Commodities Market Impact Weather

MINNEAPOLIS (DTN) -- Two active jet streams fighting for control in the U.S., scattered showers in Brazil and recent heavy rain in Argentina are the weather factors driving the markets Tuesday.

CLIPPER SYSTEMS SETTING UP FOR MIDWEST

A clipper will move through the Midwest Wednesday and Thursday, bringing more scattered showers and some cooler air. Another will follow quickly for Friday which may have some streaks of heavier precipitation. Bands of moderate to heavy snow will be a threat with both. Several more clippers will move through next week and temperatures could vary significantly from day to day as systems come and go.

LIMITED SHOWERS IN CENTRAL AND SOUTHERN PLAINS

A clipper will move off to the north on Wednesday and could bring some showers to northern areas of the Central Plains. Another will move through the region on Thursday and Friday. That one may tap into more moisture and bring a few more streaks of showers, which may include some moderate snow. Clippers are likely to move through the area next week as well. Temperatures could vary wildly between these systems.

CLIPPERS, PERIODS OF LIGHT SNOW FOR NORTHERN PLAINS

Several small systems will move through the Northern Plains over the next couple of weeks. They may not bring much precipitation, though some streaks of heavier snow will be possible. But they will also tend to bring down some cooler air starting on Wednesday.

HEAVY RAIN FELL IN DELTA

Heavy rain went through the Delta over recent days, which continues to ease drought conditions and flooding has been more significant recently. Another system will come through on Friday and Saturday with more potential for rain.

VARIABLE SHOWERS IN BRAZIL

Scattered showers across central Brazil have become isolated. A front moving north from Argentina will bring heavier rain to southern and eastern areas for the rest of this week. The south has been too dry for several weeks and needs the rain. By the weekend, showers are forecast to be widespread and heavy for much of the country, beneficial for everything but fieldwork as soybeans are still being harvested and safrinha corn is still being planted. Southern areas will not be wet for long as it unfavorably gets dry again next week.

RECENT HEAVY RAIN IN ARGENTINA

Heavy rain returned to Argentina last week through early this week and put an end to the hot and dry conditions that caused corn and soybeans to suffer from mid-January. Soil moisture has increased and crop conditions have stabilized. Another system is forecast to move into the country this weekend.

VARIABLE RAINFALL IN EUROPE

Scattered showers went through most of Europe over the weekend, including southern areas that have been dry. The main storm track will be farther north for most of this week, though some showers may go through Spain on Thursday and southeastern areas and Italy this weekend. While crops are vulnerable to winterkill with no significant snow cover, there are no risks of arctic freeze.
