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.

April 12 - Long Range Summary

Large scale pattern reversal and stagnation is directing reinforcing shots of unseasonably cold air (and late season snow) into the same regions of the north –central U.S. which have been warmest through the 1st half of spring. Model forecasts continue to increase magnitude of cold Canadian air focusing between the northern Rockies and Upper Midwest early this coming week to levels typical of early March; featuring high temperatures in the low-mid 30s, and overnight lows in the teens and 20s. Model forecasts generally agree the cold early week northern U.S. airmass (15°-20° below average) will settle more south than east while modifying (weakening), to focus into Texas and the Deep South at less than 10° below average intensity by the end of this workweek to predominate the 6-10 day period. Farther east predominance of overcast skies and intermittent rain signal less extreme cooling near seasonal temperatures starting early this week, which will still be very noticeable in the wake of past weekend early summer-like high temperatures in the mid-upper 70s observed across the Northeast. Moderately cold air is forecast to spread through the East in a more transient manner during the 11-15 day period as the current blocked pattern breaks down. Soon thereafter warm air expanding across the entire West during the next 10-days will quickly flood the Eastern U.S. by the end of April, to predominate May according to 30-day MWA ensemble forecasts.
