1.4.2 - Major weather overhaul

This release replaces the much older build previously published here. These notes cover the full overhaul now reaching CurseForge and Modrinth, including the work completed across the intermediate development versions.

Weather and tornadoes

• Rebuilt the weather system around persistent clouds and developing thunderstorms, supercells, tornadoes and dissipation.
• Added volumetric fair-weather clouds, gradual storm organization and funnel descent, rotating cloud bases, anvils, local rain and lightning.
• Added cone, wedge, rope, stovepipe and drill funnels, varying width and strength, smaller vortices in strong storms, and up to three tornado cycles from one parent storm.
• Improved overlapping weather volumes, lighting, transparency and temporal smoothing, with quality presets and configurable cloud range/count.
• Fixed terrain motion: hills and valleys stretch only the lower funnel, keeping the upper funnel and cloud anchored. Surface contact changes smoothly and filters small isolated obstacles.

Storm chasing and survival

• Added the craftable Storm Radar with rain, Doppler and hail views, observed tracks, storm selection, range controls, wind corridors and a warning while held.
• Added the craftable Weather Probe with current and peak wind, modeled pressure, rain/hail readings and comparator output.
• Reworked the Tornado Detector with graded lights, sirens, forecasts and distinct comparator warning levels.
• Added shelter-aware wind, material-sensitive destruction, roof/canopy damage, precipitation outflow and hail injury. Roofs, including glass, block rain and hail.
• Added configurable survival, natural-only and visual-only destruction modes. Terrain damage respects mobGriefing and protects inventories, block entities, fluids and essential blocks.
• Bounded terrain checks, removals, entity work and debris across storms; avoided unloaded-chunk terrain access.

Fresh sound set

• Replaced all 22 custom sound files with fresh ElevenLabs wind, tornado roar, rain, thunder and warning-siren takes, plus matching indoor and legacy variants.
• Smooth looping ambience, muffled indoor wind/rain and rain subtitles. Existing volume controls and delayed thunder remain available.

Commands and multiplayer

• Added storm status, inspection and forecasts, explicit funnel-shape demos, bounded outbreaks and removal by storm ID.
• Storms form gradually when commanded and can develop from an existing cloud or eligible storm.
• Synchronized weather and instrument settings between server and clients; saved storm progression; respected tick freeze/step.

Before updating

Minecraft Java 1.21.1 / NeoForge 21.1.250+ for 1.21.1 / Java 21. Remove the old tornado JAR and install 1.4.2 on both the server and every client.

Back up your world. Destruction is enabled by default. Test a copy when moving from the old public build; migration from that older mod has not been verified. Use Fast or Fancy graphics. Fabulous and external shader packs are outside this release's support scope.
