Seven-day outlook

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.

How well can the network see Brisbane?
The nearest Doppler radar is KMUX (San Francisco, CA), 45 miles to the SE. 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 Brisbane its center is about 3,100 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Brisbane to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KSFO · San Francisco Intl on the ASOS/AWOS network, 4.0 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
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.
