Areas affected...Eastern Colorado and southeast Wyoming/southern
Nebraska Panhandle
Concerning...Severe Thunderstorm Watch 444...
Valid 050234Z - 050430Z
The severe weather threat for Severe Thunderstorm Watch 444
continues.
SUMMARY...Isolated severe storms remain possible, mainly across
northern Colorado near/east of Denver into northeast Colorado
roughly along/north of I-70.
DISCUSSION...The most severe-favorable environment remains focused
near the Front Range/I-25 corridor generally near Denver, where some
stronger storms persist along/north of I-70. A few of these storms
remain potentially capable of severe hail and/or wind gusts over the
next couple of hours. These eastward persistence into/across the
adjacent plains is a bit uncertain given what appears to be a more
convectively hostile thermodynamic environment with eastward extent.
It is otherwise perhaps worth noting that some short-term guidance
such as recent HRRR runs suggest that a secondary round of stronger
convection could materialize late tonight (after midnight local
time) across northern Colorado/far southeast Wyoming. This would
probably be related to the approach of the shortwave trough/speed
max currently over southeast Idaho. Should this development occur,
residual instability (mostly elevated) and strong shear through the
cloud-bearing layer could potentially support hail.
