SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1109 AM CST Fri Dec 12 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated weak thunderstorm activity is possible across portions of the Texas and Louisiana coasts, as well as South Florida and the Keys Saturday afternoon into Saturday night. ...Gulf Coast... An upper trough will deepen over the eastern half of the CONUS on Saturday, though stronger west/northwesterly flow will be displaced well to the north of the region. At the surface, strong high pressure will build over the Plains into the Midwest, shunting a weak cold front south across the western and central Gulf Coast vicinity during the overnight hours. Modest moisture will be in place along the TX coast into the central Gulf coast vicinity, with richer tropical moisture across South FL and the Keys. This will allow for modest destabilization ahead of the boundary. Weak forcing for ascent, warm midlevel temperatures, and weak instability will preclude strong updrafts. Nevertheless, isolated thunderstorm activity will be possible near the TX coast into southwest LA, as well as South FL and the Keys. ..Leitman.. 12/12/2025
