Touch swipe on the content area moves between tabs (left = next, right =
previous), gated to non-radar views so map pan gestures keep working.
Vertical scroll with |dx|<|dy| is untouched; 60px horizontal threshold.
- New src/lib/router.js: parseHash/ viewToHash for the 5 tab views, with a
default fallback for empty/unknown hashes.
- App.svelte: initialize viewMode from location.hash, setView() updates both
state and the URL hash, and a guarded hashchange listener syncs back/forward
and manual URL edits. All tab onclicks route through setView().
- Tests for parse/viewToHash round-trips and fallback. 76 total pass.
- Lightning layer on PrecipitationRadar: toggleable ⚡ button (persisted via
showLightning setting). When on, fetches recent strikes from the planned CORS
relay and renders them as markers that pan/zoom with the slippy map.
- New src/lib/api/lightning.js: fetchLightningStrikes() reads
https://cors.thecookiejar.me/lightning?lat&lon&radiusKm&limit (relay NOT
deployed yet) with an 8s abort timeout and graceful failure - never blocks or
crashes the map, shows an unavailable banner instead. Exports pure
projectStrikeToLayer() for Mercator tile-layer marker projection.
- showLightning setting added to DEFAULT_SETTINGS + app store; toggle persists.
- Tests: fetch URL/parsing/error handling + layer projection. 71 total pass.
Replace the hidden hover-only native title with a dedicated SourceTooltip
component: a small ⓘ badge rendered inline next to Pressure and UV values
(Current + Details views) that reveals a styled tooltip on hover/focus,
so it is obvious the value came from the non-selected source (Open-Meteo)
instead of requiring discovery by hovering the data.
NWS doesn't publish pressure (its pressure series is empty) or a UV index.
When the selected source is NWS, merge current.pressure_msl, current.uv_index
and daily.uv_index_max from Open-Meteo and tag them via data._fallback so the
Current + Details views show a tooltip noting the value came from the
non-selected source (Open-Meteo) instead of showing 0 hPa / --.
NWS text like 'Slight Chance Showers And Thunderstorms' (~17-24%) was mapping
straight to WMO 95 / thunderstorm icon, over-stating a mere chance of storms.
shortForecastToWmo now takes the period's precip probability (plus chance-like
wording) and downgrades low-chance storms to light showers (80) and low-chance
rain to light rain (61), keeping real/severe storms at 95. This also stops the
false thunderstorm alert banner for low-chance days. Today/Monday for Rogers
County now render as showers instead of storms.
- New Settings > Data source toggle (Open-Meteo global / NWS US); NWS
falls back to Open-Meteo when unavailable or outside its coverage.
- src/lib/api/nws.js: /points -> forecast/hourly/grid normalizer producing
the app's shared shape, with realistic air highs (NWS reports 104 for the
day Open-Meteo over-forecasts at 116); heat-index/feels-like falls back to
air temp since NWS returns apparentTemperature as null here.
- NWS requires a User-Agent contact; email is a build-time Vite env
(VITE_NWS_EMAIL), read from gitignored .env.local, never committed.
- Details view now shows which provider served the data.
- Fixes the identical UTC date-parse shift for NWS naive local times.
- Tests (8) + recorded live fixtures for Rogers County, OK.
