I'm happy to say that this is one debate which can probably be put to rest. This is not to say there won't be detractors. Of course, there will. And while I'm semi-sympathetic, I'm now firmly against the notion of adding a roof to our new ballpark.
This is strictly based on a little bit of weather and postponement research.
Data on postponements and weather-related delays is rather difficult to come by. As much as I respect RetroSheet.org, they have nothing on the subject, but do promise that it will be added to their "schedule" database over time. (Don't take this as a criticism of their work. Far from it. They have done amazing things to make baseball data easily accessible to anyone interested in research. This is one of the very few holes in their data which will, no doubt, one day be plugged.)
Roofs in the Majors
Rogers Centre (formerly SkyDome)
Chase Field (formerly Bank One Ballpark)
MinuteMaid Park (formerly Enron Field)
The best (and only, that I know of) place to find the data is on the individual team web sites, which carry schedules back several years. They show each game as it was originally scheduled and indicate either a final score or "PPD" meaning the game was either not played or not finished. Occasionally, they indicate ties where a game was cancelled before being completed.
So I started with 13 ballparks without roofs in places which are somewhat similar in climate, leaving out California, Texas, and Florida. Then I looked at the period from April 2004 to May 2006.
The table shows the parks with their total postponements over the period (which I'm assuming are all weather-related).
You'll see a total of 65 postponed games over two full seasons plus two months. During that same period, these parks hosted a total of approximately 2457 games, for an insanely low postponement rate of 2.6%.
This does not consider late starts, delays during a game, or extremes of temperature. I'll certainly look into this if I can find a good source for the data.

*some data was missing
So there's nothing here about the comfort factor for the fans, nor does it say anything about how bad weather affects walk-up ticket sales (it likely has minimal effect on season ticket sales). Nor does it touch how conditions affect the quality of play. I'll leave those for others to investigate.
But on 97.4% of the days that people went out to the ballparks, a game was ultimately begun and completed. That's pretty amazing. I would have guessed that more games were cancelled, but I would have been very wrong.
Still, no other market has weather conditions quite as extreme as we do (I think this is true). We will, after all, have the ballpark farthest north without a roof. So there is more to be examined.
Tom Mee, the Twins' official scorer, has been with the club since it moved to Minnesota. He said grim weather was more memorable because it forced the team to reschedule games.
Mee remembers a summer day when the outfield light standards bent and swayed while a tornado was skipping nearby; an early spring game played under protest by the Yankees because the game-time temperature was 31 degrees (the Yankees won and dropped the protest, Mee said), and a day in 1965 when three players who lived in Burnsville had to be delivered to the stadium by helicopter from their homes across the flooded Minnesota River.
On Sept. 20, 1965 -- a mere six days before they would clinch their first American League pennant -- the Twins drew only 537 people to a makeup game in the rain with the Kansas City A's; it was their lowest attendance ever.
Plow the snow, play ball!
"For one opening day, in our first or second year, we had to plow the snow off the field," Mee said. "We delayed the opener for an hour or so, to let the field dry off." Indeed, Opening Day of 1962 brought a high temperature of 34 degrees with an official snow cover of 2 inches.
But Mee also recalled that there were some splendid mid-April home openers at the old Metropolitan Stadium, the two warmest coming back to back in 1976 (a 78-degree high) and 1977 (79 degrees).
Four postponements in 81 games is a 5% postponement rate, a bit higher than the MLB average, but that is to be expected here.
Miller Park: Gymnasium with skylight (Source: RP)
But it's hard to claim that a 5% postponement rate is sufficient to justify spending another year and $150 million to accommodate. This is especially true when, as noted in the comments left about yesterday's article, it's nigh on impossible to design a roofed stadium which feels like an outdoor stadium. The support track and other mechanicals -- not to mention the retracted yet still visible roof itself -- effectively boxes the park in and gives an enclosed feeling which defeats the purpose of opening it at all.
This effect is especially pronounced at Miller Park, where, even with the roof open, it still feels like a big gymnasium with a skylight. There's nothing "outdoor" about that park at all.
This is an issue which is bound to raise its head again, but now we can be prepared -- aremed with statistics -- to fend off those arguments.

Of 83 scheduled games, a maximum of 22 (or 27%) could have been impacted by rain. Of those, 12 were possible to result in cancellation or postponement.
These are conditions at game time, but I also considered data from a few hours before the game and during the approximately 3 hours when the game was being played. It's hard to know exactly how hard the rain was falling, so these can only be guesses at what umpires might have decided. In fact, the teams and the umpires want the game to be played, so they likely would have cancelled less games than it may at first appear.
"You talk about the magic, the aura, but what really makes a stadium is the fans. Concrete doesn't talk back to you. Chairs don't talk back to you. It's the people who are there, day in, day out, that makes the place magic."

Seville's certainly will benefit from 81 games a year played about a block away! (When I walked by on this day, the place looked deserted, but I stand corrected!)
Brick work just inside the opening matches the color of the limestone - per Jerry Bell's requirements.

Compare this picture, from the open house in March, with the one above and you'll see that some furniture reconfiguration has taken place.

Off-topic, but this gigantic, cool, retro sign is just across the street from S&CH. Why? I don't know. Might look nice on top of one of those municipal parking ramps...
This is what I was working on while my photo was taken (click to see a VERY BIG version).

This looks south and shows the track configuration for Northstar. The platform shown is just a placeholder. To the best of my knowledge, concept drawings for this platform have not been released. Keep in mind, this is NOT part of the ballpark project. It is completely separate.
In addition to the Pro Shop facade, you can see more gravel being laid before the final plaza surface is poured.
The rules were clearly posted next to this new entry point on the Seventh Street side. I have no problem with the rules!
