AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
348 PM CDT THU JUN 14 2012

FORECAST CHALLENGE TONIGHT IS POPS AS COOL FRONT MOVES SOUTH AND
STALLS IN THE FAR SOUTHWEST TO THE KANSAS STATE LINE.

AT 19Z NARROW LINE OF RETURNS ON THE RADAR OVER THE SOUTHWEST NEAR
HAYES CENTER AND EXTENDS NORTHEAST THROUGH CENTRAL HOLT COUNTY. THE COOL
FRONT HAS PUSHED EAST INTO EASTERN NEBRASKA AND EXTENDS SOUTHWEST
INTO FAR SOUTHWEST NEB ATTM. THIS FORECAST CYCLE THERE REMAINS A
MODEL SPREAD WHERE A MODEL BLEND WAS USED THROUGH SATURDAY. A
DRIER APPROACH WAS TAKEN BUT NOT AS DRY AS THE NAM SUGGESTS WHERE
THE FRONT THAT PUSHES SOUTH TONIGHT WILL WASHOUT WHILE RETURNING
NORTH FRIDAY.

TONIGHT ISOLATED TO SCATTERED THUNDERSTORMS MAY DEVELOP ALONG AND
SOUTH OF THE BOUNDARY AFTER 4 PM IN THE FAR SOUTHWEST. DISTURBANCES
SEEN ON WATER VAPOR WILL LIFT NORTHEAST INTO THE EVENING WHERE THE
THREAT FOR SEVERE THUNDERSTORM DEVELOPMENT EXISTS FOR FRONTIER
COUNTY INTO THE EVENING. THE EVENTUAL FRONTAL POSITION WILL IMPACT
THE GOING FORECAST AS MODELS SUGGEST A COMPLEX FORMING AND
DRIVING THE FRONT EAST AND SOUTH OVERNIGHT...WITH THE MAIN
QUESTION TO BE HOW FAR SOUTH. OVERNIGHT SOUTHERLY RETURN FLOW
DEVELOPS ON THE HIGH PLAINS WHERE MOISTURE DEEPENS AND THE UPSLOPE
MAY ALSO HELP DEVELOP EXTENSIVE LOWS CLOUDS IN THE WEST...SO FOR
NOW HAVE INCREASED SKY COVER ACROSS THE WEST AFTER MIDNIGHT.

FRIDAY FOCUS SHIFTS TO THE NORTHWEST AS THE NEXT STRONG DISTURBANCE
MOVES OUT ON THE PLAINS. WEAK HIGH PRESSURE BUILDS EAST DURING
THE DAY FOR A MAINLY DRY FORECAST THEN THUNDERSTORMS REDEVELOPING
IN THE NORTHWEST BY EVENING. THE 18Z NAM MODEL RUN COMING IN ATTM
WHERE POPS MAY NEED TO BE RAISED OVERNIGHT FRIDAY INTO SATURDAY
MORNING AS SHORTWAVE TROUGH IS PROJECTED TO MOVE FURTHER SOUTHEAST
THAN EARLIER SHOWN. THROUGH THE FORECAST PERIOD TEMPERATURE
GUIDANCE CLOSE AND FOLLOWED.

BEST CASE SCENARIO FOR SATURDAY WILL BE SHOWERS EXITING IN THE
MORNING THEN GOOD SUBSIDENCE FOR CLEARING INTO THE AFTERNOON...
ALONG WITH WARMING TEMPERATURES. SUNDAY THROUGH TUESDAY ZONAL FLOW
CONTINUES ACROSS THE NORTHWEST THAT WILL CARRY A SERIES OF
DISTURBANCES EAST. MODELS ARE ADJUSTING TO TIMING DIFFERENCES THAT
REFLECTS DRIER CONDITIONS THROUGH MONDAY AS H7 TEMPERATURES WARM
AND THE THERMAL RIDGE EXTENDS NORTH AND EAST WHILE A COLD FRONT
MOVES SOUTH. MONDAY NIGHT THE FRONT STALLS THROUGH CENTRAL NEB TO
BE SERVE AS A FOCUS FOR STORM DEVELOPMENT THROUGH WEDNESDAY
MORNING.

&&

.AVIATION...(ISSUED 1120 PM CDT)

VFR CONDITIONS ARE ANTICIPATED AT BOTH KLBF AND KVTN THROUGH 18Z
FRIDAY. CURRENT CLOUD COVER AT KLBF WILL CONTINUE TO ERODE AND LIFT
THROUGH THE AFTERNOON. SCATTERED THUNDERSTORMS WILL BE POSSIBLE
GENERALLY SOUTH AND EAST OF A LINE FROM NORTH PLATTE TO BROKEN
BOW...SO HAVE LEFT OUT ANY MENTION OF TSRA IN THIS KLBF TAF
UPDATE. COLD FRONT HAS CLEARED KLBF WITH WINDS NOW OUT OF THE
NORTH. WINDS WILL CONTINUE TO BE GUSTY AT BOTH TAF SITES THROUGH
THE DAY BEFORE CALMING AND SWITCHING TO OUT OF THE EAST OVERNIGHT.
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE IN WESTERN NEBRASKA
TOMORROW...HOWEVER NOT EXPECTING ANYTHING TO OCCUR WITHIN THIS TAF
PERIOD.
