Most Unpredictable/Unstable Weather in the U.S (climate, tornado, snowfall)

Very interesting study here. An evaluation on how unpredictable the weather is, not if the weather is good or bad.

Lots of work went into this.

The statistics we’ll be evaluating fall into three major categories.






First, temperature:

• High temperatures;
• Low temperatures;
• Daily mean temperatures.

Second, precipitation:

• Rainfall, in inches;
• Snowfall, in inches of snow (rather than the liquid equivalent);
• A binary variable indicating the presence or absence of precipitation (without regard to the type or amount of it). If there’s any precipitation at all over the 24-hour day, we score this variable as one. Otherwise, it’s zero.

Finally, severe weather and the conditions that contribute to it:

• Wind speed;
• Humidity;
• Cloud cover;
• A binary variable indicating whether there was a severe weather event (a thunderstorm, tornado or hail) in the city that day.

Looks like we're as unpredictable here as Southern Michigan & Southern Mississippi.
Western U.S & Florida more predictable than not.

Northern Plains unpredictable

New England more on the unpredictable side which I know from experience.

The only reason parts of the southeast are somewhat predictable is because of summer. I'd like to see the whole of the US for just say January. Coastal GA in January would be just as unpredictable or maybe even moreso than here.

A very similar thread exists from 6 months ago:

But yes, it's an interesting topic.

As expect, the midwest has the most indeterminable and capricious weather.

Very intersing thread indeed. Seems that continental climate =unpredictability. Is there something like that available for other continents as well?
