Interpreting NEXRAD

I just discovered that IRI has made un UPDATE on the expectations of El Nińo effects on South America on http://iri.ucsd.edu/forecast/net_asmt/text/apr98/SAM_AMJ_JAS.html
This site shows the expectations clearly in maps, with accompanying text. The update has been made in April 1998. 

For those without access to (maps on) Internet I just copied the main part of the text re. the expectations.  The IRI is the International Research Institute for Climatic Prediction. On
the same site they give expectations for other world regions as well. 

Expectations for S Am. made by IRI: 

*******  April-June 1998: 

PRECIPITATION: 

During this season the map is dominated by 4 main regions of enhanced probabilities of major precipitation anoma- lies. These include: 

P.A) Slightly enhanced probabilities for below-normal rainfall to continue over much of northern South America. This includes, in particular, the Nordeste and surrounding areas which, also have a perceived risk for experiencing extreme below-normal precipitation (precipitation values reaching values only seen in the driest 15% of years in the observed record). See map. 

P.B) Continuing enhanced probabilities of above-normal rainfall along the tropical Pacific coast of South America extending from Equador through Peru. A highly enhanced risk of extreme above-normal precipitation (precipitation values reaching values only seen in the wettest 15% of years in the observed record) is perceived for this region. See map. 

P.C) Continuing enhanced probabilities for above normal rainfall in parts of central eastern South America, this region also carries a highly enhanced risk for extreme above-normal precipitation. See map. 

P.D) Enhanced probabilities for below-normal rainfall over the south-most part of the continent. 

TEMPERATURE: 

The map is dominated by 3 main regions of enhanced probabilities of temperature anomalies: 

T.A) Highly elevated probabilities for warm conditions over the northern third of South America 

T.B) Slightly enhanced probabilities for near-normal to above-normal temperatures over the central part of the continent. 

T.C) Enhanced probabilities for the warmer than normal temperatures over the southern parts of Argentina and Chile.
 

******** July-September 1998: 

PRECIPITATION: 

The map is dominated by the following regions of enhanced probabilities of major precipitation anomalies: 

P.i) Elevated probabilities for below-normal rainfall over Venezuela and northern Colombia. 

P.ii) Enhanced probabilities for above-normal precipitation over Nordeste and surrounding areas. 

P.iii) Highly elevated probabilities for above-normal rainfall over the Uruguay, Paraguay, south-most parts of Brazil, northern Argentina. 

P.iv) Slight chances for below-normal rainfall over the southern parts of Argentina and Chile. 

TEMPERATURE: 

The map is dominated by the following regions of enhanced probabilities of major temperature anomalies: 

T.i) Continuing enhanced probabilities for warmer than normal temperatures over the northern half of the South America, except for the region of the enhanced probabilities for the near-normal precipitation along the east coast. 

T.ii) Slightly enhanced probabilities for colder temperatures over the Uruguay, Paraguay, south-most parts of Brazil, northern Argentina.
