A few days ago, Chicago hit 100 when the heat dome expanded up there. However that was just winds ahead of an early season cold front. The cold front has cleared the Midwest, they are mild and cool in the low 70’s for highs.

Right now the cold front is attempting to penetrate central Texas. It’s having a lot of trouble. Before it arrived the temps were 107. There are 3 competing air masses - humidity from the Gulf pushing from the southeast, desert winds from the southwest, and north winds from the arctic high pressure up north (this is not a heat dome but a cold dome relatively speaking).

This battle is playing out as we speak. There could be lightning, thunder, rain, hail but fortunately no threat from tornadoes (our dew point is just dry enough to prevent it).

The cold front will win this battle, but it’s a very minor win. The highs tomorrow will go down 8 degrees from 107 to 99 before the Texas sun takes back over. But hey we’ll take it.
