DTN Ag Weather Brief

METEOROLOGICAL DISCUSSION:

There are troughs in Central Canada and the Gulf of Alaska. A ridge is building over the Eastern U.S. over the next couple of days and will shift westward early next week toward the Rockies, forcing a trough to develop across the East.

EXTENDED OUTLOOK:

The Gulf of Alaska trough should send a piece of energy over the top of the ridge through Canada late next week and weekend, deepening in the East.

The U.S. and European models are similar. I will use a blend, but favor the European.

A front will push through the country early-to-mid next week, producing scattered showers and a drop in temperature. A major hurricane, Erin, is forecast to approach the East Coast in the middle of next week. The front should keep it offshore, but will need to be watched. Another system is forecast to move through late next week and weekend with scattered showers as well as another drop in temperature.

NATIONAL TEMPERATURE/RAINFALL EXTREMES:

HIGH THU...116 AT 16 MILES SOUTHWEST OF TECOPA, CA

LOW THU...33 AT KLAMATH MARSH, OR

24-HOUR PRECIPITATION ENDING AT 7PM CDT THURSDAY...ATLANTIC CITY, NJ 1.63 INCHES

MAJOR WORLD HIGHLIGHTS/IMPACT:

NORTHERN PLAINS (LIVESTOCK/WHEAT/CORN/SOYBEANS): A front stalling in the region will bring sporadic showers through the weekend. The front should completely move out early next week. Another front should move through late next week with more showers. The rain is favorable for filling corn and soybeans, but could continue to negatively impact wheat quality and harvest. Severe weather is also possible with the fronts.

CENTRAL/SOUTHERN PLAINS (LIVESTOCK/CORN/SOYBEANS): Sporadic showers may develop over the next few days before a front moves into northern areas on Sunday and Monday. Temperatures will be hot and stressful to some areas that are still on the drier side. The front will push through next week, bringing showers and a relief in temperature.

MIDWEST (LIVESTOCK/WINTER WHEAT/CORN/SOYBEANS): Temperatures are rising going into the weekend and could be stressful for some areas that have been a bit too dry in the east. Another front will is moving into northern areas and will stall through the weekend before moving southeastward next week. Some areas of flooding around Minnesota and Wisconsin are going to be possible as well as severe weather and temperatures will fall behind the front. Other areas should get chances for at least moderate rainfall, helping with filling corn and soybeans where they hit. However, some areas are likely to get missed and could compound some of the dryness that has occurred in the east.

DELTA/LOWER MISSISSIPPI RIVER (CORN/SOYBEANS/COTTON/TRANSPORTATION): Isolated showers continue in the region into next week, especially across the south. Dry spots are popping up in the region and the rainfall will be important to finish out the crop. Many areas are getting missed, which could hurt the latter stages of corn and soybean fill, as well as cotton.

PACIFIC NORTHWEST (WHEAT): Dry conditions and rising temperatures continue to bring spring wheat closer to maturity as harvest starts to rapidly increase and winter wheat finishes up. Only limited chances for rain are in the forecast this weekend to slow down that progress.

CANADIAN PRAIRIES (WHEAT/CANOLA): Areas of heavy rain over the last ten days have been favorable for later-developing crops, but have been a negative factor for maturing and early harvest in other areas. Those across the north and east have seen beneficial rainfall to reduce drought and could make for another cutting of hay as we see more rainfall chances through this weekend and next week. That could set back harvest and quality some more, but it should also help to battle the wildfires across the north.

BRAZIL (CORN/WINTER WHEAT): Recent frost across the south may have had some impact on early-developing wheat in a few spots, but overall should not have been all that damaging. Spring planting will begin in about a month as long as soil moisture is favorable across the south. It will be drier through the weekend, but we could see another front move in next week with showers across the south.

ARGENTINA (WINTER WHEAT): A front should bring another round of colder temperatures this weekend, which may produce some frosts. Wheat should still be vegetative and not be all that impacted from the cold, but will be heading later this month and is in need of some rainfall. A front that goes through next week is more likely to spread beneficial rainfall through the country, but also a drop in temperatures that could also produce more frosts. With wheat a little more advanced than this past weekend, it could start to become a little more damaging.

EUROPE (WINTER WHEAT/CORN): Hotter and drier conditions continue in most places through the weekend, though a front moving through may produce some limited showers in a few lucky areas in the northeast over the next couple of days. The hot and dry conditions are putting stress on filling corn, but is favorable for the remaining wheat harvest. A more widespread rain event and drop in temperature is forecast for next week with a system rolling through most of the continent.

BLACK SEA (WINTER WHEAT/CORN): It continues to be very dry for much of the region. A weak system could bring limited showers through this weekend into next week, but coverage is forecast to be awfully low. More reports of drought stress continue to pop up on social media as harvest continues for wheat and corn continues to fill. Good weather has come in short bursts this season, with stress due to heat and dryness more common than not.

AUSTRALIA (WINTER WHEAT/CANOLA): Western Australia has seen a good trend of increasing rainfall over the last few weeks while fronts have been struggling to produce rain in the east. That appears to be true with a couple of fronts next week and weekend as well. Though wheat conditions are improving in the west, they've been more stagnant and fair in the east. Wheat and canola in the southeast should start to get into their reproductive stages soon and could use some more rain in which to do so.

CHINA (CORN/SOYBEANS): A front will continue showers in portions of central China for the next few days and another disturbance is forecast for the weekend with some more favorable rain chances for filling corn and soybeans. Central China has endured more instances of heat and dryness than other areas of the country and could really use the rain. Areas in the northeast have had more consistent rainfall and variable temperatures, with largely favorable weather for corn and soybeans there.
