SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1159 PM CST Thu Dec 11 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated weak thunderstorm activity is possible across South Florida and the Keys Saturday afternoon into Saturday night. ...Synopsis... The large-scale pattern on Saturday will feature a ridge across the western CONUS with troughing across the east. This mid-level trough will amplify on Saturday as a strong mid-level jet streak moves from the northern Plains to the Midwest. At the surface, a cold front will sharpen from the Ohio Valley to the Plains and move south rapidly Saturday evening. ...South Florida... Tropical moisture will start to advect northward across the southern Florida Peninsula on Friday. If this advects far enough north during the day, a few thunderstorms may be possible on the eastern sea breeze. During the overnight period, storm chances will increase across the western Florida Peninsula as a mid-level shortwave trough traverses the Gulf. Limited instability should preclude any severe weather threat from this activity. Shallow convection may develop along the southward moving cold front from southeast Texas to central Alabama late Saturday night, but warm temperatures aloft should limit lightning potential. ..Bentley.. 12/12/2025
