The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, May 1, 1:45 PM CDT, 3 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND TX 145 PM CDT SAT MAY 1 1999 BLOCKING PATTERN OVER THE CENTRAL U.S. FINALLY BEGINNING TO BREAK UP. MAIN CHALLENGE THIS PERIOD IS TO FIGURE OUT THE JUST HOW QUICKLY THE UPPER LOW WILL LIFT OUT OF THE SWRN US...AND MUCH OF THIS WILL DEPEND ON THE TIMING AND MOVEMENT OF THE OTHER LOW OFF THE SERN U.S. COAST. IT LOOKS LIKE THE SERN LOW WILL FINALLY BEGIN TO PROGRESS EWD...AND THIS SHOULD ALLOW THE LOW TO OUR WEST TO BEGIN LIFTING OUT ON SUNDAY. FOR TONIGHT...SIGNIFICANT CONVECTION IS THE MAIN CONCERN. I BELIEVE THE DRYLINE WILL CONTINUE TO ADVANCE EWD THIS AFTERNOON AND KICK OFF STORMS. WITH THE LOW BEGINNING TO LIFT...I EXPECT A SERIES OF SHORTWAVES TO EJECT OUT OF THE SYSTEM...AND THIS WILL PROBABLY KEEP CONVECTION ACTIVE TONIGHT. TOMORROW THE LOW BEGINS TO LIFT...BUT I STILL EXPECT SOME LINGERING CLOUDS AND PCPN DURING THE MORNING HOURS. LOOKS LIKE SOME DRIER SFC AIR WILL SWEEP IN FROM THE WEST DURING THE AFTERNOON TOMORROW AS THE SFC LOW LIFTS NORTH...BUT WINDS SHOULD QUICKLY SWITCH BACK AROUND TO A SLY OR SELY DIRECTION LATE SUNDAY NIGHT...AND THEN BECOME MORE SWLY DURING THE DAY ON MONDAY FOR A BIT OF A WARMUP. UPPER LEVEL FLOW PATTERN ON MONDAY SHOULD BE NEARLY ZONAL. PRELIM TEMPS/POPS... MAF 52/78/53/85 4200 CNM 52/81/52/87 3100 MRF 45/77/45/80 2100 P07 58/79/56/86 3100 DJK
