SOUNDLE

Soundle gives you one atmospheric sounding a day. Read it, call the forecast, and see how close you were.

Read the sounding

Each puzzle is a full SHARPpy sounding — the Skew-T Log-P profile, the hodograph, and the derived severe-weather indices all together. The temperature and dew point traces show moisture and instability with height, while the winds and hodograph reveal the shear that organizes storms.

Pick a storm risk level

Choose the SPC-style outlook category that fits — low to high, left to right:
- None
- Tstm
- Mrgl
- Slgt
- Enh
- Mod
- High
3
Pick the hazards

Call every threat the sounding supports — you can select more than one. Your hazard score rewards how well your picks overlap the real hazards, so over-calling threats that aren't there costs you too:
- Rain
- Hail
- Wind
- Tornado
- Snow
Stuck? Reveal a clue

The chart hides the date and location so you can't just look it up. If you're stuck, reveal the date (−20) or the location (−10) — but each clue is deducted from your final score, so use them sparingly.
Submit and compare

Lock in your forecast to reveal the truth, your score out of 100 (risk + hazards, minus any clues you used), and why the atmosphere behaved the way it did. One play per day keeps your streak going.
