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 16 - Long Range Summary

This week begins winter-like with record setting cold temperatures deep into the Plains and Midwest (20°-30° below average), and near 15° below average temperatures from the Northeast into the Southeast. Latest model runs have shifted colder through day-10 to the point of forecasting 2-3 day periods of similar magnitude below average temperatures as several additional large Pacific storms track from coast to coast across the U.S. tapping into lingering cold air in Canada. However, all longer range models signal varying degree of warming across the Eastern U.S. during the 11-15 day period. This milder model shift is consistent with long standing 30-day MWA ensemble forecasts which effectively end connection to significant cold air by the end of April; setting the stage for a far milder start to May characterized by warm-biased temperatures across the western two-thirds of the country, and gradual moderation across the Northeast to near seasonal late spring warmth. 


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.
