I attempted to find out when we last had a significant cold front in July (as opposed to one of those pathetic waves that drops the temp 1 or 2 degrees). This NOAA site suggests that it may have been as long ago as 20 years. Here's hoping you can go outside for at least a few minutes to enjoy the rareness of it.
