Now it looks like a third line forming directly behind the second line.


Tornado in Lafayette Indiana.

This one was confirmed by radar and spotters who called in when they saw it. This is a classic case why people in the slight-to-marginal risk areas should also pay close attention to the weather. It's easy to assume that moderate risk areas is where all the severe weather will occur but it can occur in the  slight risk and marginal risk areas too.

Warm air "capping"?

There's lot's of discussion about this on twitter. We'll see how it turns out.

The second line of storms is almost here.

The second line of storms is approaching the Illinois / Indiana state border. There's a tornado warning in Effingham, Illinois right now. The estimated speed of the line of storms is between 55-60MPH.

We also saw a little bit of sunshine but not much. The temperature shot up to 69 degrees while the dewpoint sits at 60 degrees.  This second line of storms is the main event. It would be best to stay inside and turn on your weather radio if you have one and check the radar.

It's not over yet.

Remember that the tornado watch lasts until 8:00pm. The second line of storms is still in Missouri and moving off to the east. There's a lot of sunlight that can break through between now and then.


Good news! The storm weakened.

Sunshine just came out in Bloomington Indiana.

It's 11:56am and the sun is shining. That's bad news for this evening. This will add fuel in the form of heat and instability to atmosphere for this evening. Still no tornado watch posted for southern Indiana yet but, the NWS has issued a "Situation Report". In the report is states that,

"Individual Storms tending to track more east or east-southeast bound will have higher tendency to produce tornadoes."

So, if you have access to weather radar you'll definitely want to pay attention to how the individual cells are moving. Tornadoes are cyclonic and spin in a counterclockwise formation so any cells tracking southeast have the greatest severe weather potential.





Southern Indiana should be under a Tornado Watch for tomorrow.


From snow to 70 degrees and thunderstorms

Our season's first sever weather will likely happen overnight tonight and into tomorrow. My main concern is the damaging line of storms that forms after the low pressure crosses the Illinois / Indiana state line. See below.


Believe it or not, after this there's still more chances for snow heading into the weekend.
