It's a bit chilly

It started with March and now April is becoming a bit bipolar. Below is the forecast discussion for Union, NJ:

There’s a possibility for rain/snow showers this evening due to a deep trough created by a low pressure system currently over Eastern Canada. We can expect a low of around 33 degrees tonight. For Thursday, temperatures will rebound as we can expect a slight warm-up with temperatures in the lower 60s and mostly sunny skies. Temperatures will remain near the low 50s for the remainder of the week as we can expect a low pressure from the central plains to move in bring the possibly of some showers. For the weekend we can expect cooler temperatures as another unseasonably cool air mass settles in from Canada.

OK I know I’m a meteorology student but come on snow for tonight? Early today there were already a few reports of flurries and as I recall only a couple of days ago we had sunny skies and temperatures in the mid-50s. April is a month of extremes though. One day the temperature can be near 90 and the next there could be snow. Talk about indecisive!
