Monday's going to start out reasonably nice, but by midnight we'll see falling temperatures, rain and possibly snow.
The National Weather Service predicts patchy fog through about 9 a.m., then clear and sunny conditions for most of the day, with a high near 55 degrees.
But! It's fall in Colorado, which means nothing stays the same for long.
There's a chance of rain showers before midnight turning to snow between midnight and 1 a.m. The overnight low will be around 26 degrees.
Snow continues Tuesday morning, with total accumulation of up to 2 inches.
