Jumpy speedo and tach

I get a 'jumpy' speedo and tach when first starting the car and the temp has been in the 20's F (or below).
Basically the speedo and tach both jump up to where they should be and then drop back down to zero.
Once the car warms up everything is fine.

Anyone else experience this?
