FXUS63 KIND 200732 AFDIND Area Forecast Discussion National Weather Service Indianapolis IN 332 AM EDT Wed May 20 2026 .KEY MESSAGES... - A Flood Watch remains in effect until 2pm today across south central Indiana - Cooler mid week with a brief break from rain chances, before showers and storms return to the forecast late week into the holiday weekend && .DISCUSSION (Today through Tuesday)... Issued at 332 AM EDT Wed May 20 2026 Today - Precip along the cold front slowed southward progress this evening, but the boundary will continue to slowly sag through the region today. Upper level waves moving along the front will produce additional showers and a few thunderstorms today, primarily across the southeastern half of the area, and mainly through mid afternoon before rain chances rapidly taper off across the area. Will maintain the flood watch in place across the south given this expectation and continued plentiful deep moisture through midday. Relatively minimal instability will limit coverage and intensity of thunderstorms, with no severe weather expected. Tonight through Tuesday - High pressure will produce cooler conditions through much of the rest of the work week, with rain chances returning as a broad upper level low and associated shortwave disturbances pull a warmer and moist airmass back into the region. Model agreement is fairly high on what may end up being a washout on Friday, though discrepancies increase quite a bit beyond then. Blend PoPs have increased in the past 24 hours for the holiday weekend, though there is significant uncertainty in coverage at any one time, and changes are likely in the coming days. Nonetheless, rain chances and above normal temperatures will characterize the coming holiday weekend into early next week. && .AVIATION (06Z TAF Issuance)... Issued at 119 AM EDT Wed May 20 2026 Impacts: - Showers and a few thunderstorms, primarily from HUF/IND southeastward - Ceilings likely to deteriorate to MVFR, with IFR at BMG Discussion: A cold front has temporarily stalled over the area and is producing additional showers and a few thunderstorms across the southeastern half of the area tonight. This will continue much of the overnight and additional showers will be possible during the day on Wednesday. Trapped low level moisture along and north of the boundary as it slowly pushes southward will cause ceilings to deteriorate overnight, falling to MVFR at least briefly at all sites later this morning. BMG will likely drop into IFR at least briefly, but MVFR may predominate at all sites except LAF much of the period. Winds will generally be north/northwesterly early, but gradually become northerly then northeasterly with time. && .IND WATCHES/WARNINGS/ADVISORIES...
