What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Aug 13, 8:29 PM CDT | Hail 1 | Tye, TX |
NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Aug 13, 3:00 PM CDT, 5 hours 6 minutes before
WEST CENTRAL TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 300 PM CDT TUE AUG 13 2002 AN UPPER LEVEL TROUGH IS DIGGING SOUTH INTO NORTH TEXAS...WEAKENING THE RIDGE WHICH STRETCHES FROM THE WEST COAST...TO TEXAS. ON THE SURFACE A COLD FRONT STRETCHES FROM EASTERN WISCONSIN TO SOUTH OF MIDLAND. THE FRONT IS MAKING SLOW SOUTH/SOUTHEAST PROGRESS NEAR 15 KNOTS BETWEEN LUBBOCK AND ABILENE. TEMPERATURES AHEAD OF THE FRONT ARE IN THE LOWER 90S...AND 70 TO 80 DEGREES IN THE TEXAS PANHANDLE. CURRENT RADAR TRENDS SHOW THE CUMULUS FIELD STARTING TO DEVELOP ALONG THE COLD FRONT. TONIGHT THROUGH WEDNESDAY NIGHT... WITH THE COLD FRONT PUSHING SOUTH INTO WEST CENTRAL TEXAS...ALONG WITH THE MOIST AND UNSTABLE ENVIROMENT ALONG THE FRONT AND WITH ISENTROPIC LIFT BEHIND THE FRONT...WILL BUMP UP POPS FOR THE NORTHERN BIG COUNTRY. ALSO WITH THE STRONG THETA-E RIDGE...GOOD LAPSE RATES AND FULL SUN AHEAD OF THE FRONT MOVING IN THIS EVENING EXPECT A FEW SEVERE STORMS POSSIBLE. WITH THE BEST LOW LEVEL SHEAR AND UPPER SUPPORT (RIGHT ENTRANCE OF AN UPPER JET) TO THE NORTH...THE BEST CHANCE FOR SEVERE WILL BE ACROSS THE BIG COUNTRY. ALSO WITH PW/S IN THE 1.5 TO 2.0 INCH RANGE EXPECT HEAVY RAIN IN A FEW LOCATIONS ACROSS THE NORTHERN AND CENTRAL COUNTIES. BOTH THE AVN AND ETA MODELS ARE SHOWING THE FRONT SLOWLY EDGING SOUTH THROUGH THE BIG COUNTRY TONIGHT...BEFORE STALLING OUT SOMEWHERE IN THE CENTRAL OR SOUTHERN COUNTIES. EXPECT THE FRONT TO STALL OUT...HOWEVER WITH ANY OUTFLOW BOUNDARIES PUSHING SOUTH ACROSS THE CENTRAL COUNTIES...THIS COULD PUSH THE FRONT TO NEAR INTERSTATE 10. THE AVN HAS BACKED OFF OF ITS PREVIOUS AGRESSIVENESS...BUT IS STILL TOO COOL BEHIND THE FRONT...TRYING TO BRING IN 50S FOR THE NORTHERN BIG COUNTRY. HOWEVER WITH NOTABLY COOLER AFTERNOON TEMPS BEHIND THE FRONT IN THE PANHANDLE TODAY AND THE FORECAST CLOUD COVER...WILL DROP HIGHS A CATEGORY ON WEDNESDAY NORTH OF THE FRONT IN THE BIG COUNTRY. THURSDAY THROUGH TUESDAY... THE UPPER LEVEL RIDGE VERY SLOWLY BUILDS IN FROM THE WEST. HOWEVER THE RIDGE IS NOT EXACTLY ONE OF THOSE TYPICAL DOMINATE TYPES. ONCE THE WARM FRONT LIFTS OUT...WITHOUT ANY SIGNIFICANT CHANGE THROUGH NEXT WEEK...WILL CONTINUE WITH THE WARMER (TO NEAR NORMAL) AND DRY CONDITIONS. CCF PRELIMS... ABI 065/085/068/090 4300 SJT 067/089/069/092 3200 JCT 068/090/070/093 2200 .SJT...NONE. 24
