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.
December 16 - Long Range Summary
Below average temperatures lingering in the Northeast this past weekend are not extreme but are several degrees colder than models forecast as arctic air typically erodes slowly. Warming in the wake of last week’s intense arctic air outbreak will continue to be limited through the 1st half of this coming week by snow and/or ice events models forecast across the northern U.S. and as far south as the southern Appalachians as several milder Pacific storms eject east of the Rockies. More importantly a strong midweek storm exiting the East Coast is forecast to tap into the coldest arctic airmass yet in Canada virtually ensuring plummeting late week temperatures across the Eastern 3rd of the country extending deep into the Southeast and Florida at 15° below average intensity or greater by this weekend (Dec 21-22). Unlike most arctic air outbreaks observed since Thanksgiving a less intense glancing blow of cold air spilling into the central U.S. will only produce slightly below average temperatures across Texas. Milder temperatures in the central-southern Plains are related to much warmer model shifts across Western North America generating several days of record warmth across the Desert Southwest (near 80°) during the latter half of this week. Longer range implications of strong Western warming scouring arctic air out of western Canada extend milder flow across the Eastern half of the U.S. potentially producing the longest stretch of above average temperatures yet this winter between the end of December into early January. Latest 30-day MWA ensemble runs also latched onto this warmer 11-15 day signal, but still sharply cool the Eastern U.S. below average much of January starting early in the 2nd week of the month. In support latest CFSv2 model mean January forecasts continue to trend colder favoring predominance of seasonal to below average midwinter temperatures 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.
