There are some big pre-frontal storms that are moving in from TN tonight that contain very heavy rain, gusty winds, and intense lightning. At the last check the storms had 1900 strikes in 15 minutes. Although these storms have increased a bit in intensity and might even pulse up a bit more in the next 15-20 minutes, I expect them go go through a major weakening trend as they drop south. There are 3 main reasons:
#1 Look below at the chart labled "Cape", this is instability and you can see that it goes way down as it gets closer to the metro area. This will allow those storms to weaken.
#2 Upper level winds are garbage, and they converge over the metro area.... in English what this means is the winds slow down as you go towards the south in the mid levels. That means through conservation of mass the air must go down, limiting storms from getting stronger.
