Shot Of Polar Air To Bring Frost, Possible Snow To Some Over Weekend

PITTSBURGH (KDKA) -- A shot of cold air is expected to plunge into the state on Saturday morning making this weekend feel more like the weather you'd expect to see on an early April day.

In fact, the highs expected in the mid 50s and lows in the mid 30s is close to the 30 year averages for April 1st.

So why are we going to see it? A potent chunk of polar energy will dive south behind an early Saturday morning cold front.

This along with a long track of winds coming in from the northwest will keep cold air in place over the weekend. Technically speaking the weather will be cold enough in the upper levels all day on Sunday to support snow.

The question is how cold does the surface included elevated areas get and if that cold lines up with moisture moving in.

For Pittsburgh it's been 50 years (1966) since the city has seen any snow whatsoever in May.

It's doubtful the city will see any snow. It's a different story for elevated areas where there will be at least a small chance for snow on Sunday morning. At this point any snow that falls would be more of a novelty and won't have any real impact on drivers or area roadways.

At this point the bigger concern looks to be on Sunday and Monday morning with temperatures cold enough to support frost.

In fact we may set a record for the cold on Sunday morning with the current record low being 35 degrees. My forecast calls for a Sunday morning low of 37 with a low of 35 on Monday. The Monday record low is 32 degrees.

With the cold getting the big headlines heading into the weekend it may be easy to forget about rain chances.

We expect widespread rain from 6 a.m. Saturday morning through Noon. Spotty showers are also expected to continue for the rest of the day into the overnight hours. While small, we cannot rule out the chance for a passing Sunday rain shower.
