Sunny Start, Soaking Finish Tonight

Rains on the way tonight -- at least an inch of rain can be expected for many locations as a southern soaker comes barreling through the Mid Atlantic and Northeast.  Rains are, as of early this morning, extending from Southern Indiana down into Southwestern Virginia, with the center of low pressure in Alabama.  This system will move northeast through the day today and its shield of clouds will move overhead towards midday, with rain moving towards the Philadelphia area later this afternoon.

Rain should move into the city after 4 or 5 PM, steady to heavy later tonight before tapering off towards the morning commute.   It may start as a period of sleet or snow in the Poconos this evening before temperatures aloft and in the lower atmosphere moderate just enough to allow transition to rain for them.  Winter weather advisories are out for Carbon and Monroe Counties to our north for this evening with the storm system bringing an inch or so of slushy accumulation before that changeover takes place.

Temperatures are starting in the 20's for the vast majority of the surrounding area, with the city clinging to low 30's this morning under clear skies to start.  We should reach a high of 48 this afternoon under increasing clouds, with the vast majority of the daylight hours dry and fair.  East breezes will increase towards dinner to around 10-15 mph, increasing more tonight (12-20 mph in the city, 15-25 at the Shore plus higher gusts).   In a nutshell, today starts chilled but decent and descends into a rainy night as the southern storm moves on in later on.
