The radar

The Wichita radar (KICT), 102 km from the middle of the area, began a volume at 16:16 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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 nearest sounding before it

Topeka, KS (KTOP), launched 12:00Z, 4.3 hours before the alert went out and 175 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION

304 AM CDT FRI SEP 17 2004

.DISCUSSION...
FCST CONCERNS...
REMOTE CNVTV CHC THIS MORNING AND AGAIN LATE TONGT, THEN TIMING OF
SGFNT FROPA NEXT WEEK...

FRI-SUN:
SOUTHEAST FLOW HAS BROUGHT LLVL MOIST AIR BACK ACROSS OKLAHOMA OVER
THE PAST 24 HOURS. SHOULD SEE SOME OF THAT MOISTURE CREEP INTO
SOUTHERN KS AS THE DAY PROGRESSES. WENT AHEAD AND INTRODUCED SOME
ISO POPS FOR ELEVATED MORNING CONVECTION TODAY, MAINLY ACROSS
CNTRL/SCNTRL KS. BEEN NOTICING SOME MID-LVL CLOUDS AND DECENT
ISENTROPIC LIFT OVER THESE AREAS. MODIFIED SOUNDINGS SHOW AN
UNSTABLE AIR MASS ALONG WITH CAPES IN EXCESS OF 2000 J/KG THIS
MORNING WITH VERY LITTLE CIN. WEAK UPPER LVL WAVE MOVING THROUGH
THE REGION AS WELL. LOCAL AREA PROFILERS SHOW GOOD VEERING OF THE
WINDS FROM LOW TO MID-LVLS. WILL LET LATER SHIFTS DECIDE IF POPS
NEED TO BE EXTENDED INTO THE AFTN.

UPPER RIDGE BEGINS TO BUILD INTO THE AREA THROUGH SAT BEFORE SLIDING
A BIT EAST ON SUN. AFTN HIGH TEMPS WILL SOAR BACK INTO THE UPPER
80S INTO THE LOWER 90S THROUGH THE WEEKEND. WILL HAVE TO MONITOR
THINGS AGAIN LATE TONIGHT WITH LLVL MOISTURE AROUND AND A MODEST
LLVL JET, COULD BE A SCHC FOR ELEVATED CONVECTION ACROSS AREAS OF
CNTRL AND SERN KS. HOWEVER, WARM TEMPS AT 700 MB COULD KEEP
CONVECTION FURTHER ACROSS FAR ERN AND NERN KS WHERE BETTER
ISENTROPIC LIFT WILL BE.

MON-THU:
NE-SW ORIENTED UPPER RIDGE AXIS REMAINS ACROSS ERN KS AS BROAD UPPER
TROUGH DEEPENS ACROSS THE WRN US. MED RANGE MODELS NOT IN GOOD
AGREEMENT FROM WED ON. THE ECM BRINGS UPPER SYSTEM FURTHER NORTH
ACROSS THE CENTRAL AND NORTHERN PLAINS, AS WELL AS QUICKER THAN THE
GFS. WILL NOT MAKE MANY CHANGES TO ONGOING EXTENDED FCST UNTIL
THINGS BECOME CLEARER. ONE THING FOR CERTAIN, IS THAT AFTN HIGH
TEMPS WILL CONTINUE TO BE SEVERAL DEGREES ABOVE NORMAL INTO
WEDNESDAY AS NEXT SYSTEM APPROACHES. TIMING OF THE SYSTEM BY
MID-WEEK WILL BE TRICKY AND COULD PLAY HAVOC WITH TEMPS TOWARD THE
LATTER HALF OF THE EXTENDED, AS COOLER AIR FILTERS IN BEHIND THE
TROUGH.
