Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0349 AM CDT Fri Jul 19 2024

Valid 221200Z - 271200Z

...DISCUSSION...
The overall pattern will not change much during the Day 4-8 period.
An upper ridge over the western states will gradually shift east
into the Plains around Days 7-8/Thu-Fri. Meanwhile, a mean upper
trough will persist across the eastern U.S., with some eastward
progression of an embedded shortwave trough from the upper Great
Lakes toward the Northeast around mid to late week. Mid/upper flow
will remain modest. Given an overall stagnant upper pattern, a
somewhat nondescript surface pattern lacking any appreciable
cyclogenesis is forecast. While a typically moist and unstable
summertime airmass will be in place east of the Rockies,
severe-thunderstorm chances appear low.
