July 18 | Evening Forecast with Chief Meteorologist Keith Gibson
INDIANAPOLIS (WISH) — Prepare for an active and swampy weekend with several rounds of showers and storms. This will include risks for flooding and severe storms.
Friday night: We look to increase rain chances closer to the pre-dawn hours of Saturday. Lows in the low 70s.
Saturday: We are gearing up for several rounds of activity this weekend that gives way to flood/severe risks beginning Saturday morning. Mid 70s dew points + increasing dynamics aloft are leading to this active pattern. Rainfall rates within the heavier downpours will be up to 1-2″ per hour, which could cause some localized flash flooding.
Pinpointing exact timing is still difficult. There looks to likely be scattered showers/storms in our area Saturday morning before a storm complex rolls in Saturday afternoon-evening. Additional development may occur late Saturday night into early Sunday morning.
A level 2/5 slight risk is in place due to the Saturday afternoon-evening complex for a threat of damaging winds, and there could be some embedded rotation at times.
Highs in the mid 80s with feels like temperatures pushing the mid 90s.
Sunday: Additional development may occur at times throughout Sunday with very muggy air persisting. There is also a low level 1/5 severe risk for damaging winds. Flooding concerns will remain prevalent with highs in the mid 80s.
7-Day Forecast: Rain and storm chances remain elevated through Monday before a hot dome begins to take over the area. This dome will bring us sweltering heat and humidity into mid to late next week and reduce rain/storm chances to isolated pop-ups. Highs look to soar into the low to mid 90s with heat index values over 100. At this point, we’re likely heading towards heat alert territory.
