I drive a '95 convertible v6

A couple of weeks ago I popped the hood to check my coolant and noticed it was empty, so I refilled. Today I looked again just in case and it's still fine, the tank is mostly full. A few months ago, we had the radiator and hoses replaced because of cracks.

However today I was observing the temperature gauge and noticed something a bit odd, and I'm not sure if it's normal.
Usually, the gauge stays low. Really low, like between the lowest spot and the N in the 'Normal' printed on the gauge. Today, when I was stopped, like at a red light or in a drive through, I noticed that the needle would jump up to between the N and the O, and twitch around a bit. It would fall back to a lower reading and steady once I started driving again.
Should I be concerned?
I have a long drive tomorrow, will it last? The drive's about three hours or so long, and I'll have to make the same drive back later.

There may be a poor connection in the circuit. Try the sending unit on the engine first. Disconnect and reconnect it to see if that helps.
