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.
