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.

December 10 - Long Range Summary

Cold air lingers for most of this workweek across the mid Atlantic region and much of the Southeast in the wake of the recent historic snowstorm. Additional precipitation is on the way to these same regions by the end of the workweek into next weekend (Dec 15-16), but strong warming to above average temperatures already underway across the majority of the Plains and Midwest will gradually expand into the East ensuring most late week precipitation will remain rain. Above average temperatures and more rain than snow across the Eastern half of the U.S. are part of a prolonged mild pattern by early winter standards which all recent model forecasts extend into late December. However, as government models with 2-week forecast horizons extend into the final week of December all latest runs are latching onto early stages of the next fundamental pattern shift re-establishing arctic air nearby in southern Canada. Government models appear to fast to dislodge arctic air into the U.S. as the 30-day MWA ensemble continues to delay onset of sustained below average temperatures to the 1st week of January. More importantly the long range model continues to indicate this as a highly stable cold pattern in which arctic air focuses more directly southward through the Great Lakes and Northeast to predominate mid-late January.


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.
