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.

August 10 - Long Range Summary

This week begins with the warmest temperatures of August surging into the Northeast (upper 80s-low 90s) along with increasing humidity, which will likely prompt NWS to issue Heat Advisories in lower elevations of the region valid Monday and Tuesday. However, at the same time the next relatively cool (and wet) Canadian airmass of the early August series will be settling into the Plains and Midwest, albeit in a weaker form (near seasonal) than several degree below average temperatures observed between the Rockies and Appalachians all last week. This noticeably cooler air is certain to advance farther east to the East Coast by midweek; effectively ending extreme early week heat, while initiating wetter conditions across much of the Midwest and East. More importantly far greater model forecast consensus exists in prolonged duration of milder seasonal – slightly below average temperatures across the Midwest and East persisting into the final week of August along with wet conditions. A cooler end to summer and start to September across the Midwest and East is consistent with hotter Western forecasts, which recent model runs have latched onto as prolonged return of near 115° heat by the end of this workweek across  the Desert Southwest (including Phoenix) along with very dry conditions.


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.
