....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ALONG THE
CENTRAL ROCKIES FRONT RANGE...

....SUMMARY...
Isolated severe thunderstorms remain possible near the
Colorado/Wyoming Front Range and central High Plains this evening.

....01z Update...

Great Basin upper ridge is gradually building north across the
Interior West early this evening. As a result, northwesterly flow
remains firmly established across eastern WY/CO. Scattered
convection has developed beneath this feature with the eastern-most
thunderstorms noted along the CO Front Range. Latest diagnostic data
continues to depict a narrow corridor of modest instability along
the Front Range from southeast WY into northeast NM. A few robust
thunderstorms are noted along this corridor but MRMS data suggests
any hail with this activity is likely marginally severe at best.
Will maintain MRGL Risk for isolated-scattered thunderstorms this
evening as cloud-layer shear is more than strong enough for
organized updrafts.

Southeast Lower Michigan: Scattered thunderstorms have developed
along the cold front across southern ON into southeast MI. While
gusty winds, and perhaps some marginally severe hail, may be noted
with these storms for the next hour or so, this activity will
quickly shift into ON. Severe probabilities will not be introduced
for these reasons.
