Will go ahead and open a talk thread for today for the high plains area, as there appears some reasonable possibility of severe convection across E CO, W KS, and the panhandles. AFD's in the region are kind of downplaying the threat and seem skeptical of moisture return around the back side of the high. At this hour, instability and theta-e appear to be nosing up the panhandle, and mid-level lapse rates will likely be steepening over the afternoon. W/ upper level impulse approaching from the four corners, be on the lookout for lee cyclogenesis. Some SR helicity areas approaching 200 m2/s2 also encouraging. Probably a fairly marginal setup for tornadic activity, but any lingering vacationers / local chasers may want to monitor this afternoon.
