Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0212 AM CDT Fri Jul 15 2022

Valid 171200Z - 181200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The potential for organized severe thunderstorms will likely remain
limited on Sunday across the contiguous United States.

...Synopsis...
A large mid-level anticyclone will reside over the Four Corners on
Sunday.  A mid-level low will slowly move east from the WA
coast/Vancouver Island into the Pacific Northwest.  A weak and broad
mid-level trough will move east across the southern Great Lakes/OH
Valley, and a low-amplitude, mid-level shortwave trough will move
across New England during the day.  The surface pattern will feature
a myriad of weak, diffuse boundaries, one of which will move across
the mid MS Valley into the OH Valley.  Scattered
showers/thunderstorms will likely acco*pany the disturbance over the
OH Valley into the Appalachians.  However, generally weak flow will
lead to disorganized clusters of storms during the afternoon/early
evening.  Elsewhere, a couple of strong storms cannot be ruled out
across parts of New England.  Farther west, a few strong to locally
severe gusts could occur over parts of the Desert Southwest and in
parts of the northern Rockies into the plains of Montana.
Uncertainty remains sufficiently high, precluding the introduction
of small 5-percent severe areas at this time.
