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

Dodge City, (KDDC), launched 00:00Z, 3.4 hours before the alert went out and 39 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
NATIONAL WEATHER SERVICE DODGE CITY KS
305 PM CDT MON JUN 21 2010

.DISCUSSION...

DAYS 1-2...

OUTFLOW BOUNDARY WHICH EXTENDED FROM WEST TO EAST ACROSS OUR NRN
CWA EARLIER TODAY WAS MORE DIFFICULT TO PICK OUT FROM SFC DATA
THIS AFTERNOON. BASE ON SFC OBS/SAT AND RADAR LOOP IT STILL
APPEARS TO EXTEND FROM LACROSSE TO NEAR SCOTT CITY WITH A MOIST UP
SLOPE FLOW STILL PRESENT OVER NE CO. SPC MESO PAGE INDICATING
2-3000J/KG WAS ALREADY IN PLACE IN THIS REGION AS THE NOISE OF A
25H JET WHICH WAS LOCATED NEAR THE 4 CORNERS REGION AT 12Z MON
MOVES INTO ERN CO.

FOR THIS EVENING...LATE DAY HEATING SHOULD CONTINUE TO ERODE CAP
AND GIVEN THE SHEAR AND INSTAB ALOFT AHEAD OF THIS JET SOME STRONG
TO SEVERE STORMS STILL LOOK POSSIBLE EARLY THIS EVENING. WILL
THEREFORE RAISE POPS IN OUR NW/NRN CWA EARLY AND INSERT MENTION OF
SEVERE WORDING NORTH OF GCK TO LACROSSE. HWO STILL OUTLINES THIS
AREA OF CONCERN FAIRLY WELL SO NO UPDATES NEEDED AT THIS TIME. LOW
LVL MOISTURE AXIS AND MID LVL BAROCLINIC ZONE AT 19Z DOES SUGGEST
ANY ORGANIZED CONVECTION THAT DOES DEVELOP IN NE CO LATER THIS
EVENING MAY INDEED STAY JUST NORTH OF I70 SO ALTHOUGH WILL KEEP
MENTION OF POPS GOING FOR OUR FAR NORTHERN CWA LATE TONIGHT WILL
LEAVE THE REMAINDER OF THE CWA DRY.

TUESDAY APPEARS TO BE ANOTHER HOT DAY FOR MUCH OF THE CWA. 85H
MIXDOWN TEMPS AT 00Z WED SUGGEST HIGHS RANGING FROM 100-NEAR 103.
ANY RAIN WHICH FALLS OVERNIGHT HOWEVER IS EXPECTED RESULT IN
KEEPING TEMPS SEVERAL DEGREES COOLER THAN THIS. PREVIOUS FORECAST
HAS A DECENT HANDLE WITH THIS SO NOT ANTICIPATING ANY MAJOR
ADJUSTMENTS TO THE PREVIOUS TEMP GRIDS.

AS FOR PCPN CHANCES LATE TUESDAY/TUESDAY NIGHT...WILL FOCUS ANY
POPS ALONG LEE TROF AND COLD FRONT AS 25H JET MOVES ACROSS NE CO
INTO THE NRN PLAINS. RIGHT ENTRANCE REGION OF THE JET WILL BE NEAR
OUR NW/NRN CWA EARLY SO UNABLE TO COMPLETELY RULE OUT A LATE DAY
STORM. BETTER CHANCES FOR ORGANIZED CONVECTION HOWEVER SHOULD BE
FURTHER NORTH WHERE THE MID LVL BAROCLINIC ZONE, UPPER LVL
DYNAMICS AND BETTER INSTAB/SHEAR WILL BE LOCATED. WILL THEREFORE
NOT GET TOO CARRIED AWAY WITH POPS TUESDAY NIGHT AS THIS FRONT
STARTS TO MOVE S/SE INTO THE CWA WHERE WARMER 7H TEMPS WILL BE
LOCATED LATER TUESDAY NIGHT.

ON WEDNESDAY...THE 25H JET BEGINS EXITS THE NRN PLAINS AND MOVE
INTO THE WRN GREAT LAKES REGION AS THE COLD FRONT WILL CONTINUES
TO WORK ITS WAY SOUTH ACROSS THE REMAINDER OF THE CWA. GIVEN THE
WARM EML PROGGED TO REMAIN IN PLACE AM LEANING TOWARDS KEEPING THE
FROPA MAINLY DRY WITH THE POSSIBLY EXCEPTION OF OUR NE/ERN MOST
CWA. BY 00Z THURSDAY ALL THE MODELS ARE IN GENERALLY GOOD
AGREEMENT WITH PLACING THIS FRONT IN OR NEAR OUR SE CWA AS 925-85H
FGEN IMPROVES AND 7H TEMPS COOL. GIVEN THIS ALONG WITH PROGED MU
CAPES BETWEEN 2500-3500 J/KG AND 0-6KM SHEAR OF 20-30KTS FROM THE
NAM AND GFS WILL RETAIN INCREASING POPS NORTH OF THE COLD FRONT
AFTER 21Z WHICH IS PROGGED TO BE LOCATED NEAR THE OK/KS BORDER.

DAYS 3-7...

THE MODELS ALL SHOW THAT A LONG WAVE RIDGE ALOFT WILL REMAIN
ENTRENCHED OVER THE MIDDLE OF THE U.S. IN SOME FORM THROUGHOUT THE
EXTENDED. THE FLOW TURNS BACK TO THE SOUTH AGAIN THU AS THE UPPER
RIDGE REBOUNDS AND WED'S FRONT RETREATS BACK NORTHWARD. THIS WILL
LEAD TO INCREASING TEMPS ONCE AGAIN ON THU WITH HIGH TEMPS BACK INTO
THE U90S TO N100 FRI THROUGH AT LEAST SAT.

WILL NEED TO MAINTAIN THUNDERSTORMS IN THE FORECAST THU BOTH WITH
THE WARM FRONT AS IT LIFTS THROUGH AND THEN IN THE NORTH THU NIGHT
AS ANOTHER MCS IS POSSIBLE OVER ERN CO, NE, AND NRN KS. BY FRI, THE
EML EXTENDS OUT INTO THE PLAINS AS THE RIDGE MOVES OHD. THIS SHOULD
PRECLUDE THUNDERSTORMS AND THUS POPS REMAIN NIL. THE NEXT SHORTWAVE
FLATTENS THE RIDGE ON SAT AND PUSHES ANOTHER FRONT INTO NRN KS. IT
IS TOO EARLY TO SAY HOW STRONG THIS SYSTEM WILL BE BUT THE FRONT
LOOKS LIKE IT WILL BE ABLE TO MOVE WELL SOUTH THROUGH KS, PERHAPS
EVEN REACHING THE KS/OK BORDER SAT NIGHT.

THE FORECAST FOR SUN/MON DEPENDS A LOT ON THE POSITION/STRENGTH OF
THIS FRONT AND THE MODELS ARE ALL REASONABLY CONSISTENT IN KEEPING
THE FRONT OVER WRN KS INTO SUN AND THEN BEGIN TO LIFT IT BACK NORTH
LATE MON. THE OTHER CONSIDERATION WORTH WATCHING IS WITH THE LOWER
HEIGHTS, THERE MAY BE MORE OF AN OPPORTUNITY FOR NOCTURNAL MCS
ACTIVITY FURTHER SOUTH THAN WHAT WE HAVE BEEN SEEING AS OF LATE. IT
SEEMS PRUDENT TO HAVE SOME POPS UNDER THIS SCENARIO, THUS WILL BE
INSERTING AT LEAST SLIGHT CHC POPS IN DURING THE PERIOD. THE TEMP
FORECAST IS PROBLEMATIC FOR SUN AND MON AND DEPENDS LARGELY ON THE
FRONT AND NIGHT TIME MCSS. IF THE FRONT LINGERS AS SUGGESTED BY THE
MAJORITY OF THE MODELS, AND/OR MCS ACTIVITY IS ENHANCED, TEMPS COULD
BE MUCH LOWER THAN THE CURRENT FCST SUGGESTS. WILL NUDGE TEMPS DOWN
A BIT ON SUN AND MON. -WRIGHT

.AVIATION...

VFR CONDS EXPECTED AT ALL TERMINALS THROUGH AT LEAST 21/23Z.
SHRA/TS ARE EXPECTED TO FORM ALONG A PRESSURE TROF/FRONT
STRETCHING FROM WEST-CENTRAL KS EASTWARD INTO NE KS AFTER 21/23Z
AND THEN EVOLVE INTO A MCS AND MOVE TO THE NE OVERNIGHT. HAVE
INCLUDED VCTS IN ALL TAFS BUT KGCK/KHYS ARE MOST LIKELY TO BE
AFFECTED BY THESE STORMS WITH POSSIBLE IFR CONDS AT TIMES THROUGH
22/10Z. -WRIGHT
