Daily Weather in Brasilia

My country's capital city is Brazilia. My forecast will cover March 20th-24th. The first day high is 86 and the low is 66 with a 20% chance of precipitation. The second day high is 84 and the low is 66 with a 90% chance of precipitation. The third day high is 83 with a low of 66 and a 90% chance of precipitation. The fourth day has a high of 83 with a low of 66 and an 80% chance of precipitation. The fifth and final day has a high of 78 and a low of 65 with an 80% chance of precipitation. The current weather radar shows lots of clouds over Brasilia. The colors are mainly blue and yellow which means mainly high cold clouds. The local terrain can't be seen because of the current heavy cloud cover.
The zoomed out map of South America shows a lot going on. First thing that catches my eye is 2 H pressure systems and 2 L pressure systems. There are also numerous warm and cold fronts approaching South America.The highest pressure is 1028 mb, and the lowest can't be seen because the numbers are covered by the letters.
The more zoomed in map of Brazil shows a lot less going on. There is a low pressure system south of brazil. The highest pressure I can read is 1012 mb. The only front I can see is a stationary front to the SE.

Global and Local Winds in Brazil

The latitude and longitude of Brazil are: 10.6500° S, 52.9500° W. It's located in the Southern Hemisphere in the Hadley Cell. It's located in the trade wind belt with the prevailing wind direction being SE trades. It's located near the equatorial low pressure belt. It's also located near the doldrums. I speculate that because it's located in the Hadley cell near the doldrums, the climate is humid and the trades aren't as strong in the northern end of the country that's closer to the equator. The southern end of the country probably has a less humid climate because of the prevailing SE trades. The trades also make day to day weather change more, similar to Hawaii. Brazil has some small mountains in the center, but nothing major like neighboring country Chile. 5 breezes or winds associated with mountains are: mountain breeze, chinook winds, santa ana winds, katabatic winds, and valley breezes. Brazil can experience mountain and valley breezes, as well as katabatic winds. Brazil does have coastline. Two winds associated with coasts are land breezes and sea breezes. Yes, Brazil can experience both land and sea breezes.
