Another mild and stormy week ahead

Another mild and stormy week ahead, After a burst of cool weather this weekend, another mild week is in store for the Ohio Valley. However, with the warmer weather comes the threat for more showers and thunderstorms. Severe weather will even be a threat once again at times this week.

Expect dry weather for the majority of your Monday. Skies will start out somewhat overcast but turn mostly sunny by the afternoon. A cold front will slowly sag southeast towards the region during the evening hours on Monday.

Thunderstorms will fire along this front across Indiana and northwestern Ohio. These storms will push east into central Ohio during the overnight hours and early Tuesday morning. Energy will build in the upper levels of the atmosphere Monday afternoon and provide fuel for the storms throughout the night.

This combined with a low freezing level (around 10,000 feet) will promote hail inside the thunderstorms. Sufficient wind shear will be in place to sustain significant updrafts in thunderstorms so isolated severe weather in the form of large hail will be possible Monday night and early Tuesday in the strongest storms.

Scattered thunderstorms will be ongoing at the start of the day Tuesday and the frontal boundary responsible for the rain will hang up around central Ohio.

This means that at least scattered thunderstorm activity will remain possible throughout the rest of the day. Highs will be dependent on exactly how widespread any rain is, but temperatures should be able to reach the 70 degree mark.

With the front staying around the I-70 corridor Tuesday night and Wednesday, scattered showers and thunderstorms will remain in the forecast. Wednesday will feature slightly warmer temperatures with highs reaching the middle 70s.

Thursday will be the warmest day of the week as the front surges northward ahead of a developing area of low pressure across the Midwest. Expect plenty of sunshine and highs in the lower 80s along with a strong southwest breeze.

The area of low pressure in the Midwest will move northeast and swing a cold front through on Thursday night. With such a strong cold front moving in, strong thunderstorms will certainly be a possibility.

Plenty of instability will build up in the atmosphere on Thursday afternoon but it will slowly wane as temperatures cool off Thursday evening.

The exact timing of the front will determine the risk (if any) for severe weather. Damaging wind, hail, and heavy rain would be the main threats in any stronger thunderstorms.

Some rain may linger into early Friday morning. Skies will remain mostly cloudy through the majority of the day and the temperature will cool off into the 50s by the afternoon hours. Highs will once again drop into the 50s for Saturday just like this past weekend. The early call right now is for dry weather both next Saturday and Sunday.
