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.
July 22 - Long Range Summary
Sharp west – east contrast in place across the U.S. is certain to persist into the middle of this week; separating excessive triple digit heat in most of the West, from mild below average temperatures by midsummer standards (mainly 80s) across the majority of Midwest, South, and East. Now that the anomalous amplified pattern driving these temperature anomalies is near peak model forecasts aligned markedly with important aspects of relaxation back to widespread summerlike flow before July is over. Not only are all extended range models fully onboard with eastward expansion of Western heat this week across the northern half of the U.S. all the way to the East Coast by next weekend (Jul 27-28), but recent forecasts are significantly hotter across the Great Lakes, Ohio Valley, mid Atlantic region, and Northeast with most generating a heatwave (3 consecutive days or more of 90s) into early the following week (Jul 29-30). Model forecasts valid during the 11-15 day period (early August) are less aligned but all generate varying degree of moderation across the Midwest (seasonal at best), after which longer range guidance re-establishes well above average heat for a much longer period into late August. Seasonably cool and wet conditions currently focusing between the southern half of Texas and the lower Mississippi Valley are forecast to linger the longest into the 1st week of August, but drier conditions and above average temperatures are on track to resume and predominate the majority of the final month of summer. Models are also weaker and briefer with temperature moderation across the West; including coldest areas of the Pacific Northwest which only drop slightly below average this workweek, before warming to less extreme but prolonged above average temperatures (upper 80s-low 90s) starting by the coming weekend (Jul 27-28).
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.
