Warm weather is expected on Tuesday and Wednesday with additional shower and storm chances possible.

Discussion

KEY MESSAGE 1. A warm front will lift north across the area tonight and allow for warm and humid conditions to return for the weekend. For Saturday, a mid-level shortwave will move through the Ohio Valley and allow for shower and thunderstorm development. With a conditionally unstable air mass, it is possible for a storm to become stronger with gusty winds, hail, and heavy rain during the peak heating hours on Saturday afternoon and evening. For Sunday, there is growing consensus on a cold front approaching and slowly moving south across the forecast area. This front should provide lift to generate at least some convective activity on Sunday. However, the air mass should be less suitable after Saturday's activity and shower/storm coverage should be lower.

KEY MESSAGE 2. The forecast for Tuesday and Wednesday is trending more unsettled as the forecast area will be in the middle ground of a ridge to the south and a trough moving through Canada. The ridge should help keep the area dry on Monday with high pressure moving through the region. However, the ridge will back off a bit for Tuesday and Wednesday, allowing for some of the energy of the upper trough to enter the Great Lakes, coincident with a cold front moving through the region. The air mass ahead of this system will be warm and humid and again conditionally unstable to allow for scattered shower and storm activity next week. Will need to watch this portion of the forecast for trends as it approaches closer.
