The last few mornings here in Los Angeles have had a marine layer, with low clouds and haze which dissolve by mid-morning into bright sunshine. Well the same has been happening in Iowa as well, with a lot of dense fog shrouding the sky. Dense Fog Advisories continue through mid-morning for the eastern half of the state, mainly east of Interstate 35. Another round of dense fog will be possible tonight into tomorrow morning before some rain moves in late Friday evening into the weekend.
