I’ve noticed lots of people asking “how likely” snow is with the developing winter storm in the East. This is a map of *probabilities* of snow amounts.

Probability of 1″ or more now until 6am Central time Wednesday |

Because snow is infrequent in Arkansas, Mississippi and Tennessee one inch can cause major problems which is why I am posting the probabilities of that amount. The dark orange dot on the Tennessee-Mississippi border = 90%. In Memphis, the probability of 1″ or more is 50%.

Probability of 2″ or more between 7am Eastern Wednesday to 7am Thursday |

Above is the probability of two inches or more. The deep red in West Virginia is 95%.

Finally, the probability of six inches or more:

Probability of 6″ or more. The pink areas = 80%. |

Here are some probabilities for specific cities: D.C. 40%, Baltimore 55%, Philadelphia 55%, NYC 60%, Providence 70%, Boston 60%.

I’d be interested in any blog reader comments as to whether they believe this is useful (i.e. specifying the probability).

Finally, there is a chance of tornadoes in the Florida Peninsula today.

well it would be better, if some of the things that were said, told me about what I am to expect, I live in Milford NJ 08848 and really cant be sure what to expect here

Hi Vivian,

Thanks for the comment. There is a 55-60% chance of 4" or more (see above map). The most likely amount is in the 6 to 9" range (see map with posting below).
