Recently, a meteorologist contacted me with some detailed weather maps and reports that show what it was like outside the day Maura crashed her car, in 2004. And now here they are for your perusal.
Says the weatherman:
It was quite cold on the morning of 9 Feb but it warmed up significantly though the day and a layer of non precipitating clouds combined with warm air moving in from the south kept it from getting super cold that night.
It was an unseasonably warm night.
I think it's just another bit of circumstantial evidence that shows it would have been quite hard to die from exposure to the elements. Especially for someone with military training, like Maura.
