Dense fog has already developed and will likely lead to widespread freezing fog on Tuesday morning. This will cause bridges and overpasses to be slick in many spots and especially where temperatures are lower than 32º.
Temperatures should be near freezing area-wide with the best chance for below freezing temperatures in NW Arkansas but a few slick spots will also exsist into the Greater Fort Smith area as well.
This will create patches of black ice on bridges and overpasses; especially high elevation bridges and overpasses on I49 from 3am to 9am Tuesday.
After sunrise on Tuesday any black ice will quickly melt with temperatures warming into the 50s by the afternoon.
The Dense Fog Advisory is set to expire at 9am.
The next chance for road hazards will be on Thursday night as rain could briefly change to snow on the backside of the next rainy system.
