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.

April 6 - Long Range Summary

A slow moving storm bringing significant rain and mountain snow to California early this week sets the stage for another strong warm-up east of the Rockies. However, above average temperatures peaking during the 1st half of this coming week are near certain to be the final unseasonably warm conditions across the Midwest, South, and East until late April. This is because all extended range models complete full pattern reversal late this week; establishing warm conditions across the West, and an extended period of polar air reinforcement deep into the Eastern half of the country. Only magnitude of temperature anomalies remain of model debate, with European model forecasts more extreme than GFS forecasts. The colder forecast scenario which overwhelms the Northeast with more than 10° below average temperatures late this week, followed by at least 2 additional winter-like cold air outbreaks during the following week of Apr 13, is most consistent with the coldest aligned atmospheric teleconnections since November.  This significantly cold mid April scenario is also similar to longer range forecasts of the 30-day MWA ensemble which gradually resume near sustained above average warmth across the Eastern U.S. during the final week of the month to extend into May.


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.
