Commodity Weather Group
Commodity Weather Group, known in its market as CWG, is a Bethesda, Maryland firm that provides weather forecasts and analysis for commodity, agriculture and energy traders. Launched in April 2009 by forecasters Matt Rogers and David Streit, it built a subscription business on a specific insight: for the people who trade natural gas, power and farm commodities, weather is not background information but a price. A colder November means more heating fuel burned. A hot, dry fortnight in the Corn Belt means a smaller crop. CWG's daily work is to translate atmospheric change into those commercial consequences early, clearly and often, for subscribers across the energy and farm sectors, as its directory entry describes.
The firm is small by headcount compared with the national weather media companies, and that is part of its model. Contemporary profiles described a small team of meteorologists working from a suite of offices in Bethesda, keeping overhead low and communicating frequently with a client base that pays for judgement, not page views. CWG has been described as a fast-growing consulting group for commodity weather support with a special focus on energy and agriculture. Its founders and forecasters are quoted in national energy reporting and write for a general audience through the Washington Post's Capital Weather Gang, giving the firm a public visibility larger than its size.
Launch in 2009 by EarthSat veterans
CWG was launched in April 2009. A 2010 alliance announcement described the team as including EarthSat veterans David Streit, Ken Wells, Matt Rogers, Joel Widenor and Jason Setree, offering a combined 75 years of experience in the sector. EarthSat's weather operation in Maryland was one of the established names in commodity forecasting, and CWG's founding team carried that lineage into a new, independent firm. The George Mason University alumni magazine, profiling Rogers, likewise reported that Rogers and co-founder David Streit started Commodity Weather Group in 2009 to make long- and short-term forecasts for companies that have pricing at risk in the commodities sector.
The timing deserves attention. CWG was not founded by newcomers spotting a trend; it was founded by experienced commodity forecasters setting up on their own at the end of a decade in which energy markets had become intensely weather-sensitive. Natural gas trading in particular had made the two-week temperature outlook a market-moving document. A small firm, owned by the forecasters themselves, could compete in that world if its forecasts were good and its communication faster and more direct than a larger bureaucracy's.
Matt Rogers and David Streit
Matt Rogers, CWG's co-founder and president, received his meteorology degree from Penn State in 1994 and later combined forecasting with business training, earning a Master of Business Administration from George Mason University's school of management in 2001 through night classes that suited a forecaster's schedule. In the Mason profile he explained the economics of the niche frankly: many weather service and small-market television jobs do not pay especially well, while commodity forecasting is a niche in which a non-television meteorologist can earn more — and a low-overhead firm can reward its team and reinvest. Rogers also contributed to the Capital Weather Gang, the Washington Post's weather column, a dual role that kept a forecaster for traders in touch with public weather communication.
David Streit, co-founder and chief operating officer in the firm's leadership listings, brought the agricultural side of the partnership and a longer market history. A later expert-call biography recorded that Streit began working with the agricultural commodity industry in 1981 on Wall Street, that growing up on a working farm helped him develop insight into how weather and agriculture interact, and that he participated in the expansion of the energy commodity industry in the 1990s. That combination — farm upbringing, Wall Street commodity experience and energy-market expansion — mirrors CWG's dual focus. Leadership listings for the firm have also named Jason Setree in a finance role and Joel Widenor as chief administrative officer and director of agriculture services, consistent with a structure in which the founding forecasters also run the business.
What CWG sells
CWG provides a full short-, medium- and long-range forecast service and offers frequent updates on key market-moving weather events, maintaining high levels of communication with its client base. In practice that means daily reports for energy and agricultural subscribers, seasonal outlooks, and rapid comment when a model run or an observed change alters the commercial picture. Its audiences, as described by Rogers, include power traders, gas companies, banks and agriculture organisations — buyers for whom a forecast is an input to positions worth far more than the subscription.
The subjects follow the commodities. For energy, the governing variables are temperature-driven demand: heating demand in winter, cooling demand in summer, and the regional distribution of both across the population centres of the United States and Canada. For agriculture, they are rainfall, temperature and extreme events across the growing regions of North and South America and other world crop areas, timed against planting, pollination, filling and harvest. CWG's seasonal and short-range forecasts are distributed to subscribers across both sectors, and its forecasters are regularly invited onto expert calls for financial audiences — for example, a 2025 Jefferies event in which CWG experts were to discuss a spring weather outlook and its potential impact on agricultural, agrichemical and industrial markets, crop yields and energy spreads.
How its forecasts enter public reporting
Because energy journalism needs a named forecaster when weather moves prices, CWG appears frequently in wire and trade reporting. In November of a notably cold year, an Associated Press energy story quoted Rogers observing that the cold had come in hard and strong, that a cold November does not necessarily mean a colder winter, but that it depletes fuel supplies and pushes prices up — a compact example of the CWG style, tying an observation to inventories and price in the same breath. The same story recorded his view that there was good consensus for a cold winter overall, in a market where natural gas futures had risen sharply over preceding days on the changing forecast.
A Bloomberg account carried by the Claims Journal in August 2013 likewise quoted Rogers, as CWG's president based in Bethesda, forecasting temperatures several degrees above normal through the Midwest into New England, while noting that the heat would not rival an earlier July heat wave. These citations show the firm's working relationship with the financial press: journalists call CWG because its clients' money rides on the same numbers, which makes its forecasters natural explainers of weather-driven market moves. For a directory of agencies and services, this is CWG's syndication function — not a wire it owns, but analysis that travels into energy and commodity coverage worldwide.
The Speedwell alliance and weather risk
In March 2010, CWG and Speedwell Weather announced an expanded alliance. Speedwell supplied weather data under agreements with national meteorological services and provided a weather derivative pricing and risk management system, described as the definitive system of its kind, offering pricing tools, portfolio management and back-office functionality for the weather derivative market. The pairing was complementary: CWG forecast the weather and interpreted its market meaning, while Speedwell's systems handled the data and financial machinery of weather risk contracts. The announcement presented CWG as the fastest-growing consulting group for commodity weather support in its areas — an early marker of the young firm's trajectory within a year of launch.
The alliance also places CWG in a wider risk ecosystem. Weather derivatives and related contracts let energy and other firms hedge the financial effect of temperatures that are warmer or colder than normal. Pricing such contracts needs both trustworthy historical data and credible forecasts. A forecaster who serves traders and a data firm that serves derivative desks are adjacent parts of the same market, and their alliance acknowledged that weather risk had become a financial product in its own right.
Energy forecasting in practice
The energy side of CWG's work turns on a chain of reasoning its forecasters perform daily. Temperatures across major consuming regions are aggregated into demand expectations; storage and supply conditions determine how much a demand surprise matters; and the forecast horizon — days, weeks or a season — determines which decisions a client can still change. A cold outbreak forecast for January and February, to use the pattern from the Associated Press reporting, matters more when fuel supplies have already been drawn down by a cold November. CWG's value is less in any single temperature number than in maintaining that chain of context continuously, so a client hears not only that it will be cold but what the cold means given the state of the market.
Seasonal outlooks extend the same reasoning. A winter or summer outlook from CWG is discussed by chemical, agricultural and industrial analysts because seasonal temperatures affect fertiliser and chemical demand, farmer confidence and equipment demand, and consumer-facing markets, as the Jefferies event description listed. Weather at seasonal range is probabilistic and uncertain, and CWG's forecasters present it as risk assessment — the balance of scenarios and their commercial consequences — rather than as a promise about a particular week months ahead.
Agriculture forecasting in practice
On the farm side, Streit and the agriculture service bring the firm's second discipline. Crop weather is regional, timed and cumulative: rain that is welcome in June can be damage in October, and a forecast must be read against the crop's stage and the soil's existing moisture. Streit's background — a working farm upbringing and commodity work beginning in 1981 — is the firm's credential for that reading. CWG's agricultural output addresses global crop conditions, not only American fields, because grain and oilseed prices are set in world markets; a drought in a competing exporting region moves the same futures price as a drought at home.
The firm's presence on financial expert calls about crop yields and sector rotation shows how agricultural weather analysis is consumed in the 2020s: not only by farmers and elevators deciding when to sell, but by equity and commodity analysts deciding what weather means for companies that sell seed, chemicals and machinery. CWG serves both audiences with the same underlying forecasts, framed at different distances from the field.
A small firm model in a big industry
CWG's structure is a study in the economics of specialist information. It does not operate a television network, a consumer website or a national newsroom. It operates expertise: a handful of experienced forecasters in Bethesda, a subscription list in energy and agriculture, a habit of frequent updates, and a reputation that makes its partners quotable when weather moves markets. Rogers's stated preference for low overhead is the business version of that model. In commodity weather, the product is trust accumulated over many forecast cycles, and a small firm can hold that trust as effectively as a large one if its people are known and its calls are remembered fairly.
That model also explains the firm's longevity from its 2009 launch. Commodity weather demand did not disappear with any single market change, because the underlying exposure — crops in the ground, gas in storage, power to be generated — renews every season. CWG was built by veterans of that cycle, for clients who live by it.
Place among commodity weather services
Commodity Weather Group belongs to the private forecasting sector that grew up serving American energy and agriculture after government weather data became a foundation rather than a finished product. The National Weather Service provides observations, models and warnings to everyone; firms like CWG add interpretation, speed, commercial framing and a forecaster who will answer for the interpretation. Founded in Bethesda in 2009 by Matt Rogers and David Streit with a team of EarthSat veterans, allied early with Speedwell on weather risk systems, and cited for years in national reporting on heating demand, crop weather and market-moving forecasts, CWG is a clear example of that sector at its most focused — a small Maryland firm whose daily judgement is distributed, through subscribers and through the press, wherever commodity prices are made.
