All high performance summer tires can be dangerous below 40 degrees.
Maybe you should buy all season tires instead.

Toyo T1R ftw! You can also check out nitto 555, not as good as the ToyoT1R's but has a longer thread life.
Toyo T1R = Best bang for the buck imo!

When I picked up my Box in December, it had mismatched tires on the rear... replaced them with BF Goodrich GForce Sports. They were a bit slick when new (spun the damn car in the rain on a curve... luckily no one was close to me), but they are pretty good so far for the money. I still get a little cautious when it's wet.
The front tires are Bridgestone Potenzas, but I have no idea how long they have been on the car, and they're showing some dry rot, so they will be replaced soon... likely with GForce Sports to match the rear.
When they wear out, I'll probably go with Kumhos all the way around.

When you say that all High Performance tires are dangerous below 40 degrees, at what speeds are you talking about? Thanks Ed

As the temperature approaches freezing, the rubber compound hardens and reduces the amount of traction that the tire gives. Some tires are predictable and if there is not precipitation, and if you are not pushing the car, it's generally not dangerous in my opinion on most tires.

Thanks, everyone. Out of the responses I see three suggestions for the Goodyear F1s; 2 for the Bridgestone Pole positions, and a mix for the rest. It looks like there's a clear consensus that for my kind of driving in the Great, Wet, Pacific Northwest, all-season radials are a smart decision for my kind of driving.
I think I'm going to go with the F1s. They've gotten great reviews. A tad pricey, but I tend not to skimp on oil, brakes, or tires. I mean, I want the car to go, stop, and turn.
Fast. 
This is a really helpful forum!

Umm... all speeds?
See, rubber gets stiff when cold... softer tires would be more prone to getting stiffer in cold weather. Stiff tires = no traction.
