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 Monday.

CLIPPER SYSTEMS SETTING UP FOR MIDWEST

A band of showers and thunderstorms went across the southern end of the Midwest over the weekend and another storm is going to bring more showers to the south Monday into early Tuesday. It may be just cold enough for some snow in some sections. A clipper will move through Wednesday and Thursday and bring more scattered showers but also some colder air. Clippers will be common then through next week and temperatures could vary significantly from day to day as systems come and go.

LIMITED SHOWERS AFTER HEAVY SNOW IN CENTRAL AND SOUTHERN PLAINS

A system developed over the weekend and brought some moderate to heavy snow across the southwestern Plains. Precipitation ends early Monday. A clipper will move off to the north on Wednesday and could bring some showers to northern areas. Another could do something similar on Thursday and Friday. But that one may be able to tap into more moisture from the south going into the weekend. Clippers are likely to move through the area next week as well. Temperatures could vary wildly between these systems.

PERIODS OF LIGHT SNOW FOR NORTHERN PLAINS

Some isolated snow showers flew around the Northern Plains over the weekend, but most areas stayed dry. Several small systems will move through over the next couple of weeks. They may not bring much precipitation, though some streaks of heavier snow will be possible. They will also tend to bring down some colder air starting on Wednesday.

HEAVY RAIN FELL IN DELTA

Heavy rain and thunderstorms went through the Delta over the weekend and continued in northern areas on Monday, which includes some accumulating snow. The heavy rain 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 continued across central Brazil over the weekend while being very isolated across the south. This week that will flip as showers become isolated in central Brazil and fronts moving north from Argentina bring heavier rain to southern areas. 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 harvest 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 fell in Argentina last week and continued over the weekend as well, putting an end to the hot and dry conditions that caused corn and soybeans to suffer from mid-January. Another front will move through Monday into Tuesday with another round of widespread heavy rain. Another system is forecast to move into the country this weekend, keeping the moisture coming that could turn conditions back around and make them favorable again.

RAIN MOVING NORTH THROUGH EUROPE

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