773 ACUS01 KWNS 101911 SWODY1 SPC AC 101910 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0110 PM CST Wed Dec 10 2025 Valid 102000Z - 111200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast through tonight. No changes. ..Hart.. 12/10/2025 .PREV DISCUSSION... /ISSUED 1021 AM CST Wed Dec 10 2025/ ...Synopsis and Discussion... A shortwave trough, and accompanying intense jet streak with 500 mb winds over 100 kt, will continue eastward through the OH Valley today and off the Northeast coast by early tomorrow. Surface low associated with this wave will progress northeastward from its current position over southeastern Lower MI/southwestern Ontario along the St. Lawrence Valley today, continuing through ME and into the Canadian Maritimes by early tomorrow. An extensive cold front extending southeastward from this low will push quickly eastward/southeastward through the southern Plains and much of the eastern CONUS, ending the period well off the East Coast. Passage of this cold front will reinforce the dry and stable conditions across the majority of the CONUS, precluding thunderstorms. Modest low-level moisture will remain over central/southern FL throughout the day, but warm low to mid-level temperatures will prohibit deep convection, limiting the thunderstorm potential. $$
