Why is nature playing april fools?

Nature is playing April fools by it is making us think that it is going to be warm but there is a cold front coming in and its going to snow. Its kind of fooling us with making us think its going to be warm when really by the end of the day its going to be cold and snowy. The cold is coming in because of the cold front from the northwest winds. The La Nina conditions have a part in this by it having cold ocean temps. that come in to the coast causing snow and other cold conditions. the ploar circulation circulates the air. The North Amerian Jet Stream causes the cold weather by bringing in the cold with the jet stream. The stream is strong causing it to pull in cold weather.
