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.

February 26 - Long Range Summary

Arctic air which surged through the Great lakes and Northeast late last week briefly generating double-digit below average temperature anomalies is considered likely to be the final winter-like cold airmass to reach the Eastern U.S. until next fall or winter. Progressive (fast) flow already scoured the transient arctic airmass out of the East late this present weekend, while record warmth continues to expand across more of the Plains and Midwest at 25°-35° above average intensity. Unseasonably warm central U.S. temperatures more typical of May than February are on the way eastward to peak near 70° as far north as Chicago and in the 60s across most of the Northeast during the 1st half of this week. Meanwhile air conditioners already running due to mid-upper 80° heat underway across the south central U.S. centered on Texas will be needed into Tuesday as temperatures peak in mid 90s ahead of a strong cold front ejecting out of the West Tuesday night. This colder air will be most intense across the northwest quadrant of the U.S. before progressively moderating as it spreads east of the Rockies, producing only seasonal to slightly below average temperatures at best across the Midwest Wednesday and the Northeast Thursday.  More importantly all models agree below average or seasonal temperatures in any one region of the U.S. this week will remain brief (1-2 days), before quickly reversing back to well above average levels for several consecutive days ahead of a weaker cold airmass poised to progressively shift from coast to coast next week (Mar 3-9). Longer range forecasts of the 30-day MWA ensemble indicate the 2nd half of March will not be as anomalously warm as the unseasonably warm start to spring across the eastern half of the U.S. However mainly precipitation-induced cooling devoid of arctic air favors the Southeast for coldest temperatures in late March (slightly –moderately below average), while most of the U.S. remains seasonably warm typical of El Niño.


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.
