...TSTMS AND AMOUNT OF RAIN IS MAIN CHALLENGE WITH THIS FCST...

MAIN CONCERN FOR CWA IS THIS EVE AND TONIGHT.  CONVECTION FIRING
UP OVR WY AND CO FOOTHILLS ATTM DUE TO AFTN HEATING AND UPSLOP FLOW.
STRONG SHORTWAVE INDICATED MOVG INTO NE WY AND HI PLAINS WHICH SHOULD
ENHANCE ACTIVITY NW OF FA THIS AFTN.  ADAPS ALREADY SHOWING BOUYANT
AMS OVR MUCH OF REGN THIS AFTN WITH NO CAP.  TIMING OF SHORTWAVE
(WHICH BOTH THE NGM/ETA VRY SIMILAR ON)...CONVERGENCE OF Q-VECTORS
IN THE 700-300 LAYERS AND STRONG LOW LVL MSTR CONVERGENCE SUGGESTS
TSTMS WL MOVE OVR FA BY 00Z.  FOLLOWING THE THETA-E RDG OVR THE HI
PLAINS WOULD PUT SW NEBRASKA AND NW KANSAS IN FAVORED TSTM AREAS.
LOOKING AT FZL AND WBZ FROM MORNING SOUNDINGS...HVY RAIN AND HAIL
LOOK TO BE THE MAIN THREATS.

ETA/NGM CONVECTIVE PCPN FIELDS AND UVVS OVR THE FA POINT TO ACTIVE
NIGHT WITH WIDESPREAD ACTIVITY UP TIL 12Z SUNDAY...THEN DESCENDING
MOTION FCST.  UPSLOP FLOW SHOULD CONTINUE EARLY BUT FEEL SUBSIDENCE
AND MIXING WL DIMINISH CLOUD COVER BY AFTN OVR MOST AREAS.  NGM
TIME-HGT CROSS XCTNS SHOWS MID LVL MSTR TO STAY OVR CWA THRU THE DAY
SUNDAY.  PREFER ETA MDL IN DRYING OUT AMS SUN/SUN NGT WITH BUILDING
HGTS ALFT.  REST OF FCST LOOKS FAIR WITH WARMING TEMPS.
