Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0740 PM CDT Sun Sep 03 2023

Valid 040100Z - 041200Z

....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE NORTHEAST GREAT BASIN INTO WESTERN WYOMING...

....SUMMARY...
Gusty winds may accompany convection across parts of northeast Utah
into extreme western Wyoming for the next few hours.

....01z Update...

Pronounced short-wave trough is ejecting across the western Great
Basin early this evening. Leading edge of large-scale ascent appears
to be associated with convection that is now spreading across
southeast ID, trailing across northwest UT. 00z sounding from SLC
has yet to be overturned with 40F surface temp/dew point spreads and
SBCAPE around 800 J/kg. Adequate deep-layer flow/shear are present
across this region for the maintenance of organized convection, but
appreciable buoyancy is now reduced to a small corridor of the
northeastern Great Basin into extreme western WY. Gusty winds may
accompany some of this activity for the next few hours, but overall
trends suggest the severe threat will be limited due to limited
instability.
