MODELS SIMILAR KEEPING 500 TROUGH OVER WESTERN U.S. BUT THIS IS WHERE SIMILARITY ENDS. BY 48 HOURS...SIGNIFICANT SHORTWAVE EJECTS OUT OF TROUGH WITH TIMING DIFFERENCES BETWEEN MODELS. NGM HAS VORT MAX OVER NW KS WHILE ETA HAS VORT FURTHER SOUTH AND WEST OVER SE CO. 18Z SFC MAP STILL DID NOT SHOW LEE SIDE TROUGH YET WITH WEAK SFC HIGH IN SW NEB AND SOUTHEAST WINDS ALONG FRONT RANGE. KCYS AND KFTG RADAR SHOWING CONVECTION FIRING ON MOUNTAINS SHOWING MOVEMENT NORTHEAST. THUNDERSTORM CHANCES LOOK DECENT TONIGHT IN WEST...BUT NOT AS CONFIDENT AS I WAS YESTERDAY WITH HIGH POPS. 700 AND 850 THTE RIDGES BUILD INTO WESTERN NEBRASKA TONIGHT AND MOVE ACROSS CWA AND THEN BUILDS BACK TO THE WEST AGAIN AT 48 HOURS. ISENTROPIC LIFT ON I290 THROUGH I305 SURFACES OCCURS OVERNIGHT ACROSS CWA AND THERE ALSO IS SOME UPSLOPE WHICH WILL AID IN PRECIP. AIRMASS GETTING UNSTABLE WITH CAPES OVER WEST PROGGED TO BE IN 500-1000 J/KG AT 00Z TONIGHT AND LITTLE CIN.

FOR WEDNESDAY...MOISTURE GETS SHUNTED OFF TO EAST WITH SOME DRYING IN WEST AND LIKE ETA MODEL FOR 850 DEW POINTS BETTER THAN NGM BECAUSE NGM LOOKS WAY DRY WITH 0-2 DEW POINTS OVER CWA AT 00Z THU WHILE ETA SHOWS 2-14 RANGE WITH HIGHEST DEW POINTS IN NORTHEAST CWA WHERE MOST UNSTABLE AIR IS.
