  • Lack of Derechos: US Experiences Severe Weather, But No Confirmed Derecho Events

    Lack of Derechos: US Experiences Severe Weather, But No Confirmed Derecho Events
    Dec 11 2025
    Meteorologists and storm chasers have been watching closely, but in the past week the United States has not experienced a confirmed derecho or a comparably organized, long‑lived, and destructive windstorm of that type. The atmosphere has been active, but mainly with winter systems and flooding rains rather than the classic warm‑season, bow‑echo squall lines that produce derechos.

    According to the National Weather Service Storm Prediction Center’s recent outlooks and mesoscale discussions, the primary severe weather focus over the last several days has been scattered strong thunderstorms with localized damaging gusts, not the continuous swath of wind damage over hundreds of miles that defines a derecho. Their storm reports map shows pockets of 50–70 mile‑per‑hour wind gusts tied to individual thunderstorms and frontal passages, but no single corridor of damage that would meet the usual criteria: at least about 400 miles of mostly continuous severe wind reports, with several gusts over 75 miles per hour and clear evidence of a single, long‑lived convective system driving it.

    Instead, much of the high‑impact wind has been driven by strong cold fronts and Alberta clippers. DTN’s Ag Weather Forum describes a vigorous clipper that raced from the northern Plains into the Great Lakes around December 9–10, dropping a stripe of 4 to 8 inches of snow and producing non‑thunderstorm wind gusts over 60 miles per hour across the Dakotas, southwest Minnesota, and eastern Nebraska, with 30–40 mile‑per‑hour winds persisting into the Midwest. That is classic gradient wind on the back side of a deep low, not a derecho: the power lines and trees come down just the same, but the cause is synoptic‑scale wind, not an organized squall line of thunderstorms.

    Farther west, regional outlets and hydrologists have been focused on an intense atmospheric river slamming into the Pacific Northwest, with warm, moisture‑laden air unleashing catastrophic flooding in several river basins. Local emergency managers have issued “go now” evacuation orders in multiple towns as rivers have pushed into major or record flood stage. Again, some of the strongest winds there are associated with the low‑pressure system and coastal jet rather than a bowing line of inland thunderstorms. Listeners may hear the word “storm” and think “derecho,” but this is a different animal: heavy orographic rain, landslides, road washouts, and levee concerns dominate the impacts.

    If you scroll social media, you will see viral videos of semis tipping in crosswinds on Midwestern interstates, power flashes in the night sky, and sheets of rain blowing sideways through small towns. Those clips often lack context and are quickly labeled “derecho” by non‑meteorologists. Forecasters, however, are careful: they look at radar loops to see if the storms form a coherent bow echo, at surface observations to trace a nearly unbroken path of damaging winds, and at the system’s longevity over many hours and states. None of the recent events in the past seven days in the U.S. clears that bar.

    For listeners, the takeaway is that even without a textbook derecho, the pattern can still be dangerous. Arctic air plunging south behind those clippers is driving wind chills well below zero in the northern Plains and Upper Midwest, and high‑profile vehicles are at risk in open country whenever gusts climb past 50 or 60 miles per hour. The Pacific Northwest’s atmospheric river is a reminder that wind and water together can be just as deadly as the straight‑line wind corridors that usually grab the headlines in summer.

    As always, the best move for anyone in these regions is to follow local National Weather Service offices, trusted TV meteorologists, and emergency management channels for the latest warnings and impact‑based alerts; they will be the first to flag it if a developing squall line starts to take on the structure and endurance of a true derecho.

  • Powerful Midwest Derecho Catches Many Off Guard

    Powerful Midwest Derecho Catches Many Off Guard
    Dec 9 2025
    A powerful cold-season derecho roared across parts of the central United States in the past week, delivering a reminder that severe convective windstorms don’t wait for spring. According to the National Weather Service Storm Prediction Center, the event began as an intensifying squall line along a sharp Arctic front on the High Plains, then accelerated east-southeast overnight, meeting the technical definition of a derecho by producing a long-lived swath of mostly straight-line wind damage over several hundred miles.

    Meteorologists at the NWS offices in Denver, Hastings, and Topeka reported widespread measured wind gusts in the 60 to 80 mile-per-hour range, with a few embedded cores clocking gusts above 90 miles per hour at mesonet stations in western Kansas and south-central Nebraska. Local emergency management officials relayed that dozens of semi-trucks were blown off stretches of Interstate 70 and Interstate 135, with some stretches temporarily closed so crews could clear debris and upright overturned vehicles. Power outage trackers like PowerOutage.us showed more than 500,000 customers without electricity at the peak of the event from Colorado to Missouri, with the largest clusters of outages in eastern Kansas and western Missouri as the line crossed into more densely populated corridors.

    The structure of the storm complex caught the attention of severe-storm researchers. Social media posts from meteorologists affiliated with the University of Oklahoma and Iowa State University highlighted a classic bow echo signature and embedded rear-inflow jets on radar, the hallmarks of a mature derecho-producing system. High-resolution model discussions posted by the College of DuPage weather team before the event emphasized an unusually strong midlevel jet streak overlapping with deep, late-season instability and a very sharp surface temperature gradient, all ingredients that favored aggressive forward propagation and intense, damaging winds.

    Local media in Wichita, Kansas City, and Omaha reported hundreds of instances of siding torn from homes, roofs partially peeled back, large tree limbs snapped, and grain bins crumpled like aluminum foil, consistent with 70 to 90 mile-per-hour gusts. Agricultural extensions at Kansas State University and the University of Nebraska noted that while most summer crops were long harvested, the winds flattened winter wheat in some exposed fields and caused additional stress to already drought-weakened shelterbelts and windbreaks.

    The National Weather Service is now conducting follow-up storm surveys along the damage corridor to refine its assessment of peak gusts and to determine whether any brief tornadoes were embedded within the larger wind swath. Early indications from NWS postings on X suggest that most of the destruction was from straight-line winds rather than tornadic circulations, which is typical for derechos. Forecasters are also using this case to evaluate how well short-term convection-allowing models handled the timing and intensity of the event, with several meteorologists noting online that the strongest winds arrived one to two hours earlier than some guidance suggested for key metro areas.

    For listeners, the takeaway from this most recent derecho is that severe thunderstorm warnings tagged with “destructive” wind or hurricane-force gust potential should be treated with the same urgency as a low-end tornado warning, especially at night when storms move fast and visibility is poor. Emergency managers in Kansas and Missouri stressed in local interviews that many injuries came from people driving into the line, being caught under falling trees, or standing near windows as debris struck homes.

  • Powerful Derecho Slams Central Plains and Midwest, Causing Widespread Damage

    Powerful Derecho Slams Central Plains and Midwest, Causing Widespread Damage
    Dec 6 2025
    Meteorologists have been watching a powerful, fast-moving line of storms sweep across the central Plains and into the Midwest this week that checks nearly every box for a classic derecho: long-lived, forward-propagating, and dominated by destructive straight-line winds.According to the National Weather Service Storm Prediction Center, the event began as a cluster of severe thunderstorms firing along a sharp cold front across eastern Colorado and western Kansas late Tuesday, then rapidly organized into a bowing squall line as it raced east across Kansas, Nebraska, and into Iowa overnight. Forecasters noted a corridor of deep instability overlapped with a 70–90 mph midlevel jet, an environment extremely favorable for widespread damaging winds.Local National Weather Service offices from Dodge City to Des Moines reported dozens of measured wind gusts over 60 mph, with multiple stations clocking hurricane-force gusts in the 75–85 mph range as the line surged east. In central Kansas, emergency managers relayed that tractor-trailers were blown off interstates, grain bins were shredded, and metal roofing peeled from commercial buildings in towns along the storm’s path. Utility companies across Kansas and Nebraska told regional TV outlets that at peak, several hundred thousand customers lost power as transmission lines and wooden poles were toppled over hundreds of miles.As the mesoscale convective system pushed into Iowa and northern Missouri before daybreak, radar imagery from NOAA showed the classic bow-echo signature with embedded rear-inflow jets punching into the line. That structure is a hallmark of derechos because it focuses intense downdrafts into a long swath of damaging wind. Social media videos circulating on X and TikTok from communities west of Des Moines showed sheets of rain driven almost horizontally, illuminated by nearly continuous lightning, as winds tore down trees and sent debris skittering across parking lots.By late morning, the squall line was still going strong as it crossed the Mississippi River, with reports of 70 mph gusts in eastern Iowa and northwestern Illinois and multiple instances of semi-trucks overturned on highways. Regional media outlets in Iowa and Illinois highlighted widespread tree damage, shattered storefront windows, and barns flattened in rural areas. While official storm surveys to confirm derecho status typically lag by a day or two, meteorologists interviewed on local stations emphasized that the storm had already traveled well over the 240-mile threshold with near-continuous severe wind reports, making derecho classification highly likely.National outlets explaining the event have been reminding listeners what sets derechos apart. Time and other explainer pieces have noted that a derecho is defined not just by strong winds, but by the combination of longevity, geographic extent, and mostly straight-line wind damage that can rival that of numerous tornadoes along the track. Scientists quoted in those articles point out that in summer-like patterns, a corridor of hot, humid air to the south and cooler air to the north can focus the jet stream and help ignite these fast-moving arcs of thunderstorms that then feed on that contrast for hours.In this week’s case, forecasters stressed the importance of treating severe thunderstorm warnings as seriously as tornado warnings when a potential derecho is unfolding. Local weather offices urged people to move to interior rooms or basements, stay away from windows, and be prepared for extended power outages with charged devices, battery-powered radios, and backup light sources. Utility crews across the impacted states have warned that full restoration could take several days in some rural corridors where lines were snapped repeatedly along the track.There has also been renewed discussion among researchers and emergency managers about how to communicate the risk of derechos more effectively. They argue that many people still associate life-threatening winds only with tornadoes or hurricanes, even though recent Midwestern derechos have caused multibillion-dollar damage and long-duration blackouts. Some climate researchers interviewed in regional coverage note that warmer, more humid summers may be increasing the frequency of environments capable of supporting such intense convective windstorms, though the long-term trends are still being studied carefully.Thank you for tuning in and following this breakdown of the latest destructive windstorm sweeping across the heart of the United States.
