SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1118 AM CST Sat Nov 15 2025 Valid 161200Z - 171200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible from the Lower Colorado River Valley into the Four Corners states on Sunday. Additional isolated thunderstorms may approach the central California coast early Monday morning. Severe storms are not expected. ...Discussion... A strong surface low off the Maine coast will continue to move east through the period on Sunday. A cold front extending southwestward from this surface low will bring a cool/dry airmass in its wake across much of the eastern CONUS. A warm/moist airmass should remain south of this cold front from the southern Plains and across the Southeast. However, shortwave ridging aloft should suppress any convective chances. Farther west, thunderstorms are expected from a series of mid-level shortwave troughs as they traverse the broader troughing across the western CONUS. This may result in isolated to scattered thunderstorms across the Four Corners region and into the central Rockies and also along the central California coast. Weak instability should limit any severe weather threat on Sunday. ..Bentley.. 11/15/2025
