Large shortwave trough remains in the western CONUS, putting KFTG CWA in southwest flow. Surface low in western Colorado is bringing upslope flow.

16z GOES LAP stability indices indicate CAPE is increasing in far NE CO where the cloud deck has eroded over the past couple of hours. Clearing has been slow, however, per the super rapid scan visible imagery.

Dew points are in the mid-50s across the Front Range as of 18z, approaching 60F to the east.

KDNR sounding indicates a large cap at about 700mb, but 700-500mb lapse rate is 7.9C/km. EML is at about 700-550mb. 0-6km shear is favorable for rotation/supercells (~40-50 kt) for storms once they actually do fire.

MUCAPE 2000-3000 J/kg, but CIN is still at about 500-750.

Small puffs of cu developing in the mountains, but they have not grown notably over the past hour.

SWODY1 has the FTG CWA in an ENH risk.
