Promo: Probabilities, Forecast Certainty

There are frost and freeze warnings out for parts of the Southeast tonight. But what does that really mean?

Well, you can look at the zipcode forecasts on AccuWeather.com and see that we're predicting the temperature to drop below 32 in some of these locations.

But what if your business depended on knowing the real probability that the temperature would, or would not, drop below a specific threshold like 32 degrees? This is where a new product, ClearDecisions™, comes into play.

AccuWeather.com ClearDecisions gives you the probabilities of an event happening, from several different ensemble* computer models. From the map below (the GFS Ensemble model), you can see that the probability of the temperature being below 32 degrees tomorrow morning is almost 100% in most of Tennessee, but very unlikely in the southernmost Deep South.

If you have a specific location or set of locations you're concerned about, ClearDecisions can graph point probabilities for you, or export statistical information to Microsoft Excel. If you are interested in a trial of this business service, click here.

*Ensemble computer models are run many times from a slightly different set of weather conditions. The resulting statistics can then be analyzed to determine probabilities and forecast certainty.
