Bad Astronomy talks about the odds of getting killed by one as 1:700,000. But this includes extinction events, etc. You are more likely to die by meteorite than terrorist apparently.
I couldn't find any odds of getting hit by one, never mind two falling in the same area within the space of a couple of weeks, but I think it would be much lower than getting hit by lightning (1:960,000). About 500 meteorites hit the earth each year. There are 138 million lightning strikes per year. So, not accounting for population density, I would estimate that your odds of getting hit by a meteorite is 1:265,000,000,000 (1 in 265 billion).
