952 ACUS03 KWNS 020553 SWODY3 SPC AC 020551 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1251 AM CDT Fri Oct 02 2026 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast for Sunday. ...Synopsis... A large-scale upper trough will continue to deepen Sunday as the parent low moves out of Ontario and into western Quebec. A leading shortwave trough will quickly move from the Great Lakes into the Northeast, with an attendant cold front. However, little if any instability will be present to support thunderstorms. Behind the leading wave, a secondary and stronger backside speed max will nose into the Upper Great Lakes late in the day, with another surface high building across much of the Midwest. Scattered thunderstorms will remain possible from the TX Coast to FL, where low-level moisture and instability (500-1000 J/kg MLCAPE) will exist. Weak shear and warm temperatures aloft will not favor severe storms. ..Jewell.. 10/02/2026 $$
