NOAA surface loop forecast shows low pressure moving into the Midwest by this weekend.

A low pressure system spinning into the West today will track toward the Midwest by Saturday. The low will track through Iowa and Missouri, but it appears it may slide close enough to sideswipe Minnesota and send a wave or two of rain our way Saturday.

The latest model trends indicate a band of rainfall sweeping north out of Iowa Friday evening into southern Minnesota.
