Heads up! THIS is coming next week! Do you see what we see?
What you should be seeing is the Greek letter "omega", or "ω". The so-called "omega block" pattern gets its name because the jet stream traces a ω pattern. Those two sagging circles are low pressure systems, which spin counterclockwise. Farther north, a high pressure system can be seen in red spinning counterclockwise.
The opposing spin of each system means the three – the low, high and low – are like interlocking gears. They don't budge, spinning and feeding into each others' spin for days.
Beneath the low pressures, expect unsettled weather, cooler temperatures and cloud cover. 
Beneath the high, in the red, southern Canada and much of the northern U.S. should see sinking air, bright skies and above-average temperatures.
There's a chance the western low may pump north moisture, setting the stage for severe weather over the High Plains on Monday, Tuesday and Wednesday. I'd be closely watching West Texas, eastern New Mexico and perhaps western/central Oklahoma.
