You definitely need to go hon. Being able to time them thus early is a sign of preterm labor.
I would go if it was me. I know how it is with the snow and the long hospital drive I have one ahead of me in a few weeks and the snow is starting to get bad but if you can time them I think you should go
My Dr told me to go with the 511 rule, five contractions, lasting a minute, for one hour then go in
I would call your doctor first
