Potential For Cooler Air In The Long-Term

The potential is there for some much cooler air to move into the Tennessee Valley.

HUNTSVILLE, Ala. — Through the immediate future our weather pattern will be controlled by an area of high pressure sitting to our south. There will also be a large boundary sitting back to our northwest. With the high pressure system to our south we should still expect a very warm and moist air mass at least through the rest of the week. This means the opportunity for isolated showers and storms will continue. This activity Wednesday- Friday should not be as widespread compared to Monday and Tuesday. 

The warm and moist air mass will also bring temperatures in the upper 80s and lower 90s this week, before backing off into the mid and upper 80s this weekend. 

A cold front will come through Friday and Saturday, but the coolest air associated with the front should remain to our north. The one benefit we get here is the lower humidity Saturday and Sunday.

The period September 7, 2020 - September 11, 2020 could bring a pretty solid taste of Fall to much of the continental United States. It is worth noting that this time is beyond the 7-Day forecast, and the actual 7-Day does not reflect this cooler air mass.

Both the GFS and the EURO are trying to put some actual numbers on this. Do not get caught in the numbers, rather focus on the fact that both are trying to bring well below-average temperatures to the Tennessee Valley starting Thursday September 10th. The GFS tries to keep this through the middle of September.
