Valid 280316Z - 280515Z

The severe weather threat for Severe Thunderstorm Watch 311
continues.

SUMMARY...Scattered strong/severe storms will spread across mainly
the northern portions of ww311.

DISCUSSION...High-plains convection has evolved into a line segment,
roughly 50mi in length, as it propagates across northwestern
portions of the watch. Earlier, winds gusted to 50kt at Burlington
CO with this squall line. Latest observational data suggest earlier
surface boundary that was lifting north across southwest KS has
advanced to near the I-70 corridor, and warm advection is now
focused north of this wind shift. In addition, LLJ is beginning to
strengthen into this zone which should aid longevity of convection
as it spreads east into the early morning hours.
