AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
322 PM CDT THU AUG 24 2006

.SYNOPSIS...
PREFRONTAL TROUGH MOVING EAST ACROSS CENTRAL NEBRASKA AND
EXTENDING WEST TO ALONG THE COLORADO WYOMING BORDER. ATTM
CONVECTION DEVELOPING ALONG THE BOUNDARY SW OF KIBM WITH ISOLATED
HIGH BASED RETURNS FURTHER EAST.
&&

.DISCUSSION...
IN THE NEAR TERM FORECAST TRENDED TOWARD THE WRF SOLUTION WITH
MODEL BASED POPS USED AS DRY AIR SHOWN IN SOUNDING PROFILE AND
WARM MID LEVEL TEMPERATURES WILL INHIBIT OVERALL CONVECTION
POTENTIAL. THIS EVENING ISOLATED THUNDERSTORMS ARE POSSIBLE WITH
DAMAGING WINDS THE MAIN THREAT AS STRONG WAVE MOVES SOUTHEAST
WITH HIGHER IMPACTS TO AREAS TO OUR NORTH AND SOUTHWEST. OVERNIGHT
THE COLD FRONT MERGES WITH THE PREFRONTAL TROUGH AND MOVES SOUTH.
FRIDAY SHORTWAVE RIDGING WILL KEEP PRECIP CLOSE TO NIL UNTIL AFTERNOON
AS THE RIDGE AXIS MOVES EAST. THEN AS LAPSE RATES STEEPEN AND
ADDITIONAL LIFT IS CREATED AS A SERIES OF WAVES MOVE EAST THAT THE
AIR COLUMN WILL HAVE A CHANCE TO MOISTEN AS UPSLOPE WINDS HELP
MOISTEN THE LOWER LAYERS FOR RAIN TO POSSIBLY REACH THE GROUND IN
THE PANHANDLE AND FAR WEST. HOWEVER THUNDERSTORMS THAT DO FORM
WILL STILL BE HIGH BASED WITH DRY LIGHTNING STILL A THREAT FOR THE
FIRE DANGER THROUGH THE AFTERNOON. THEN TEMPERATURES WILL BE
IMPACTED BY THE ADDITIONAL CLOUD COVERAGE THAT WILL LIKELY LINGER
AS THE H5 TROUGH AXIS IN THE NORTHWEST CLOSES OFF AND MOVES
SOUTHEAST THROUGH SUNDAY. LONG RANGE MODELS DID SHOW ENOUGH
VARIABILITY TO LIMIT LARGE CHANGES INTO THE EXTENDED ATTM WITH
MAINLY DRY CONDITIONS CONTINUING.
