Areas affected...Parts of east-central Colorado

Concerning...Severe Thunderstorm Watch 489...

Valid 062354Z - 070100Z

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-35 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-35 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.
