A snow storm that came through the area Saturday afternoon is causing some slick spots on area roadways.

Officials advise taking it slow on the roads because many icy spots have been reported.

Here's a look at what we're expecting:

Tonight: Snow at times; most places pick up an inch, a few spots can have 2". Low: 20

Sunday: Mostly cloudy, brisk and cold with a couple of flurries. High: 34 Low: 18

***Winter Weather Advisory for our southeastern counties from 7pm this evening until 1pm Sunday***

Snow started to spread into the area this afternoon as a clipper system moves in from the west. The snow will continue overnight before tapering off by daybreak on Sunday as the storm system quickly pulls away.  Around a coating to an inch or two (slightly more is possible for the higher elevations north and west of Allentown) of snow will be left behind from this system, so watch for some slick spots to develop.  A few flurries will continue to be possible at any times on Sunday, but the best chance for some flurries or even a heavier snow shower will come late in the day and at night as an upper level disturbance swings through the region. Otherwise, look for mostly cloudy skies on Sunday with highs reaching the low to mid 30s.  Another clipper system will move through the region late Monday into Tuesday bringing a bit more snow to the area.  Highs will hold in the lower 30s for the start of the work week.
