SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1255 AM CST Thu Dec 18 2025 Valid 191200Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms may occur over the Mid Atlantic and Northeast early Friday, and in the Pacific Northwest Friday afternoon through Friday night. ...Discussion... A line of thunderstorms is expected along a strong cold front extending from eastern New York to eastern North Carolina Friday morning. This line of storms is expected to be mostly elevated from Pennsylvania northward. From northern Virginia southward, some weak instability is possible ahead of the front as upper 50s to near 60s dewpoints advect northward. Forcing will be weaker farther south, and 00Z CAM guidance supports this with a more broken line of storms that far south. If a more consolidated, strong frontal band can continue where the near 60s dewpoints are present, a few isolated strong wind gusts may occur for a few hours in the morning before the front moves offshore. In the wake of this front, benign conditions are expected across most of the CONUS on Friday. Scattered thunderstorms are possible across western Washington and far northwest Oregon, but this thunderstorm activity should remain weak. ..Bentley.. 12/18/2025
