Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0120 PM CST Thu Dec 19 2024

Valid 211200Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Synopsis...
A mid/upper-level shortwave trough is forecast to move across
WA/OR/northern CA during the day on Saturday, and eventually
approach the northern Rockies region by early Sunday morning. Very
modest buoyancy (with pockets of MUCAPE around 100 J/kg) and ascent
attendant to the shortwave will support convection with potential
for sporadic lightning flashes and locally gusty winds across
coastal regions of northern CA and OR. At this time, the greatest
relative potential for any lightning activity is expected early in
the forecast period, though shallow convective showers may persist
through much of the day in the wake of the departing shortwave.

Across the central/eastern CONUS, an expansive surface ridge will
result in dry and stable conditions, with negligible thunderstorm
potential.
