Rain or condensation can cause havoc with many electrical systems; especially if there are exposed wires or components that are getting wet. This can cause short circuiting situations and gauges to "act weird" like you’re describing.
As there are several potential causes of these problems, the best bet is to have a local ASE certified mechanic complete an electrical component inspection in order to determine what is causing the issue so it can be repaired quickly.
