Broad upper-level ridge of high pressure continues to dominate the scene around here, but there is a stalled frontal system that lingers in the lower part of the atmosphere. As a result, it’ll stay unstable in the Tennessee Valley as we head into the weekend and early part of next week with a daily chance for daily showers and thunderstorms. A stronger frontal system will approach the area around Tuesday of next week and this is likely to enhance the chances for showers and thunderstorms.

Broad upper-level ridge of high pressure over the northern US will remain firmly established during the next few days while an upper-level trough pushes away from southeastern Canada. The combination will produce a northwesterly flow of air at upper levels of the atmosphere which will push a couple of weak frontal systems in our direction. These fronts will bring us moderate chances for showers and thunderstorms in the Tennessee Valley as we head towards the weekend and high temperatures will generally fall in the lower 90’s.

Broad upper-level ridge of high pressure over the Great Plains will remain firmly established during the next few days while an upper-level trough amplifies over the Northeast US. The combination will produce a northwesterly flow of air at upper levels of the atmosphere which will push a couple of weak frontal systems in our direction. These fronts will bring us small-to-moderate chances for showers and thunderstorms in the Tennessee Valley as we go through the week and high temperatures will generally fall in the lower 90’s.

Broad upper-level ridge of high pressure over the Great Plains will remain firmly established during the next few days while an upper-level trough amplifies over the Northeast US. The combination will produce a northwesterly flow of air at upper levels of the atmosphere which will push a couple of weak frontal systems in our direction. These fronts will increase chances for showers and thunderstorms in the Tennessee Valley as we go through the week and high temperatures will generally fall around the 90 degree mark.

A cool front will approach the region later today and it will add to overall instability around here for the next couple of days. As a result, there can be additional strong thunderstorms in the area as we head into the weekend and some of the rain that falls can be heavy at times. One tropical wave will continue to head westward along the Gulf coast today and there are other disturbances to track in the Atlantic Basin as this somewhat favorable pattern for tropical activity continues into next week.

Abnormally strong upper-level ridging continues to dominate the scene in the northern US and the resultant hot, humid weather around here will continue through the weekend. The center of this high-level ridging will retrograde westward over the next few days and become centered over the interior western US by the end of the week. A frontal system will slide from the Great Lakes by the end of the week into the Mid-Atlantic region and it is likely to increase instability around here this coming weekend.

Upper-level ridging will expand and intensify over the Mid-Atlantic region during the next few days and temperatures will respond here by climbing to the 90’s this afternoon and likely to repeat this on a daily basis well into next week. The heat will be accompanied by uncomfortably high humidity levels and there is little chance of relief from rainfall which will likely be quite scattered. This high heat and humidity will continue into at least the latter part of next week.
