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.

September 24 - Long Range Summary

Near seasonal high temperatures in the 60s across the northeastern quadrant of the U.S. last weekend, while summerlike 90s persist across the Southeast are a harbinger of a sharpening airmass contrast set to predominate the next 10-15 days. One more surge of unseasonably warm air across the Great Lakes and Northeast early this week is forecast to peak Wednesday near 10° above average (70s-low 80s), at the same time the coldest air since last spring dives into the northern Rockies and northern Plains cooling highs mainly into the 50s. However, greatly improved model consensus substantially limits eastward and southern expansion of cold air into the Midwest, South, and East as lobes of reinforcing cold Canadian air focus more directly into the north-central U.S. into next week leaving both the Southeast and Southwest in persistent above average warmth. Much of this stagnant and blocked pattern is related to colder model forecasts in the Northwest U.S. However all long range model forecasts limit duration of sharp temperature contrasts, signaling return of near coast to coast moderate above average warmth by the end of the 11-15 day period setting the stage for a mild October overall.


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.
