What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Jul 26, 9:30 PM CDT | Hail 0.75 | Trenton, MO |
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.
The watch it was issued in

Area forecast discussion, Jul 26, 3:11 PM CDT, 6 hours 18 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 311 PM CDT FRI JUL 26 2002 MAIN FORECAST CONCERNS THIS AFTERNOON CONTINUE TO BE WITH CHANCES OF STORMS IN NORTHERN PART OF FORECAST AREA AND TEMPERATURES. WILL LEAVE HEAT ADVISORY THAT WAS ISSUED EARLIER IN PLACE...EVEN THOUGH SOME PLACES ON ITS NORTHERN FRINGES MAY NOT QUITE REACH CRITERIA. THE PROLONGED HEAT OVER THE WEEKEND WILL STILL HAVE AN EFFECT. NOTE TO USERS OF THE KANSAS CITY INTERNATIONAL OBSERVATION...IT WAS NOTED TODAY THAT THE DEWPOINT SENSOR WAS READING TOO HIGH. A CORRECTION TO THE READING WAS STARTED AS OF 2 PM. THIS WILL AFFECT HEAT INDEX READINGS. EVEN AT THAT...AS THE OUTFLOW BOUNDARY FROM LAST NIGHTS CONVECTION LIFTED NORTH TODAY...AND TEMPERATURES RETURNED TO THE SOUTH...TEMPERATURES MADE A NICE JUMP THIS AFTERNOON. BETTER THETA E LIFT NOTED IN NORTHERN MISSOURI THIS AFTERNOON AND EVENING. EXPECT DEVELOPMENT THIS EVENING NEAR THE BOUNDARY...ESPECIALLY WITH PROFILERS SHOWING A 700 MB WAVE CURRENTLY IN CENTRAL NEBRASKA. AVN BRINGS THIS WAVE INTO FORECAST AREA OVERNIGHT...SWINGING EAST OF AREA BY 18Z ON SATURDAY. MAY BE SOME REMNANTS OF PRECIPITATION IN NORTHEAST PART OF FORECAST AREA SATURDAY MORNING...BUT ENOUGH UNCERTAINTY OF TIMING AND LOCATION OF PRECIPITATION...WILL NOT ADD POPS TO FORECAST SATURDAY MORNING. SOMETHING TO BE WATCHED. WILL HAVE TO SEE WHAT ANY OUTFLOWS FROM OVERNIGHT STORMS MIGHT DO...BUT EXPECT AN EVEN FASTER RECOVERY ON SATURDAY AS SLIGHTLY STRONGER SHORT WAVE IN THE NORTHERN STREAM PASSES THROUGH NORTHERN PLAINS. 850 TEMPS WOULD SAY EVEN A FEW DEGREES HOTTER ON SATURDAY. ANOTHER WEAK WAVE IN THE FLOW ON TAP FOR SATURDAY NIGHT...BUT BOUNDARY SHOULD BE JUST A BIT FURTHER NORTH WITH BETTER THETA E ADVECTION INTO IOWA. WILL LEAVE POPS IN EXTREME NORTH SATURDAY NIGHT. MAIN SHOW SHOULD TAKE PLACE SUNDAY NIGHT AND MONDAY AS A STRONGER WAVE MOVES TOWARD AREA. SHOULD BE ABLE TO PUSH FRONT SOUTH THROUGH REGION ON MONDAY...WITH A CHANCE OF STORMS FOR THE ENTIRE REGION AND A BREAK IN THE HIGHER HEAT INDICES. PC 1037 AM... AFTER EXAMINATION OF THE MEDIUM RANGE MODELS THIS MORNING, UPDATES HAVE BEEN MADE TO THE FORECAST FOR NEXT WEEK. CONSENSUS BETWEEN OMAHA, TOPEKA, AND THE HPC WAS TO RAISE TEMPERATURES SIGNIFICANTLY FOR THE MIDDLE TO LATTER PART OF THE WEEK. AFTER TUESDAYS FRONTAL PASSAGE THE WESTERLIES WILL ONCE AGAIN MIGRATE NORTH INTO THE DAKOTAS WITH UPPER RIDGING CONTROLLING THE SOUTHERN HALF OF THE UNITED STATES. THIS TYPE OF WEATHER PATTERN THIS TIME OF YEAR MEANS HOT, HOT, HOT. 850MB TEMPERATURES FROM THE MRF AND ECMWF RISE INTO THE 20 TO 24 RANGE FOR EASTERN KANSAS AND WESTERN MISSOURI BY WEDNESDAY. OVER THE LAST FEW WEEKS, 850 TEMPS IN THAT RANGE HAVE YIELDED HIGHS IN THE MIDDLE TO UPPER 90S WITH OUR SUN-BAKED GROUND. MRF MOS HAS BEEN CONSISTENTLY TOO COOL THIS SUMMER, SO I FEEL CONFIDENT GOING 8-10 DEGREES ABOVE GUIDANCE FOR WEDNESDAY THROUGH FRIDAY NEXT WEEK. THE EXTENDED WILL BE DRY WITH THE STORM TRACK OVER NORTHERN PLAINS. KOCH 918 AM... DOING A QUICK REVISION TO THE ZONE FORECAST PACKAGE TO BETTER REFLECT END OF PRECIPITATION AT THIS TIME BUT POSSIBILITY OF REDEVELOPMENT LATE MORNING INTO AFTERNOON INTO NORTHWEST PART OF MISSOURI AND EXTREME NORTHEAST KANSAS AS STORMS IN NEBRASKA AND NORTH CENTRAL KANSAS MOVE TOWARD AREA. ALSO MINOR TWEAKS IN THE TEMPERATURE...WIND AND DEWPOINT TRENDS IN THE RTP PRODUCT BASED ON CURRENT TRENDS. PC 454 AM... ...HEAT ADVISORY FOR MUCH OF WESTERN AND CENTRAL MISSOURI AND EASTERN KANSAS THROUGH SUNDAY... MAIN FORECAST PROBLEM IS TEMPS OVER THE WEEKEND. EXPECT THIS MORNINGS CONVECTIVE COMPLEX TO CONTINUE TO MOVE EAST AND DIMINISH IN AREAL COVERAGE ACROSS THE FORECAST AREA. CONVECTIVE DEBRIS CLOUDS WILL ALSO CONTINUE TO MOVE EAST. WELL DEFINED OUTFLOW CURRENTLY EXTENDS FROM NORTHEAST MISSOURI ACROSS THE KANSAS CITY METRO AREA. THE OUTFLOW BOUNDARY SHOULD PUSH BACK NORTH DURING THE DAY TODAY ON INCREASING SOUTH/SOUTHWEST WINDS. AND THIS MORNINGS RAIN SHOULD DO LITTLE MORE THAN ADD TO THE HUMIDITY. ANOTHER SHORTWAVE IS PROGGED TO MOVE ACROSS THE REGION TONIGHT. EXPECT A SIMILAR SCENARIO AS THIS MORNING. HAVE THEREFORE MAINTAINED POPS ACROSS THE NORTH. HOWEVER HAVE KEPT POPS LOW. BEST LIFT MAY ACTUALLY BE JUST TO THE NORTH OF THE FORECAST AREA...AS WARM FRONT LIFTS NORTH. AS WARM FRONT PUSHES NORTH...850MB TEMPS ARE PROGGED TO INCREASE FROM 20-24C YESTERDAY TO 22-26C TODAY AND PERSIST THROUGH SUNDAY EVENING. HAVE ISSUED HEAT ADVISORY FOR ADDITIONAL COUNTIES IN CENTRAL MISSOURI WITH HIGHS IN THE MID AND UPPER 90S AND DEW POINTS IN THE LOW 70S. HAVE ALSO EXTENDED ADVISORY THROUGH SUNDAY EVENING. A BREAK IN THE HEAT WILL OCCUR ON MONDAY AS A WEAK COLD FRONT PUSHES THROUGH THE REGION SUNDAY NIGHT AND MONDAY. REMAINDER OF FORECAST IS STILL ON TRACK WITH TEMPERATURES AROUND NORMAL NEXT WEEK.
