AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
136 PM MDT SUN JUN 7 2015

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 135 PM MDT SUN JUN 7 2015

LATEST UPPER AIR ANALYSIS INDICATES A LONG WAVE TROUGH OVER THE
ROCKIES EXTENDING INTO THE NORTHERN PLAINS.  SMALLER SCALE SHORT
WAVE TROUGHS CONTINUE TO EJECT DOWNSTREAM AHEAD OF THE MAIN FEATURE.
AT THE SURFACE A COOL FRONT HAD MOVED THROUGH THE AREA THIS MORNING
BRINGING A BRIEF PERIOD OF OVERCAST SKY.  A BIT FURTHER NORTH A
SECONDARY COLD FRONT WAS LOCATED OVER FAR NORTHEAST COLORADO
EXTENDING INTO CENTRAL NEBRASKA.  SOUTH OF THE TRI-STATE AREA A
SURFACE TROUGH WAS LOCATED ACROSS SOUTHWEST KANSAS EXTENDING INTO
NORTHEAST ARIZONA.

FOR THE REST OF THE AFTERNOON THE COOL FRONT WILL BE QUASI-
STATIONARY OVER THE SOUTHWEST HALF OF THE AREA WHILE THE SECONDARY
COLD FRONT FURTHER NORTH BEGINS TO MOVE SOUTH AHEAD OF THE LONG WAVE
TROUGH.  AHEAD OF THE COOL FRONT THE ENVIRONMENT IS FAIRLY DRY...AS
INDICATED BY CONDENSATION PRESSURE DEFICITS OVER 100MB BELOW 500MB.
HIGHER UP IN THE ATMOSPHERE CONDENSATION PRESSURE DEFICITS DECLINE
AHEAD OF A SHORT WAVE TROUGH MOVING IN FROM SOUTHEAST COLORADO.
DUE TO SOME HIGHER LEVEL MOISTURE AVAILABLE AND THE APPROACHING
TROUGH...WILL HAVE SOME LOW CHANCES FOR RAINFALL AHEAD OF THE COOL
FRONT. AM EXPECTING THE MAJORITY OF THE STORM ACTIVITY WITH THIS
TROUGH TO BE SOUTH OF THE AREA ALONG THE SURFACE TROUGH. BETWEEN
THE COOL FRONT AND THE SECONDARY COLD FRONT CONDENSATION PRESSURE
DEFICITS ARE MORE FAVORABLE FOR CONVECTION. AS THE AFTERNOON
PROGRESSES AND THE LONG WAVE TROUGH AXIS APPROACHES...LIFT ALONG
THE COOL FRONT WILL INCREASE ALLOWING SCATTERED STORMS TO DEVELOP.
IN ADDITION EXPECT SCATTERED STORMS TO DEVELOP OVER THE HIGHER
TERRAIN AND MOVE EAST INTO THE AREA DURING THE LATE AFTERNOON.

WITH THE HIGHEST DEW POINTS BETWEEN THESE TWO BOUNDARIES AND 0-6KM
BULK SHEAR OF 50KTS...EXPECT STRONG TO SEVERE STORMS TO DEVELOP.
DURING THE LATE AFTERNOON THROUGH EARLY EVENING.  THE BEST MIXED
LAYER INSTABILITY WILL BE OVER THE EAST HALF OF THE AREA BUT THE
STRONGEST UPPER LEVEL LIFT WILL BE OVER THE WEST HALF.  SOUNDINGS
OVER THE CENTRAL PART OF THE AREA WOULD SUPPORT HAIL UP TO 2 INCHES
IN DIAMETER.  WITH CLOUD BASES CLOSE TO 10K FT ABOVE GROUND AND DRY
ADIABATIC LAPSE RATES BELOW CLOUD LEVEL...SEVERE WINDS ARE POSSIBLE
WITH ANY STORMS THAT DEVELOP...BUT ESPECIALLY FOR ANY STORMS THAT
MOVE EAST OUT OF COLORADO.  0-1KM BULK SHEAR IS 5KTS SO DO NOT
ANTICIPATE THERE TO BE MUCH OF A TORNADO THREAT.  HOWEVER IF ANY
STORMS LINGER ALONG COOL FRONT THEY WILL BE MORE FAVORABLE TO
GENERATE A TORNADO.  WITH PRECIPITABLE WATER VALUES STILL REMAINING
VERY HIGH..IN THE TOP 75-90 PERCENTILE OR MORE AND STORM MOTION
AROUND 20 MPH...HEAVY RAINFALL WILL BE LIKELY WITH ANY STORMS THAT
DEVELOP.  IF STORMS TRAIN ALONG THE EITHER FRONT THERE COULD BE A
RISK OF FLASH FLOODING.

EARLY THIS EVENING EXPECT THE STORM COVERAGE TO PEAK...WITH THE
BEST STORM COVERAGE WEST OF HIGHWAY 25.  AS THE EVENING PROGRESSES
THE INSTABILITY WILL DECLINE FROM NORTH TO SOUTH AS THE UPPER
LEVEL LONG WAVE TROUGH AXIS MOVES SOUTH THROUGH THE AREA...WITH
STORM ACTIVITY FOLLOWING A SIMILAR TREND.  THERE WILL BE SOME
LINGERING LIFT BEHIND THE TROUGH AXIS AFTER MIDNIGHT...SO THERE MAY
BE SOME ISOLATED STORMS OVERNIGHT.

MONDAY AN 850MB RIDGE AND SURFACE HIGH PRESSURE MOVE THROUGH THE
AREA.  DURING THE MID TO LATE AFTERNOON ISOLATED STORM MAY DEVELOP
OVER THE FAR SOUTHWEST PART OF THE AREA BEHIND THE 850MB RIDGE AND
THE SURFACE HIGH.

LOWS TO NIGHT WILL BE AT OR A FEW DEGREES BELOW LOWS FROM LAST
NIGHT.  HIGHS TOMORROW WILL BE WARMER THAN TODAY DUE TO WAA FROM ON
THE BACKSIDE OF THE SURFACE HIGH.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 1251 PM MDT SUN JUN 7 2015

UPPER RIDGING WILL RESULT IN WARM AND DRY CONDITIONS THROUGH
TUESDAY. THE RIDGE BREAKS DOWN ON WEDNESDAY WITH SHORTWAVE TROUGH
COMING OUT OF THE CENTRAL ROCKIES. MODELS ARE MORE AGGRESSIVE WITH
THIS SYSTEM SO INTRODUCED SLIGHT TO CHANCE POPS FOR WEDNESDAY
AFTERNOON. MODERATE INSTABILITY IS FORECAST BUT DEEP LAYER SHEAR
WILL BE LESS THAN 20KTS...SO EXPECTING MAINLY PULSE TYPE STORMS
WITH A LOW THREAT OF HAIL OR GUSTY WINDS.

COLD FRONT ASSOCIATED WITH A NORTHERN STREAM UPPER TROUGH WILL
SLIDE THROUGH THURSDAY MORNING. IT SHOULD SETTLE ALONG THE
SOUTHEASTERN FRINGES OF THE FORECAST AREA THURSDAY AFTERNOON AND
MAY BE THE FOCUS FOR CONVECTIVE INITIATION. OTHER STORMS WILL
DEVELOP IN THE POST FRONTAL ENVIRONMENT NEAR THE FRONT RANGE AND
CHEYENNE RIDGE MOVING INTO THE AREA THURSDAY NIGHT. DEEP LAYER
SHEAR WILL BE QUITE STRONG AT NEAR 50KTS...BUT INSTABILITY WILL
BE RATHER LIMITED NORTH OF THE FRONT.

THE END OF THE LONG TERM PERIOD WILL BE CHARACTERIZED BY A RATHER
WEAK FLOW ALOFT. THERE WILL BE GRADUAL MOISTENING OF THE LOW
LEVELS WITH INCREASING INSTABILITY. THERE WILL BE CHANCES OF
MAINLY AFTERNOON AND EVENING THUNDERSTORMS JUST ABOUT EVERY
DAY...BUT WITH LACK OF ANY STRONG SYNOPTIC SCALE FORCING COVERAGE
WILL BE WIDELY SCATTERED AT BEST. ANEMIC DEEP LAYER SHEAR WILL
ALSO LIMIT THE SEVERE THREAT.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1121 AM MDT SUN JUN 7 2015

VFR CONDITIONS FORECAST FOR THE 18Z TAFS. EXPECT STORM COVERAGE TO
BE PRIMARILY WEST OF KMCK LATE THIS AFTERNOON THROUGH THE EVENING.
BEST CHANCES FOR STORMS TO BE NEAR KGLD WILL BE EARLY EVENING. IF
STORMS MOVER OVER KGLD...HEAVY RAINFALL MAY REDUCE VISIBILITIES
AND STRONG VARIABLE WINDS ARE LIKELY.
