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 21 - Long Range Summary
Canadian air surged into the Upper Midwest and Northeast during the past weekend cooling daytime high temperatures sharply (30° in 24-hours in Chicago). Unlike earlier in April this cold air outbreak is only slightly below average due to strong warming immediately ahead of the surface cold front which produced the warmest temperatures of the year across the Northeast yesterday (mainly 70s-80s), and little to no cooling penetrated farther south into a more resilient warm airmass entrenched in the Southeast. Warm air residing in the South ensures below average temperatures across the Great Lakes and Northeast will remain brief and quickly warm again by Tuesday, in a milder spring-like pattern maintaining late April temperatures mainly between seasonal and slightly above average levels. The West is also warming quickly in the wake of last weekend’s winter storm which produced widespread 15°-20° below average temperatures and substantial snow deep in the southern Rockies. Additional Pacific storms lined up to move into the West are significantly milder focusing seasonal to slightly below average temperatures mainly along the West Coast through late April. Spring-like volatility clouds the picture in longer range forecasts, but most extended range models are latching onto the next fundamental pattern transition early in the 1st week of May shifting periodic weak cooling (seasonal- slightly below average) to the Great Lakes and Northeast, which latest 30-day MWA ensemble forecasts maintain into late May. The Plains and Midwest remain the focus of heaviest spring rainfall which will be important to monitor going into summer, but reversal of expansive drought in the West and Plains is unlikely favoring these west central regions for early onset of summer-level heat before May is out.
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.
