Areas affected…Portions of southeastern WY…northeastern CO…and
the far western NE Panhandle
Concerning…Severe Thunderstorm Watch 607…
Valid 210305Z – 210430Z
The severe weather threat for Severe Thunderstorm Watch 607
continues.
SUMMARY…An isolated severe threat continues across mainly western
portions of Severe Thunderstorm Watch 607.
DISCUSSION…Storms have generally weakened this evening along and
just east of the higher terrain in southeastern WY and northeastern
CO. Even with continued low-level easterly upslope flow across this
region, convective inhibition has increased. Convective overturning
from storms earlier this afternoon/evening may have also locally
reduced mid-level lapse rates. Even so, weak to moderate instability
coupled with sufficient shear may continue to support an isolated
severe threat across mainly western portions of Severe Thunderstorm
Watch 607 in the short term. Large hail remains the primary threat.
The potential for clustering of storms later tonight into the
western NE Panhandle appears lower due to a general lack of storm
organization and intensity across southeastern WY as of 03Z.
