.MESOSCALE DISCUSSION...
ISSUED AT 723 PM MDT WED JUL 9 2014

UNSTABLE AND SHEARED ENVIRONMENT REMAINS IN PLACE AT THIS TIME.
HRRR CONTINUES TO SHOW A LINE FILLING IN ACROSS THE REGION BUT
BEGINNING TO THINK CAP MAY BE TOO STRONG TO OVERCOME OVER THE
CENTRAL CWA. COMPLEX MOVING IN FROM NORTHEAST COLORADO WILL
CONTINUE ITS MOVEMENT SOUTH-SOUTHEAST ACROSS EAST COLORADO AND
LIKELY MAKING IT INTO WEST CENTRAL KANSAS OVER THE NEXT FEW HOURS.
MAIN THREATS WITH THESE STORMS IS HAIL TO THE SIZE OF
QUARTERS...DAMAGING WINDS AND NEAR ZERO VISIBILITY DUE TO BLOWING
DUST WITH THE WINDS.

FARTHER NORTHEAST...STORM MOVING INTO FRONTIER AND HAYS COUNTY
NEBRASKA HAS BEEN PRODUCING GOLF BALL TO BASEBALL SIZE HAIL FOR THE
BETTER PART OF THE PAST 2 HOURS. THIS STORM IS MOVING INTO AN
ENVIRONMENT WITH 2000-2500 J/KG CAPE AND 0-6 KM BULK SHEAR OF 50+
KTS. THIS STORM IS HEADING DIRECTLY TOWARDS MCCOOK NEBRASKA AND
EVENTUALLY INTO NORTHWEST KANSAS. THIS STORM SHOULD MAINTAIN ITS
SUPERCELL CHARACTERISTICS FOR ANOTHER FEW HOURS BEFORE GROWING
UPSCALE INTO ANOTHER MCS. MAIN SHORT-TERM THREAT IS DAMAGING WINDS
AND HAIL TO THE SIZE OF BASEBALLS. SIGNIFICANT HAIL THREAT SHOULD
GRADUALLY DIMINISH LATE TONIGHT...AFTER 10 PM MDT.

FOR BOTH COMPLEXES OF STORMS...DEVELOPING LOW LEVEL JET SHOULD
CONTINUE TO FEED THESE STORMS UNSTABLE AIR FROM THE SOUTH. SEVERE
THREAT WILL LIKELY PERSIST THROUGH MIDNIGHT MDT.

&&

.UPDATE...
ISSUED AT 453 PM MDT WED JUL 9 2014

ISSUED SEVERE THUNDERSTORM WATCH 408 UNTIL MIDNIGHT MDT. WILL BE
UPDATING THE GRIDS TO REFLECT LATEST THINKING FOR THUNDERSTORMS
THIS EVENING. UPDATE SHOULD BE OUT WITHIN NEXT 30-45 MINUTES.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 1229 PM MDT WED JUL 9 2014

A CHANCE FOR STRONG TO SEVERE STORMS TODAY...OTHERWISE A HOT AND
BREEZY DAY. UPPER LEVEL FLOW REMAINS NORTHWESTERLY AS A RIDGE OVER
THE GREAT BASIN SLOWLY PROGRESSES EASTWARD INTO THE HIGH PLAINS
TONIGHT. AT LOW LEVELS SOUTHERLY WINDS WILL BRING IN WARM AIR...WITH
A RETURN TO THE 90S ACROSS THE REGION.

TODAY...SUNNY AND BREEZY MOST OF THE DAY. SOUTHERLY WINDS WERE
ALREADY GUSTING TO 30 MPH THIS MORNING AND EXPECT THE GUSTY WINDS TO
CONTINUE THROUGHOUT THE AFTERNOON. WARMER TODAY...850MB TEMPS
GENERALLY IN THE LOW TO MID 20S C TODAY...SUPPORTIVE OF HIGHS IN THE
LOW TO MID 90S. SOME GUIDANCE ACTUALLY KEEPS HIGHS IN THE UPPER
80S...BUT THINK MOST PLACES WILL MANAGE TO HIT AT LEAST 90 TODAY.
SKIES WILL REMAIN SUNNY FOR MOST OF THE DAY...HAVE SOME INCREASED
CLOUD COVER ACROSS NORTHEAST COLORADO AND SOUTHWEST NEBRASKA
ASSOCIATED WITH SOME SHOWERS AND STORMS THAT MOVED SOUTH THROUGH FAR
WESTERN NEBRASKA EARLIER THIS MORNING AND HAVE SINCE GENERALLY
DISSIPATED.

STILL HAVE SOME UNCERTAINTY ABOUT INITIATION OF STORMS TODAY.
SURFACE TROUGH DEVELOPMENT IN EASTERN COLORADO APPEARS ON TRACK TO
POSSIBLY SERVE AS A FOCUS FOR DEVELOPMENT IN EASTERN COLORADO AND
WESTERN KANSAS...ESPECIALLY AS IT TRACKS EASTWARD. MORNING GUIDANCE
STILL PERSISTENT WITH A STUBBORN CAP AROUND 700MB PRODUCING 100-150
J/KG CIN THIS AFTERNOON...WHICH COULD PREVENT DEVELOPMENT WITHOUT
SUFFICIENT FORCING. STILL...BESIDES THE CAP SOUNDINGS ARE FAVORABLE
FOR STRONG TO SEVERE THUNDERSTORMS. MLCAPE VALUES WILL BE AROUND
1500 J/KG LATE THIS AFTERNOON. LOW AND MID-LEVEL LAPSE RATES ARE
EXPECTED TO BE STEEP. WIND PROFILES ARE SUPPORTIVE OF ORGANIZED
THUNDERSTORM DEVELOPMENT WITH 30 TO 40 KTS OF EFFECTIVE SHEAR
AVAILABLE LATE THIS AFTERNOON. STORM MOTIONS OF LESS THAN 10 KTS
COULD ALSO LEAD TO THE POSSIBILITY OF FLASH FLOODING.

TONIGHT...EXPECT SCATTERED STRONG TO SEVERE THUNDERSTORMS IN
SOUTHWEST NEBRASKA AND NORTHWEST KANSAS TONIGHT...WITH THE BEST
CHANCE EAST OF HIGHWAY 83. AS LOW LEVEL JET DEVELOPS OVERNIGHT THIS
COULD SUSTAIN DEVELOPMENT AS STORMS MOVE EASTWARD. EXPECT STORMS TO
DIMINISH AFTER MIDNIGHT FOR MOST LOCATIONS. AS STORMS CLEAR OUR
SKIES WILL BECOME MOSTLY CLEAR AND WINDS REMAIN LIGHT AND GENERALLY
OUT OF THE SOUTH.

TOMORROW...WARMER AND BREEZY. MID-LEVEL RIDGE MOVES ACROSS THE
CENTRAL HIGH PLAINS WITH ANOTHER LOW/SFC TROUGH DEVELOPING IN
NORTHEAST COLORADO. A NUMBER OF WEAK MID-LEVEL SHORTWAVE TROUGHS
WILL MOVE ACROSS THIS RIDGE...WHICH WILL CREATE A FAVORABLE
ENVIRONMENT FOR TERRAIN-BASED STORMS OFF THE CHEYENNE RIDGE AND
PALMER DIVIDE. AT THIS POINT IT APPEARS THE BEST CHANCE FOR STORMS
WILL REMAIN NORTH OF THE CWA...BUT CANNOT RULE OUT A FEW ISOLATED
STORMS LATE IN THE DAY. CONDITIONS WILL NOT BE FAVORABLE FOR
ORGANIZED SEVERE THUNDERSTORMS...WITH LITTLE CAPE /LESS THAN 500
J/KG SBCAPE/ AND AROUND 20 KTS EFFECTIVE SHEAR. 850MB TEMPS REACHING
THE LOW 30S C...WHICH UNDER MOSTLY SUNNY SKIES WILL LEAD TO HIGHS IN
THE MID 90S...PERHAPS NEAR 100 SOUTH OF HIGHWAY 40.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1249 PM MDT WED JUL 9 2014

UPPER RIDGE CENTERED OVER THE SOUTHERN PLAINS WILL BE THE MAIN
FEATURE THROUGH SATURDAY. WEAK DISTURBANCES COMING OUT OF NORTHERN
COLORADO OVER THE TOP OF THE RIDGE WILL BRING SLIGHT TO LOW
CHANCES OF MAINLY AFTERNOON/EVENING THUNDERSTORMS...BEST CHANCES
IN EASTERN COLORADO AND SOUTHWEST NEBRASKA. THE RIDGE IS FORECAST
TO GRADUALLY RETROGRADE THE REMAINDER OF THE LONG TERM PERIOD...TO
THE CENTRAL ROCKIES SUNDAY AND MONDAY THEN REACHING THE GREAT
BASIN TUESDAY AND WEDNESDAY. THIS WILL OPEN THE DOOR TO DISTURBANCES
COMING DOWN FROM THE NORTHERN PLAINS IN THE NORTHWEST FLOW ALOFT
SO PRECIPITATION CHANCES WILL CONTINUE. TEMPERATURES WILL START
THE PERIOD ABOVE NORMAL...BUT AS THE RIDGE MOVES WEST COOLER AIR
WILL BE ALLOWED TO COME SOUTH WITH TEMPERATURES GRADUALLY COOLING
TO BELOW NORMAL BY THE END OF THE PERIOD.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 543 PM MDT WED JUL 9 2014

CONFIDENCE HAS INCREASED IN THUNDERSTORMS IMPACTING EITHER
TERMINAL THIS EVENING. BASED ON CURRENT RADAR/SAT TRENDS AND SHORT
TERM GUIDANCE HAVE NARROWED DOWN THE WINDOW OF VCTS FOR MCK AND
GLD AND INCLUDED A TEMPO GROUP FOR THE MOST LIKELY TIME THAT
STORMS WILL IMPACT THE TERMINAL. STRONG WIND GUSTS AND HAIL ARE
POSSIBLE. OTHERWISE SOUTH/SOUTHEAST WINDS MAY GUST FOR ANOTHER
HOUR OR SO BUT AFTER SUNSET THE GUSTS SHOULD SUBSIDE. SPEEDS FROM
12-18 KNOTS SEEM LIKELY THROUGH THE EVENING WITH A SLOW DECREASE
LATER TONIGHT AND A SLIGHT VEERING TO MORE SOUTH/SOUTHWEST BY
MORNING AT GLD. MCK WILL REMAIN SOUTH/SOUTHEAST WITH GUSTS
INCREASING LATE TOMORROW MORNING AND LASTING INTO EARLY TOMORROW
EVENING. VFR CONDITIONS SHOULD PREVAIL EXCEPT FOR THE POSSIBILITY
OF BRIEF REDUCTIONS IN VISIBILITY IF A STORM DIRECTLY IMPACTS
EITHER TERMINAL.
