53mpg to 38mpg in 1 week.
I'm experiencing this drop in my FE.
I attribute it to the (much) colder weather we've been having this week (I'm in central IL) and to the fact that much of my driving is in town, so the car never really gets to warm up completely. At least, not for very long. By my estimation, nothing has changed in regards to driving style/distances/etc. Just the temperature. But it's disheartening to watch the mpg average continue to sink!
So, is a change this dramatic in my FE really the weather, or something else going on?

Re: 53mpg to 38mpg in 1 week.
I have noticed the drop also.
In addtion to the cooler temps already noted, I would add that reformulated "winter fuel" is now hitting the fuel stations, this always drops FE in any vehicle. As I was commenting to someone the other day - a 15% drop on the typical 20MPG vehicle = 3MPG, a difference yes, but certainly not as noticeable as 15% decrease off of 53MPG, a whopping 8MPG decrease!
Also, in my case, my Tires dropped from 39psi COLD down to about 36psi COLD due to the lower ambient temps. As of yesterday, I am now at 42psi COLD and have noticed a slight improvement.
For me, other causes of the drop include STRONG headwinds, and increased rolling resistance because of rain over the last couple weeks.

Re: 53mpg to 38mpg in 1 week.
My worst tank last Feb was 40.0 mpg. I live near Buffalo, and the car was fairly new. I now have:
a. Tires pumped up to about 50 psi
b. A broke in car
c. A block heater
d. More HCH II driving skills
It shoud be interesting to see how I fare. Tonight I only lost about .1 mpg on the way to work (7.2 miles). Last winter I was seeing losses of 1 to 2 mpg on my work commute. It was about 45 F. tonight, and block heater was on for about 6 hrs. I don't have a garage.

Re: 53mpg to 38mpg in 1 week.
I'm from central Illinois, and I too noticed the sudden drop in FE. I thought I was getting pretty good at achieving 50+ mpg. After filling up late last week, I was only getting 36 mpg! I've struggled to pull it back up to 44 mpg.
I was considering getting a block heater, but I'm not sure that it would pay for itself...
