Cheap DIY way to dehumidify a basement during a rainy spell?

What is the best creative way to dehumidify a basement without buying an expensive dehumidifier? I don't want to run one constantly, but with all the flooding rain, I need to do something.

I live in Southeast Missouri, land of flooding rainwater at the moment. I rent a townhouse and I have a basement that is 1/2 finished with the other 1/2 simply a concrete room, separated by a paneling wall and door. I use the concrete room for laundry and storage. The finished room is where a bookshelf, my file cabinet, printer, dining table, and TV sit. I tend to use it for a home office...so not a lot of "living" down there but some.
It's been raining like a cow peeing on a flat rock for over a week, so everyone and everything is waterlogged. I do have 3 leaks in the basement, but I manage those by soaking up the water with towels then laundering them. The water hasn't completely covered the floor but will make large puddles if left alone. I pulled up the carpet in there this weekend because it was funky and I was tired of it (and could immediately tell a difference in the air quality based on my allergies). Now I have a solid concrete floor and three outer plaster/cinderblock walls (other walls are paneling and studs...not sure there's insulation in them).
Knowing that the rain won't last forever, and that normally the basement isn't that damp, does anyone have any ideas on how I can lower the humidity down there without spending $150 on a dehumidifier that I probably won't use forever? I have a couple of fans circulating the air right now. Anything creative I can do? Should I be running the central air conditioner (it's in the 50s today though...too cold!)? The heater? What about an electric space heater?
I'd guess the part of the basement I'm concerned most about is about 10ft x 10ft (maybe 10ft x 12ft...not good with judging distance!) with a door at the top of the stairs (leading into the living room) that I leave open for easy cat access. You can definitely tell where the air changes on the stairs though, both in temp and in humidity.
Any and all ideas welcome!
