According to one embodiment, a weather radar apparatus includes an antenna apparatus, a signal processing apparatus, a data converter, a forecasting unit, a state determination unit, and radar controller. The antenna apparatus radiates a radar pulse and receives a reflection pulse. The signal processing apparatus calculates a reception intensity, a Doppler speed, and a speed width. The data converter calculates rainfall intensity data and wind direction/speed data. The forecasting unit generates forecasting data based on the rainfall intensity data and on the wind direction/speed data. The state determination unit generates an observation sequence. The radar controller controls the antenna apparatus in accordance with the observation sequence.
