A cold front slowing moving to the south and east across the northeastern US will not only be responsible for a pleasant air mass behind it, but also some strong to severe storms ahead of it. That severe weather risk will span from northern New England through the Ohio River Valley. Damaging winds and small hail will be the main threats associated with these storms, as well as heavy rain. Any heavier downpours may produce localized flooding in some areas that deal with these storms.

The radar is rather quiet this morning with just a few spotty showers over the Ohio River Valley. That activity will then ramp up during the latter half of the day as multiple lines of hit or miss thunderstorms develop ahead of the front. There will be some clusters that form over the interior Northeast that will feature a more widespread rain, and its these clusters that feature the greatest concern for strong storms and flooding.

Now while many of these storms dissipate in the evening over the Ohio River Valley as the best atmospheric dynamics shift to the east, a line of heavy rain and thunderstorms will take over the Northeast overnight. These storms will span from northwestern New England down toward the central Appalachians Mountains and the inland Mid-Atlantic region. A few of these storms may be severe, but the best risk for any severe storms will be during the daylight hours thanks to the added instability. This instability promotes the growth of the thunderstorms, an important ingredient for intense storms.

There will be a couple other areas to watch for severe storms on Friday. That includes southern Louisiana and the surrounding areas as a few hit or miss thunderstorms slide to the west associated with an upper-levels disturbance tracking along the Gulf Coast. Severe storms will also be a possibility along the leeward side of the Rocky Mountains in Wyoming and Colorado. Scattered thunderstorms will develop in the afternoon, becoming most widespread in eastern Colorado. An isolated tornado cannot be ruled out in a region that sometimes experiences surprise tornadoes.

Looking ahead to Friday, the cold front will continue to track toward the East Coast over the Northeast. That will trigger a few strong to severe storms primarily across New England. Damaging winds will remaining the most significant threat posed by these storms. A limiting factor will be when the storms form, which will likely be in the early morning. Nonetheless, heavy, gusty storms will move through inland New England Friday morning, then across coastal areas midday. Storms will linger around Cape Cod before clearing out in the evening, which will give way to a fantastic weekend. A few showers and storms in the hit or miss variety can also be expected across the Mid-Atlantic, especially near the coast during the day Friday.
