Forecast changes a little bit almost every hour. Blink and it'll be different.
At 5:00 pm today on weather.com, forecast is high 28, low 18 with 1 inch of snow. It says "Snow during the morning will taper off as a few snow showers during the afternoon. Much colder. High 28F. Winds NNE at 10 to 15 mph. Chance of snow 80%. About one inch of snow expected.."
The low is a bit higher, it's a bit windier, and the chance for snow went up by 20% than the forecast showed 3 hours ago.
I guess we really won't know what the weather will be till Sunday at 3:00 pm!!
