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.

May 14 - Long Range Summary

Near record heat began early May in the Southwest before progressively spreading eastward last week through the Plains and Midwest into the mid Atlantic region and Southeast, where it will linger into the start of this 2nd full week of May.  Moderate cooling in the Southeast starting Tuesday (still several degrees above average) accompanies clouds and rain advancing northward from Florida. What is more important is precipitation will become the only source of cooling going forward through the remainder of May as actual cold air retreats farther north into northeastern Canada. Fast weakening observed to a large Pacific storm once it entered the West late last week is a harbinger of a repetitive mild late spring pattern overall featuring mostly scattered convective type rainfall across the majority of the Plains, Midwest, and East favoring continued predominance of above average warmth. Warmer and drier May conditions which are the exact opposite to the end to spring observed last year signal a much hotter start to summer 2018.


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.
