Updated Tornado Forecast for This Afternoon and Tonight

By -
Updated Forecast on the Blog. Scroll Up.

The above is the tornado forecast from the NWS SPC. While this forecast is in effect from now until 7am Saturday, the threat for tornadoes probably will not start until 1-2 pm. This is earlier than earlier thought. Based on very late data coming in as I'm typing this, I might extend the red area to Jackson, Tennessee.

The color codes:
Red + hatched = high risk of strong tornadoes. A strong tornado is defined as a "2" or stronger on the EF tornado damage intensity scale.
Yellow + hatched = enhanced risk of strong tornadoes.
Brown = significant risk of tornadoes

How to Prepare. Because of the likelihood of power failures (see wind discussion below), the preparations are important.
  • Prepare to care for infirm friends and relatives now. Don't wait until the storms are approaching. 
  • There is a significant risk of power failures. It won't hurt to get a few extra bucks at the ATM.
  • Put your car in the garage along with any lawn furniture or other items that may be damaged.
  • Fill your car with fuel.
  • If you are running low on prescriptions, go ahead and get them refilled.
  • If you have a portable generator, make sure you place it outdoors, well away from any air intakes.
Damaging Wind Likelihood
In the red, hatched area, straight-line thunderstorm-generated winds may reach 90 mph. If this forecast is correct, widespread power failures will occur. Because leaves are back on trees in this area, the power failures will likely be worse than they would have been a month ago.

I will have an update early this afternoon.

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 i...
