Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0733 PM CDT Mon Oct 28 2024

Valid 290100Z - 291200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected tonight.

...01z Update...

Western CONUS upper trough is shifting east early this evening, and
significant mid-level height falls are now spreading across the
lower CO River Valley into the Great Basin. Leading edge of
large-scale forcing appears to be partly responsible for weak
frontal convection that currently extends across eastern NV-northern
UT-central WY. Occasional flashes of lightning may persist with this
frontal activity as the main wind shift sags southeast.

Downstream, low-level warm advection is expected to increase and
focus across the upper Great Lakes later this evening. Both GRB and
MPX soundings exhibited modestly steep mid-level lapse rates, but
profiles have yet to moisten sufficiently and buoyancy remains
negligible. With time, elevated profiles should beco*e more
unstable, and lightning is expected with deeper convection.
