Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0245 AM CDT Fri Aug 26 2022

Valid 291200Z - 031200Z

...DISCUSSION...
...Day 5/Tue - Lower Great Lakes/Northeast...

An upper trough over the upper Great Lakes will pivot east/northeast
into portions of the Northeast on Tuesday. A seasonally moist
airmass and increasing southwesterly flow will overspread the region
ahead of an eastward-advancing surface cold front. Forecast guidance
currently develops quite a bit of precipitation across the region
early in the period, limiting stronger destabilization. Isolated
strong storms could occur across parts of OH/PA/NY, but confidence
is too low to include severe probabilities at this time.

...Elsewhere...

The southern/western extent of the aforementioned surface cold front
will drift southward across the southern Plains and the TN Valley
vicinity mid to late next week. This could beco*e a focus for strong
storms, but deep-layer flow is expected to remain weak, limiting
vertical shear, which would favor poorly organized thunderstorm
clusters. Overall severe potential appears low for the much of the
rest of the CONUS, (outside of low-end potential on Day 5) for the
extended period.
