 However, a storm in the nation's center means that some thunderstorms can be expected within a swath from Missouri and Illinois into western parts of lower Michigan through the day as more comfortable and less humid conditions greet areas from the Ohio Valley into the interior mid-Atlantic with a reprieve from unpleasant conditions and a mainly dry day today. For Syracuse, look for changeable skies and cooler but humid conditions with a passing shower and a high of 78. I'm AccuWeather.com meteorologist LaTroy Thornton.
