Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0703 AM CDT Fri Apr 08 2022

Valid 081300Z - 091200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today or tonight.

...Synopsis/Discussion...
A highly amplified flow pattern will exist over the CONUS and nearby
Canada through tonight, with severe storms not expected owing to the
general prevalence of limited moisture/instability.

An upper trough centered over the Great Lakes/Ohio Valley will shift
eastward through tonight. While moisture will be limited to the west
of a cold front now over the western Atlantic, cold mid-level
temperatures and diurnally steepening lapse rates will allow for the
possibility of isolated low-topped thunderstorms late this morning
through afternoon across the Ohio Valley and northern/central
Appalachians, and near the coastal Mid-Atlantic through early
evening.

A secondary upper trough is forecast to move inland over the Pacific
Northwest today. Related forcing for ascent and orographic lift may
support isolated lightning flashes from the Washington/Oregon coasts
to the northern Rockies, primarily this afternoon.
