After an amazing string of 5 days at or above 70 degrees, we knew that things had to change. Fortunately although our temperatures will be dropping, they wont fall too much below our average of 62 degrees for this time of year. We will, however have some rain and thunderstorms to contend with as we transition to cooler air. A cold front associated with a storm system in Canada will push through our area tonight and could trigger some showers or a thunderstorm, likely very late. Storm chances increase tomorrow as the same cold front gets pushed back north as another storm system approaches from the Plains. Rain chances will build throughout the day and the Storm Prediction Center has placed the Stateline in a Marginal to Slight chance area for possible severe storms. The best chances for these storms will be in Iowa, but it is possible some of them move our way. The greatest threat from these storms will be hail and locally damaging winds, with a slight chance of a tornado. Keep tuned as we track these storms later tonight and tomorrow.
