Temperatures in some major league cities at about 8 pm central time

Boston 50 (with a low tonight of 44 & rain starting in 78 minutes-a game might still be going) 

New York 56 (low will be 52 with a little late night rain) 

Pittsburgh 51 (with a low of 48) 

Cleveland 46 (with a low of 46 & rain starting in 30 minutes) 

Detroit 40 (with a low of 38)

Chicago 37 (with a low of 32)

St. Louis  41 (with a low of 39)

Minneapolis 32  (with a low of 29 & wind gusts of 15 mph so wind chill will be 17)

Denver 38 (with a low of 32 & wind gusts of 15 mph)

There is no snow predicted anywhere but in recent days both Minneapolis and Denver have had snow and even lower temperatures than tonight.

So some tough weather for baseball. What would MLB do if they had a Twins-Rockies series with sub-freezing temps and snow like they had within the last week? Move the games to a neutral site? One with a roof like Milwaukee?
