Official National Weather Service forecast for the nearest NWS forecast point.
United States coverage: your search or coordinates are sent to the weather services (open-meteo geocoding and weather.gov) only to look up the nearest forecast point — no location is stored. "Use my location" sends your device's latitude and longitude to weather.gov for the same purpose. Data: National Weather Service (NOAA). Source: National Weather Service forecast, hourly data, and active alerts.

Worked example: how a range bar is placed
Take a week of NWS periods in deg F: Mon 72/54, Tue 68/50, Wed 61/47, Thu 58/44, Fri 66/49, Sat 74/55, Sun 77/58. Each day collapses to two numbers, the higher and the lower of its day and night values. The weekly scale uses only the higher numbers: 77 on Sunday down to 58 on Thursday, a span of 77 - 58 = 19 degrees, floored at 2.
Thursday's bar: left = (44 - 58) / 19 x 100 = -73.7 percent, width = (58 - 44) / 19 x 100 = 73.7 percent, with a 1 percent floor on width. Sunday: left = (58 - 58) / 19 x 100 = 0.0 percent, width = (77 - 58) / 19 x 100 = 100.0 percent. Thursday's low of 44 sits below the scale floor of 58, so its bar starts at a negative coordinate: the scale is anchored to highs, not to the coldest reading.
Limits and boundary cases
Geocoding returns the single best match for a typed search, so a name shared by several states can resolve to the wrong one; the dropdown offers 5 candidates instead. The label under the temperature is not your search text: it comes from the NWS forecast point's nearest relative location, often a neighboring town. Searches outside the United States end in the error panel, because api.weather.gov/points answers 404 for any coordinate beyond US coverage.
Every temperature is rounded with Math.round: 72.4 deg F shows 72, 72.5 shows 73, and the hourly strip stops at 24 slots no matter the data length. Humidity falls back to a dash when the hourly payload omits it. Only the first active alert appears in the card while the count tile totals all of them. The 0 to 100 percent chance of precipitation the NWS returns is never displayed; the umbrella line comes from keyword matching on the forecast wording, so phrasing drives the advice, not the numbers.
