New and Improved Forecasts
MWA updated its proprietary 30-day global weather forecast ensemble to the MPAS model (Model Prediction Across Scales), which was collaboratively developed by the National Center for Atmospheric Research (NCAR) and the climate modeling group at Los Alamos National Laboratory (COSIM). MWA modeling staff selected the latest update (Version 5) of this unique research model for conversion to an operational forecast platform based on several key features distinguishing MPAS from all other weather forecast models. Initial verification analyses show the model is highly stable and more accurate than the GFS model at forecast time scales beyond day-5.
The model is comprised of individual simulation components specific to atmosphere, ocean, land ice, and sea ice employing a unique hexagonal grid system especially suitable for higher resolution applications over any geographic area. Model output available to standard subscriptions include 30 day global forecasts of upper atmosphere and surface meteorological parameters; displayed graphically (including 5 day composites of temperature anomaly and precipitation), as well as in numerical form for over 200 cities. Forecasts specific to any city or global region can be customized to greatly enhanced resolution to satisfy individual user requirements
30 Day Weather Forecast:
This weather forecast newsletter is prepared by MWA meteorologists 3 times per week on Sunday, Tuesday and Thursday, and is often very different and in some cases totally contrary to direct computer model output. Each forecast update summarizes primary weather events expected to be of significance to the energy industry during the next 30 days, with an emphasis on forecasting substantial pattern changes that move markets. This format is designed to identify major trading opportunities in which markets may be moving in the wrong direction, based on government or private forecasts that are primarily repackaged computer model forecasts.
The format of the newsletter is designed to address a wide audience of traders and meteorologists. As such the broad based forecast presents a 30-day graphic in the 1st page, which depicts U.S. temperatures anomalies during the next 1-5 day, 6-10 day, 11-15 day and 16-30 day periods for easy comparison to computer models and other forecast providers. The rest of the document includes detailed discussion of the forecast basis with supporting weather maps.
90 Day Weather Forecast:
This long range weather forecast newsletter is released once per month and includes detailed assessment of the main atmospheric indices of interest to seasonal weather conditions. The forecast horizon is a minimum if 90-days, but can extends as much as 180 days depending on predictability of specific atmospheric patterns.
Similar to the 30 day newsletter (MWA 30) seasonal forecast maps and primary forecast basis are presented in a straightforward format in the 1st page. Detailed assessment follows describing major atmospheric features expected to drive weather conditions in an understandable format that provides the reader with the necessary tools to continually monitor the degree to which the long range forecast is verifying until the next update is issued. By describing the expected evolution of major atmospheric features expected to drive an upcoming season’s weather, the reader is equipped with the ability to most effectively utilize the forecast for trading decisions.
May 14 - Long Range Summary
Near record heat began early May in the Southwest before progressively spreading eastward last week through the Plains and Midwest into the mid Atlantic region and Southeast, where it will linger into the start of this 2nd full week of May. Moderate cooling in the Southeast starting Tuesday (still several degrees above average) accompanies clouds and rain advancing northward from Florida. What is more important is precipitation will become the only source of cooling going forward through the remainder of May as actual cold air retreats farther north into northeastern Canada. Fast weakening observed to a large Pacific storm once it entered the West late last week is a harbinger of a repetitive mild late spring pattern overall featuring mostly scattered convective type rainfall across the majority of the Plains, Midwest, and East favoring continued predominance of above average warmth. Warmer and drier May conditions which are the exact opposite to the end to spring observed last year signal a much hotter start to summer 2018.
