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 31 - Long Range Summary
Fundamental pattern change early this 1st week of April fully replaces last week’s record heat observed across most of the Western U.S. with well below average temperatures and substantial mountain snow measured in feet. Most of the Eastern half of the U.S. remains predominated by well above average temperatures, with exception of an increasing expanse across the northern tier including the Great Lakes and Northeast where periodic cold Canadian air reinforcement persists prompting NWS Winter Storm Warnings and Advisories in place this past weekend to be extended into this week. Improved extended range model alignment increases confidence next weekend (Apr 5-6) marks onset of prolonged winter-like cold (and snow) spreading progressively deeper into the Eastern half of the U.S. through midmonth, including double-digit below average temperatures deep into the Southeastern quadrant of the U.S. Since extended range model forecasts only recently latched onto return of winter-like conditions east of the Rockies during the 2nd week of April, subsequent runs are likely to increase intensity, coverage, and duration of well below average temperatures and very late season snow. Latest 30-day MWA ensemble forecasts prolong winter-level cold air reinforcement deep into the Eastern U.S. into the start of the 3rd week of April (Apr 13-16) before the next milder pattern shift begins aloft. However late month temperature moderation at the surface is likely to be very slow, especially if snowcover extends deep into the Ohio Valley and mid Atlantic region. All of this ensures April will verify markedly colder than March, potentially within the top-10 coldest on record east of the Rockies.
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.
