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.

June 10 - Long Range Summary

Canadian air draining east of the Rockies ensured a noticeably cool start to this week by early summer standards all the way from the southern Plains through the entire Midwest to the northern mid Atlantic region and Northeast.  Now that Eastern pattern change completed model forecasts agree Monday will represent the coldest day of the next 2-weeks. Late week warming east of the Rockies will be gradual and limited in duration before near record heat reloading across most of the West by midweek (with exception of the cooler Pacific Northwest) spreads east of the Rockies during the 6-10 day period to peak in the low-mid 90s across the Great Lakes and Northeast for multiple days next week. Longer range forecasts indicate the core of greatest heat will shift westward between the Upper Midwest and northern Plains during the 11-15 day period. However, significantly drier conditions accompanying next week’s substantial surge of heat east of the Rockies is part of far more stable summerlike flow anticipated to preclude return of unseasonably cold air through the rest of June. Models focus lingering less widespread rain into the Upper Midwest and along the Gulf Coast which may periodically cool these regions near seasonal temperatures but longer range forecast confidence is increased drier conditions overall compared to spring and the start to June, coupled with persistent summerlike low amplitude flow aloft, set the stage for progressive warming of near sustained above average temperatures through July.


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.
