This is one operational run… and a lot goes against snow accumulations in April (high sun angle, marginal temperatures, etc.)… The main point to drive home is that there may be a conversational snowfall on Saturday.

More importantly, take a look at how low the mercury may go this upcoming weekend:

Low temperatures on Sunday:  BRRRR! Lower 20s with 10s in the mountains!

High temperatures on Sunday — With sunshine temperatures should moderate a bit into the upper 30s to near 40 degrees!

    LOL I saw a comment on CWG’s facebook page where someone tied this to climate change. HAHA! Avg last frost date hasn’t even arrived yet.

    While is probably will snow here, maybe for several hours, getting it to stick and accumulate this late in the season is problematical. Maybe an inch or so on grass in shaded areas?
