Technical Forecast Discussion
Key Messages:
- Stable air will dominate next week as surface high-pressure generally sits over the state even as we see a brief passing of a weak low just to our north.
- Frost is expected to be a concern tonight through Tuesday night into Wednesday morning as clear overnight skies allow rapid radiative cooling to at or near freezing.
Short-Term Forecast (Sunday 04/05/2026 through Tuesday 04/07/2026):
Significantly stable air will continue developing in the region tonight and tomorrow. While we will see a low sweep just to the north of us Monday, advecting colder air behind the surface cold front, this hardly will put a dent in the stability currently over the state. This low will hardly bring sufficient moisture to form a speck of clouds on Monday, so the start of this week is looking to be rain-free and sunny. However, these cooler temperatures we saw today will pose the risk for some frost overnight tonight through Tuesday night, especially as clouds rapidly clear overnight, allowing nocturnal cooling to occur. Through Tuesday, a large longwave trough will remain over the state, aiding in the further cooling in the region. Overall, nothing is anticipated as extremely stable air dominates through the end of the upcoming week.
Long-Term Forecast (Wednesday 04/08/2026 through Saturday 04/11/2026):
A warming trend is expected as we move into the latter half of the week. High-pressure will continue dominating Wednesday but will weaken slightly as a strong low in southern Canada brings strong southerly flow with warm air right behind it. Some clouds will form Thursday and Saturday, but weak precipitable water is expected over southeastern Ohio, limiting any rainfall that could occur. Generally zonal flow will dominate alongside the high-pressure at the surface, re-enforcing the strong stability we will see this week.
