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 11 - Long Range Summary

Cold temperatures extending deep into the Southeast early this week in the wake of the recent historic southern snow event are certain to be followed by an even colder arctic airmass focusing farther north across the northeastern quadrant of the country by Wednesday at near 15° below average intensity. Models begin to diverge late week with intensity of warmer air spreading out of the Western half of the country into the East through early next week, but even the warmest 6-10 day forecasts shift markedly colder by the 11-15 day period. The coldest forecasts of the European model and 30-day MWA ensemble re-establish a similar amplified pattern as currently in place setting the stage for a frigid Christmas week across the Midwest and East, and are accepted as indication of an even colder start to January than previously anticipated.


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.
