This sounds like a nightmare scenario and actually a bit specific. You okay over there? lol
This is exactly what it is and the guidance is getting full support on ensembles too. In fact, it may even trend colder if the synoptic setup stays the way it is. Good for winter weather, but someone in this sub, the warm nose will lurk and ice will be pure hell. I love your hood for a prolonged winter event. Going to look like deep winter by Friday
