Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1110 AM CST Fri Dec 20 2024

Valid 211200Z - 221200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Saturday.

....Synopsis...
An upper-level ridge centered near the Continental Divide will
translate slowly eastward through the day as a strong, compact,
negatively-tilted mid-level trough moves into the Pacific Northwest.
Across the eastern CONUS a trough will persist on Saturday with dry,
offshore flow at the surface. The lack of low-level moisture will
limit any thunderstorm potential across most of the CONUS. The only
exception will be across the Oregon/northern California coasts where
cooling mid-level temps over the relatively warmer ocean waters may
result in some shallow instability and the potential for a few
thunderstorms. The strong low-level jet (50 to 70 knots from 12Z to
18Z Saturday along the Oregon/northern CA coast) may result in some
gusty winds, even where lightning is not present. However, overall,
limited instability should mitigate any severe weather potential.
