April 9th, 2013 Forecast

A frontal boundary tries to slide down into our area but struggles to make much progress over the next 60 hours, resulting in a rather mild stretch of weather ahead.  With the frontal boundary trying to slide down, a disturbance pushes east along the front and results in some showers, perhaps a rumble of thunder overnight.  The best chances (er, only chances) of showers reside farther north and northwest of the city -- beyond Allentown and Reading.  Elsewhere, some fog or low clouds are possible overnight in a few spots as milder air pushes in off of the chillier Atlantic. Best chances of fog may end up residing down across South Jersey...we'll have to keep an eye on any fog bank development this evening in the Atlantic and see if it pushes on in.  Lows generally drop into the 50's.

Tuesday is shaping up as a warm day -- any morning fog will burn off, leaving a mix of clouds and sun through the region. Some spots could hit 80 -- best chance of this is along I-95 and points southwest -- Chester County down into Delaware. Most of the rest of us nudge the upper 70's but don't quite get to the 80 degree mark.  The Shore moderates to near 70 as fog holds there longest.

The forecast is a bit more fluid on Thursday as we keep an eye on the prospect of a backdoor front looming nearby.  Some guidance has this front sliding through, others keep the front north of us.  Thursday's forecast could end up bouncing around a bit before we get there...warmer guidance keeps us around 80 while the modeling that shows the front sliding through shows us dropping back in the afternoon.  I dropped the high for Thursday to reflect the possibility of the backdoor front crossing through after a mild start but again, this forecast could change.  Rain and thunder on Friday will not...nor will the nice weekend ahead!
