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.

May 20 - Long Range Summary

This week begins with the warmest temperatures of the year in the Northeast (low-md 80s), before a brief surge of the coolest temperatures of the week sweep across the region Tuesday (60s). Meanwhile cold winter-like storms reloading over the West into next week are part of a stalled pattern already focusing strong heat (low-mid 90s) across the Southeastern quadrant of the U.S. All models peak Southeastern heat near record levels (11°-15° above average) late this week (Thursday-Friday) through the 1st half of the of  the 6-10 day period. Forecasts farther north are struggling with how much of this extreme Southeastern heat can periodically spread back into the Great Lakes and Northeast, with latest modeling trending warmer during the next 10-days. In the longer range all models totally breakdown anomalous amplified flow early in the 11-15 day period marking effective end to the current sharp west-east temperature contrast across the U.S. While seasonably cold air appears slowest to erode in the northern Plains during the 11-15 day period, sustained Western warming and moderating Southeastern heat are part of mild seasonably warm summer-like flow on track to predominate the majority of the U.S. through early summer.


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.
