...FORECAST PROBLEM WL BE CHC OF PCPN THRU PD WHICH DEPENDS ON TIMG
UPR LVL DISTURBANCES AND FRONTAL POSN...

BASED ON INITIALIZATION...SATL...AND CURRENT TRENDS...WL PREFER THE
ETA IN GENL BUT IT HAS ITS PROBLEMS. ETA PEGGED CURRENT FRONTAL
TRENDS AND POSN. BASICALLY THE FRONT ATTM SPLITS OUR CWA INTO A NW
AND SE HALF. SATL SHOWG CU DVLPG ALG AND EAST OF A LINE FM NR MCK TO
GLD TO NR CHEYENNE WELLS.

ALSO ETA PICKED UP CURRENT 700 MB VORT MAX NOW MOVG INTO SRN CO.

UPR AIR ANAL SHOW TROPICAL EXTENDG FROM NM INTO CO. CONVECTION
CURRENTLY FIRING WITH THESE FEATURES OVR WRN AND CNTRL CO. ETA
APPEARS A LTL DRY IN THE ABV AREA. PLUS NONE OF THE MODELS REALLY
HAVE THE SFC DPS CORRECT AS WELL...AND ARE TOO DRY.

NOT ONLY IS ETA DOING FINE ON FRONTAL POSN...BUT IS ALSO GETTING SFC
LOW POSN OVR SE CO FINE AS WELL...HWVR IT LOWERS ITS PRESSURES TOO
MUCH. FRONT LOOKS TO REGRESS TO NE/KS BORDER AND THEN STAYS IN THAT
GENL AREA FOR MOST OF THE TIME. ETA HAS A STRONG COUPLET OF 700 AND
500 OMEGA BEGINNING TMRW AFTN INTO TMRW NIGHT AS ANOTHER VORT MAX
COMES IN FROM THE SW.

CONSIDERING UNCERTAINTY OF FRONTAL POSN AND TIMG OF WK UPR LVL
FEATURES AND ABV REASONG...WL KEEP A SLGT CHC TO CHC POPS OVR ENTIRE
AREA THRU PD. GREATEST POPS WL BE OVR NRN AND ERN LOCATIONS AND TON
AND TMRW NIGHT DUE TO EXPECT FRONTAL POSN AND BEST OMEGA. NGM WAS
INITD TOO COOL AND TAKES EVERYTHING TOO FAR SOUTH. THIS SPELLS GOING
ABV NGM MOS FOR THE MAXES. ALSO WITH HIR DPS...MSTR LVLS...AND CLD
COVER...WL GO ABV NGM MOS AS WELL FOR MINS.
