Forecasts come from the National Weather Service's own computer models, and current conditions from the nearest reporting weather station. Both are served through the weather API. A forecast is guidance, not a warning, and anything the Weather Service has actually issued is on the live map.

The written summaries on this page are generated from the forecast data above, not by a meteorologist. Each sentence is a reading of the same numbers you can see, and no forecaster has reviewed them.

Place data from the US Census Bureau. Coordinates are the Census internal point for Compton, and the forecast is for that location, not for every address inside the city limits, and a large city can have real weather differences from one side to the other.

How well can the network see Compton?

The nearest Doppler radar is KSOX (Santa Ana Mountains, CA), 34 miles to the E. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Compton its center is about 2,200 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Compton to show rotation in the part of a storm where tornadoes actually form. Compton is closer to its radar than 64% of US cities.

The closest instrument actually measuring the air is KHHR · Hawthorne Muni on the ASOS/AWOS network, 6.4 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.

Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the California observing network as of this build.
