Loud high-pitched noise from dash V70-XC70 2003

In the past 6 months my Volvo XC70 has had a very loud, high-pitched whine coming from the center part of the dash, perhaps in the area of the heater controls or maybe the radio. This has happened ONLY while driving in heavy rain between 50 and 60 mph. My Volvo XC70 has about 92,000 miles on it.

The last time it happened the noise stopped after only 30 seconds, the first time it happened it took about 5 minutes to stop. I've tried slowing down, turning the radio on/off, adjusting the fan speed, temperature, a/c control, air recirculation, etc. --- but nothing changes the tone or duration of the noise. It just stops by itself.

It doesn't seem to affect the car's performance, but it's very annoying and distracting. Does anyone have a idea of what's causing it and how to fix the problem?
