SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
225 PM CDT SUN APR 22 2001

...IMMEDIATE CONCERN IS OF COURSE SEVERE TSTMS AND THEN ATTENTION
TURNS TO SNOW POSSIBILITIES FOR TONIGHT...

18Z SATELLITE IMAGERY AND PROFILERS SHOWS MODELS LOOKING OKAY AS
FAR AS POSITION OF 500 LOW. 95 KT 500 MB JET AT GRANADA PROFILER AT
17Z. NICE DRY SLOT WORKING FROM WESTERN KANSAS INTO SW NEB. AT SFC...
THE WARM FRONT HAS LIFTED NORTH THROUGH MOST OF CWA WITH ODX AND LEX
STILL ON THE COOL SIDE OF THE BNDRY. GRI TEMP JUMPED 12 DEG IN 14
MINUTES AS FRONT MOVED N AROUND 17Z.  AUTO OBS AT ODX REPORTING
SNOW BUT CALLS TO HUMANS IN THAT AREA CONFIRM LIGHT RAIN ONLY. SFC
LOW IN SE COLORADO...PROJECTED TO TRACK ENE AND BE OVER LNK BY
MIDNIGHT.

SETUP STILL LOOKING PROMISING FOR SEVERE INTO THIS EVENING AS SYSTEM
LIFTS INTO OUR AREA. QUESTION THEN BECOMES HOW MUCH COLD AIR CAN
GET INTO REGION BEFORE PRECIP MOVES OUT. MAY GET AN INCH OF SNOW OUT
WEST AND NW BUT BELIEVE MOST OF PRECIP LIFTS OUT WITH ONLY MINIMAL
WRAP AROUND.  FORECAST SOUNDINGS USING MESO ETA FOR LEX WOULD CHANGE
FROM RAIN TO SNOW BTWN 03 AND 06Z.  IN GRI AREA TEMPS WOULD DROP
COLD ENOUGH FOR SNOW BY 09Z.

OTHER CONCERN IS THE WINDS. NEAR ADVY CRITERIA MANY LOCATIONS AND
WINDS TO KEEP UP AS LOW PASSES. GRAD STAYS TIGHT AS LOW MOVES ACROSS.
WILL PROBABLY GO AHEAD AND ISSUE ONE FOR THE WESTERN AND CNTR
L PARTS
OF THE CWA AND LATER SHIFTS CAN REISSUE AS THE LOW MOVES.

.GID...WIND ADVISORY UNTIL MIDNIGHT FOR AREAS WEST OF CENTRAL CITY
TO GRAND ISLAND...AND SOUTH TO INCLUDE ALL OUR KS CWA.

SEVERE WEATHER OUTLOOK - SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS
NATIONAL WEATHER SERVICE HASTINGS NE
1120 AM CDT SUN APR 22 2001

...SPOTTER ACTIVATION WILL LIKELY BE NEEDED THIS AFTERNOON AND
EARLY EVENING...

SEVERE THUNDERSTORMS ARE FORECAST TO CROSS PARTS OF SOUTH CENTRAL
NEBRASKA AND NORTH CENTRAL KANSAS THIS AFTERNOON AND EVENING.
DAMAGING WINDS...LARGE HAIL...AND TORNADOES ARE POSSIBLE.

A WARM FRONT FROM OMAHA TO MCCOOK IS FORECAST TO DRIFT NORTH
AT A SLOW RATE THIS AFTERNOON.  THE FRONT WILL LIKELY SERVE AS
THE PRIMARY FOCUS FOR SEVERE STORMS AND POSSIBLY TORNADOES. AN
INTENSE UPPER LEVEL SYSTEM OVER COLORADO WILL PROVIDE LIFT OVER THE
FRONT AND INCREASE THE THREAT.

A DRY LINE IS PREDICTED TO MOVE FROM EASTERN COLORADO INTO KANSAS AND
SOUTHERN NEBRASKA THIS AFTERNOON.  IT WILL LIKELY TEAM WITH THE UPPER
SYSTEM TO SPAWN A SQUALL LINE OF SEVERE STORMS SOUTH OF THE SURFACE
FRONT INTO KANSAS. THIS LINE OF STORMS WILL LIKELY PRODUCE DAMAGING
STRAIGHT WINDS...AND AN ISOLATED TORNADO MAY ALSO DEVELOP ALONG THE
LINE.

THE THREAT FOR SEVERE WEATHER SHOULD END AROUND SUNSETZ.
