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.

November 29 - Long Range Summary

Above average warmth which predominated the majority of the West and northern Plains throughout November is quickly expanding eastward, with the Northeast last to shift warm. A cold start to the coming week across the Northeast featuring temperatures 5° below average is certain to briefly reverse 5° above average midweek, before cold air returns at the end of the week. All models prolong this modest volatility across the Northeast characterized by near seasonal mean temperatures when averaged over several day time scales through the end of the 1st full week of December. Extended range models eventually flood the Northeast with milder air during the 11-15 day period, but this accompanies large scale pattern change directing notably colder air through west central Canada into the Rockies and Plains. Central U.S. cooling forecast to start late in the 6-10 day period may not mark onset of sustained below average temperatures. However, that is not the case across Canada where progressive cooling sets the stage for significantly colder mid December conditions across the northern Plains and Upper Midwest, which are likely to expand into the East by the final week of the month to persist through early January.
