Exactly how much the Mile High City will get remains to be seen. They could get a couple of inches or 20 inches but I suspect somewhere to the west in the High Country will get hammered by 40+ inches!

This system will draw on heat and humidity off the Gulf, keeping the flooding rains going. Especially during the heat of day!

This system will ultimately recast the atmosphere, pulling in cold Canadian air once again.

GFS shows not one but two decent cold shots next week on into the following week but check out the heavy rains along the East Coast and also the system pushing into California. Also notice the snows the models depict across the Upper Midwest as colder air wraps around the center as it lifts into Ontario.

GFS 5-day mean 500mb height anomalies shows the flip coming nicely.

New York City officially reached 71 degrees yesterday, the first such since Oct 29th and the first 70+ milestone of 2015. Boston has yet to hit their first 70.

See today’s video for the discussion.
