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 19 - Long Range Summary

The 1st half of this week is certain to feature the most widespread excessive heat and elevated humidity of summer nearly from coast to coast in which several new records are likely in the West, Plains, and East (mainly mid Atlantic region). This surge of heat will also represent the hottest temperatures of August for the Great Lakes, Ohio Valley, and Northeast,  though these areas cool by Thursday for a 2-3 day period of seasonal to slightly below average temperatures. However, along the West Coast where models once indicated a cold end to the week, latest runs are totally opposite and indicative of early stages of development of a stable midsummer-like large scale pattern across North America and adjacent Ocean sectors. This virtually ensures resumption of above average heat in the Northeast next weekend (Aug 24-25) in a more sustained manner which extended range models are still struggling with.  Forecasts valid during the transition from late August to early September (11-15 day period) are considered too cold, albeit successive runs cannot settle on which areas between the Rockies and East Coast will be coldest.  In contrast 30-day MWA ensemble forecasts remain much warmer during this period and beyond, which is far more consistent with large scale atmospheric teleconnections favoring a summerlike warm majority of September from coast to coast.


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.
