Forecast Discussion: PM2.5 readings are in the Moderate range yet decreasing as a cold front is passing quickly west to east through the Ohio Valley. High pressure will build into Michigan and Wisconsin Wednesday. A strong low pressure system will develop in the plains, yet moisture will be limited and little severe weather potential is expected ahead of the not-so-cold frontal passage Thursday night.
