428 FXUS63 KIND 151101 AFDIND Area Forecast Discussion National Weather Service Indianapolis IN 701 AM EDT Wed Jul 15 2026 .KEY MESSAGES... - Generally dry weather and a steady warming trend mid to late week - Peak heat indices around to slightly above 100 degrees each afternoon mid-late week - Chances for showers and storms return Friday through the weekend, primarily during the afternoon and evening && .DISCUSSION (Today through Tuesday)... Issued at 304 AM EDT Wed Jul 15 2026 High pressure will continue to influence the weather over the region through at least Thursday, bringing hot and precipitation free conditions. Highs over the next few days are expected to reach the low to mid 90s with heat indices near to slightly above 100 degrees. The stagnant and suppressed air will also lead to greater ozone and lower air quality for parts of Indiana today. The high pressure will start to break down by the end of the week, and models are showing better agreement on an upper wave bringing good chances for showers and storms Friday. Aloft, NW flow will set up with a surface low prompting additional precip chances Saturday. After a brief break in PoPs, models show another system to move through early to mid next week with a decent chance of cooler temps moving in behind it. && .AVIATION (12Z TAF Issuance)...
