Hazy sunshine & torrid heat will dominate today with highs 91-98 with heat indices 98-108.
A couple of rather diffuse outflow boundaries from storm complexes to our north & northeast will traverse area this morning & this afternoon. We will monitor to see if an isolated storm or two can overcome cap & form on these.
Otherwise, it is just a dry day with not the best air quality & high Ragweed & warm-season grass pollen.
Wednesday looks dry, hot & hazy with highs 92-98 & heat indices 99-108. Any storms will be well north & northeast of the area & outflow boundaries should not reach any farther southwest than a South Bend to Wabash & Marion line.
A few spotty storms are possible Thursday. I went with 30% coverage with highs in the 90s & heat indices near or +100 again.
Hurricane Laura will mke landfall & more or less absorb whatever is left of Marco, then pass over Kentucky as a tropical depression Friday-Saturday.
Meanwhile, remnant Hurricane Genevieve circulation will continue to deepen from Iowa to Wisconsin as it encounters upper jet streak & upper trough. A surface cold front will also be moving southward with the tropical airmass ahead of it.
This all spells severe weather risk for us later Friday-Friday night. SPC already has SLIGHT RISK up for the viewing area.
Early to mid next week also features the risk of storms with some severe weather risk as cold front moves back north as a warm front & storm system(s) approach with reasonably strong flow aloft.
