在平原地区，由于西北风强劲且燃料极度干燥，德克萨斯州及邻近州份的野火威胁依然存在。此外，南部高平原在5天内经历了第二次重大沙尘暴——3月14日和18日，德克萨斯州拉伯克在这两次事件中分别承受了82和78英里/小时的最大风速。更北部地区，从科罗拉多州东部到内布拉斯加州，一场季末暴风雪正在展开；风速高达70英里/小时的风雪导致旅行中断和牲畜压力。Weather has dramatically changed in many places in the USA, with a high-pressure system bringing dry weather to the west, increased wildfire risks in the plains, a snowstorm hitting the Corn Belt, and warm weather arriving in the south.
The following is the Agriculture weather advisory for the USA on Wednesday, March 19, 2025, exclusively compiled by the Jinshi Futures APP.
West
In the western USA, a high-pressure system across the inland area has led to generally cool and dry weather. The residual snow in the Central Rockies is melting away, while a cold front is approaching the Pacific Northwest. On March 18, southern New Mexico and surrounding areas experienced a severe dust storm, with visibility dropping to less than half a mile.
Plains region
In the plains region, the threat of wildfires remains due to strong northwestern winds and extremely dry fuels in Texas and neighboring states. Additionally, the southern high plains have experienced the second significant dust storm within five days—on March 14 and 18, Lubbock in Texas recorded maximum wind speeds of 82 and 78 miles per hour during these two events respectively. Further north, from eastern Colorado to Nebraska, a late-season snowstorm is unfolding; blizzard conditions with wind speeds reaching 70 miles per hour are causing travel disruptions and stress on livestock.
Corn Belt
In the Corn Belt, rain and thunderstorms west of the Mississippi River are transitioning into wind-driven snow, with blizzard warnings in effect for southeastern Nebraska, northwestern Iowa, and southeastern Minnesota. In areas affected by the blizzard with wind speeds up to 70 miles per hour, livestock producers are preparing for the impact. In stark contrast, the high temperatures in most of the Midwest today will exceed 70 degrees Fahrenheit.
Southern region
In the south, the warm and dry weather near the cold front is favorable for spring field work. However, the cold front will become active later today as it crosses the Mississippi River Valley, potentially triggering thunderstorms. Today's high temperatures will reach or exceed 80 degrees Fahrenheit from southern Texas to the southern Atlantic coast.
Outlook
The low-pressure system currently moving through the western Corn Belt will arrive in the Great Lakes region from the evening of March 19 to the morning of March 20. Winds and snow associated with this system will end tonight in the central plains and upper Midwest, and will conclude on March 20 in the upper Great Lakes region. The follow-up cold front of the storm will become active, with localized severe thunderstorms expected to erupt later today in the central and lower Mississippi River Valley and sweep eastward towards the central and southern Atlantic coast on March 20. In the northeast, rain and snow will continue until March 21. Subsequently, a pair of disturbances from The Pacific will move quickly eastward, producing light precipitation mainly in the northern part of the USA. In the southern regions, dry weather will continue in the southwestern USA over the next five days, with an elevated risk of wildfires in the southern high plains.
The March 24 to 28 outlook from the National Weather Service for the USA indicates that much of the region east of the Mississippi River may experience near or below normal temperatures, while warmer weather above normal will occur from the Pacific coast to the plains. Meanwhile, precipitation amounts across much of the USA are near or below normal levels, contrasting with above-normal precipitation in the "marginal" areas, including the northeast, much of the coastal regions from southern Texas to Florida, and areas from the Pacific Northwest to North Dakota.
