Light snow and a mix may usher in New Year

By Matt Rogers

Disorganized storm keeps confidence low

* Wickedly windy and cold: Full Forecast *

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

A weak weather system is anticipated to move through the region Thursday before exploding into a major storm off the Northeast coast on Friday. The current thinking is the storm will intensify too late to bring heavy precipitation to the D.C. area, but we could see a period of light snow Thursday morning changing to a mix of sleet and rain during the afternoon and perhaps back to snow later Thursday night.

The first bout of snow Thursday morning may bring a dusting to an inch or so, and assuming the rain/sleet changes back to snow late Thursday night, another inch or so is possible by Friday.

Here are total accumulation odds (from both possible periods of snow):

Less than 1": 60%
1-3": 25%
3"+: 15%

Confidence is still very low so stay tuned for additional updates.

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

Wow, a crystal ball with no comments after 2 hours and 45 minutes. Wild, even on a holiday week. I'm happy for some light accumulation this weekend, as long as we don't get dumped on again... took a few days for the ol' back to return to normal, even with an 'ergonomic' shovel. I guess a foot and a half of snow is still a foot and a half of snow, no matter what kind of shovel you have. ;-)

Well it's 24.5F with pretty fluffy clouds passing by... hoping for a passing flurry to entertain the preschooler today. Stay warm, all.

Yes, a possible light coating is all relative now that we had our big December storm. Based on the current pattern type, it appears that we will have more snow opportunities (is that the right word?) over the next few weeks as well.

Totally agree, Matt. This one will get it together too far north, but the overall pattern is favorable for more chances in the coming weeks. We could maybe squeeze out an inch or two from this one if the upper low pivots through, but that's about it.

Hi guys - Do you think that it will get together enough to impact Connecticut/Southern New England? I'm headed up there to visit some family and wouldn't mind seeing some of the white stuff since I missed the big one here!

After last week's storm this one is a good reminder that a decent large scale pattern does not always bring good things for snowlovers. The devil is in the details...
