A frontal boundary is sagging south into the Region before it stalls and then heads north tonight. In our warm and humid atmosphere, we’ve sparked isolated showers and downpours. As of 6pm the heaviest downpour will roll through South Haven and eventually Valparaiso with lighter showers stretched out into portions of LaPorte County. We could see an additional pop-up or two before the evening is out, but the majority of these are tied to daytime heating along this weak front.
