At the time of screen capture, clouds were present over the eastern surrounding area of the city with clear skies in the western and central regions of the city.  Warm low level warm clouds resided over much of the area with a very cold high level system to the north moving southwards.  Radar revealed no precipitation.  The feature on Wunderground.com may have not been working properly as I was not able to see any precipitation at various zoom levels.  Zooming in on the locale, one can see the city sits in a high basin beside a man-made lake. Dendritic streams flow from the surround mountainous region into several dammed lakes. The area's vegetation is abundant including in and around urban centers.

Above we can see the stationary front associated with the low pressure system in the Atlantic.  With High pressure moving on the western side of the cool air and warm air coming in from the north, Brasilia is getting some precipitation today.  The forecast called for 80% chance of rain.  This front should move south and east as the low pressure system is pushed to the south by the two High pressure systems to the west and east.
