NATIONAL WEATHER SERVICE HASTINGS NE
255 PM CDT SAT APR 21 2001

PRIMARY CHALLENGES WITH THIS PACKAGE ARE DEVELOPMENT OF
PRECIPITATION TONIGHT THROUGH SUNDAY...AND COLD INTRUSION IN WAKE OF
UPPER SYSTEM SUNDAY NIGHT THROUGH MONDAY.

STAGE APPEARS SET FOR MAJOR OUTBREAK OF SEVERE WEATHER ALONG
SURFACE BOUNDARY ACROSS KANSAS THIS EVENING.  SATELLITE PLACES UPPER
LOW OVER ARIZONA WITH MODELS IN GENERAL AGREEMENT SENDING IT
TO SOUTHEAST COLORADO SUNDAY MORNING.  LESS SIDE SURFACE LOW AND
INCREASING LOW LEVEL WINDS SHOULD PUSH FRONT NORTH
TO NEAR THE KS/NE LINE BY DAWN. H85 JET, DYNAMIC LIFT
AHEAD OF UPPER LOW, CONVERGENCE ALONG FRONT AND ISENTROPIC LIFT
SHOULD YIELD WIDESPREAD CONVECTION ACROSS GID CWFA LATE TONIGHT
THROUGH MUCH OF SUNDAY.  HIGH MOS POPS LOOK APPROPRIATE.

EXIT OF UPPER SYSTEM LEAVES GID CWFA IN STRONG COLD ADVECTION IN ITS
WAKE BY SUNDAY NIGHT.  PREFER ETA/MESOETA SOLUTION ON STRENGTH OF
COLD AIR.  NGM AND AVN HAVE TRADITIONALLY BEEN TOO WEAK WITH
SIMILAR COLD AIR OUTBREAKS.  WILL SIGNIFICANTLY UNDERCUT MOS
TEMPERATURES SUNDAY NIGHT AND MONDAY. PRECIPITATION IN DEFORMATION
ZONE WEST OF UPPER SYSTEM EXPECTED TO EXIT BY MONDAY MORNING WITH
ETA AGAIN THE PREFERRED MODEL.  COLD ADVECTION LIKELY TO HOLD
CLOUDS WELL INTO MONDAY.

BENIGN PATTERN WITH UPPER RIDGING TO SET IN FOR THE REMAINDER OF THE
COMING WEEK PER MRF.
