Chris Michaels at WRAL does a great job explaining things and keeping it real:  
	 
 
	
		SUNDAY UPDATE
	
	
		I'm not showing exact numbers this morning, but I imagine we'll put out a "first-call" map this afternoon for what's to come Tuesday evening-early Wednesday.
	
	
		Let me explain why.
	
	
		- I don't believe in jerking you guys around with a change in the forecast every 6-12 hours. We've been consistent in saying the coast gets the most out of this.
	
	
		- For instance, a shift of 25-50 miles changes everything you see Tuesday evening/early Wednesday. Saturday morning, Raleigh's odds of 1" of snow were 55%. Sunday morning, they're 29% because of a subtle shift east in the modeling.
	
	
		- The best chance of 1" of snow or more is near/east of I-95.
	
	
		- Weather balloon data will begin showing up in the models we get between 11a and 1p today. That should give us some clarity.
	
	
		- By Sunday afternoon, you'll have 48+ hours of lead time. That's more than enough. Being first is cool, but putting together as accurate and clear a forecast as possible takes priority.
