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.

October 15 - Long Range Summary

Summerlike warmth which dominated the Midwest, East, and South during the 1st half of October is effectively over, except Florida where new heat records are likely this week. Winter-like cold air (20° below average or more) extending deep into the southern Plains (Texas) early week reaches the Northeast and mid Atlantic region midweek at less extreme intensity (5°-10° below average). While a 2nd reinforcing surge of seasonably cold air is forecast to focus more directly into the Great Lakes and Northeast by next weekend (Oct 20-21), all models agree above average warmth building across the West this week will spread into the same areas of the north-central U.S. and Canada which are currently coldest. The warmer consensus in government models virtually ensures the coming week of below average temperatures across the East and South is temporary, though full reversal back to above average warmth appears delayed to late in the 11-15 day period by precipitation. However, 30-day MWA ensemble forecasts which were 1st to sense eradication of arctic air from Canada re-establish widespread above average temperatures across the U.S. to dominate late fall.


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.
