Severe Weather: There was a slight uptick in tornado and hail events last week but a big jump in wind reports, nearly doubling the 2025 total thus far. Damaging winds blew across the Central states and eventually into the East by the latter half of last week. In fact, the Dallas-Forth Worth International airport saw flight delays and cancellations as winds of 75mph battered the airport on Tuesday accompanied by a dust storm making for treacherous conditions there. Reports of damaging winds for 2025 thus far nearly doubled from the week prior to almost 1,000 across the nation.
Last week (2-8 Mar) across the World: Much colder trends in eastern North America while the Northwestern U.S. and western Canada were much warmer than last year. The U.S. as a whole trended the coldest in 4 years for the first full week of March. A brief spell of a couple milder days in the Northeast gave way to some colder weather towards the end of the week behind a storm system that brought a soaking rain and strong winds mid-week. A strong storm brought blizzard conditions across portions of the Plains and into the Upper Midwest and northern Great Lakes mid-week.
The mountains of the West added to their snowfall total for the season as a Pacific storm rolled onshore in the second half of the week bringing widespread valley rain and mountain snow across California, the Great basin, and the Intermountain West.
Trending warmer in Europe and drier which was helpful to get consumers into the spring mindset. In South America, hotter in Argentina and southern Brazil, while portions of central and northern Brazil trended colder than last year.
This Week (9-15 Mar): After another relatively cold weekend in the Northeast, temperatures will be on the rebound as we see some of the warmest air since autumn across parts of the central and eastern US. Unsettled weather in the Southeast to start the week with isolated flash flooding in northern Florida and southern Georgia.
Another Pacific storm moves onshore in the West around midweek. That system will head eastward bringing the threat of more mountain snow and perhaps blizzard conditions to the northern Plains late this week as colder air returns. This upcoming weekend we'll need to watch the potential for severe storms in the Mississippi and Tennessee Valleys.
The 6-day snowfall outlook (10-15 March) shows snow mainly for the mountains of the West and northern Plains with the expected blizzard later this week. Interior New England could also see some light snow but nothing significant. Overall, national snowfall is up 48% versus last year with 29% of the U.S. getting some snow.
Next week (16-22 March) trends the warmest in 3 years and 6th warmest of the past 40 years. Snowfall will be down compared to both last year and average while rainfall will be the most in 3 years. Warmer trends in the East and South will be favorable for spring merchandise while colder and wetter weather in the West will be unfavorable.
The World 2-week outlook (09-22 March) shows the colder temperatures remaining in the West while the eastern U.S. gets a taste of Spring. After a brief spell of warmer Spring weather in the United Kingdom, temperatures will take a colder turn towards the latter half of this period, perhaps related to a disruption in the polar vortex. Meanwhile, warmth will be bottled up over the Middle East.
World 2-week Precipitation (9-22 March) shows more wet weather expected for both the West and East Coasts of the U.S. We'll need to watch the Southeast U.S. for increased severe weather threat as the Spring-time clash of air masses fuels instability, which is typical for this time of year.
