What was reported inside it

Time	Report	Where	Remark
Jun 17, 6:15 PM CDT	HAIL 0.75	8 S Ft. Dodge, KS

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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.

What forecasters said that day

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

NWS Dodge City, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 17, 3:29 PM CDT, 2 hours 29 minutes earlier.

Area forecast discussion, Jun 17, 3:29 PM CDT, 2 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
329 PM CDT WED JUN 17 2009

.DISCUSSION...

DAYS 1-2...

TEMPERATURES AND THUNDERSTORM PROBABILITIES ARE THE MAIN FORECAST
CONCERNS.

THE 12Z UA ANALYSIS SHOWED A LARGE UPPER TROUGH OVER THE WESTERN
STATES. AT 250 MB AN 80 KNOT SPEED MAX WAS LOCATED OVER ARIZONA
WHILE A 130 KNOT JET WAS COMING ONSHORE OVER THE PACIFIC NORTHWEST.
SUBTLE DISTURBANCES WERE EVIDENT IN THE SOUTHWEST FLOW EAST OF THE
MAIN TROUGH. ONE DISTURBANCE HAD LIFTED FROM THE MOUNTAINS OF
NORTHERN MEXICO AND WAS CURRENTLY MOVING UP THROUGH EASTERN NEW
MEXICO AND FAR WEST TEXAS. THIS DISTURBANCE HAD HELPED FOCUS SOME
THUNDERSTORM DEVELOPMENT ALONG THE DRYLINE ALONG THE TX/NM BORDER.

FOR THIS EVENING THE MODELS PAINT SOME QPF ACROSS THE WESTERN PART
OF THE CWA. THIS SEEMS REASONABLE GIVEN THE CURRENT RADAR TRENDS
AND THE UPPER SPEED MAX LIFTING OUT INTO THE CENTRAL HIGH PLAINS
TONIGHT. WILL ADD SOME SLIGHT CHANCE TO CHANCE POPS TO THE AREA
BASICALLY WEST OF A HAYS TO DODGE CITY LINE THROUGH ABOUT 06Z.

ON THURSDAY A NORTHERN STREAM SHORTWAVE WILL BE APPROACHING THE NORTHERN
AND CENTRAL PLAINS. THE WEAKER LEAD SHORTWAVE MAY HELP VEER THE SURFACE
FLOW TO THE SOUTHWEST DURING PART OF THE DAY BUT THINK THAT WINDS SHOULD
BACK TO THE SOUTH IN THE AFTERNOON. AT ANY RATE MODEL SOUNDINGS SHOW
DECENT MIXING. WITH WARM MID LEVEL TEMPERATURES IN PLACE HIGH TEMPERATURES
SHOULD CLIMB INTO THE UPPER 90S WITH 100 DEGREE TEMPERATURES POSSIBLE
AROUND MEDICINE LODGE.

AS THE UPPER WAVE MOVES OUT THURSDAY NIGHT A COOL FRONT WILL PUSH SOUTHEAST
ACROSS WESTERN KANSAS. MODEL SOUNDINGS SHOW SOME INSTABILITY IN PLACE
AHEAD OF THE FRONT SO WILL KEEP THE CHANCE/SLIGHT CHANCE POPS INTACT.
THE LATEST MODEL RUNS HAVE THE FRONT A LITTLE SLOWER AND STILL IN THE
SOUTHEASTERN COUNTIES AT 12Z. WILL KEEP THE SMALL POPS INTO THE MORNING
HOURS THERE BUT DIMINISH BY MIDDAY. BY 00Z SATURDAY THE NAM HAS THE
FRONT STATIONARY ALONG OR JUST SOUTH OF THE OKLAHOMA BORDER WHILE THE
GFS HAS IT A LITTLE FARTHER NORTH. COULD SEE A FEW STORMS DEVELOP
ALONG THE FRONT SO WILL KEEP THE SLIGHT CHANCE POPS IN PLACE FOR
THE SOUTHEAST. GERARD

DAYS 3-7...

THE MODELS HAVE DECENT AGREEMENT IN PLACEMENT OF LARGE SCALE
SYNOPTIC FEATURES FROM AROUND FRIDAY THROUGH MONDAY. THE PATTERN MAY
BE CHARACTERIZED BY A NW PACIFIC TROUGH/JET EJECTING SHORTWAVES
ACROSS THE NORTHERN GREAT PLAINS. IN THE MEANTIME, A SUBTROPICAL
HIGH OVER THE GULF STATE BEGINS TO RETROGRADE INTO THE LOWER
MISSISSIPPI VALLEY/SOUTHERN PLAINS. THE RESULT WILL BE A REASONABLE
LIKELIHOOD OF A QUASI-STATIONARY SURFACE BOUNDARY DRAPED SOMEWHERE
FROM THE CENTRAL PLAINS STATES THROUGH THE UPPER MIDWEST UNDERGOING
FRONTOGENESIS AT TIMES, AND A FOCAL POINT FOR MCS DEVELOPMENT NORTHEAST
OF KANSAS, BUT BETTER CHANCES FOR AIRMASS-PULSE TYPE THUNDERSTORMS
FOR CENTRAL KANSAS OR ISENTROPIC FORCED ASCENT SCATTERED RAIN AND
THUNDER. THERE  NOT AS MUCH CONFIDENCE IN TIMING OF EVENTS HOWEVER.
THE MODELS INDICATE AT LEAST TWO UPPER JETS LIFTING NORTHEAST
THROUGH THE EASTERN SIDE OF THE WESTERN TROUGH, BOTH OF WHICH WOULD
PLACE SECTIONS OF THE CWA IN THE RIGHT EXIT REGION OF THE JET FOR A
PERIOD. THE MOST LIKELY TIME FRAMES AT THIS TIME APPEAR TO BE LATE
FRIDAY NIGHT THROUGH EARLY SUNDAY WHICH COULD ENHANCE THUNDERSTORM
CHANCES. TIMING AND PLACEMENT OF THE FEATURE WILL LIKELY UNDERGO
MANY CHANGES IN THE MANY MODEL RUNS TO COME THEREFORE CONFIDENCE IN
ANYTHING HIGHER THAN 20 PERCENT CHANCES AT THIS POINT WOULD BE
PREMATURE, HOWEVER MIXING MODELS OUTPUT WITH MOS GUIDANCE WOULD
WARRANT 30 TO 50 PERCENT CHANCES FOR SATURDAY IN OUT SOUTHEAST
SECTIONS.

TEMPERATURES DURING THE PERIOD WILL BE EVEN MORE PROBLEMATIC AS
CLOUD COVER WILL DRASTICALLY IMPACT TEMPERATURES ACROSS THE CENTRAL
PLAINS. MOS GUIDANCE SUGGESTS COOLER UPPER 80S AS AS MOISTURE
TRANSPORT INCREASES SATURDAY ALONG WITH CONVECTIVE CHANCES.
OVERNIGHT LOWS WILL HOWEVER WILL BE QUITE MILD WITH LOW IN THE
UPPER 60 TO NEAR OR AROUND 70 DEGREES IN THE PRATT-MEDICINE LODGE
REGIONS. RUSSELL

&&

AVIATION...

MOISTURE RICH BOUNDARY LAYER JUXTAPOSED ACROSS A WARM SURFACE FRONT
THIS AFTERNOON COULD BE THE FOCUS FOR +TSRA/CB, HOWEVER THE LIMITING
FACTOR CONSIDERED THE LAST COUPLE OF DAYS ARE THE VERY WARM 700 MB
TEMPERATURES IN THE 13-15 DEGREE RANGE. BETTER INSTABILITY IS FARTHER
NORTHEAST, SO FOR TAF FORECAST PURPOSES WILL LEAVE TERMINALS DRY AND
MONITOR FOR CONVECTIVE TRENDS AND UPDATE AS NEEDED. BOUNDARY LATER
WINDS WILL CONTINUE TO BE MODERATE AND SOUTHWESTERLY BACKING FATHER
WEST BY WEDNESDAY.
