Convective Outlook
— Day 3
No Severe Thunderstorms Forecast
Summary
The potential for organized severe storms continues to appear low on Wednesday.
Synopsis and Discussion
An expansive ridge will be present across the CONUS on Wednesday. Upper-level troughs will be present near the Northwest coast and in the Northeast, however. A few stronger storms will be possible within western and central Montana, though repeated convection on previous days will likely lead to cooler temperatures and uncertain storm intensity. While there still is some uncertainty to the track of the upper trough off the Northwest coast, some potential exists for gusty outflow wind in central/eastern Oregon. Across parts of the Mid-Atlantic, a moist and unstable airmass will be present south of a surface boundary. Subtle mid-level height falls may be enough to initiate isolated thunderstorms. However, there is also potential for the environment to stay capped. The environment would support damaging winds if storms can form.
