August, month-to-date, is running bone-dry. Officially, IND has only accumulated 0.18″ of rain, but that may be changing as early as this afternoon and evening.
We note high resolution, short-term data is becoming more aggressive with the development of showers and thunderstorms this afternoon and evening. Initially, storms will impact w-central parts of the state before encompassing more of central Indiana. The following are images of what the local radar may look like at 4p, 6p, and 8p.
With leftover boundaries from early morning storms across northern parts of the state (likely will serve as a “trigger” for PM storm development), combined with a hot and muggy airmass, confidence is increasing on numerous showers and thunderstorms across central Indiana this afternoon and evening. Widespread heavy rain isn’t expected this afternoon, but localized hefty downpours are a good bet with precipitable water values (PWATs) approaching 2″ this afternoon.
Unsettled times remain Tuesday before a much cooler regime looms for the second half of the week…
