539 FXUS63 KIND 011756 AFDIND Area Forecast Discussion National Weather Service Indianapolis IN 156 PM EDT Mon Jun 1 2026 .KEY MESSAGES... - Skies gradually clearing tonight - Dry weather through Friday with seasonable temperatures - Next chance for widespread rain will be late Saturday into Sunday && .DISCUSSION (This evening through Monday)... Issued at 155 PM EDT Mon Jun 1 2026 Overview. A tranquil and pleasant start to meteorological summer is underway across central Indiana. The primary takeaway for the week ahead is a prolonged period of dry, comfortable weather with near-average temperatures before widespread rain chances return by the upcoming weekend. A mix of sun and clouds will give way to completely clear skies by tomorrow as high pressure positioned north of the Great Lakes maintains firm control of the regional weather pattern. Tonight through Tuesday. As a weak upper-level trough exits the region this evening, any lingering mid-level cloud cover will dissipate during the overnight, giving way to clear skies and quiet conditions towards Tuesday morning. Latest model guidance shows strong atmospheric ridging expanding from the central Plains into western Ontario in the aftermath of the exiting system. This setup will induce subsidence across Indiana, effectively suppressing cloud development and keeping the column incredibly dry. At the surface, the strong high pressure system situated to our north will continue to advect cool and dry easterly flow into the area. Excellent radiational cooling tonight will allow overnight low temperatures to comfortably drop into the lower to mid-50s. On Tuesday, ample solar insolation will easily counter the cool easterly breeze, bringing afternoon maximum highs to near-seasonal normals in the upper 70s. Wednesday through Monday. The extended forecast period features a gradual transition from a highly stable regime to a warmer and eventually unsettled pattern. Dry and sunny conditions will persist through Wednesday as the primary ridge axis shifts overhead, pushing afternoon high temperatures into the lower 80s. By Thursday and Friday, global model ensembles indicate that the upper-level ridging will begin to break down, shifting to a more west-to-east, or zonal, flow aloft. Concurrently, surface high pressure will slide to the southeastern United States, establishing a southerly return flow that will bring a warmer and humid airmass into the Ohio Valley. While a weak frontal boundary will approach central Indiana from the northwest on Friday afternoon, forecast soundings indicate that precipitation chances remain very low. Strong mid-level capping and an atmospheric temperature inversion will limit available CAPE, keeping conditions mostly dry through Friday evening. The next opportunity for widespread rainfall and impactful weather arrives on Saturday. Global models continue to struggle with the broader synoptic pattern with differences on how quickly the aforementioned ridge will break down which bring significant uncertainty to the overall forecast. Generally trended the forecast towards a drier solution for Saturday with models likely tampering down the ridge a bit too soon without a strong system behind it. This keeps rain chances fairly low until late Saturday night into early next week. && .AVIATION (18Z TAF Issuance)... Issued at 155 PM EDT Mon Jun 1 2026 Impacts: - Northeasterly gusts up to 20kts after 15Z Tuesday Discussion: VFR conditions expected through the TAF period with skies gradually clearing through the late evening into the overnight. Skies should be clear by 12Z tomorrow. Winds will generally remain easterly to northeasterly at 6-10kts through tonight before gusts up to 20kts become more frequent after 15Z tomorrow. && .IND WATCHES/WARNINGS/ADVISORIES...
