SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
254 PM CDT MON AUG 21 2000

BOUNDARY PLACEMENT MAIN QUESTION

18Z SFC MAP SHOWED SEMI-STATIONARY FRONT FROM EAST CENTRAL NEBRASKA
TO SOUTHWEST KANSAS.  DRIER...WARM AIRMASS AHEAD OF BOUNDARY HAS
ALLOWED TEMPS TO RISE INTO THE 90S AND THIS DRY AIR HAS DONE WELL AT
ERODING STRATUS ACROSS CWA THIS MORNING.  BEHIND BOUNDARY...LLVL
MOISTURE AROUND WITH DPS IN THE MID 60S.

USED A ETA/AVN BLEND FOR THE FORECAST.  MODELS SITUATE BOUNDARY
ALONG KS/NEB BORDER TONIGHT.  CONVECTION ALREADY ONGOING IN CO TO
SPREAD EAST ACROSS SOUTHERN CWA TONIGHT AS SHORTWAVE MOVES THRU AND
LLVL JET INCREASES.  CORFIDI VECTORS TRACK ORGANIZED CONVECTION TO
THE E/SE.  WILL TEMPER POPS SLIGHTLY N/S WITH SLGHT CHC NORTH TO 40
PCNT IN SOUTHERN COUNTIES...KEEPING HIGHEST POPS ALONG BOUNDARY.
STRATUS AND FOG POSSIBLE AGAIN NORTH OF THE BOUNDARY WITH SOUTHERN AREAS
DEPENDENT UPON EXTENT OF PCPN.  WILL MENTION THE POSSIBILITY OF THIS
IN ZONES.

ON TUESDAY...BOUNDARY LIFTS NORTH AND RESTS ALONG I-80.  SHLD SEE
QUITE THE RANGE IN TEMPS AGAIN WITH MID 80S NORTH OF BOUNDARY TO MID
90S IN THE SOUTH.  A SECOND SHORTWAVE CLIPS SOUTHEAST THROUGH NC/NE
NEBRASKA EARLY IN THE DAY AND WILL INCLUDE POPS IN FORECAST WITH
THIS FEATURE.  THE PATTERN REMAINS UNSETTLED WITH THE BOUNDARY
ACROSS CWA AND YET ANOTHER MORE SHEARED WAVE ENTERS THE AREA TUESDAY
NIGHT.  BEST CHCS TUES NIGHT AGAIN IN SOUTHERN COUNTIES.

UPPER RIDGE BUILDS FURTHER OVER THE ROCKIES WED AND EXPANDS ONTO THE
PLAINS.  THIS SHIFTS STRONGEST SHORTWAVE ENERGY TO THE NORTH.
HOWEVER...WEAK WAVE STILL PROGGED TO ENTER CWA AND BOUNDARY LOCATED
NR NEB/KS BORDER.  WILL INCLUDE AFTN CHCS IN SE CWA IN MOISTURE AXIS
AND IN AREA OF HIGHER CAPES.  WILL KEEP WESTERN COUNTIES DRY WITH
INCREASING MID LEVEL TEMPS WITH BUILDING RIDGE.

IN THE EXTENDED...MODELS CONTINUE TO STRENGTHEN UPPER RIDGE...WITH
BOUNDARY STILL PERSISTENT ACROSS THE AREA.  WILL CONTINUE TO MENTION
TSTM/SHRA CHCS.  LOWS 60S.  HIGHS 85 TO 95.

.GID...NONE.
