Areas affected...Southeast Wyoming...southern Nebraska
Panhandle...Front Range into northeast Colorado
Concerning...Severe Thunderstorm Watch 428...
Valid 172025Z - 172200Z
The severe weather threat for Severe Thunderstorm Watch 428
continues.
SUMMARY...Severe wind gust potential increasing just east of the
I-25 corridor and along I-80 in southeast Wyoming and the Nebraska
Panhandle. How far east this activity can maintain intensity is not
clear.
DISCUSSION...Linear convection has increased in intensity east of
Cheyenne and along the I-25 corridor. The most organized wind
signal, per KCYS velocity data, is moving roughly along I-80 east of
Cheyenne. A 69 mph wind gusts was measured with this activity.
Additionally, KFTG is showing a modest increase in wind potential
just east of the I-25 corridor. Areas of the Nebraska Panhandle into
northeast Colorado did receive longer periods of insolation this
afternoon. Farther east, outflow from morning convection has
modified a small degree. While severe wind gusts will become more
probable in the short term, the eastward extent of this threat is
not clear given at least pockets of MLCIN remaining.
