Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1115 AM CST Fri Dec 23 2022

Valid 241200Z - 251200Z

....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected over the contiguous United States on
Saturday.

....Synopsis...
An expansive upper-level trough will extend from eastern Canada
south over much of the eastern U.S. on Saturday as upper-level
ridging dominates across much of the western states. A low-amplitude
shortwave trough will move onshore across the Pacific Northwest
Saturday accompanied by rain showers. NAM forecast soundings depict
minimal elevated instability (less than 200 J/kg) near the coast,
and a sporadic lightning strike will be possible in this area as
precipitation moves onshore. Overall, the risk remains too low to
introduce thunder probabilities with this outlook.  Elsewhere,
surface high pressure and a very cold/stable air mass will preclude
thunderstorm development across the CONUS on Saturday.
