MWA is the only private weather forecast company in the world which has developed an operational 30-day weather forecast computer model.
The proprietary MWA Ensemble competed in 2010 is a global spectral model based on decades of research performed at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
Before MWA only the largest governmental weather forecast entities invested the resources necessary to develop and operate long-range dynamic numerical models. To this day the longest operational forecasts generated by these only extend out 15 days.
The 30 day forecast horizon of the MWA makes it ideal in identification of the timing and nature of important atmospheric pattern changes.
Computer generated forecasts are updated twice per day, 7 days per week, with all meteorological parameters displayed graphically; at the surface, and several upper level altitudes commonly utilized in weather forecasting.
Surface graphics include easy to understand 5 day composites of temperature anomaly and precipitation. Numerical surface parameters are also available in tabular form for over 200 North American cities.
Worldwide forecasts are generated for 6 additional continents. For clients interested in utilizing direct MWA ensemble numerical output to initialize in-house energy demand or pricing models comma delimited files are available.
February 19 - Long Range Summary
The coldest air of the season in place across the central U.S. (35°-40° below average) is quickly spreading south and east into the Deep South and the Northeast with only minor modification (weakening) over widespread snowpack which is also still expanding behind 2 distinct winter storms lined up to track from the Rockies to the mid Atlantic coast through the end of this week. NWS Extreme Cold Warnings and Advisories valid today across nearly the entire Eastern half of the U.S. (including the western and central Gulf Coast) are certain to be extended as all models maintain extreme double-digit below average anomalies through the end of this workweek. While this intense level of cold air at the surface can only be slow to moderate through the coming weekend (Feb 22-23) faster pattern change aloft is certain to intensify above average warmth already building across the Desert Southwest (70s-80s) near record levels next week (90s), and spread this warmth east of the Rockies in a progressively weaker form during the final week of February. In this scenario cold temperatures across the Plains from North Dakota to Texas reverse fastest and greatest, to double-digit above average anomalies by Monday, Feb 24. In contrast slower and far less intense warming across the Midwest and East (mainly 3°-6° above average) peaking later next week will also remain briefest and most prone to periodic moderate cooling into early March under lower heights aloft. Progressively greater forecast divergence separates extended range models with GFS forecasts currently coldest deep into the Midwest and East especially by the 11-15 day period. Unlike prior extended range modeling which attempted to substantially warm all of Canada all latest runs shifted notably colder north of the border, adding confidence to ultimate establishment of a north-south temperature gradient across the U.S. typical of La Niña. Longer range forecasts of both the CFSv2 model and 30-day MWA ensemble are latching onto this as leading to a markedly colder 2nd week of March featuring winter-like temperatures (highs mainly in the 30s) across the Great Lakes, Ohio Valley, mid Atlantic region, and Northeast strongly suggesting significant delay to the start of spring across the northeast quadrant of the U.S.
If your business or career depends on correctly predicting the weather, you can follow the pack or you can get ahead with MWA’s proprietary models and expert forecasts.
