403 ACUS01 KWNS 100556 SWODY1 SPC AC 100554 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1154 PM CST Tue Dec 09 2025 Valid 101200Z - 111200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms appears low today. ...Synopsis... The large-scale pattern will feature a ridge across the western CONUS with a trough across the east. A surface low will deepen below 990mb as it moves from the southern Great Lakes to the Northeast during the period. A cold front will extend southwest from this surface low and bring a reinforcing cold/dry airmass to much of the central and eastern CONUS. Significant moisture (60F dewpoints) will be relegated to far south Florida. However, even here, northerly flow should persist within the post frontal airmass. This should keep any thunderstorm potential well offshore. A brief period of southerly return flow across the western Gulf may bring some near 60F dewpoints to the Texas coast, but this should be short-lived as a reinforcing cold front moves offshore this evening. Thunderstorms are not expected across the CONUS today. ..Bentley/Thornton.. 12/10/2025 $$
