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.

How well can the network see Primera?
The nearest Doppler radar is KBRO (Brownsville, TX), 30 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 Primera its center is about 1,800 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Primera, so low-level rotation and the leading edge of a gust front show up on it. Primera is closer to its radar than 71% of US cities.
The closest instrument actually measuring the air is KHRL · Harlingen/Valley Intl on the ASOS/AWOS network, 6.0 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 Texas observing network as of this build.
