Forecast period: 08.18.19 through 08.25.19

7-Day Precipitation: Rainfall is expected to run near average through the forecast period. We’re forecasting widespread 0.50″ to 1″ amounts to be common across central Indiana, but there will be locally heavier amounts where strong storms track.

7-Day Temperature Outlook: Temperatures are expected to run near average through the forecast period- balanced by a warmer than normal open to the period and cooler than average close.

Severe Weather Outlook: An active weather pattern will remain with us through the 1st half of the new week. In addition to the threat of severe weather today, we’re also closely monitoring the potential of strong to severe storms Tuesday night-Wednesday as a cold front slices into the hot and humid air mass in place. The pattern will turn much calmer once we get to the 2nd half of the week as cooler, drier air builds in.

Day 1: After a quiet start to our Sunday, a line of thunderstorms is expected to form to our northwest this afternoon. That line should move southeast and begin to impact central Indiana late afternoon into the early evening hours. Some of the stronger cells will promote the chance of large hail and damaging straight line winds.

Day 3: Scattered thunderstorms will remain in the forecast Monday, but widespread severe weather isn’t anticipated. As we look ahead, a cold front will slice into the hot and humid air mass in place across the Ohio Valley Tuesday night into Wednesday. As you might expect, the clash of air masses between significantly cooler and drier air behind the boundary will lead to scattered to numerous storms during the transition. Accordingly, we’ll need to remain on guard for the threat of additional severe weather (threats similar to that of today) during that time frame before much quieter, calmer weather takes over Wednesday night into next weekend.
