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.

September 26 - Long Range Summary

Canadian air draining into the Eastern half of the U.S. is certain to finally replace excessive heat in Texas (mid 90s-low 100s) observed through most of September with near seasonal temperatures (mid-upper 80s) and noticeably lower humidity to predominate this final week of the month. Coldest temperatures farther north are forecast to peak this workweek near 10° below average across the Great Lakes and Ohio Valley, and Northeast.  Meanwhile summerlike heat contracting into the West during the 1st half of this week generating near record temperatures in Southern California (100° in Burbank), is faster to spread east of the Rockies in a modified (weakening) form starting in the Plains (mainly 80s-low 90s) by early this weekend according to recent model consensus. Timing of arrival of seasonably warm air into the Midwest and East is less clear as forecast tracks of Hurricane Ian through the eastern Gulf of Mexico into Florida and the Southeast Wednesday-Thursday are more uncertain than typical, with exceedingly slowing speed of the cyclone in weakening steering flow ensuring heavy tropical rainfall will persist over some portion of the Eastern Seaboard well into next week. However, all extended range models are trending progressively warmer across the eastern 3rd of the U.S. by the 11-15 day period adding high forecast confidence to an unseasonably  warm October overall  across nearly all of the U.S. likely to persist into early November.


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.
