The latest GEFS (Global Ensemble Forecast System) and Euro Ensembles are *currently* showing some robust numbers. Yes there are a few that are not as bullish and I am not discounting those, but whether you want “the big one” or just a few inches… pick your ensemble (image courtesy Weatherbell):
Next up the Euro Deterministic + Ensemble (courtesy Weatherbell):
Notice in the bottom graph that the *current* ensemble mean snowfall prediction for Reagan National Airport is 16″. If this were to verify on Saturday (remember these can change as more data comes in tomorrow) this would be DC’s largest snowstorm since February of 2010.
One of my goals on this site is to inform the public of potential significant weather. Bottom line is until I issue a final snow map, I am not making a call. What I am tired of if flipping on the news and hearing “we have the potential for a big storm” without discussing potential impacts in something that the public can quantify (ie: potential snowfall accumulations). Good Grief.
More updates to come tomorrow afternoon/evening after I look at the latest data.
