Weather Academy & Glossary

A weather school that
lives inside the forecast.

Most apps assume you already know what a dew point is, or assume you never will. Sensecast takes a third position: every number on the screen can explain itself, at whatever depth you want, the moment you are curious. Then it gets out of the way.

How an explanation is built

Analogy first. Physics last.

Tap the information button on any metric and a sheet opens with the same three layers every time. You can stop after the first one and still have learned something true.

The Dew Point Temperature explanation sheet, showing an everyday sensation analogy, a five-band sensation and safety scale from crisp under 55°F to tropical rainforest mugginess above 70°F, and a collapsed atmospheric physics section.

Dew point, as the app explains it

The analogy sits at the top where it cannot be missed, the banded scale gives the reading somewhere to stand, and the physics stays collapsed until you ask for it. The three cards below take that sheet apart.

Layer one

Everyday sensation analogy

What this number feels like on skin, in a sentence, with no jargon and no equation.

“The absolute measure of mugginess. Dew point tells you the exact temperature to which air must cool for moisture to condense into dew or fog.”

Layer two

Sensation & safety scale

Where today's reading sits on a banded scale, so the number has somewhere to stand.

Layer three

Atmospheric physics & equations

An expandable section with the real mechanism — for when the analogy is not enough.

“Rapid barometric drops (≥ 3 hPa in 3h) alter the pressure differential in sinus cavities and inner-ear chambers, triggering migraines, vascular dilation, and arthritic joint inflammation.”

The catalogue

Twenty-seven topics,
four categories, one search box.

The Academy is a screen of its own, not just a set of tooltips. Search atmospheric terms, models and physics, or filter by category and read straight through.

The Weather Academy and Glossary screen with a search field, category filter chips, and entries for Feels Like, Relative Humidity, Dew Point Temperature, Barometric Pressure and Solar UV Radiation Index.

The real screen

Search runs over terms, models and physics at once. The chips filter to a category, and every row opens the three-layer sheet.

Below is the same catalogue, filterable here on the page.

In the flow of use

Where the tips show up.

Contextual buttons sit on the cards themselves, so the explanation arrives at the moment the question does. A master switch in settings turns the whole layer off once you no longer need it.

13 condition tiles

Current conditions detail

Dew point, pressure, UV index, wind gusts, POP%, cloud cover and the sun arc each open to real-world physical meanings.

Air & allergens

Air quality and pollen cards

EPA health thresholds, PM2.5 particle-size analogies, and tree, grass and ragweed peak seasons.

Space weather

Aurora and geomagnetism

The Kp scale from 0 to 9, coronal mass ejections, and which latitudes actually get a view tonight.

Radar

Doppler reflectivity

How to read decibels of reflectivity, and what separates a light drizzle echo from a hail signature.

Models

Numerical weather prediction

How ECMWF IFS, NOAA GFS, HRRR, DWD ICON and Canada GEM actually compute fluid dynamics over a grid.

Grid

Power outages and reliability

How storms, ice loading, tree limb contact and grid surges turn into an interruption at your address.

Free, all of it

The academy is not
behind the paywall.

All 27 topics, every tap-to-learn sheet and the full glossary ship with the free app. Learning the atmosphere should not be the upsell.

Built on published science

Explanations draw on the Steadman apparent temperature model, the Rothfusz heat index regression, Rayleigh scattering, EPA AQI breakpoints and NOAA Storm Prediction Center climatology — cited in the app, not paraphrased from a blog.
