POPS AND TEMPS...PLUS WILL MCS OUTFLOW IMPACT TEMPS ARE THE MAIN
QUESTIONS FOR THIS PACKAGE.

HAVE LEANED HEAVILY ON ETA FOR THIS PACKAGE DUE TO BEST
INITIALIZATION AND 18Z SFC VERIFICATION.  AVN CLOSE ON MASS
FEATURES...BUT TOO MOIST AT MID LEVELS.

FRONTAL BOUNDARY INTENSIFYING FROM NEAR SCOTT CITY NORTHEAST INTO
SOUTH CENTRAL NEBRASKA...WITH SOME MOISTURE POOLING ALONG IT.  ETA
PROGS MINIMAL MOISTURE ADVECTION ABOVE BOUNDARY LAYER...BUT WITH
GOOD SHALLOW MOISTURE LAYER ON SURFACE WITH VERY WARM TO HOT TEMPS
ALONG WITH WEAK DYNAMIC...WILL INCORPORATE 20 POPS ALONG NORTH EDGE
OF CWFA.

BOUNDARY PERSISTS THROUGH PERIOD FOUR...AND POPS CONTINUE IN SAME
GENERAL AREA.  TEMPS LOOK TO REACH 90S EVERYWHERE EXCEPT NORTH OF
BOUNDARY...BUT MIDDLE 80S STILL LOOK REACHABLE DESPITE EAST UPSLOPE
FLOW.

A BETTER ORGANIZED CHANCE FOR POPS FRIDAY NIGHT...BUT SOUTHERN PART
OF CWFA LOOKS TOO DRY FOR CONVECTION.

SATURDAY LOOKS LIKE A CLASSIC WARM DAY WITH SOUTHWEST TO WEST WINDS
AT ALL LEVELS PUSHING COOLER AND MORE HUMID AIRMASS AWAY FROM AREA.
WITH TEMPS RUNNING 15 TO 20 DEGREES ABOVE NORMAL SOUTH OF BOUNDARY
FEEL THAT GUIDANCE LEANING A BIT TOO HEAVILY TO CLIMATOLOGY...AND
WILL BUMP MAXES ABOVE IT.

EXTENDED DISCUSSION FROM NCEP LOOKS GOOD AND WILL NOT DEVIATE.

.GLD...NONE
