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.

January 14 - Long Range Summary

This week starts cold along most of the Eastern Seaboard in the wake of the weekend winter storm which produced significant snow and ice across the Midwest and mid Atlantic region. Most of this new snow will melt this week as the mild Pacific flow pattern of early January persists for several more days focusing well above average warmth from the Plains (including 70s in Texas) to the Southeast. However, all models have aligned to major and prolonged pattern change fully replacing mild maritime flow with reinforcing arctic air outbreaks extending deep into the eastern half of the U.S. by next weekend (Jan 18-19). Models are also trending more extreme with intensity of arctic air during the climatologically coldest period of winter (final week of January through 1st week of February). However, latest government model forecasts are still not considered cold enough as 30-day MWA ensemble forecasts are more aggressive to develop blocked flow. Regardless of magnitude of cold air, below average temperatures are of increased confidence to dominate most of February across the Midwest, South, and East.


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.
