HRRR seems to like a bit of enhancement around I-70. It also keeps the low levels pretty moist after the main band moves out. Freezing drizzle? Sure would make a mess if there is.
We are in the 6-8 zone for this storm. The northern parts of the metro are going to be biting their tongues with the battle of the dry air. We shall see how much of a fight it puts up tonight!
