The heat wave continues through Wednesday along with a final round of isolated to scattered strong to severe thunderstorm potential for Wednesday as a cold front will move through bringing an end to the heat wave starting Thursday. The headlines depict the current thinking. Key factors for Wednesday include:
1.) Timing of the cold front and thunderstorms to move in close enough to max heating to take advantage of high levels of instability.
2.) Ability for the complex of strong to severe thunderstorms to sustain itself if it arrives later in the evening.
3.) Whether certain limiting instability factors can be overcome by other more favorable instability parameters similar to Monday.
4.) Level of wind shear is a bit less than the minimal criteria for severe thunderstorm development but may be overcome by factors 1-3.
