This radar has good visibility in all directions with light echoes being detected out to about 100km and stronger echoes out to about 300km. Light rain from mid-level cloud can be "seen" out to about 250km, however, these can sometimes be misleading as the radar often detects virga (precipitation which does not reach the ground).
Mackay forecast: Saturday
Sunny. Light winds becoming S/SE 15 to 20 km/h in the morning then becoming light in the early afternoon. Overnight temperatures falling to between 10 and 15 with daytime temperatures reaching the mid to high 20s.
