The weather in Western Pennsylvania in winter matched that, except for the ashfall. Our region is one of the cloudiest places in the country, especially in the winter.
In the early '00s, we didn't have all that much snow over the winter months. We tended to have more cold rain. The last couple of years, we've had light snow for most of Janaury and February. Our immediate region doesn't tend to get that much snow all at once. We had a couple of substantial snowfalls in 1993 and 1994, but, since then, we had maybe one 9" snowfall. We're south of the Great Lakes snowbelt, and a little too far west to get frequent snowfalls from Atlantic winter storms. But, Western Pennsylvania can have snow flurries any time from October through April.
Since so much of the action of the book took place outdoors, I tracked local weather conditions from late February through late April 2008. Later, the curious can compare the recorded weather against scenes from the movie, to try to figure out when the location footage was shot.
The conditions described were for the Pittsburgh area. When they shot location footage in the Alleghenies, there was generally more snow on the ground, it was usually a little colder and often it was windier.
