First wave of showers/storms is passing.
New ones should pop west & southwest in the sunshine & move east & northeast afternoon-evening with isolated severe weather risk. Isolated wind, hail, tornado risk is there, along with localized heavy rainfall of 2" per hour.
Strong mid & upper flow is catching up to the storms in Clinton/Carroll/Howard. Brief tornado, gust 60-70 mph poss. Storm is a hair elevated, but rooted low enough to warrent severe threat.
This particular storm may outrun the stronger flow as it moves into Cass & Miami, causing it to weaken. We will see. If the flow can catch up to it again, it may pulse back up & rotate for brief tornado potential & produce severe gusts.
This flow will keep that isolated severe risk going through the afternoon-evening for new storms that pop.
With the sunshine out in our southwestern counties & Illinois, Marginal Risk is definite. If we can destabilize things a little more & storms intensify even more, then an expansion of the Slight Risk could occur.
The best shear & mid & upper flow nosing in is south of our area, but there is still enough here to bring a few warnings.
The current wave of showers/storms will exit. New scattered storms will pop in the sunshine in Illinois & increase. These all may eventually begin to gell together into clusters through evening & pass through our area.
