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 23 - Long Range Summary

As large scale pattern reversal continues to evolve models have latched onto stronger winter storms tracking coast to coast including an impactful Northeastern winter storm midweek. This winter storm is near certain to produce the most southern displaced snow in over one month between northern Texas by Tuesday to the southern Appalachians Wednesday, while drawing noticeably colder air into the Midwest and East much closer to seasonal midwinter levels. The coldest air focusing west of the Rockies during the coming workweek (10° below average or more in the Southwest), is still not of direct arctic origin. However, as pattern amplification peaks early this weekend (Jan 28) latest model consensus unleashes extreme arctic cold directly through the northern Plains and Upper Midwest at 20°- 25° below average intensity plummeting daytime high temperatures near zero and overnight lows into the negative teens. This is a colder for longer scenario than models indicated last week including well below average temperatures across the Great Lakes, Ohio Valley, mid Atlantic region, and Northeast during both 6-10 day and 11-15 day periods.  Mild air is forecast to return to the central and Eastern U.S. early in the 2nd week of February as less intense cold air contacts into the northwest quadrant of the U.S. However, as 30-day MWA ensemble forecasts extend deeper into February latest runs return arctic air to the central U.S by Feb 20.


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.
