Shower Threat For Friday & Friday Night

Friday's rain system shouldn't be a big deal -- likely to produce a tenth to two tenths of an inch type rainfall amounts as showery rain spreads through the region in a couple of shots -- the first, generally north and northwest of the city in the morning, with the second following in the evening.

While this system will be rain for Philly, the potential for an early arrival across the Poconos with wave one of those showers could result in some freezing rain on the very front end early Friday AM north of Blue Mountain, especially towards Scranton and farther north (see the NAM below).  This shouldn't be an issue for us in Philadelphia from a shower or rain perspective -- anything that falls generally resides north of town.

Wave two comes through Friday evening -- mild and with rain for all.  Nothing significant to worry about around here.  A few hundredths to a couple of tenths of an inch are possible...again, nothing significant to worry about.

A larger storm system in the Midwest (modeled on the GFS above) will track through Minnesota and help push a warm surge of air into our world for the weekend, with 60 or warmer in the offing for the region this weekend.
