Meteo 410 Resources

Key Data Resources for Meteo 410

Forecast Progs

Grid Interpolations

  • Texas A&M Weather Interface (site includes a 48-hour archive for grid interpolations (and other forecasting tools). So, if you’re documenting a case study, you should be on your toes and save any relevant text data that supports your case)

MOS Tables

  • Penn State METEO 410 MOS page (a page with current and archived MOS tables for our WxChallenge cities)
  • Texas A&M Weather Interface (the same site as for grid interpolations; contains a short 48-hour archive)
  • University of Wyoming (in addition to tabular data, this page also includes MOS forecasts in meteogram format if you prefer that type of visual)
  • The Meteorological Development Lab (MDL) MOS page (a one-stop shop for all kinds of MOS output.  If you decide to explore some of the other types, make sure that you read the product descriptions so that you know what you’re looking at!)
  • Penn State MOS e-Wall (does not include MOS tables, but does provide national and regional plots of MOS data in various formats.  It’s helpful for a quick “big picture” glance at MOS data, but not really suitable for detailed analysis by itself)

LAMP Guidance

  • Real-time LAMP guidance (Stations are organized by state.  Make sure you note the “Latest Forecast Cycle” so that you know what model run your guidance comes from.)
  • LAMP product description (A very handy guide for helping you decode LAMP guidance)

USL Model

  • USL Model Output for WxChallenge (Site includes USL model output specifically for WxChallenge cities and forecast periods.  12Z and 22Z runs are typically available less than an hour after they’re initialized, so the 22Z run is usually available before the WxChallenge forecast deadline.)

SREF Data on the Web

  • SPC SREF Page:  A veritable gold mine of SREF data.  The various tabs at the top of the page expand to show the numerous forecast fields available.  The mean (“MN”), spread (“SP”), and probability (“PR”) of just about any variable you can think of are available.  Once you’ve loaded a loop of images, you can track the trend in SREF forecasts (compared to previous runs…a lagged-average approach) by clicking on the image. Take some time to investigate this page.  Being familiar with this page will pay off come WxChallenge time.
  • SPC Plumes Page:  You can generate plumes for a number of forecast fields (including 2-m temperatures, dew points, winds, QPF, etc.) for any of the stations on the map.  One cool feature is the ability to generate a plume showing the SREF means from the past few SREF runs (click on “Plot SREF run means (dProg / dt)”)
  • NCEP SREF Page:  Includes mean and spread plots, probabilities, and spaghetti plots of various forecast fields.  Also includes SREF forecasts for Alaska and Hawaii.
  • Penn State e-Wall:  Includes lots of really nice graphics showing forecasts from individual members and the ensemble mean.  Also includes some probability graphics.
  • FSU/NWS TLH COMET Experimental Forecast Confidence Graphics:  What constitutes a large or a small spread?  This page will help with that question.  It compares the spread of GFS ensemble forecasts to a “normal spread” to generate “forecast confidence” graphics for a variety of variables.
  • NCEP Cyclogenesis Tracking Page:  Since the paths of cyclones (both mid-latitude and tropical) impact areas of precipitation, etc., this page can come in handy.  It provides plots showing the forecast tracks of mid-latitude and tropical cyclones.
