Foggy Start, Some Sun Later

 After a not-so-foggy start to Monday, temperatures made a run at record levels in a few spots in the afternoon hours thanks to the near wall-to-wall sun.  Well, we're not going to have such wall-to-wall luck in the sun department today.  It's quite foggy out this morning around the region -- visibility levels down to a 1/4 mile or less in a number of spots and we have a Dense Fog Advisory until 10 AM for Southeast PA, South Jersey, and Delaware with the presence of low clouds and fog around.   Fog is also an issue where the advisory isn't out as of 5 AM and much of the region will have to deal with at least some fog this morning.

Fog should gradually lift -- likely after 9 AM -- the only question is who burns off first...the thinking is that we burn off first northwest and last at the Shore (in general) but this is not a lock by any stretch -- we could see holes developing in spots and spreading out from there based on sunshine doing its magic.

Unlike Saturday or Sunday, once we do burn off we won't completely sunny today.  There is a weak disturbance nearby that will throw some mid level clouds overhead, especially north of the city, so I do anticipate a sun/cloud mix.  A stray shower or thunderstorm can't be ruled out either in areas that get more sunshine than not today.

Temperatures, again, will be tricky to pin down (as they have been since Thursday) but the best chances of warmth reside along and west of I-95 where a high near 70 or just above it seems likely.  If we have more sunshine, we could slip into the lower 70's but the presence of additional fog and low clouds this morning may make a run into the upper 70's a bit tougher to pull off.  At the Shore, temperatures should get to around 60 this afternoon, with upper 60's common across South Jersey and Delaware.  Still a nice, mild day, but it probably ends up a few to several degrees less warm than yesterday.
