Every page, and what you can do on it

Snow cover and depth come from NOAA’s National Snow Analysis, combining observations with a snow model. The map names the analysis time and uses NOAA’s official depth legend.

• Snow depth in inches, with the official NOAA colors
• Latest provider analysis time, not a guessed live timestamp
• Contiguous U.S. coverage; missing data is not labeled snow-free

Start typing a city and the app finds it, pulls the latest conditions, and shows them as a single card. The result is kept in the web address, so a searched city can be bookmarked or sent to someone else and opens exactly as it was left.

• Temperature, conditions, humidity and wind for the city you typed
• Below the card: live temperatures at the largest city in every state, plus NOAA's fronts and pressure positions
• An unknown city gets a clear message instead of a blank page, and a failed lookup gets a Try again button

Each recap is worked out in that city's own time zone, so Honolulu and Anchorage get their own yesterday rather than being dragged onto the mainland calendar. Observations are marked Preliminary until the source finalizes them, and every record lists the station, its historical coverage, and where the number came from.

• Observed high and low next to the 1991–2020 normal for the same day
• Record high, low, rain and snow for that calendar date, with the year each record was set
• A Preliminary or Final badge on every card, plus the station, coverage and source underneath

The Fronts page carries the maps forecasters draw at the Weather Prediction Center, with the current analysis and 12, 24, 36 and 48-hour forecasts side by side. A guide underneath explains how to read each symbol, and the same fronts are drawn as live lines on the app's own maps.

• Cold, warm, stationary and occluded fronts, plus troughs
• High and low pressure centers marked the way forecasters mark them
• A short guide to reading the symbols before you interpret a map

Radar runs as a loop through the most recent frames so you can watch a storm move rather than guess from one still image. Frame times are shown, and the loop can be stepped through by hand.

• Recent frames looped, with each frame's time
• Step through the loop frame by frame instead of watching it run
• Radar can be switched on over the satellite and terrain views used elsewhere in the app

Alerts come from the National Weather Service and only from the National Weather Service. The app never invents an alert, never upgrades one, and never shows an alert that has expired. If the feed is unavailable, the page says so plainly instead of showing an empty list.

• Every active alert with its severity, urgency and the area it covers
• Grouped and searchable by state
• No alerts are ever generated or guessed — an unavailable feed is reported as unavailable

The forecast page is the everyday view for a single place: temperature through the day and night, rain and snow chances, wind, and the days ahead. It opens from a search, from the map, or from a saved location.

• Hourly temperature and precipitation chance
• Daily highs, lows and conditions for the days ahead
• Opens from a city search, a map click, or a saved location

Compare puts the same numbers for several places in one view — temperature, rain, wind and the days ahead — so a decision about travel, moving, or a weekend plan rests on the same figures for each city.

• The same measurements for each city, in one view
• Days ahead shown for every city at once
• Built from the same live figures used everywhere else in the app

The States page lists all fifty with their current conditions, and lets you sort by temperature, rain or wind, or search for a state. Each entry opens that state's own page.

• Sort by warmest, coolest, wettest or windiest
• Search by state name, abbreviation or capital
• Each state opens its own page with detail for the state

The full map is where the layers come together: current temperatures, satellite clouds, rain radar and NOAA's fronts and pressure centers can each be turned on or off, over a dark, satellite or terrain base.

• Temperature, cloud, radar and front layers, switched independently
• Dark, satellite and terrain base maps
• Clicking a state opens that state's page

The dashboard is the desk view — national conditions, saved locations, all fifty states, the hottest and coldest and windiest places right now, a forecast for the place you care about, and the severe alerts currently in force.

• National conditions and the live temperature map
• Saved locations, plus rankings worked out from the live figures
• A forecast for your selected place and the severe alerts in force
