Friday Morning Thoughts

Clouds and rain showers that are left over from yesterday's storms are keeping us from getting the sun out this morning. This will probably prevent a massive, widespread severe weather outbreak from occurring. However, I still think there is a good chance of some really nasty weather late this afternoon. Normally, a great deal of instability is needed to get lots of severe weather going. One of the easiest ways to get this is to get the sun out. However, this storm's power is in the winds aloft blowing strongly one way and the winds lower in the atmosphere blowing strong in a different direction. This is called "shear" and is important for tornadoes and damaging winds.

Now, lets take a look at yesterday's latest storm report map:

I want to point out the smattering of red (tornadoes) in Michigan. I checked back to see what their weather conditions were like at this time yesterday. Surprisingly, I found very similar conditions to what we have now: Temperatures in the upper 60's and low 70's, dew points in the mid to upper 60's...and most importantly, clouds. Temperatures didn't rise much above the low to mid 70's as well....yet they still got hammered.

Now...we are not Michigan and there are many other factors that will prevent us from having the extent of severe weather that they had. However, the potential is most certainly there for lots of damaging winds and a couple of tornadoes. Check back for another update probably around 12:30-1PM.
