Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0234 AM CDT Sun Jul 30 2023

Valid 021200Z - 071200Z

....DISCUSSION...
Mean upper ridging will persist across the western half of the CONUS
with troughing in the east for much of the Day 4-8 period. As a
result, modest northwesterly deep-layer flow will continue across
portions of the Midwest. An upper shortwave trough over western
Canada will develop east/southeast toward Ontario/Quebec and the
Great Lakes vicinity. This may bring some chance for severe
thunderstorms to parts of the Great Lakes region around the Day 5 or
6 time frame. However, stronger surface cyclogenesis and large-scale
ascent associated with the mid/upper shortwave trough will mostly be
focused north of the international border. Overall, severe potential
during the Day 4-8 period appears too low/uncertain to include 15
percent probability delineations at this time.
