   The severe weather threat for Severe Thunderstorm Watch 361
   continues.

   SUMMARY...The severe risk continues across WW361 with the risk of
   damaging winds and hail. Storm coverage could increase this evening
   though storm evolution is uncertain.

   DISCUSSION...As of 2330, UTC regional observations showed widely
   scattered clusters of strong to occasional severe storms ongoing
   across parts of eastern/southeastern CO. Thus far, severe storm
   coverage has remained somewhat limited within a modifying
   post-frontal upslope flow regime. Still the environment remains
   broadly favorable for damaging gusts and hail with ~1000 J/kg of
   MLCAPE and 40-50 kt of effective shear over much of the watch areas.

   Later this evening into tonight, additional storm development will
   remain possible along the I-25 corridor. Numerous weak updrafts are
   present over the mountains and eastern foothills of the Rockies.
   Recent hi-res guidance and some observational trend suggest a few of
   these updrafts may eventually move east and mature with the onset of
   additional forcing from the nocturnal low-level jet. While
   conditional, severe storm coverage may increase in the next couple
   of hours and into the early overnight within the aforementioned
   favorable environment. Should this occur, hail and damaging winds
   appear likely, especially over northern and central portions of
   WW361. However, significant uncertainty in storm evolution remains.
