Fair weather will continue today under Canadian high pressure. The high will support a nearly cloud-free day with slightly below-normal daytime temperatures.
An initial push of showers late tonight with an advancing low pressure system should remain mainly in the far northern counties of Ohio. However, showers and thunderstorms will become more likely on Thursday afternoon as a cold front makes its way into east-central Ohio.
With the decent amount of instability and upper-level shear that’s expected, the environment will be able to support a few stronger storms capable of producing strong wind gusts. The Storm Prediction Center has our area highlighted for a Level 1, Marginal Risk for damaging wind gusts. The risk is conditional on whether sufficient daytime heating can occur ahead of the arrival of the cold front.
The cold front is expected to continue south, then stall in the vicinity of the Ohio River Valley and remain nearly stationary through Saturday. This will keep the daily threat of occasional showers and thunderstorms in our forecast through the end of the week.
HEAT AND HUMIDITY INCREASE NEXT WEEK
Model ensembles indicate that the stalled frontal boundary to our south may finally lift back north as a warm front on Sunday. An upper-level ridge of high pressure will build overhead in the wake of the warm front, setting up an influx of warm and humid southerly air.
The main influence of this pattern in our area will be increasingly hot and humid weather conditions to wrap up the month of June. Daytime temperatures in the 90s look increasingly likely with dew points hovering around 70°. Heat indices may settle into the 100° range on Monday and Tuesday.
Model ensembles also suggest this pattern could persist through much of next week. If that turns out to be the case, heat advisories will likely be issued.
