It's had been pretty dry in much of South America this year. The maps below are for 30 days, 90 days and 180 days % of average precipitation:

The forecasts below come from the GFS/US model. Decent rains over much of the area over the next 2 weeks.

Looks pretty HOT in Argentina to S.Brazil...........something to be watched.

Thanks Mike. This is what I really want to start learning more about. Nice to see other areas where crops are grown when I had no clue a few months ago.

A lot of that SA soil seems to need a rain every week

I still only get the left 1/2 of any map you post

You are right about the SA soils. They don't hold moisture as well as ours.

 Widespread rains most places of South America...........with Argentina possibly getting dry in week 2. 

Possible heavy snows in parts of the Cornbelt, mainly  Western Belt/Upper Midwest might be bullish at some point for corn the next few days because of unharvested corn in those areas.

Given the Spring weather and smaller crop  and basis levels, its amazing that CZ prices are this low.

Argentina weather forecasts have in fact turned dry...........almost completely dry the next 2 weeks with the exception of the farthest north growing area.

Still tons of rain in Brazil the next week, before far S. Brazil turns dry early in week 2.

I should add that Argentina has had good rains recently and the first week of dryness will features temperatures below it may take awhile for the market to get exited.

If we go another week with this Argentina forecast, I would be surprised if corn and beans can keep dropping.

Argentina weather still looks dry for 2 weeks. Temperatures are not hot, which will take some of the bullishness away.

Argentina is the worlds #2 corn exporter.

On every model run since last night, rain has increased for Argentina after day 10(dry until then). I am LESS bullish on Argentina weather.

Brazil weather has remained ideal with tons of widespread rains over the next 2 weeks. This is especially bearish for beans as Brazil is the worlds biggest exporter of far and away ahead of the US.

Beans are just above HUGE support right now after dropping down there and holding during the day session. The Jan S low was 867.5 earlier today, which is around the same as the September lows. 

Key technical support for #soybeans. #oatt #harvest19

#Argentina: Unseasonable warmth and dryness dominated the region, limiting moisture for emerging to vegetative summer #grains, oilseeds, and #cotton, but hastening drydown and harvesting of winter grains.

More great rains in Brazil the next 2 weeks.

Dry again in Argentina week 1 before rains return.

Continue watching the dry areas in Argentina which have some provinces running 17-50% of normal precipitation over the last 14-days. Production maps breakdown show areas of most concern. $ZS_F $ZC_F


metmike: Decent rain event for Argentina Fri/early Sat, then dry for a week, then rains pick up for week 2.

The fast moving weather system with decent rains is now thru around the southern half of Argentina and will be north of the growing areas by early Saturday.

There was enough rain to help a bit temporarily with dry soils but the next rain maker will not be for over a soils will get drier next week before any serious relief comes in week 2. Week 2 does look pretty wet for Argentina.....right now at least.

They need alot of rain.

Dry for several days in dry Argentina before rain chances increase.

It looks like S.Brazil will be drying out the next 2 weeks which is turning the South American weather a bit bullish for soybeans.

Still looks like that drying pattern for S.Brazil to start the last week of the year in 2019 and into the first week of January 2020.

Not a massive heat ridge with no rain to keep us soaring higher but just below normal  rains and above temps.
