A thunderstorm in 45 degree weather in January. Don’t thunderstorms need a lot of heat to form?

Pretty common even in lower temperatures from 30 upwards. And since it’s Summer, yeah, that temperature’s pretty common.
EDIT: It just occurred to me that this is probably not a “middle of australia” question where 45C (113F) is common at this time of year and more of a “middle of usa” question where 45F (7C) is common at this time of year.
No. They need powerful updrafts. These are generally created by differences in the heat in certain air currents. If one air current is 45 degrees Fahrenheit and one is 55 degrees Fahrenheit, you get similar updrafts to what you would get if they were 80 and 90.
Thunderstorms need convection and moisture. As long as moist air can rise and cool to start a convective cycle, a thunderstorm can form.
It’s not high temperatures they need it’s high temperature **differences**. Interesting weather occurs when you have high energy and low energy areas close to each other. The violence is part of a new equilibrium being reached.
