Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0341 AM CDT Fri Jul 04 2025

Valid 071200Z - 121200Z

....DISCUSSION...
An upper ridge will gradually build over the Southwest while mainly
zonal mid-level flow persists over the northern CONUS through next
week. A relatively nebulous surface pattern will be the norm through
the extended range. Rich low-level moisture will overspread the
CONUS east of the Rockies Days 4-8/next Monday-Friday, supporting
scattered thunderstorm development over much of the Great Plains
into the MS Valley, and the Southeast into the Northeast. The best
chance for at least isolated strong to potentially severe storms in
the upcoming week would be across the north-central CONUS. Here, the
low-level moisture will advect northward beneath relatively cooler
temperatures and modest northwesterly flow/shear aloft. However,
given the nebulous and weakly forced environment, confidence is too
low to delineate severe probabilities over the north-central U.S.
for any given day.
