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 13 - Long Range Summary

Record setting triple digit high temperatures observed in the Dakotas this past weekend are part of widespread above average heat across the majority of the northern half of the U.S. and nearly the entire West, which have characterized all of August to date and are forecast to predominate the next 10-days. Models are far less certain in precipitation details (and associated seasonably cool temperatures) generated by weak disturbances slowly moving between the central – southern Plains and the Ohio and Tennessee Valleys. However, rainfall observed in most of Texas has underperformed model predictions, and all latest guidance is faster to re-establish dry conditions and moderate warmth (mid-upper 90s) by midweek. While some precipitation may return to the Deep South next weekend (Aug 18-19) and intermittent Eastern rainfall will linger into the 6-10 day period, by the 11-15 day period more long range models are latching onto establishment of far more sustained dry and warm conditions across the Midwest, South and East in a midsummer-like pattern on track to predominate late August and most of not all of September.


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.
