Published at 10 am Friday
This is going to be a prelude to my main update this afternoon. I am starting to see some higher amounts come out of the models for our area. Don’t get too excited, I have not been expecting much. I am also seeing a little later start with the snow tomorrow morning. I should have time to post my final forecast Saturday morning after the high-resolution models come out.
The first advisory is for the Northwest and Southwest San Juans. The 8 to 16 should be read as 8 inches for the Southwest San Juans with up to 16 inches for the North West San Juans. This will be dependent on what type of leftovers flow over the divide on Sunday.
