After a seasonably cool night tonight, a wave rotating down the west side of the past storm, currently located in North Dakota, is forecast to rotate through northern Colorado on Wednesday and reinforce the current cool spring airmass, bringing breezy conditions over our area with a chance of afternoon showers.
After another cool night Wednesday, Thursday will be warm and mostly sunny before another wave rotating around the same storm may bring some cooler temperatures to the area for later Friday into early Saturday, though at this point it is uncertain whether this airmass will make it over the Continental Divide.
Otherwise, most of Saturday should be nice until yet another wave rotating around the longitudinally expanding old storm mixes with some Pacific energy and brings the threat of some afternoon showers.
Meanwhile, a Pacific storm is forecast to cross the Pacific Northwest coast late Saturday and drop into the Great Basin by Sunday. Transient ridging ahead of the storm should bring a warm and breezy day for Sunday before complicated interactions are forecast to occur between the Great Basin storm, additional upstream Pacific energy and additional energy still rotating around the old storm that affected us this past weekend.
While the details will no doubt evolve as we get closer to the event, another round of cool and unsettled weather with periods of precipitation look to be on tap for most of the next work week.
