SHRT TERM DISCUSSION:  LOOKS LIKE POSSIBLE MCS FORMATION ACROSS NRN
PTN OF THE CWA IS THE MN CHALLENGE TNGT.  PREFER TDAS ETA THRU 24
HRS...BUT NO GRIDDED DATA WAS AVAILABLE FM THIS MODEL ATTM.
HWVR...ETA AFOS GRAPHICS THRU TNGT INDC ETA TO BE THE ONLY MODEL
FAIRLY CNSTNT WITH HANDLING OF SHRT WV CURRENTLY INDCD NEAR WHERE
WY...UTAH AND CO MEET. ETA CONTS TREND OF PAST COUPLE OF RUNS OF
TAKING THIS SHRT WV ACROSS THE NRN PTN OF THE CWA.  WITH INCRNG
DWPNTS THIS EVE ACROSS THE CWA AS SFC WNDS BECOME SE AHEAD OF DVLPG
LEE-SIDE SFC TROF...FEEL TSTM DVLPMT IS A GD BET...SPCLY N UNDER
UPR DYNAMICS.  HV WEIGHTED HIER POPS N ACCORDINGLY.

CAPES OF 3000 TO 3500 AND SFC-3KM HELICITIES OF ABT 200 FM LBF
MODIFIED MORNING SOUNDING...STRONGLY HINT AT SVR TSTMS TNGT.
ALTHOUGH...INITIAL DVLPMT MAY BE SUPERCELL...DEVELOPING LLJT
AND STRONG DRCTNL SHEAR IN THE LOWEST 3KM SUGGEST MCS...WITH
POSSIBLE BOW ECHO EVOLUTION...SPCLY FOR NE COUNTIES.  H7 +10 TO
+12 THERMAL RIBBON INDCS A NW-SE MOTION OF SVR STMS AND COMPLEX.

OTRW...TRIED TO TM CLDS AND WNDS TNGT WITH ESTIMATED MOVEMENT OF
TSTMS AND LEE-SIDE TROF.  OTRW...ACCEPTED FWC LOWS.  ATTM...FEEL FOG
IS NOT LKLY AS SFC WNDS SHOULD GAIN A WRLY COMPONENT BEHIND THE
COMPLEX.  SEE CCF PTN FOR DETAILS.

LONG TERM DISCUSSION:  NO ETA DATA BEYOND 24 HRS AND ONLY HAD NGM
GRIDDED DATA TO LOOK AT.  SEEMS MAIN PROBLEM IS FOLLOWING AND
TIMING OF EACH S/WV IN FLOW ALF. THE MORE ZONAL FCST PATTERN LEAVES
THE HI PLAINS OPEN FOR CONVECTION.  NGM/AVN SIMILAR WITH LEE-SIDE
TROF OVR FA BUT DIFFER ON UPPER LVL FEATURES THRU TUESDAY NGT.  NGM
STILL TRYING TO BRING MORE ENERGY IN FROM THE SW LATER TUE WITH
500MB DIFFLUENT FLOW OVR HI PLAINS.  VVELS NOT VRY IMPRESSIVE BUT
RISING MOTION OVR LEE TROF...STRONG SFC HEATING AND WEAK
PERTUBATIONS ALF SHOULD GENERATE WIDELY SCT TO SCT TSTMS.
COULD BE MORE OF A NOCTURNAL EVENT JUST E OF CWA DEPENDING ON
TIMING.  THCKNSS VALUES AND 850 TEMPS POINT TO VRY WARM DAYS AHEAD.
