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.

November 12 - Long Range Summary

Frigid week ahead across the Eastern half of the country; as the coldest temperatures of November 15°-20° below average peak in the Plains and Midwest early week (Monday-Tuesday), and near 15° below average in the East midweek (Wednesday-Thursday). Latest models are colder for longer especially in the Northeast as more widespread interior snow than previously forecast accompanies a coastal storm on Tuesday, and is followed by development of another storm along the East Coast next weekend (Nov 17-18).  However, at the same time fundamental late week pattern change is certain to be underway, flooding the western two thirds of the U.S. with mild Pacific air by the end of the 6-10 day period. All models agree this warm airmass will continue to advance eastward during the 11-15 day period, though some runs delay full arrival of above average temperatures into the Northeast and northern md Atlantic region until later in November. Regardless of timing details in full establishment of coast to coast above average warmth, contraction of polar air into northern Canada during Thanksgiving week in concert with low amplitude flow virtually ensures a mild end to November and 1st half of December across the U.S. However, the 30-day MWA ensemble is beginning to sense arrival of true arctic air to southwestern Canada in early December, setting the stage for a colder 2nd half of the month across the majority of the U.S.


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.
