We have two more days of this weather pattern with hot and humid and partly cloudy and then big changes. High temperatures will be in the 80s on Monday and Tuesday but only in the 70s on Wednesday and 60s Thursday and Friday. Low temperatures by the end of the week will be in the 40s. Hurricane Michael is expected to come out of the Gulf of Mexico and that will break down the high pressure system and allow colder air to come into Tennessee. There could be a few afternoon showers or a thunder shower on Monday with rain likely by Wednesday and Wednesday night.
