Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0401 AM CDT Wed Jul 31 2024
Valid 031200Z - 081200Z
...DISCUSSION...
The extended period will begin with a large amplitude upper-level
ridge across the western CONUS. This ridge will gradually breakdown
on Sunday and Monday with more of a flat ridge by the middle of next
week. Persistent northwesterly flow across the Northern Plains/Upper
Midwest during the extended forecast period may result in some
isolated severe weather threat. However, moisture in the Northern
Plains will lack a Gulf of Mexico connection and thus, will likely
be somewhat low quality, at least initially.
Early next week, as lee troughing returns to the Plains and the
low-level jet strengthens, the severe weather threat may increase
somewhat. Overall, upper-level ridging and no clear strong troughs
during the extended period, suggests any severe weather threat that
materializes will likely remain somewhat localized this weekend and
early next week.
