CHICAGO, Nov 21 (Reuters) - U.S. soybean futures found support on Tuesday as Brazil's torrid, crop-threatening weather conditions remained a prime worry for the market, despite rains over the last couple of days.

Chicago Board of Trade wheat also rose, while corn was nearly flat.

The most-active soybean contract on the Chicago Board of Trade (CBOT) was up 0.15% at $13.69-1/4 a bushel at 11:10 a. CST (1710 GMT).

Rain during the last few days in Brazil, the top global soybean exporter, was not nearly enough to abate market worries regarding the potential that the long-term brutally hot weather will menace crops, analysts said.

"December could be a tough month again. We could go back to hot dry," said Ted Seifried, chief market strategist for Zaner Ag Hedge.

"Long-term forecasts can be tough to trust. But the concern is that they go back to hot and dry after this week."

Brazil's 2023/24 soybean planting had reached 68% of the expected area as of Thursday, the slowest progress for the period since 2019/20, agribusiness consultancy AgRural said.

The soybean market was also still reacting to the Sunday's presidential election in Argentina, the world's top soymeal and soyoil exporter. Producers may be taking a wait-and-see approach to how the country's President-elect Javier Milei will implement his libertarian agenda after he takes office on Dec. 10, analysts said.

"That likely means that Argentinian farmers aren't going to sell any sort of grain between now and that time. Short term, that's pretty bullish," Seifried said.

CBOT corn was down 1/2 cent to $4.69 and CBOT wheat was up 1.27% at $5.77-3/4 a bushel.

Wheat traders were watching to see if a recent decline in prices, fuelled by global export competition, will stir sizeable new demand after Tunisia and Jordan called import tenders for this week.
