AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
355 PM CDT SAT JUN 18 2011

.DISCUSSION...

DAYS 1-2...

A LONGWAVE TROUGH WAS SITUATED ACROSS THE WESTERN UNITED STATES
THIS AFTERNOON. ON THE FRONT SIDE OF THIS TROUGH, A WEAK SHORTWAVE
TROUGH AND ASSOCIATED COOL POOL WAS EJECTING EAST-NORTHEASTWARD ACROSS
COLORADO. ON THE BACK SIDE OF THE LONGWAVE TROUGH, A STRONG
SHORTWAVE TROUGH WAS DIGGING SOUTHEASTWARD TOWARDS THE PACIFIC
NORTHWEST. A STATIONARY FRONT WAS LOCATED ACROSS NORTHERN OKLAHOMA
WITH WEAK UPSLOPE FLOW DEVELOPING ACROSS WESTERN KANSAS. DEWPOINTS
WERE VERY HIGH IN THE WARM SECTOR ACROSS CENTRAL AND EASTERN OKLAHOMA.

THE MAIN FORECAST PROBLEM FOR TONIGHT IS THUNDERSTORM CHANCES.
CONVECTION WAS ALREADY DEVELOPING ACROSS EASTERN COLORADO THIS
AFTERNOON IN RESPONSE TO THE AFOREMENTIONED SHORTWAVE TROUGH AND
COLD POOL. LOW-LEVEL UPSLOPE FLOW WAS VERY WEAK THIS AFTERNOON
ACROSS WESTERN KANSAS. THE EDGE OF THE BETTER LOW-LEVEL MOISTURE
WAS LOCATED FROM NORTH PLATTE TO MCCOOK TO DODGE CITY AND WAS
SLOWLY EDGING WESTWARD. THE NAM SHOWS EASTERLY UPSLOPE FLOW INCREASING
DRAMATICALLY THIS EVENING TO 30KT AT 850MB ACROSS WESTERN KANSAS.
DESPITE THE WEAK WINDS THIS AFTERNOON, IF STORMS CAN HOLD TOGETHER
UNTIL EVENING, THEN THE ENVIRONMENT WOULD BE MUCH MORE FAVORABLE
FOR AN ORGANIZED CONVECTIVE CLUSTER PROGRESSING ACROSS THE CENTRAL
AND NORTHERN PART OF THE FORECAST AREA TONIGHT. THE HRRR HAS
BACKED OFF OF THE MCS SCENARIO. WITH MAINLY WESTERLY MID-LEVEL
WINDS, FEEL THAT ANY MCS COULD DEVELOP A COLD POOL AND TURN TO THE
EAST-SOUTHEAST AND AFFECT OUR FORECAST AREA. DAMAGING WINDS ARE
POSSIBLE WITH THESE STORMS. LARGE HAIL UP TO GOLFBALL SIZE IS
POSSIBLE AS THE STORMS REACH THE RICHER MOISTURE BETWEEN 00 AND 03Z.

CYCLOGENESIS WILL COMMENCE IN THE LEE OF THE COLORADO ROCKIES
BY SUNDAY MORNING. THE NAM/GFS SHOW THE FRONT OVER OKLAHOMA
PUSHING NORTH AS A WARM FRONT INTO NORTHERN KANSAS BY LATE
AFTERNOON, WITH THE DRYLINE TRAILING SOUTH FROM THE FRONT INTO
SOUTH CENTRAL KANSAS. TEMPERATURES WILL BECOME VERY HOT IMMEDIATELY
BEHIND THE DRYLINE AS THE MID-LEVEL HOT PLUME (+16C AT 700MB) PUSHES
DOWNSLOPE ONTO THE LOWER TERRAIN. SO DECIDED TO RAISE TEMPERATURES
A FEW DEGREES. ALL OF THE MODELS SHOW THE HIGH-LEVEL JET
ASSOCIATED WITH THIS SHORTWAVE TROUGH JUST TO THE NORTH OF OUR
FORECAST, AREA WITH LITTLE IN THE WAY OF LARGE SCALE ASCENT OVER
SOUTHWEST AND CENTRAL KANSAS. I FEEL THAT THE SEVERE THUNDERSTORM
THREAT WILL BE OVER FAR NORTHERN KANSAS AND SOUTHERN NEBRASKA
ALONG AND JUST NORTH OF THE WARM FRONT. THIS COINCIDES WITH THE
SPC DAY 2 MODERATE RISK. DECIDED TO UPGRADE THE FIRE WEATHER WATCH
TO A WARNING FOR THOSE COUNTIES THAT HAVE REMAINED DRY FOR THE
MOST PART OVER THE PAST FEW WEEKS. DUE TO THE HEAVY RAINS IN SEWARD AND
MEADE COUNTIES, DECIDED TO LEAVE THOSE COUNTIES OUT. WINDS COULD
REACH CLOSE TO ADVISORY CRITERIA AS MID-LEVEL MOMENTUM MIXES DOWN
FROM 600MB.

THE MAIN TROUGH AXIS WILL PASS ACROSS WESTERN KANSAS ON MONDAY. THE
DAY SHOULD GET OFF TO A VERY WARM START IN OUR SOUTHEASTERN
COUNTIES SINCE THE AFTERNOON HIGHS THERE SUNDAY WILL BE NEAR 107F,
FOLLOWED BY 20-25KT SOUTHERLY WINDS ALL NIGHT SUNDAY NIGHT. SO I DECIDED
TO COMPLETELY IGNORE MOS (USING A COMBINATION OF METEOROLOGY AND
EXPERIENCE) AND INCREASE LOW TEMPERATURES TO BETWEEN 75 AND 80F IN
OUR FAR SOUTHEAST. THIS NUMBERS ARE BARELY WITHIN THE 5F COLLABORATION
TOLERANCE. THE SURFACE COLD FRONT WILL BE ARRIVING IN DODGE CITY
AROUND MID-DAY MONDAY AND IN MEDICINE LODGE BY LATE AFTERNOON.
VERY HOT TEMPERATURES CAN AGAIN BE EXPECTED AHEAD OF THE COLD
FRONT, WITH MUCH COOLER READINGS BEHIND THE FRONT.

DAYS 3-7...

THE EXTENDED PERIOD STARTS WITH AN UPPER LOW EXITING OUR AREA,
FOLLOWED BY A PERIOD OF NORTHWESTERLY DOWNSLOPE FLOW, AND A HIGH
PRESSURE RIDGE BUILDS INTO THE EASTERN ROCKIES REGION BY FRIDAY.

AROUND THE BEGINNING OF DAY 3, OR TUESDAY AT 00Z, AN UPPER LEVEL
STORM SYSTEM WILL BE JUST ABOUT EXITING WESTERN KANSAS TO THE
NORTHEAST.  BUT THERE WILL BE STRONG SYNOPTIC LIFT ACROSS OUR
EASTERN CWA, AND 30  POPS FOR TRW- WILL COVER THAT.  THERE COULD BE
A LITTLE WRAP AROUND MOISTURE AND INSTABILITY EARLY TUESDAY, SO 20
TO 30 POPS WILL EXIST ACROSS OUR NORTH END EASTERN CWA.  RIGHT NOW,
IT IS TOO HARD TO DETERMINE IF AND WHERE ANY SEVERE STORMS WILL
OCCUR.  WITH THE PATTERN OF LATE BEING VERY WARM SURFACE CONDITIONS
AND COLD POOLS TRACKING ACROSS OUR AREA, SEVERE STORMS CAN NOT BE
RULED OUT.  IT WILL GET INCREASINGLY WARMER EACH DAY PAST TUESDAY,
STARTING IN THE MID 80S TUES, WARMING TO THE MID 80S TO LOWER 90S BY
THURSDAY, AND THE MID 90S BY SATURDAY.  A DRY LINE SHOULD BE FORMING
EACH AFTERNOON THU-SAT, SO SMALL POPS WILL BE ACROSS OUR EASTERN AND
NORTHERN SECTIONS EACH LATE AFTERNOON AND EVENING, TO COVER THE DRY
LINE INITIATION POTENTIAL.

OVERNIGHT LOWS WILL GO THROUGH A SLOW WARMING TREND, STARTING IN THE
UPPER 50S TO LOWER 60S WED, AND WARMING A FEW DEGREES EACH DAY,
REACHING THE MID 60S (NW) TO THE LOWER 70S (SE).

&&

.AVIATION...

FOR THE MOST PART, THERE WILL BE VFR CONDITIONS THROUGH 02Z.  THEN
THERE IS A CHANCE FOR MVFR CIGS ASSOCIATED WITH THUNDERSTORMS AT HYS
AND GCK, GENERALLY IN THE BKN050CB RANGE.  THERE IS JUST A SLIGHT
CHANCE FOR STORMS TO MAKE IT TO DDC, AFTER 03Z AND IN THE SAME
BKN050CB CIG CATEGORY.  THESE STORMS WILL BE HIGH BASED IF THEY
OCCUR, AND WILL COULD PRODUCE SOME ISOLATED STRONG CONVECTIVE
WINDS.  AFTER 06Z, THE CHANCE FOR CONVECTION GREATLY DIMINISHES.
