Technical Forecast Discussion
Key Messages:
- Temperatures will continue to drop into Saturday, dipping into the lower-to-mid-50s as cold air is advected from Canada into Ohio, though they are expected to rise by Sunday.
- Rain chances may return on Friday, but we have a greater chance for showers and maybe a rumble of thunder early next week.
Short-Term Forecast (Thursday 04/30/2026 through Saturday 05/02/2026):
Relatively stable air will move through Thursday as weak high-pressure fills in behind Wednesday’s low. Clouds will remain but are expected to decrease into Thursday evening. A trough aloft will allow cold air to advect into the region and continue dropping temperatures by the end of this week and into the weekend. We may see temperatures steady themselves in the mid-50s Thursday and Friday and possibly the lower-50s by Sunday. A very weak low may move through on Friday, allowing clouds to return by then, as well as the chance for some rain showers by midday as moisture pushes through. Instability remains quite low, leading to low chances for storm development. Winds will be breezy into the weekend, though they’re expected to remain consistently breezy during this time.
Long-Term Forecast (Sunday 05/03/2026 through Wednesday 05/06/2026):
Temperatures will steadily begin to rise as high-pressure slowly fills the region once more. Multiple upper-level troughs will develop near Ohio, forcing the cooler air to shift northward and allowing temperatures to steadily rise by Sunday. The next chance for showers and thunderstorms may arrive by Monday as a minor low cuts across over Ohio, bringing moisture and some instability into the region. While severe storms are not expected at the moment, a rumble of thunder may occur during this time. Temperatures will rise into the upper-60s to lower-70s by then as the chance for rain and maybe some minor storms persist through Wednesday. Though, these storm chances are not expected to be particularly strong.
