It's foggy out there early this morning. Visibility levels are under a mile for almost the entire Delaware Valley as you head out the door in the next hour or two. The good news is that the fog that's in place thanks to last night's rainfall will lift after 7 AM in quick fashion from west to east. A weak front is pushing through the region this morning and should help nudge up the breeze factor and help mix the atmosphere enough to help break the fog up. Clouds should lift later this morning, with a good deal of sunshine expected for this afternoon.
Temperatures will top out in the lower or middle 50's this afternoon just about everywhere, jumping about 10 degrees from this morning's lower and middle 40's start. Despite the mild temperatures, a bit of chill will kick up with northwest breezes at 12 to 18 miles per hour. At least the sunshine will compensate for the wind, somewhat.
Regarding Sunday, computer modeling consensus has continued to nudge Sunday's potential snow storm to the south again last night. Philly is on the very northern fringes of snow from this system, with areas to the north likely to not see much of anything at all from it. South of the city stands the best chance of accumulations at this point and some spots in Delaware and Maryland could pick up a few to perhaps several inches of accumulation. Odds don't favor those higher totals, as of now, here in Philly. I will have a full discussion on the snowy potential this evening, including a forecast accumulation map for Sunday afternoon and evening.
