1222 AM CDT MON JUL 16 2012

.AVIATION...

06Z TAFS FOR KLBF AND KVTN. VFR CONDITIONS TO PERSIST. ISOLATED
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP BETWEEN 23Z-06Z
ALONG AND WEST OF HIGHWAY 61 ON MONDAY. OTHERWISE SCATTERED MID

.PREV DISCUSSION... /ISSUED 324 PM CDT SUN JUL 15 2012/

SYNOPSIS...

UPPER LEVEL HIGH PRESSURE HAS SHIFTED EAST INTO WESTERN KANSAS THIS
MORNING...A RESULT OF A DEEPENING TROUGH ACROSS THE NWRN CONUS.
FURTHER EAST...HIGH PRESSURE WAS POSITIONED ACROSS THE WRN ATLANTIC
WITH A CLOSED LOW OVER HUDSON BAY AND AN ASSOC TROUGH EXTENDING
SOUTH INTO THE NRN GREAT LAKES. AT THE SURFACE...A TROUGH OF LOW
PRESSURE EXTENDED FROM ERN MT...SWD INTO ERN WYOMING AND ERN
COLORADO. SRLY WINDS HAVE INCREASED THIS AFTERNOON ACROSS WESTERN
AND NORTH CENTRAL NEBRASKA...AND HAVE GUSTED AS HIGH AS 35 MPH AT
THEDFORD AND VALENTINE. TEMPERATURES AS OF 3 PM CDT RANGED FROM...98
AT BROKEN BOW TO 103 AT VALENTINE.

DISCUSSION...

NEAR TERM...TONIGHT THROUGH WEDNESDAY...MAIN FORECASTING CHALLENGES
ARE TEMPERATURES IN THE NEAR TERM AND LOW PRECIPITATION CHANCES
ACROSS THE NORTHWEST AND NORTH FOR MONDAY THROUGH WEDNESDAY. OVER
THE NEXT 24 HOURS...A DISTURBANCE WILL TRACK ACROSS SRN CANADA AND
WILL A) BEGIN TO SUPPRESS THE RIDGE ACROSS THE CENTRAL CONUS...AND B)
FORCE A WEAK COLD FRONT INTO THE DAKOTAS. ALONG AND AHEAD OF THE
FRONT...A GOOD SETUP IS IN PLACE TO REALLY TORCH OUT OVER NRN
NEBRASKA FOR MONDAY WITH A WEAK FRONTAL BOUNDARY PLOWING INTO AN
INTENSE THERMAL RIDGE. FCST SOUNDINGS...AS WELL AS H85 TEMPS ARE
INDICATIVE OF TEMPS AROUND 105 DEGREES OVER NORTHERN NEBRASKA MONDAY
AFTERNOON. FURTHER SOUTH...AND WELL AHEAD OF THE FRONT TEMPS AROUND
100 LOOK ON TRACK AS COMPRESSIONAL WARMING WILL BE FOCUSED ACROSS
NRN NEBRASKA. HAVE INCREASED THE HIGH TO 106 FOR KVTN AS H85 TEMPS
HAVE TRENDED SLIGHTLY WARMER WITH THIS MORNINGS FCST RUNS. FYI...THE
RECORD FOR VALENTINE MONDAY IS 113 DEGREES SET IN 2006.

MONDAY NIGHT THROUGH WEDNESDAY...

ON MONDAY NIGHT...THE WEAK FRONTAL BOUNDARY WILL EITHER TRACK INTO
NORTHERN NEBRASKA OR SRN SD BASED ON MODEL CHOICE. ATTM...THE NAM IS
MORE AGGRESSIVE WITH PUSHING THE FRONT INTO NRN NEBRASKA WITH THE
GFS KEEPING THIS FEATURE NORTH OF THE AREA. COMPROMISING BETWEEN THE
TWO PLACES THE FRONT ALONG THE SD/NEBR BORDER MONDAY NIGHT INTO
TUESDAY. WITH THIS IN MIND...UTILIZED THE NAM SOLUTION WINDS IN THE
MONDAY NIGHT THROUGH TUESDAY NIGHT TIME FRAME AS THEY SEEMED TO HAVE A
BETTER HANDLE ON THE BOUNDARY LAYER...THEN DIRECTIONALLY ADJUSTED
THEM TO THE SOUTHEAST AND SOUTH SOME TO ACCOMMODATE A "MODEL
COMPROMISED" NORTHERN FRONTAL BOUNDARY. WITH THIS IN MIND...POPS
DURING THE MONDAY NIGHT THROUGH TUESDAY NIGHT PERIOD WILL BE
CONFINED TO THE VICINITY OF THE FRONT OVER NRN AND NWRN NEBRASKA.
FURTHER SOUTH...CAPPING SHOULD REMAIN IN PLACE...HINDERING ANY TSRA
DEVELOPMENT. ON TUESDAY...WITH THE FRONT STALLED ACROSS NRN
NEBRASKA...HIGHS WILL RANGE FROM AROUND 90 IN THE
NORTHWEST...TO NEAR 100 IN PORTIONS OF SOUTHWESTERN AND CENTRAL
NEBRASKA. FOR WEDNESDAY...LEFT POPS IN THE FCST IN THE WEST AND
NORTH AS THE MODELS CONTINUE TO INDICATE WEAK SHORTWAVE FORCING
LIFTING INTO THE FORECAST AREA FROM COLORADO AND ERN WYOMING. A
SURFACE CONVERGENCE ZONE IS EXPECTED TO LINGER ACROSS THE PANHANDLE
AND NORTHWESTERN NEBRASKA WHICH WILL AIDE IN TSRA DEVELOPMENT
WEDNESDAY INTO WEDNESDAY NIGHT.

LONG TERM...THURSDAY THROUGH SUNDAY. VERY HOT AND MAINLY DRY
CONDITIONS ARE EXPECTED THIS PERIOD...AS THE UPPER LEVEL RIDGE OF
HIGH PRESSURE BECOMES ESTABLISHED DIRECTLY OVERHEAD ONCE AGAIN. THIS
SYNOPTIC SET UP LOOKS SIMILAR TO LATE JUNE...WHEN WE HAD SEVERAL 100
DEGREE DAYS IN A ROW. WENT AHEAD AND NUDGE HIGH TEMPS UP TO AROUND
100 DEGREES. POSSIBLE A LITTLE COOLER /HIGHS BACK INTO THE 90S/ FOR
SUNDAY AS A COLD FRONT SLOWLY SAGS SOUTH INTO THE AREA. WARM
OVERNIGHTS AS WELL...WITH LOWER 70S FOR LOWS IN MANY SPOTS. HIGHER
ELEVATIONS OF THE PANHANDLE WILL BE THE EXCEPTION...WITH LOWS IN THE
MID 60S.

AVIATION...

OTHER THAN SOME SCT CIRRUS CLOUDS...CLR SKIES AND VFR CONDITIONS
WILL PREVAIL THE NEXT 24 HRS. WINDS WILL BE SOUTH TO SOUTHEAST AT 10
TO 20 KTS...WITH GUSTS NEARING 30 KTS ACROSS PORTIONS OF NORTH
CENTRAL NEB THIS AFTERNOON...INCLUDING THE KVTN TAF SITE.
