The trade off for mild temperatures this time of year, is more moisture. The result after these longer nights, are large areas of thick fog.
A Dense Fog Advisory is in place for much of the region, with many areas in central Maryland and across the Bay on Delmarva with near Zero visibility. It is so thick in some places, it’s more like a heavy mist and you will need your windshield wipers.
This will slowly burn off, and bring yet another warm afternoon.
Here is first look weather forecast, and NEW GFS Interactive simulation slider. Also see the journal of Maryland Weather conditions observed in Baltimore yesterday, climate report today, sunrise/sunset, moon phase, and daily weather map.
Dense Fog Advisory
The Dense Fog Advisory includes all of Maryland between Frederick and Ocean City. The fog is most thick across the Bay and Delmarva.
There is fog as well in southern PA, even though those counties are not included here. See the visibility report below.
The thicker fog is where the numbers are in red and purple. Many areas under 1 mile!
A very mild start to the day!
