Snowy Late Thursday Into Friday, But How Much?




There will be snow on Friday and there is no debate about it.

The question at this point is will it be an average of 1-3 inches of snow throughout New Jersey or will there be snowfall in excess of 4 inches.

The North American Model has been bouncing the snow totals around. One model run will have the low stronger and closer to the coast and then the next run will show a weaker, further offshore storm. For instance, today at 06Z it shows a fairly substantial snowfall and the new 12Z run shows a light accumulation of snow.

The GFS model at 6Z shows about 3-6 inches, maybe a bit more, for Central and Southern New Jersey. The GFS model in from 12Z shows generally 1-3 inches for Central New Jersey and 3-6 inches in Southern New Jersey.

Later today or tonight, with the extended forecast, I hope to throw out preliminary snowfall total maps. These can be fine tuned as we approach Thursday Night into Friday.
