Temperatures should reach the 90°F mark Wednesday afternoon, and the thunderstorm chances increase later in the day with a pre-frontal trough in the vicinity. Given the amount of dry air aloft, thunderstorms will have a difficult time initiating until they are able to break through the dry air, and that isn’t expected to be until later in the day, mainly in the evening hours. There is some strong/severe potential, but very isolated, and we will monitor for the development of storms that carry damaging wind potential, small hail, frequent lightning and heavy downpours Wednesday evening. The actual cold front is expected arrive earlier in the day on Thursday, which would prevent any severe weather, but showers or a thunderstorm could occur before 2pm until the front sinks further to the SE. Skies then could actually begin to brighten toward Thursday evening, and then a couple of temperate and lower humidity days will return for Friday and Saturday. An area of low pressure moving from the Ohio Valley looks to affect the area later on Sunday with showers and thunderstorms, followed by another system moving through the Great Lakes on Monday that will drag a strong cold front through the area later on Monday. This front will usher in cooler temps that will back to the upper 70s on Tuesday for highs!
