Coastal Storm Threat Is End-of-Week Wildcard

By Matt Rogers

Main threat delayed to late Thursday and Friday

* Full Forecast | Later: What's Causing Snow to Decline? *

Next Chance of Accumulating Snow: Thursday-Friday
Probability of Accumulating Snow: 30%
Most Likely Potential Impact:

We still have an interesting situation on our hands. After seeing exceptional warmth tomorrow (60s!), the computer weather models want to send cold air back down into the D.C. area just ahead of a possible second storm system that rides up along the East Coast late Thursday into Friday.

Keep reading for a summary of the possible storm scenarios...

Several scenarios remain possible, including the storm tracking far enough inland to tap mild air from the ocean resulting in more rain than snow or, less likely, heading farther enough out to sea to mostly avoid our area. Snow lovers should hope for a track in the middle of these two possibilities -- but even then the cold air will be in limited supply.

Needless to say, a whole lot needs to be resolved. Since the timing has been pushed back to late Thursday and Friday, it gives us more time to get a better handle on this potential snow accumulation threat. Unfortunately, there are more questions than answers right now, so please check back for frequent updates in the next two days.

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

The 12z NAM shifts a little to the west, from Greensboro to Ocean City. Not good for snowlovers in the DC area.

The 60 hr. total qpf has my area in the bullseye for 6+" inches of qp. DC area is forecast to receive 3-4". This will likely not materialize, but would certainly put a big dent in the longstanding drought. Many streams and ponds are dry, which is very unusual for Dec.

Wintry precip. potential still exists for the BR and to the west, according to the latest NAM.

Most newer guidance continues to shift west with the low giving most of the region rain -- which shouldn't be terribly surprising I suppose.
