The yellow zone is the equivalent of a slight risk.
The Gray area represents a 5% risk area or low risk area.
Severe Parameters
CAPE 500-3000 depending on your location..
Lift Index is 0 to –8 depending on where you live in the zones.
Mid Level Lapse Rates 5.0 to 8.5
Shear is 35 knots +
Trigger is a low pressure which should be strengthening and moving to the NE towards the Dakotas late in the day with a cold front that trails to the south from the north..
Dry line will stretch from North to south ahead of the cold front.. Once again this dry line will be the focus of the severe weather but again there will also be a CAP in place.
This CAP should be overcome with the warmer surface temps which should help to moisten the lower levels of the atmosphere..
There will be the potential for tornado’s but again the main threats should be hail and damaging winds along with some very heavy rain across the zones..
