More Seasonable Weather On Tap for First Week in September


After last week's heat and a couple of days of scattered storms more seasonable weather looks to be on tap for the upcoming week. This is thanks to a cold front which has shifted the wind from southerly to northerly, ushering in drier, slightly cooler air into the Mid-South.


Above is a surface analysis from NOAA's HPC showing the cold front which has passed through the area. This has dropped our dew points into the lower 60s which is much more comfortable than the mid 70s we had been dealing with last week. In addition to lower dew points, temperatures also look to be primarily in the upper 80s, giving us some decent relief from the previous mid to upper 90s.

Pictured above is the GFS modeled mid-level moisture for Tuesday night. This shows a huge lack of moisture over the Mid-South which indicates no cloud formation is occurring. This is due to northwest flow from the large ridge of high pressure well to the west of the Mid-South. This area of high pressure is preventing any waves of energy from making their way into the area which would otherwise provide uplift for cloud formation. In addition, this northwest flow prevents any significant warm air advection from occurring which would also lead to uplift. As a result, sunny skies and fairly pleasant temperatures are in the forecast for the rest of the work week.
