With Weather-Display, I don't think it would show 'Snowing' unless you have a heated rain gauge AND the rain bucket tips AND the temperature is <= 32.0F/0.0C otherwise the software has no way of knowing what your local condition is.
The 'Dry' simply means 'No Rain Gauge Tip Lately'. It would modify to 'Moderate Drizzle, Light Rain, Heavy Rain' depending on the rain rate, and 'Stopped Raining' if no bucket tip reported after a while, then back to 'Dry'.
