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 23, 3:29 PM CDT, 3 hours 12 minutes earlier.

Area forecast discussion, Jul 23, 3:29 PM CDT, 3 hours 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
329 PM CDT FRI JUL 23 2010

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST CHALLENGES ARE CHANCES FOR THUNDERSTORMS WEST
TONIGHT THEN MORE CHANCES OF THUNDERSTORMS WITH HEAVY RAINFALL AND
LOCALIZED FLOODING ASSOCIATED WITH THE COLD FRONT ON SATURDAY INTO
SUNDAY.

A NORTHERN BRANCH SHORTWAVE TROUGH IN THE DAKOTAS WILL MOVE INTO THE
UPPER MIDWEST BY MORNING INTO THE AFTERNOON. THIS FEATURE WILL PUSH
A COLD FRONT TO JUST NORTH OF THE FA BY MORNING AND THROUGH MUCH OF
THE FA BY SATURDAY LATE AFTERNOON AND EVENING. A FEW THUNDERSTORMS
ARE EXPECTED AHEAD OF THE COLD FRONT TONIGHT ALONG A TROUGH LINE IN
FAR WESTERN KANSAS. THUNDERSTORMS ARE THEN EXPECTED TO BECOME MORE
NUMEROUS SATURDAY AFTERNOON INTO SUNDAY WITH THE COLD FRONT SATURDAY
AND THEN ISENTROPIC LIFT BEHIND THE FRONT SATURDAY NIGHT AND SUNDAY.
ALSO NEARLY 2 INCHES OF PRECIPITABLE WATER ARE ON THE FORECAST
SOUNDINGS WITH TROPICAL MOISTURE IN PLACE AND RIGHT REAR QUAD OF
UPPER LEVEL JET. MODELS FORECASTING SOME 1 TO 3 INCHES QPF MAINLY
FROM AROUND DODGE CITY SOUTH AND THIS IS CLOSE TO CURRENT NCEP
GUIDANCE. COULD HAVE SOME LOCALIZED FLOODING IF ALL OF THIS COMES
INTO PLACE LIKE GUIDANCE SUGGESTS. HAVE UPPED POPS WITH ANTICIPATED
EVOLUTION.

AS FOR TEMPS WILL KEEP OVERNIGHT LOWS AROUND 70 WEST TO THE MID 70S
EAST. ON SATURDAY WITH EXPECTED MOSTLY CLOUDY SKIES WILL LOWER HIGHS
TO AROUND 90 NORTH AND CENTRAL FA TO MID 90S SOUTHEAST. ON SATURDAY
NIGHT LOOK FOR A BIT COOLER OVERNIGHT LOWS IN THE MID 60S TO AROUND
70. THEN FOR SUNDAY HIGHS SHOULD BE AGAIN TEMPERED BY LOTS OF CLOUDS
AND STORMS.

DAYS 3-7...

MEDIUM RANGE MODELS REMAIN IN GENERAL AGREEMENT INDICATING AN UPPER
LEVEL RIDGE OF HIGH PRESSURE BEGINNING TO SLOWLY BUILD BACK IN
ACROSS THE CENTRAL PLAINS EARLY IN THE WEEK AND PREVAILING THROUGH
THE END OF THE PERIOD. AS A RESULT, SHOULD EXPECT DRIER CONDITIONS
ACROSS WESTERN KANSAS DURING MUCH OF THIS TIME FRAME. HOWEVER, THE
GFS AND ECMWF SEEM TO HAVE A DECENT HANDLE ON AN UPPER LEVEL TROUGH
TRANSITIONING EAST ACROSS THE WESTERN HIGH PLAINS LATE IN THE WEEK
BRINGING THE NEXT CHANCE FOR APPRECIABLE RAINFALL TO THE AREA.
BECAUSE OF THIS, WILL INTRODUCE SLIGHT POPS FOR LATE THURSDAY
THROUGH FRIDAY. HIGH TEMPERATURES ARE EXPECTED TO BE NEAR SEASONAL
MONDAY AS A NEAR STATIONARY FRONTAL BOUNDARY IS PROJECTED TO LIFT
NORTH ACROSS WESTERN KANSAS DURING THE DAY. THE GFS AND ECMWF SHOW
H85 TEMPERATURES RANGING FROM THE LOW 20S(C) ACROSS EASTERN PORTIONS
OF THE CWA TO THE MID 20S(C) ALONG THE COLORADO BORDER. THIS WILL
RESULT IN HIGHS CLIMBING WELL BACK UP INTO THE 90S(F) ON MONDAY. AS
UPPER LEVEL RIDGING CONTINUES TO BUILD INTO THE AREA, LEE SIDE
TROUGHING WILL DEVELOP HELPING TO CONTINUE A LOW LEVEL SOUTHERLY
FLOW INTO THE REGION AND ALLOWING TEMPERATURES TO REMAIN NEAR NORMAL
THROUGH AT LEAST THURSDAY. WILL MAKE ONLY MINOR ADJUSTMENTS TO
TEMPERATURES DURING THE PERIOD.

&&

.AVIATION...

A LEE SIDE TROUGH OF LOW PRESSURE EXTENDING FROM NORTHWESTERN KANSAS
DOWN INTO NORTHEASTERN NEW MEXICO WILL MOVE VERY LITTLE DURING THE
PERIOD. ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL BE POSSIBLE
AGAIN THIS EVENING ALONG AND JUST AHEAD OF THE TROUGH...PRIMARILY
WEST OF A KHYS TO KDDC LINE. VFR CONDITIONS ARE EXPECTED THROUGH
LATE SATURDAY MORNING EXCEPT IN AND AROUND ANY POTENTIAL CONVECTION.
WINDS WILL BE SOUTHERLY AND GENERALLY 10 TO 20KT DURING THE PERIOD.
