Weather/Climate Anomaly in Pana, Illinois

This Wikipedia article has this to say about the central Illinois town of Pana:

There is absolutely nothing unique about the topography of Pana (that I’m aware of) that makes it any different from any other locality in central Illinois. The land is flat as a pancake for at least 45 miles in each direction. Hail in central Illinois is not an everyday occurrence, but it’s hardly unheard-of. AFAIK, there has never been a major greenhouse industry in central Illinois outside of Pana.

Anyone have any further information as to what this is about?

Wiki vandalism?

Well, there definitely was a thriving greenhouse industry in and around Pana at one time; remnants of it still remain. And the bit about “City of Roses” is (or was) true as well. So all I’m really stuck on is the supposed geographical/weather anomaly.

Sorry, misread your original post (overlooked the “outside” qualifier) and thought someone was having some fun. :smack:

The climate “anomaly” may actually be “luck”.

Is it an anomaly or luck or nothing at all? While I had heard that in Colorado at least Denver area hailstorms are frequent I had not heard this about Illinois. taking a quick look on the web, I find very little (nothing acttually) saying Illinois is known for hailstorms (a quick look - a couple different sets of search terms lokked at maybe 40 results).

I didfind a report from 1960 in which I found the following:

“All hailstorms were analyzed in which four or more U. S. Weather Bureau stations in Illinois reported hail. A total of 113 hailstorms days during the 50-year period met this minimum requirement”

So that’'s what 2.2 a year? Hell, get that many in Jersey (not every year)

I don’t know how geography could influence hail. Hail is produced when water droplets get into a storm updraft and are blown up to the freezing level. All storms have updrafts and most strong storms produce hail, but it often melts before reaching the ground. Mountainous areas have more hail in part because it doesn’t have as much time to melt on the way down, but Pana’s elevation is pretty typical. Just off the top of my head, luck is the only thing keeping any temperate location from experiencing hail.

Possibly, there is NOT anything unique about Pana, weather-wise, but people erroneously thought so, giving rise to the greenhouse industry there? Just a WAG.

This is like what I always hear about some location, usually where the claimant lives, that has some quirk of geography/climate that causes (severe) storms to never hit the area, even “splitting apart and coming back together”, as viewed on radar (probably because if the radar is located in the same city, there is a “hole” where the radar beam is too low to reach the clouds, thus it may show up as a hole/weak area).

It just might be the third-longest running hoax (the edit was added on April 11, 2006 by my investigation, or 6 years 10 months ago) in recorded Wiki-history.

For my next trick in deflating the pretensions of Internet pop culture: xkcd … not always that funny!

Sounds like an urban legend or a retroactive explanation to me.

I noticed that the article has since been edited:

I emailed the National Weather Service’s Lincoln office to get the low down. I bet the answer to Pana’s hail invincibility will be “Huh?”

I found this text that is apparently from a Pana centennial event in 1956. Lots of typos and garbled text, but it contains some city history regarding greenhouses. Reading this, it doesn’t seem like people chose Pana to start greenhouses because of the weather. It really sounds like one guy used a greenhouse to sell vegetables year round and it caught on locally and expanded.

I got a good reply from the National Weather Service:
