SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1222 AM CST Wed Dec 11 2024 Valid 121200Z - 131200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Thursday. ...Synopsis... In the wake of a strong shortwave trough moving into the Canadian Maritimes, a mid/upper cyclone is forecast to progress from the Ontario/Quebec border vicinity eastward through Quebec on Thursday. Strong mid-level flow throughout the base of this cyclone is expected to extend from the northern/central Plains through the Northeast. Even with these strong dynamics, extensive surface ridging is expected from the northern Plains into much of the eastern CONUS, promoting dry and stable conditions. Consequently, no thunderstorms are anticipated. Farther west, a low-amplitude shortwave trough is expected to progress across the Great Basin into the Four Corners region while enhanced mid-level westerly flow associated with it spreads from southern CA across the Southwest. Some modified moisture return is anticipated across south TX late Thursday night/early Friday morning, but this will remain well downstream of the shortwave trough. As such, the lack of moisture/buoyancy ahead of this shortwave will preclude thunderstorm development. ..Mosier.. 12/11/2024
