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.

December 2 - Long Range Summary

A winter storm underway across the Northeast will be notable for its prolonged duration into Tuesday; generating widespread heavy snow (1-2 feet), and several weaker disturbances lined up to follow reinforcing below average temperatures across the Northeast (coldest over fresh snowcover) for more than 1 full week. However, even the coldest air surging deep into the Southeast early this week (Monday and Tuesday) is not of arctic origin, and will quickly warm back to above average temperatures by midweek along with the entire central U.S. Pacific storms moving through the West this week are also devoid of extreme cold air and noticeably milder than observed last week. While extended range model forecasts are uncertain in timing details at some point by late next week (after Dec 10) both the West and Northeast will also noticeably warm, as a mild pattern by early winter standards becomes fully established across the U.S. and southern Canada. Seasonal temperatures between the northern Rockies and northern Plains appear to be main exceptions to near coast to coast above average warmth forecast to predominate mid-late December. The north-central U.S. also remains forecast by the 30-day MWA ensemble to be the initial focus of returning arctic air during the final days of December (after Christmas), marking early stages of a frigid Eastern half of the U.S. by early January.

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.
