Tempest News, March 2026 | North America

"It was one of those March days when the sun shines hot and the wind blows cold: when it is summer in the light, and winter in the shade."
-  Charles Dickens

February Weather Summary

February delivered a little bit of everything across North America, from springlike warmth in unexpected places to powerful storm systems that brought heavy rain, snow, and sharp temperature swings across the continent. Repeated storm tracks across the Midwest and Northeast fueled dramatic week-to-week contrasts, highlighting just how active the late-winter pattern became as seasonal boundaries really began to shift.

Across the WeatherFlow-Tempest Network, thousands of stations captured those extremes in real time, documenting data like just how wide February’s temperature spread truly was from coast to coast.

The highest temperature reported across the Tempest Network in February reached 105°F in Laredo, TX.

The lowest temperature observed on the Tempest Network dropped to a frigid -28°F in Ray, MN. 

Data Look Back: Rapid Pressure Changes, Real Network Impacts

One of February's most compelling network visuals came from the rapid sea-level pressure changes recorded as a strong East Coast storm intensified late in the month. The 3-hour pressure change timelapse clearly shows the corridor of falling pressure sweeping across Tempest stations, a signal of a deepening system and a powerful way to visualize storm evolution in real time.

What makes this even more notable is how network data carried beyond the just the sea level pressure visual. Storm reports issued by the National Weather Service Boston and the National Weather Service New York heavily cited WeatherFlow ProNet station wind observations during the event, highlighting the operational value of dense, ground-level observations when it matters most. Several other outlets also cited ProNet data when reporting on the storm, many including the top wind gust measured of 77 mph in Wellfleet, MA. 

This Month in Weather History

Nearly a century ago, the deadliest tornado in U.S. history tore across Missouri, Illinois, and Indiana during what became known as the Tri-State Tornado.

The tornado traveled an astonishing 219 miles, remained on the ground for over three hours, and reached estimated speeds near 70 mph, devastating entire towns along its path. With 695 fatalities, it remains the single deadliest tornado ever recorded in the United States and helped shape modern tornado research, warning systems, and severe weather preparedness.

Tempest in the Elements

Tempest in the Elements looks a bit different this month… meet Mando! He belongs to Scott and Tracy, and he’s sitting on a temperature blanket made by Tracy using the Tempest temperature reading every day of 2025. Each color row represents a different temperature range, coming together to create a physical record of the year’s daily high temperature. Thanks, Scott and Tracy, for sharing this creative project with us! Want your setup or project to be featured?

Tempest Feature: Packaging Sustainability Spotlight

For us at WeatherFlow-Tempest, innovation isn’t just about better weather data - it’s about better environmental impact, too. That’s why we’re proud to partner with Cruz Foam to rethink how our products are packaged. Together, we’re moving away from traditional foam and toward sustainable materials that reduce waste and better align with our vision and product.

In a recent Q&A, our co-founder and CTO David St. John dives into how this collaboration works and why redesigning packaging to be more environmentally responsible matters...not just for us, but for the communities and landscapes where Tempest systems live and operate. Read More >>>

The 2026 Winter Olympic Games Were "Slushy"

Conditions at the 2026 Winter Olympic Games in Milan showed how warmer, wetter ice and snow can change the playing field for skiing and skating. Athletes experienced slushier surfaces than in traditional competitions, highlighting how shorter, milder winters are already affecting performance and preparation for elite competitors. This shift isn’t just an Olympic curiosity, it also reflects broader climate trends that may reshape winter weather norms and how communities (and events of global scale) adapt to them.

March Gardening Checklist

As temperatures begin to rise and daylight increases, March brings a host of opportunities for gardeners preparing for spring growth. Now’s the time to clear winter debris, cut back old growth, divide and plant perennials, sow hardy seeds, and get bare-root roses in the ground before they break dormancy. Tackling these jobs now can set up a vibrant, productive growing season once warmer weather fully arrives. Read More >>>
