Well, bearing in mind I live in Phoenix. I have some fingerless gloves from the blue collar" section at the big box stores. Mine are Wells Lamont. Runners gloves sound like something to try.

They are good down to 40F. I wear them down to freezing. However around freezing my fingertips get numb on my 5 mi commute. Only happens 3-4 times a year for me so no biggie.
