The next storm system is another "Alberta Clipper" coming out of the Northwest. It will increase our clouds tonight and spread a bit of light snow into the area by tomorrow morning. Temperatures overnight will be mild due to the cloud cover across southeast Wisconsin. Look for patchy light snow on and off tonight, Thursday and through Friday with very light accumulation. As that low pressure pulls away, the jet stream digs a deep trough into the Great Lakes region ushering in much colder readings for Friday and Saturday. High temperatures on Saturday stay in the teens, but start to warm again on Sunday.
