Another Too-Late Tornado Warning

By -
This has become far too common. Another obvious tornado warning situation where the National Weather Service in southwest Wisconsin waited too long to issue a tornado warning. Jeff Piotrowski, I, and a third meteorologist were tweeting about the threat but the NWS didn't issue a tornado warning until the storm was on the ground, lofting debris. Let's pick things up at 1:34pm (the time my tweet, below, appeared on the timeline).

The rotation continued to increase. I was shocked by the fact a tornado warning had not been issued. 

Again, it was shocking to me that a tornado warning wasn't out.
Finally, at 1:48, the NWS issued a tornado warning.

The problem is that the tornado had already been on the ground for at least two minutes. 
The bottom display of lofted debris showed a considerable area of debris at 1:46pm -- two minutes before the tornado warning was issued. The rotation display showed an obvious tornado signature. Using an experimental program, the tornado was estimated to be EF-2 intensity. 

I'm not aware of any injuries or significant damage from this tornado which, fortunately, occurred in a rural area. There were injuries with the unwarned tornado northeast of downtown Philadelphia July 29. I fear it is just a matter of time before needless fatalities occur as they did in Joplin.

This is yet another reason why our nation needs a National Disaster Review Board.

The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue is 0.1 to .25 inc
