT DOWN ACROSS
OUR AREA ON TUESDAY. MOISTURE AVAILABIILITY APPEARS MARGINAL
AND DECIDED TO LOWER THE POPS TUESDAY. COOLER AIR MOVES
DOWN INTO OUR REGION FOR THE MIDDLE OF NEXT WEEK WITH SURFACE
HIGH PRESSURE RIDGING ACORSS THE PLAINS. LACK OF GULF MOISTURE
RETURN AND DEVELOPING NORTHWEST FLOW ALOFT SHOULD KEEP THE
FORECAST DRY INTO LATE NEXT WEEK.
