Visual of Fiery Heat Wave Ridge

From WeatherBell

This image of the high pressure area, or ridge, producing the massive and dangerous heat wave, clearly shows how it seems all weather disturbances will be eliminated as this incredibly dominant high pressure takes over the country.
The colors we see on the upper border are of the jet stream. Since the jet stream is used to being farther south instead of what its current position is with the ridge in place, the jet stream naturally increases in speed in response to the pressure.
That said, any storms that occur in the higher speed of the jet stream will have at least a slightly higher chance of tornadoes.
