What was reported inside it

Time	Report	Where	Remark

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 Jul 20, 3:47 PM CDT, 6 hours 19 minutes earlier.

Area forecast discussion, Jul 20, 3:47 PM CDT, 6 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
347 PM CDT MON JUL 20 2009

.DISCUSSION...

DAYS 1-2...

THUNDERSTORM CHANCES TONIGHT AND TEMPERATURES THROUGH WEDNESDAY
WILL BE THE MAIN FORECAST CHALLENGES.

WATER VAPOR IMAGERY AND RUC ANALYSIS SHOWING AN UPPER LEVEL 70KT
JET NOSING INTO NORTHERN KANSAS FROM WYOMING THIS AFTERNOON AS AN
ASSOCIATED MID LEVEL SHORTWAVE DIVES SOUTHEAST THROUGH THE
NORTHERN PLAINS. AT THE SURFACE...THE WARM FRONTAL BOUNDARY HAD
SHIFTED NORTHEAST THROUGH THE DAY AND EXTENDED FROM A WEAK LOW
NEAR HILL CITY TO NEAR MEDICINE LODGE. A SURFACE TROUGH EXTENDED
SOUTH ACROSS FAR WEST KANSAS FROM SCOTT CITY TO LIBERAL. THE BEST
AXIS OF LOW LEVEL MOISTURE WAS OVER SOUTH CENTRAL AND SOUTHEAST
KANSAS INTO CENTRAL AND WESTERN NEBRASKA TO THE EAST OF THE WARM
FRONT. WIDELY SCATTERED TO ISOLATED THUNDERSTORMS WERE BREAKING
OUT OVER WESTERN NEBRASKA WHILE SOME ISOLATED STORMS WERE TRYING
TO DEVELOP OFF THE FRONT RANGE.

THINK THAT THE GOING FORECAST STILL HAS THE RIGHT IDEA THAT THE
BEST THUNDERSTORM CHANCES WILL BE IN THE NORTHEAST AND EASTERN CWA
GIVEN THE LOCATION OF THE SURFACE LOW AND WARM FRONT. MODEL SOUNDINGS
FROM THE NAM ARE SHOWING 1000-1200 J/KG OF CAPE AROUND DODGE CITY
WITH HIGHER CAPE VALUES IN THE EAST AND LOWER IN THE WEST. SOME
SHEAR INDICATED IN THE MID LEVELS WHICH COULD GET SOME OF THE STORMS
TO SPINNING. WILL CONTINUE THE MENTION OF STRONG THUNDERSTORMS AT
LEAST OVER THE EASTERN PART OF THE CWA THIS EVENING. WILL KEEP
LIKELY POPS GOING IN THE EAST THIS EVENING...TAPERING OFF TO
CHANCE/SLIGHT CHANCE IN THE SOUTHWEST CORNER.

THE MODELS SHOW THE MID LEVEL WAVE MOVING INTO THE UPPER MIDWEST
AND MISSISSIPPI VALLEY ON TUESDAY. THE COLD FRONT WILL PUSH
THROUGH ALL OF SOUTHWEST KANSAS LATER TONIGHT WITH HIGH PRESSURE
SETTLING INTO THE REGION ON TUESDAY. THERE COULD BE SOME POST FRONTAL
STRATUS ACROSS PARTS OF THE AREA GIVEN THE HIGHER DEWPOINTS IN THE
EASTERN CWA BUT THINK THAT WE SHOULD BE CLEARING OUT FAIRLY
QUICKLY AFTER SUNRISE AS MID LEVEL SUBSIDENCE AND DRIER AIR MOVES
IN. I DID BACK OFF ON TUESDAYS HIGH TEMPERATURES A FEW DEGREES IN
SOME AREAS BASED ON MODEL SOUNDINGS AND THE COOLER UPSLOPE FLOW.
ANY STORMS THAT DEVELOP WILL BE ALONG THE FRONT RANGE AND WILL NOT
LIKELY GET AS FAR EAST AS WESTERN KANSAS. ON WEDNESDAY WE SHOULD
SEE SURFACE LOW PRESSURE REDEVELOPING OVER THE HIGH PLAINS OF
EASTERN COLORADO. WEDNESDAYS HIGH TEMPERATURES SHOULD BE BACK UP
INTO THE UPPER 80S TO AROUND 90.

DAYS 3-7...

AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BE ENTRENCHED ACROSS THE
WESTERN CONUS TO BEGIN THE PERIOD THURSDAY AND WILL INFLUENCE A
NORTHWESTERLY FLOW ALOFT ACROSS WESTERN KANSAS. MEDIUM RANGE MODELS
ARE IN FAIR AGREEMENT INDICATING THE UPPER LEVEL RIDGE REMAINING IN
PLACE ACROSS THE GREAT BASIN AND FOUR CORNERS REGION THROUGH THE
WEEKEND. THIS WILL CONTINUE THE NORTHWESTERLY FLOW ALOFT ACROSS
WESTERN KANSAS THROUGH THE PERIOD AS WELL. MEANWHILE, A SERIES OF
SUBTLE UPPER LEVEL S/WAVE TROUGHS WILL CONTINUE TO CREST THE UPPER
LEVEL RIDGE OVER THE ROCKIES AND CYCLE DOWN THE NORTHWEST FLOW
ACROSS THE CENTRAL PLAINS. AT THE SURFACE,  A LEE SIDE TROUGH OF LOW
PRESSURE WILL DEVELOP IN EASTERN COLORADO EARLY IN THE PERIOD
PROVIDING A LOW LEVEL SOUTHERLY FLOW ACROSS SOUTHWEST KANSAS THROUGH
SATURDAY. COMBINED WITH THE NORTHWESTERLY FLOW ALOFT AND AMPLE LOW
LEVEL MOISTURE PRESENT, THIS WILL PRESENT THE POSSIBILITY FOR
THUNDERSTORMS ACROSS PORTIONS OF WESTERN KANSAS NEARLY EACH DAY OF
THE PERIOD.

THE CHANCE FOR PRECIP LOOKS TO CONTINUE SATURDAY INTO EARLY SUNDAY
AS BOTH THE GFS AND ECMWF SHOW AN UPPER LEVEL TROUGH OF LOW PRESSURE
IN SOUTHERN CANADA SINKING SOUTHEAST INTO THE GREAT LAKES REGION.
THIS WILL HELP MOVE AN ATTENDANT COLD FRONT SOUTH INTO WESTERN
KANSAS DURING THE SATURDAY TO EARLY SUNDAY TIME FRAME. WILL CONTINUE
WITH SLIGHT POPS THROUGH THE END OF THE WEEK DUE TO THE UNCERTAINTY
IN THE TIMING OF THE S/WAVES MOVING THROUGH AND THE MARGINALLY WEAK
FLOW ALOFT. ANY STORM DEVELOPMENT SHOULD BE DIURNALLY DRIVEN SO
EXPECT ANY STORM DEVELOPMENT TO TAKE  PLACE FROM LATE IN THE
AFTERNOON AND INTO THE OVERNIGHT HOURS THURSDAY AND FRIDAY. EVEN
THOUGH A BETTER CHANCE FOR PRECIP EXISTS SATURDAY INTO SUNDAY AS THE
COLD FRONT MOVES SOUTH INTO THE AREA, THE TIMING AND POSITIONING OF
THE FRONT REMAINS A CHALLENGE. WILL CONTINUE WITH SLIGHT POPS DURING
THE WEEKEND MAINLY DUE TO THIS REASON.

TEMPERATURES WILL REMAIN NEAR NORMAL THROUGH THE WEEKEND. FOR
THURSDAY, TEMPERATURES WILL BE FAIRLY WARM WITH THE HELP OF A LOW
LEVEL SOUTHERLY FLOW ACROSS SOUTHWEST KANSAS. THE GFS AND ECMWF SHOW
TEMPERATURES AT H85 RANGING FROM AROUND THE MID 20S(C) ACROSS
EASTERN PORTIONS OF THE CWA TO NEAR 30C ALONG THE COLORADO BORDER.
EXPECT HIGHS MAINLY IN THE 90S(F) THURSDAY WITH A GRADUAL WARMING
TREND INTO FRIDAY. HIGHS WILL RELAX A BIT SATURDAY AND FALLING JUST
BELOW NORMAL SUNDAY IN WAKE OF THE FROPA BEFORE A GENERAL WARMING
TREND RE-ESTABLISHES ACROSS WESTERN KANSAS EARLY NEXT WEEK. PLAN NO
SIGNIFICANT CHANGES TO TEMPERATURES.

&&

AVIATION...

A COLD FRONT WILL MOVE SOUTH INTO WESTERN KANSAS EARLY THIS EVENING
BRINGING THE POSSIBILITY FOR THUNDERSTORMS ACROSS PORTIONS OF
WESTERN KANSAS TONIGHT. SOME STORMS COULD BECOME SEVERE. MVFR/IFR
CONDITIONS ARE POSSIBLE IN THE VICINITY OF ALL TAF SITES IN
CONJUNCTION WITH ANY CONVECTIVE DEVELOPMENT. THE DEVELOPMENT OF LOW
LEVEL STRATUS WILL BE POSSIBLE LATE TONIGHT...MAINLY AFTER
06Z...ALONG AND BEHIND THE FRONTAL BOUNDARY AS IT PUSHES THROUGH THE
FORECAST AREA. VFR CONDITIONS ARE EXPECTED TO PREVAIL AGAIN BY LATE
TUESDAY MORNING.
