This is the Saturday AM updated severe weather map from the Storm Prediction Center. The Slight Risk and Marginal Risk Areas have been moved south, as I thought would happen. The Slight Risk is now south of Michigan and the Marginal Risk Area just skims the Indiana border. The main risk would be marginally severe hail, mainly in N. Indiana. SPC says: “Multiple clusters of eastward-moving elevated storms are expected across the Midwest/Ohio Valley. Hail will be the primary risk across this region.”
For Tulip Time and the River Bank Run – chance of a shower or sprinkle, only a slight chance of a t-shower. Much of the time it won’t be raining. You can check the WOOD Lightning Tracker and the National Lightning Tracker.
I’ll be doing the 10 pm and 11 pm newscast this Saturday. I’ll be in the Tulip Parade (2 pm Saturday in Holland), so I don’t plan on spending a lot of time tweeting, etc. then. Stay dry!
This map from the Storm Prediction Center shows the probability of wind damage from thunderstorms for May 11. Note that the probability in N. Central IL, IN, and OH is the same as in “Tornado Alley” down in KS, OK and N. TX.
