Snow threat late Saturday night, a mix Sunday?

By Jason Samenow

* Turning cold: Full Forecast *

Next Chance of Accumulating Snow: Saturday-Saturday night
Probability of Accumulating Snow (1" or more): 40%
Most Likely Potential Impact:

The snow threat for the weekend remains, but a couple important changes have occurred since yesterday. The first is that the onset of any snow will likely be delayed until late Saturday night or early Sunday morning. The second is that there are increasing indicators that the snow may changeover to sleet and/or rain before ending, as milder air slowly works its way into the region on Sunday.

However, odds are decent (at least 50/50) we'll see some snow, and it's possible there could be a decent thump of two or more inches before any changeover.

Here is our current assessment of accumulation chances:

No snow: 35%
Dusting to coating (mainly on grass): 25%
1-3": 25%
3"+: 15%

Most likely scenario: A inch or two

As always, keep checking back for updates

The Snow Lover's Crystal Ball appears when the potential exists for accumulating snow beyond 24 to 36 hours.

Put me in the hoping for nothing camp. Taking my wife to Dulles early Sunday for her flight to Tuscon.

I'm not in the mood to fight icy roads yet again.

Latest GFS trended pretty warm though. Very unfortunate. However, we're still a few days out...

If you're a snow fan, you don't want to hear the forecast for next week.

I think Think Spring and I are going to have to keep our anti-snow juju going full steam this winter... :) I'm just thankful most everything finally melted today!

Come on Spring!

This one might be cooked. The trends lately are mostly bad for snowlovers.

"This one" being the weekend 1"-3"or the Blizzard of 2009 scheduled for Tuesday?

The article says "Most likely scenario: A inch or two" Yet directly above they put that probability at 25 percent. The probability of no accumulation is 35 percent. Why isn't no accumulation scenario "most likely". Is this wishful thinking by over zealous weather people?
