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 22 - Long Range Summary
Unseasonably cold air in place across the majority of the Eastern half of the U.S. this past weekend will briefly moderate closer to seasonal temperatures after a very cold start to the day Monday featuring overnight frost conditions deep into the mid South and Southeast. However, a final surge of cold Canadian air forecast to focus more directly into the Midwest and East midweek has models shifting markedly colder (15°-20° below average) for a 1-2 day period Wednesday-Thursday along with some mountain snow in the Northeast. Late week pattern change is certain to effectively end cold air transport into the U.S. while directing less intensely cool Pacific storms back through the West. This will end the extended period of well above average warmth underway west of the Rockies into midweek, but periodic rain-cooled temperatures (mainly 7°-10° below average daytime highs) starting during the latter half of this week (Apr 25-27) will be far from extreme. As the West cools the warmest air yet this year will flood most of the Midwest and East generating near 15° above average temperatures more typical of late May or early June for several consecutive days during the 6-10 day period. Models are highly uncertain with timing, track, and strength of the series of Pacific storms once they eject east of the Rockies. However, rain-cooled Eastern conditions are near certain to remain weak with the 11-15 day period marking the 1st opportunity for multiple days of temperatures closer to seasonal levels, in an otherwise mild late spring pattern likely to be warmest (relative to average) across the northeast quadrant of the U.S. during most of May.
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.
