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.

March 18 - Long Range Summary

Seasonably cold temperatures east of the Rockies predominate the week ahead, along with fast moving light-moderate snowstorms whisking between the northern Plains and Northeast. Temperature volatility related to the northern tracking storm sequence focuses coldest air into the Northeast (5°-10° below average) in 2 distinct surges; early week (Monday-Tuesday), and late week (Friday-Saturday) with brief midweek warming in between. Meanwhile in the Southwest another large winter storm (much weaker than last week) is forecast by all models to develop over Arizona by midweek. Model forecasts diverge substantially in eastward track, strength, and speed of this Southwestern storm as well as the next Pacific storm lined up to slam onto the West Coast next weekend (Mar 23-24), greatly impacting 6-10 day temperature forecasts across both the West and East. However, all models indicate this storm as the start of a milder Spring pattern overall. Despite forecast uncertainty associated with generally slow eastward translation of each relatively mild spring storm across the U.S. this pattern change in itself virtually ensures progressively warming Eastern temperatures during the final week of March, and across the West by early April adding confidence to a mild April overall devoid of significant cold anywhere in 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.
