Technical Forecast Discussion
Key Messages:
- Stable conditions expected through Tuesday as high-pressure at the surface and zonal conditions aloft discourage significant vertical development.
- Severe thunderstorms may arrive Wednesday evening into Thursday morning as ample northwesterly moisture pushes through the region. Moderate instability with strong speed shear will allow for an organized squall line of thunderstorms to move through.
- Temperatures will quickly drop back down into the 40s and 50s by Thursday and into Saturday thanks to strong cold air advection aloft.
Short-Term Forecast (Sunday 03/08/2026 through Tuesday 03/10/2026):
High-pressure will continue into the coming days as zonal conditions develop over the Ohio Valley. Skies will continue to be clear into tonight and through most of the early work week. A warming trend is expected through Tuesday in-part due to the aforementioned high-pressure and the warm sector of an approaching low. These will allow for our temperatures to remain in the upper-60s to lower-70s a little while longer before quickly climbing back down to near normal temperatures. Clouds are then expected to develop moving into Tuesday afternoon as low-level moisture moves through with dry air aloft. Very stable conditions are expected during this time.
Long-Term Forecast (Wednesday 03/11/2026 through Saturday 03/14/2026):
By Wednesday, activity will begin to pick up as an intense mid-latitude cyclone moves through Wednesday into Thursday. A shortwave with an intense jet streak will crawl through the Midwest Wednesday and Thursday, situating Ohio in the right exit region of this jet streak. Low-level moisture will trail in from the northwest with significantly drier air aloft following alongside it. Instability will develop Wednesday as temperatures quickly cool with height during the day with surface temperatures in the mid-70s. Conditions are not expected to develop any supercells with strong speed shear and moderate instability. Severe thunderstorms will be likely Wednesday night into early Thursday morning with expected impacts still unclear, but a possibility for straight-line winds could be possible. By Thursday, the shortwave will weaken and continue moving eastward as high-pressure follows closely behind. The passage of the associated cold front alongside strong cold air advection near the surface, which will kick our temperatures back down into the 40s and 50s by the end of the week. Stable conditions will follow into Friday despite another low tracking just north of the state between then and Saturday. Slightly moist air will move eastward thanks to this low, but it will hardly be enough to produce anything more than cloudy conditions.
