(AS HELICITY 0-1KM IS GOING TO BE OVER 400 M2 S2 IN ALABAMA AND TENNESSEE BRIEFLY,A PDS IS IN EFFECT AS PER STORM PREDICTION CENTER. LONG TRACK TORNADOES POSSIBLE)
Severe Weather Forecaster
Severe storms are firi
ng in the HIGH RISK NOW in southern areas of Great Lakes as the low level jet continues to intensify in the warm sector east of cold front. 4 tornadoes have been reported till now two in Illinois, one in Kentucky and Wisconsin each.
The RUC 13z run
In the newly issued RUC plot, low level jet continues to intensify and having maximum jet speed of 60kt! over Great lakes area and spreading as south as Kentucky as the intense low pressure continues to pass through Wisconsin this morning.Low level shears are excellent now and I now estimate some strong
(few though) tornadoes in Indiana and Ohio!
Due to very fast speed of storms arranged in a linear fashion, surface winds will be very strong and damaging gusts ofcourse as a result of which SPC has issued a 60% risk of winds
My tornado target remains at NE Indiana to NW Ohio area and I expect few tornadoes in morning period as later of the day, wind shears which right now are over 400m2 s2 will decrease!
