AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
325 PM CDT FRI JUL 22 2011

.SYNOPSIS...

A FAIRLY IMPRESSIVE UPPER LEVEL TROUGH WAS LOCATED OVER THE CANADIAN
ROCKIES THIS AFTERNOON.  THE MID LEVEL PV ANOMALY TIED TO THIS
SYSTEM WAS PIVOTING NORTHEAST FROM THE CHIMNEY OF IDAHO INTO
NORTHWESTERN MONTANA RESULTING IN A DECENT PRESSURE FALL FIELD OVER
CENTRAL MONTANA.  THIS IS ABOUT THE EXTENT OF EXCITEMENT ON THE
SYNOPTIC SCALE.  CLOSER TO WESTERN KANSAS...A PLUME OF 500-700MB
CONTINUED FROM NEW MEXICO NORTHEAST THROUGH WESTERN KANSAS AND INTO
SOUTHERN/EASTERN NEBRASKA TO IOWA.  BY MID AFTERNOON...MOISTURE WAS
SLOWLY MIXING OUT ACROSS THE CENTRAL AND NORTHWESTERN SECTIONS OF
THE FORECAST AREA AS REMNANT WEAK OUTFLOW BOUNDARIES AND LATENT HEAT
FLUXES FROM EVAPORATION (IN THE NORTHWESTERN COUNTIES WHERE IT
RAINED) WERE LOSING THEIR STEAM WITH CONTINUED INTENSE LATE JULY
INSOLATION.  A DEEP CUMULUS FIELD WAS DEVELOPING ACROSS THE CENTRAL
SECTIONS OF THE FORECAST AREA WHERE DEEP MIXING WAS UNDERWAY AND A
FEW INCIPIENT...BUT VERY SMALL ECHOES COULD BE FOUND ON RADAR NEAR
THE OKLAHOMA-KANSAS BORDER NEAR COLDWATER TO BUTTERMILK.

&&

.DISCUSSION...

DAYS 1-2...

THE CUMULUS FIELD WILL CONTINUE TO EVOLVE THROUGH THE LATE AFTERNOON
HOURS WITH DEVELOPMENT OF ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS...JUST ABOUT ANYWHERE ACROSS THE DDC FORECAST AREA.
WILL BROADBRUSH THE AREA WITH 20 POPS BUT STILL THINK THE BEST
CHANCE...WHERE 30-40 POPS EXIST...WILL BE ACROSS NORTHERN SECTIONS
OF THE FORECAST AREA IN THE VICINITY OF LAST NIGHTS CONVECTIVE
EPISODE.  A SMALL MESOSCALE CONVECTIVE SYSTEM (MCS) MAY EVOLVE IN
THE SAME GENERAL LOCATION AS LAST NIGHT...WHICH IS THE REASON FOR
THE 30-40 POPS GENERALLY ALONG AND NORTHWEST OF A JOHNSON TO GARDEN
CITY TO NESS CITY LINE.  TOMORROW...REMNANT OUTFLOW BOUNDARIES WILL
WASH OUT BY LATE MORNING GIVING WAY TO BROAD SOUTHERLY FLOW
RESPONDING TO THE SYNOPTIC SCALE LEE TROUGH.  FRONTOGENESIS WILL
INCREASE BY AFTERNOON/EVENING TOMORROW FROM EAST CENTRAL/SOUTHEAST
COLORADO...NORTHEASTWARD THROUGH NORTHWEST KANSAS INTO CENTRAL
NEBRASKA.  THIS WILL BE THE PREFERRED AREA FOR ORGANIZED
THUNDERSTORM DEVELOPMENT LATE IN THE DAY.  WILL AGAIN BE GOING WITH
30 TO 40 POPS ACROSS MAINLY THE NORTHERN/NORTHWESTERN SECTIONS OF
THE FORECAST AREA LATE SATURDAY AFTERNOON/SATURDAY NIGHT AS A MORE
ORGANIZED MCS SHOULD EVOLVE THROUGH THE LATE EVENING AND OVERNIGHT
HOURS.  AS FAR AS THE EXCESSIVE HEAT IS CONCERNED...PERSISTENCE IS
THE FORECAST METHOD OF CHOICE HERE...AND AM NOT EXPECTING MUCH
DEVIATION FROM THE TODAYS TEMPERATURES...AND AS A RESULT WILL KEEP
THE EXCESSIVE HEAT WARNING GOING FOR ONE MORE DAY TOMORROW OVER THE
FAR EASTERN COUNTIES (FROM HAYS SOUTH TO STAFFORD TO MEDICINE
LODGE).  ON SUNDAY...THE SYNOPTIC FRONT TIED TO THE SIGNIFICANT
SHORTWAVE TROUGH (AS DISCUSSED IN THE SYNOPSIS) WILL BE OVER
PORTIONS OF THE FORECAST AREA DURING THE DAY...MOST LIKELY ALONG THE
ARKANSAS RIVER.  THE FRONT WILL MOST LIKELY STALL OUT GIVEN THE
ABSENCE OF CONTINUED PRESSURE RISES FROM THE HIGH TO THE NORTH AS
THE STORM SYSTEM RESPONSIBLE MOVES QUICKLY OFF INTO THE GREAT LAKES
REGION AND UPPER LEVEL HIGH PRESSURE BUILDS BACK IN TO THE CENTRAL
PLAINS.  WILL BE GOING WITH 20 TO 30 POPS ALONG AND NORTH OF THE
ARKANSAS RIVER LATE DAY SUNDAY INTO SUNDAY EVENING ALONG THIS
WEAKENING FRONT...AND A BRIEF BREAK FROM THE 100-DEGREE HEAT ACROSS
MOST OF THE AREA (EXCEPT PERHAPS FOR ALONG THE OKLAHOMA BORDER).

DAYS 3-7...

THE FRONTAL BOUNDARY MENTIONED IN THE SHORT TERM WILL LIFT NORTH AS
A WARM FRONT ON MONDAY. BEFORE THEN A FEW THUNDERSTORMS WILL BE
POSSIBLE ACROSS NORTHERN AND WESTERN KANSAS EARLY MONDAY MORNING.
HIGHS ON MONDAY ARE PROGGED TO ONCE AGAIN RISE INTO THE LOWER 100S
ACROSS EASTERN PORTIONS OF THE CWA WITH UPPER 90S ELSEWHERE. I
ALSO HAVE PLACED A SLIGHT CHANCE OF THUNDERSTORMS IN THE GRIDS FOR
MONDAY NIGHT DUE TO THE SIMILAR CHARACTERISTICS OF THE FRONT THAT
STALLED OUT ACROSS NORTHERN KANSAS LAST NIGHT AND THE EXPECTED
THUNDERSTORMS TONIGHT.

HIGH PRESSURE WILL THEN MOVE BACK INTO THE AREA TUESDAY AND
WEDNESDAY. MODELS SHOW TEMPERATURES IN THE MID LAYERS TO BE WARM AND
HAVE KEPT CHANCES OF CONVECTION OUT OF THE GRIDS. HIGHS IN THE MID
100S ARE EXPECTED ON TUESDAY AND WEDNESDAY WITH LOWS IN THE 70S. IN
FACT...THE FAR EAST FA MAY AGAIN FLIRT WITH HEAT ADVISORY CONDITIONS
WITH HEAT INDICES NEAR 105. BREEZY CONDITIONS ARE ALSO ANTICIPATED
TUESDAY AND WEDNESDAY ALONG WITH THE HEAT.

THE NEXT UPPER LEVEL TROUGH IS EXPECTED TO MOVE THROUGH THE NORTHERN
PLAINS WEDNESDAY NIGHT INTO FRIDAY. THIS WILL PUSH ANOTHER COLD
FRONT DOWN FROM THE NORTHERN PLAINS AND POSITION ITSELF CLOSE TO OUR
AREA BY THURSDAY MORNING. CONFIDENCE IS LOW ON HOW FAR SOUTH THIS
FRONT WILL TREK BEFORE STALLING OUT. THE NAM HAS IT PUSHING THROUGH
OUR AREA WHERE AS THE GFS AND ECMWF HAVE IT STALLING OUT ACROSS
CENTRAL KANSAS. I HAVE WENT WITH PERSISTENCE HAVING THE FRONT
STALLING OUT ACROSS NORTHERN PORTIONS OF OUR CWA LIKE THE LAST
COUPLE OF FRONTS HAVE DONE. I HAVE PLACED A SLIGHT CHANCE OF
THUNDERSTORMS ACROSS NORTHERN PORTIONS OF OUR FORECAST AREA BUT THIS
MAY HAVE TO BE CHANGED IF FUTURE MODEL RUNS LOOK TO PUSH THE FRONT
THROUGH OUR AREA. I HAVE ALSO LOWERED HIGH TEMPERATURES SLIGHTLY ON
THURSDAY AND FRIDAY SINCE MODELS HAVE SHOWN A DOWNWARD TREND.

&&

.AVIATION...

A FEW THUNDERSTORMS MAY FORM THIS EVENING ACROSS THE AREA TERMINALS
BRINGING BRIEF MVFR CONDITIONS DUE TO LOWERED VISIBILITY. OTHERWISE
VFR CONDITIONS WILL PREVAIL. WINDS WILL GENERALLY BE FROM THE SOUTH
AT 10 TO 15 KNOTS WITH THE EXCEPTION OF AREAS CLOSE TO CONVECTION
WHERE OUTFLOW BOUNDARIES COULD INCREASE THE SPEED AND DIRECTION OF
THE WIND.
