The preview to summer-time weather continues into Tuesday. The light winds and building temps will allow the pollutants to building up during the afternoon/evening...hence the Air Quality Alert for the Louisville Metro. Highs will reach today's levels, plus 1 or 2 degrees higher.
Wednesday looks quite warm...if not just plain hot. South winds and decent sunshine will allow highs to increase again...another 1 or 2 degrees. The moisture will increase as well, so an isolated pop up thunderstorms can't be ruled out.
Wednesday night is when the setup starts to change....
A cold front will move in from the west during Wednesday evening/overnight. Expected scattered showers and thunderstorms as a result. Instability is there, but the wind shear is lacking. So organized severe thunderstorms are unlikely, but a few strong storms that could push the wind limits on a warning...may take place. This would be especially true of areas west of I-65 in the evening. Most will just be typical thunderstorms.
Thursday--the front crawls into central/southern Kentucky. Instability will suffer due to clouds, so just scattered showers with some thunder expected.
Friday--the front starts to "wash out" over southern KY/TN. Spotty showers still possible despite that.
Saturday-- moisture levels start to increase yet again. A few showers/thunder possible.
Sunday-- and second front will march through during the afternoon. A period of rain/thunder expected. A deep moisture sounding is lacking, so the severe threat looks limited. We'll watch that.
The best news of all...that second front will lower dewpoints even lower to allow for a below normal temperature period and dry weather. The video explains what may happen after that.
See ya on TV!
