Another shortwave trough is expected to move across the midwest and towards the Great Lakes region.At the same time guidance is suggesting an area of low pressure will move from the SW towards the great lakes by friday night. This will once again cause a cold front to move across the region that is being discussed here.
Taking a look at the severe weather parameters that will be in place..
CAPE from 500 in Eastern TN to as high as 3500-4000 across eastern Oklahoma.
Lift index goes from 0 to –2 from Eastern TN to as negative as –8 in Eastern Oklahoma back into Tx..
SWEAT index as high as 300 in eastern TN to as high as 600 across Eastern Oklahoma and back into Tx..
Energy Helicity Index is greatest from Ark to Missouri to Eastern Ok where it appears to be 1.5-2.5 which would be supportive of potential tornados.
Dewpoints are expected to be in the 60s-70s across the region as well.
All the above points out to another round of severe weather with the potential of tornados in some areas once again. At this point and time though we have not indicated on a red zone yet ..it would appear as though parts of OK (EAST) and Missouri (Central to south) and ARK (North and Central) would be part of that red zone.
We will issue a more specific detail map tomorrow including the red zone . For now..suffice to say …make preparations for another potentially dangerous day across the area.
