I remember pre internet days of the 1990s when I could only look at TWC extended forecast maps that they would update like once a day late morning. Those maps had light snow, snow and I think even heavy snow. Then when there was a chance closer in time you had to wait for the updated NWS forecast in the AM and PM on the local forecast. Now, there’s about 1000 different models updating all day and night to look at. lol
