Apr 02 - Snow commenced again at 3AM with a heavy snow squall with thunder before daybreak, diminishing to a steady light snow during the morning. Moderate to often heavy snow commenced late morning and continued through mid afternoon, gradually diminishing to mostly light and moderate snow by early evening, then light snow through the evening. Heavy snow squalls during the day often dropped visibility to near zero. Thunder was heard several times, including once during the evening when the event was winding down. One of the most interesting weather days in the nearly ten years that daily obs have been taken here, particularly in view of the fact that the NWS forecast never mentioned the possibility of it, even during the height of the storm.
