Technical Forecast Discussion
Short-Term Forecast (Sunday 09/07/2025 through Tuesday 09/09/2025)
An upper-level trough is expected to push out of the region overnight, leaving the region with primarily zonal flow aloft. 500 mb height tendency will remain fairly neutral or positive, indicating a stable atmosphere to persist into the early work week. Temperatures throughout the surface and mid-levels will remain relatively cool, though will begin to trend warmer as we near the end of Tuesday. The deep trough that has allowed cooler air to flow down into Ohio will be completely dissolved by Tuesday, creating the space for ridges to form out from the zonal flow that will sit over us on Monday. An incredibly dry airmass will dominate the short-term, allowing skies to remain clear during this time. Surface high-pressure will remain over much of the eastern United States, keeping conditions stable. Overall, minimal change from today through Tuesday is expected to occur with plenty of discouragement for vertical development.
Long-Term Forecast (Wednesday 09/10/2025 through Saturday 09/13/2025)
Much of the same can be said about the long-term. High-pressure will only continue into the remainder of the week. An upper-level ridge with an incredibly weak gradient will slowly build during this time and barely crawl its way eastward. However, despite this ridge not residing over Ohio, it will still let warm air to flow into the region, allowing a warming trend to return, pushing us back into the upper-80s by the end of the week. Upper-air temperatures will slowly warm back up as well as we near the long-term, bringing back the stacked, hot air we experienced plenty of times prior. By Thursday and especially into Saturday and Sunday, the 850 mb temperature anomaly will slam into Ohio quite hard as another indication of the heat returning once more. Very little will change into this next week and much of the same sunny weather should be expected during this time.
