PHILADELPHIA (CBS) – A mid-February chance of snow for the Delaware Valley from a fast moving low pressure system to our south.

What it means for us on pre-Valentine’s Day consists of a chance of one to three inches of snow through the Philadelphia area.

It starts as rain Wednesday afternoon with temperatures in the 40′s. But as the low passes by, colder air gets drawn in. That begins the changeover to rain and wet snow around 7 p.m. with temperatures remaining above the freezing mark for most of the storm system.

After midnight, the precipitation should be all snow, though by this point, the snow is beginning to end from west to east.

Lows by morning reach 28 to 33 degrees, which means that some roads could begin to briefly freeze.

Thursday warms up to the mid to upper 40′s, perhaps fueled by Valentine love in the air.
