Area forecast discussion, Jun 14, 2:01 PM MDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
301 PM CDT SUN JUN 14 2015

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 300 PM CDT SUN JUN 14 2015

BUSY AFTERNOON ACROSS THE AREA. NUMEROUS LOW LEVEL BOUNDARIES WITH
CONVECTION DEVELOPING IN SUB TROPICAL TYPE AIR MASS. OVERALL LARGE
SCALE SHEAR IS QUITE WEAK...BUT LOCALLY BACKED WIND NEAR THE
BOUNDARIES IS CREATING ENOUGH TURNING THAT SOME WEAK LANDSPOUT
TORNADOES HAVE OCCURRED AND WILL CONTINUE TO BE POSSIBLE INTO THIS
EVENING. HAIL THREAT IS RATHER LOW DUE TO WEAK SHEAR AND SUB
TROPICAL TYPE OF ATMOSPHERE...BUT STRONG WINDS ARE POSSIBLE AS
STORMS COLLAPSE AND DCAPE VALUES QUITE HIGH. WATER VAPOR SHOWS
APPROACHING VORT MAX MOVING NORTH FROM SOUTHWEST KS...LIKELY HELPING
WITH THE LARGE SCALE LIFT AND DEVELOPING STORMS ACROSS THE REGION.
AS THIS FEATURE LIFT NORTH TONIGHT...EXPECT A CONTINUED CHANCE FOR
SHOWERS/STORMS. HAVE ADDED LOCALLY HEAVY RAIN ACROSS SOUTHWEST INTO
CENTRAL NEBRASKA DUE TO HIGH PWATS...NEARING 1.50 INCHES AT KLBF
THIS EVENING.

COLD FRONT WILL DROP SOUTH THOUGH THE AREA LATE TONIGHT...WITH
COOLER CONDITIONS AND NORTHEAST WINDS EXPECTED MONDAY. WILL CONTINUE
SOME MENTION FOR SHOWERS ANS STORMS...AS MID LEVEL
FRONTOGENESIS/LIFT PERSISTS.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 300 PM CDT SUN JUN 14 2015

MONDAY NIGHT THROUGH WEDNESDAY...TWO NORTHERN STREAM
DISTURBANCES/MESOSCALE CONVECTIVE SYSTEMS OR MCSS WILL MOVE THROUGH
SD AND NEB. THE FIRST MOVING THROUGH SD LATE MONDAY NIGHT AND EARLY
TUESDAY PRESUMABLY WILL SEND AN OUTFLOW BOUNDARY INTO NEB PROVIDING
FOCUS FOR A SECOND MCS TO FORM LATE TUESDAY AFTN THROUGH TUESDAY
NIGHT. NOTE THE NAM WAS GENERALLY PREFERRED FOR THIS EVOLUTION AS
THE GFS WAS DEEPLY MIXED AND CAPPED PREVENTING STORM DEVELOPMENT AT
TIMES.

SPC SUGGESTED SEVERE WEATHER WOULD BE POSSIBLE LATE TUESDAY AND CAPE
AND BULK SHEAR CALCULATIONS CERTAINLY SUPPORT THIS. K INDICES ARE
WELL INTO THE 40S AND PWAT IS IN THE 1.4 INCH RANGE. STORM MOTION IN
THE NAM SOUNDING AT VALENTINE AREA EAST AT 20 TO 25 MPH. A SOLID
COLD FRONT MOVES THROUGH THE FCST AREA IN THE WAKE OF THE MCS. DRY
WEATHER IS EXPECTED WEDNESDAY.

THE SITUATION MONDAY NIGHT IS UPSLOPE MOISTURE RETURN AND A
DISTURBANCE MOVING THROUGH WYOMING. THIS SYSTEM WOULD LIKELY JUST
AFFECT NORTHWEST NEB AND SD. THE SYSTEM TUESDAY AFTN AND NIGHT IS
EXPECTED TO BE MORE WIDESPREAD WITH POPS IN THE 30 TO 50 PERCENT
RANGE.

WEDNESDAY NIGHT THROUGH SUNDAY...THE BEST RAIN CHANCES DEVELOP
WEDNESDAY NIGHT ACROSS SWRN NEB AND THURSDAY/FRIDAY NIGHTS ACROSS
NRN NEB. THESE DISTURBANCES WILL LIKELY FORM MCSS AS PWAT INCREASES
TO OVER 1.25 INCHES IN THE GFS.

A STRONG CAP WILL DEVELOP THURSDAY AND FRIDAY FAVORING STORM
DEVELOPMENT MOSTLY NORTH OF THE FCST AREA. STORMS WEDNESDAY FORM OFF
THE COLORADO FRONT RANGE IN A MORE WEAKLY CAPPED ENVIRONMENT AND
MOVE EAST ARRIVING IN THE SOUTHWEST IN THE EVENING OR LATER. ONLY
THE GFS SHOWS THIS SYSTEM DEVELOPING ACROSS SWRN NEB WEDNESDAY BUT
THE ECM AND GFS ARE ONBOARD WITH THE MCSS FORMING THURSDAY AND
FRIDAY NIGHTS ACROSS SD WHICH BRUSH NRN NEB.

AS ALWAYS...MCSS PRODUCE OUTFLOW WHICH COULD SEND COOL AIR AND FOCUS
FOR SUBSEQUENT STORM DEVELOPMENT INTO THE FCST AREA. THIS WOULD
UPSET THE TEMPERATURE FORECAST AND INCREASE RAIN CHANCES IN SOME
AREAS.

FRIDAY WOULD BE THE WARMEST DAY WITH HIGHS IN THE LOWER 90S ALONG
AND SOUTH OF INTERSTATE 80. THE DGEX SHOWED UPPER 90S AND GIVEN THAT
THE ECM AND GFS SHOW H700MB RISING TO OVER 15C FRIDAY...THIS MODEL
MIGHT NOT BE TOO FAR OFF. BOTH 00Z AND 12Z ECM RUNS SHOW DEWPOINTS
FRIDAY IN THE UPPER 60S TO NEAR 70 ALONG AND EAST OF HIGHWAY 83
WHICH WOULD LIKELY HOLD HIGHS DOWN. THE GFS WAS DRIER AND MORE
DEEPLY MIXED LIKE THE DGEX. EITHER WAY FRIDAY WILL BE HOT AND THE
MODELS WERE HINTING AT THIS YESTERDAY.

COOLER AIR MOVES IN SATURDAY AND SUNDAY. THE UPPER LEVEL DISTURBANCE
IS ROBUST AND WILL PULL DOWN RAIN COOLED HIGH PRESSURE. HIGHS NEXT
WEEKEND WOULD LIKELY BE IN THE 70S TO LOWER 80S.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 144 PM CDT SUN JUN 14 2015

SCATTERED THUNDERSTORMS ARE POSSIBLE ACROSS MOST OF THE AREA INTO
THIS EVENING. LOCALLY GUSTY WINDS AND BRIEF MVFR/IFR MAY BE
EXPERIENCED IN AND NEAR ANY THUNDERSTORM...OTHERWISE VFR IS
EXPECTED.
