10/31/2019 7:00 AM 0.03 0.2 0.03 8.5 M Total snow depth reading will move to the location used last year on Friday (tomorrow). The reading from that location for today was 9.0". The Total Snow on the ground reading recorded today, (Thursday 31Oct19), was given from the same location as the other readings from this last set of storms to provide consistency. Starting tomorrow, 1Nov19, all Total Snow depth readings will be from the same location as used last year. This location was selected when this station initially started reporting because it is usually less impacted by wind or drifting. However, it must be remembered we are the highest location for about a one-half a mile in all directions, so wind still significantly effects readings; generally reducing the actual moisture recorded and significantly increasing varibility.
