   CORRECTED FOR GEOGRAPHIC DESCRIPTION

   The severe weather threat for Severe Thunderstorm Watch 489
   continues.

   SUMMARY...Large hail and severe wind gusts remain possible along and
   east of the I-25 corridor in Colorado -- within Severe Thunderstorm
   Watch 489. A local southward extension of the watch may be
   warranted.

   DISCUSSION...A couple organized clusters/supercells are tracking
   slowly southeastward along and east of the I-25 corridor in CO, with
   a recent report of 2-inch hail. VWP and mesoanalysis data show a
   long/straight hodograph (around 40 kt of effective shear), which
   combined with steep deep-layer lapse rates, should support the
   maintenance of these storms with southeastward extent. Large hail
   and severe wind gusts are the primary concerns. It is possible that
   the southern supercell tracks south-southeastward out of Severe
   Thunderstorm Watch 489, and a local extension of the watch may be
   warranted here.
