SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1235 AM CST Sun Dec 21 2025 Valid 221200Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Monday. ...Synopsis... Model guidance continues to show an upper-level ridge and quiescent conditions influencing weather across much of Lower 48 states on Monday. A mid-level shortwave trough will move from the eastern Pacific into WA and British Columbia during the period. Increasingly cool mid-level temperatures will support pockets of scant instability near the Pacific Northwest coast. Widely scattered showers and perhaps a few low-topped thunderstorms may develop along the immediate coast. Farther southeast along the lower coast of TX within a seasonably moist airmass, weak convection may develop but negligible forcing will likely limit convective potential with this activity. ..Smith.. 12/21/2025
