Rain chances this weekend in Colorado

Tomer’s Take:

• A surge of Monsoon moisture is moving into Colorado.
• This means afternoon rain/t-storms are more likely through Monday.
• Precipitation chances for LT100 and Triple Bypass are increasing.
• Early and late precipitation is now possible especially in the Southern Mountains.
• Snow is possible both Saturday night and Sunday night on the 14ers. Light accumulations.
