Severe Thunderstorms With Isolated Tornadoes Possible

3:30pm UPDATE
Nothing out there yet...Pressure is falling rapidly. Dewpoints are still pretty low except in west Ky. Cloud cover increasing in west Ky. Best chance for storm initiation is within a couple of hours there. Afterward, storms could still fire up but will they be able to overcome loss of daytime heating? Perhaps...

SPC has put out a mesoscale discussion for parts of our region, particularly areas of west Ky and west IN and along the Ohio river. Tornado watch MIGHT be issued depending on how things unfold.

-------------------------
Looks like it could be an active day for us spotters. Barometric pressure readings are falling off of a cliff, indicative of a rapidly intensifying storm system. In just 3 hours, barometric pressure has dropped nearly 0.15" Hg or roughly 5 mb. That's significant. My pressure reading as of 12:45pm is 29.44". It has dropped 0.02" Hg in just the past 10 minutes!

What does this mean for Louisville and the rest of our region? Look for the potential for severe thunderstorms this afternoon. NWS office in Louisville thinks severe activity should be scattered. Since the atmosphere is generating much twist in the upper levels, the dynamics are in place to support tornadic cells. Let's hope not. Damaging wind looks to be the main concern.

Keep your weather radios in alert mode. If you haven't purchased one yet, get one at your nearest home improvement center or any retail/grocery outlet, preferably one with S.A.M.E code technology. Easy to program the codes that you need to alert your area or any areas near your location.

Here are the codes below...

S.A.M.E. codes for Kentucky
S.A.M.E. codes for Indiana

Stay safe out there...
