A 1002 mb low will move across Iowa into Northern Illinois on April 15 2023 swinging a cool front/dry line across Arkansas and the Mississippi River Valley. Hail, wind, and isolated tornadoes will all be possible with this system. Slight Non-polar CH4 release is expected from tree stems, and shallow water systems such as ponds, creeks, rivers, and lakes. Slight NO3 levels are expected from CAPE buildup and polar positive lightning strikes to develop a severe weather threat. NO3 will slightly tighten with soluble H20 to create a slight atmosphere for ground tornado development. Hail, isolated tornadoes, and wind threats—information through measurements depicting severe storms from Illinois to near Little Rock to Texas as earlier stated. Measurements are running .34, .32, .22, .23, and .22 which is a little stronger than yesterday but still below. the .37 threshold of dangerous tornado potential. Basically, EF-0 to EF-2 tornadoes could play out as of the latest measurements in an isolated fashion.
