fr/Storm Central:

A major low pressure is forecasts to deepen and slide north northeastward into the Chicagoland area. With this, a warm front is going to ride above while a cold front slips to the south. The huge contrast from Warm 70-80 degree temperatures with warm moist gulf air is going to have these storms popping near the Mississippi River on Friday. With the lower level jet stream being farther to the south, a clash of air masses coupled with strong forcing and dynamic cooling is going to quickly get these storms tornadic. Unfortunately, it currently looks like a widespread outbreak. A tornado outbreak means at least 10 tornadoes occurring with a system. Forecasters at Storm Central think this could very well be worse than Tuesday’s or Wednesday’s storms.

Since we are dealing with such a strong low pressure, shear levels are going to be through the roof. With that being said, storms are going to quickly become super cells and have a much higher threat to become tornadic super cells. While it is impossible toforecast the exact path or city a tornado will impact, Storm Central has laid out a diagram where the all the ingredients will come together.
 Please prepare for the potential for long lasting strong tornadoes to occur in any of the Red or Pink areas. While all areas will likely not see a tornado warning, most areas are likely to be under a tornado watch sometime on Friday or Friday night. What is dangerous with this upcoming system is that storms are not going to stop overnight. Tornadic storms could go well into the overnight hours as they did Tuesday night. While the areas are subject to minor changes, a firstforecast is out and this is likely to be a big event.

Storm Central will be updating on Facebook with update posts, watches,warnings and more. We have proved ourselves Tuesday evening as a great helper to alerting others and we would like to help you as well. (LIKE) Us on Facebook for the latest!

This is certainly not the only topic we are discussing. Another potential Blizzard may impact Iowa, Minnesota, and Wisconsin this weekend. Model runs are placing out over a foot of snow with 40mph winds. While this is not set in stone, it is certainly something to watch very closely as If this does occur, a big storm for many!
