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.

July 16 - Long Range Summary

The latest surge of noticeably hot and muggy air across the Midwest and Northeast persists until a pattern changing cold front drops both temperatures and humidity near seasonal midsummer levels by midweek. However, model forecasts continue to contract the core of greatest and most sustained cooling farther north and west from the Upper Midwest into the Ohio Valley, and even these regions are not consistently below average through the next 10-days. Development of wet conditions across the Southeast this week quickly re-establishes elevated humidity along the entire Eastern Seaboard, extending back into the Northeast by the start of the 6-10 day period which is a warmer signal favoring several degree above average overnight lows). Meanwhile triple digit heat building across nearly all of Texas early this week is forecast to warm further by Thursday reaching near record or record levels approaching 110° in northern areas of the State (including Dallas). This strong mid July heat in the central – southern Plains also extends to Southern California by next weekend (Jul 21-22) initiating another multiday extreme heatwave in coastal cities and adjacent areas including Los Angeles and Burbank. Most longer range forecasts effectively end cool conditions in the north-central U.S. during the final 5-days of July, setting the stage for return of coast to coast above average warmth to predominate the 1st half of August.


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.
