Storm Prediction Center Outlook October 15, 2021
A sharp cold front with pockets of Heavy Rain and a few Severe T-Storms, will push through the Ohio Valley on Friday, leaving a chilly and breezy fall-like weekend in its wake...
Hurricane Pamela, which came ashore in western Mexico yesterday, will merge with an advancing cold front starting tonight through Saturday morning across the Mississippi Valley, Midwest, Ohio Valley, and northern Lakes. This will lead to a noticeable cool down for the weekend as we continue to head into a more typical autumn pattern.

The remnant tropical low currently advancing through Texas, will trek towards the western Ohio Valley later tonight and tomorrow. Behind the front, chilly and rainy conditions will prevail. To the right of the low, cyclonic flow will be enhanced. With warm, moist air flowing in from the Gulf conditions will be set for the potential of rotating thunderstorms through 9pm Friday.

ECMWF/Pivotal Weather 500mb Height/Wind Speed for October 15, 2021
A roaring jet stream, likely over 120 knots at around 18,000 feet from the west and southwest, combined with southerly and southeasterly surface winds at the surface will allow shear profiles to be modest, thus an elevated tornado threat for the majority of the Ohio Valley Friday afternoon into evening. These storms will likely be rapid movers, so a quick spin up tornado or two and severe wind up to 70mph could strike with little to no advanced warning, so stay vigilant if a storm approaches your area.

The cold front should move through the Ohio Valley during the late evening hours of Friday, ending the severe threat and ushering in much cooler air for Saturday and Sunday.  

Stay tuned for the latest concerning this severe weather threat for Friday.
