Area forecast discussion, Aug 21, 3:04 PM CDT, 6 hours 38 minutes before
SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
304 PM CDT TUE AUG 21 2001

THE HEAT IS ON ACROSS THE SOUTHERN CWFA WITH DRY SOUTHWEST
FLOW. WEAK TROF IN WESTERN NEBRASKA COULD FOCUS FOR SOME HIGH
BASED CONVECTION...BUT CIN IS HOLDING FIRM. WARM ADVECTION
REGIME NOT AS IMPRESSIVE AS LAST NIGHT. THOUGH THE LIKELIHOOD OF
RAIN IS SLIM TONIGHT...IT DOESNT APPEAR TO BE NONE. BELIEVE AT
LEAST SMALL POP STILL IN LINE. AVN AND ETA BOTH TRY TO SLIDE FRONT
SOUTH WEDNESDAY. SOME LINGERING EARLY MORNING SHOWERS MAY HANG ON
SOUTHEAST ZONES. WILL HOLD ON TO WARMER TEMPERATURES PER RECENT
TRENDS DESPITE FRONT TRYING TO SLIDE SOUTH.

THE MOST INTERESTING ITEM ON THE AGENDA IS THE WAVE PASSING LAS
VEGAS NOW...AND WHICH IS FORECAST TO MOVE TO THE KS/CO/NE AREA
BY THURSDAY AFTERNOON NOON. SOME DIFFERENCES IN EXACT HANDLING
OF WAVE MOVEMENT...BUT GOOD SYNOPTIC SCALE LIFT WITH SYSTEM
WILL DRAMATICALLY INCREASE RAIN CHANCES LATER THURSDAY. HPC
QPF ON THE WET SIDE...AND AGREE ENOUGH WITH THAT TO HOIST SOME
HEFTY POPS. LOTS OF CLOUDS TO KEEP TEMPERATURES DOWN SOME.
NO EARTH SHATTERING CHANGES BEYOND THAT.

.GID...NONE.

SEVERE WEATHER OUTLOOK - SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS
NATIONAL WEATHER SERVICE HASTINGS NE
928 PM CDT TUE AUG 21 2001

SPOTTER ACTIVATION MAY BE NEEDED TONIGHT ACROSS SOUTH CENTRAL
NEBRASKA AND NORTH CENTRAL KANSAS.

A WEAK UPPER LEVEL DISTURBANCE LIFTING OUT OF NORTHEAST COLORADO
COMBINED WITH AN INTENSIFYING LOW LEVEL JET HAS ALLOWED A LINE OF
STRONG TO SEVERE STORMS TO DEVELOP THIS EVENING ALONG THE
KANSAS NEBRASKA BORDER INTO NORTHWEST KANSAS. CONSIDERABLE
INSTABILITY EXISTS ACROSS SOUTH CENTRAL NEBRASKA AND NORTH CENTRAL
KANSAS...WHICH HOWEVER WAS TEMPERED BY THE EXISTENCE OF A MID LEVEL
WARM LAYER WHICH HAD SUPPRESSED ANY CONVECTIVE DEVELOPMENT EARLIER
THIS EVENING.

IF THIS LINE OF STORMS CAN CONTINUE TO ORGANIZE AND HOLD TOGETHER...
THERE WOULD BE A RISK OF SCATTERED SEVERE STORMS ALONG AND SOUTH
OF A CENTRAL CITY TO LEXINGTON LINE. DAMAGING WINDS AND LARGE HAIL
WILL BE THE PRIMARY THREATS FROM THESE STORMS.

STAY TUNED TO NOAA WEATHER RADIO...OR YOUR FAVORITE LOCAL MEDIA
OUTLET FOR LATER STATEMENTS...AND POSSIBLE WATCHES OR WARNINGS.
