Good Wednesday. We could see some active weather today, particularly this afternoon and evening.
Several things are coming together to increase our chances for some severe weather later today. A warm, humid air mass already in place will interact with unseasonably cool air that will be pushing through today and tomorrow.
This clash of air masses will create some towering thunderstorms that will have the potential to produce heavy rain, lots of lightning, damaging winds, and some hail. Tornadoes are not LIKELY, but of course be watchful. The Storm Prediction Center has issued for our area a 2% chance of tornado development. The chance for damaging wind and hail is much higher at 15% (a high percentage on this index).
We have already seen, and could see a few more isolated showers or storms this morning, but most of the activity will take place during the heat of the day as we climb into the low to mid 80s this afternoon.
Storms will be possible through the evening, and we could even see some of them lasting into late tonight east of Chattanooga.
For Thursday, we will once again climb into the low to mid 80s, and the low pressure associated with the front will move by to our north, keeping clouds in the area through tomorrow afternoon, but only a slight chance for an isolated shower.
The cool, dry air will move in Friday with highs Friday in the mid 70s under mostly sunny skies and much lower humidity.
Friday night will be cool in the upper 40sl, then Saturday will be sunny with highs in the upper 70s.
Sunday will see us a bit warmer, climbing into the low 80s, but it will still be mostly sunny.
Next week looks to be dry, starting with Memorial Day which looks to flawless with a few clouds and temps in the low 80s.
