Updated March 21, 2008
NEW! Automated WXSIM forecasts for Atlanta, updated six times a day, along with current conditions, are available here. Also see a list of links to users' WXSIM forecasts on the web.
Version 11.8.6 Released!
Also, convenient, new ordering options.
Version 11.8.6 introduces the ability to compare saved forecasts with actual home station data from Ambient's Virtual Weather Station (VWS), as well as from Davis WeatherLink and Brian Hamilton's Weather Display WXSIMATE (see below) now also enables use with VWS. There are also new (as of Version 11.8) recommendations for GFS bias adjustments in light of GFS model changes in May, 2007. A new quick start guide, no available on the Downloads page, should help new users get oriented to the program much more quickly. Version 11.3 introduced use of GFS data from GRIB files processed by Chris McMahon, and WXSIMATE's ability to download this data, is now available for download, for both existing customers and anyone trying WXSIM out for the first time - for free, of course! If you haven't tried the program since versions 10.x, your in for a number of other pleasant surprises, including automated downloading and forecasting and the ability to directly compare forecasts with actual results from home weather stations. Also, see below concerning the new version, 3.9.2, of WXSIMATE. The price for customization (an extensive process in which I tailor the program specifically for YOUR site) is now $89, and you can now order directly from this site. To learn what's new, see New Features and Revision History . To get it now, see the Downloads section. NOTE: installing this version will NOT overwrite versions prior to 10.0, so you can safely try it out in parallel with pre-10.0 versions (it goes in the same directory, but uses different file names).
Discussion board
See the Weather-Watch forum, operated by Chris McMahon (who also made the new GFS data mentioned above available), at http://www.weather-watch.com/smf/. This has been active for some time, but I haven't pointed it out before on this page. Also, on WXSIM's "child" board "WXSIM Display Utilities", you can find how to post output on web pages, including translation into several foreign languages - for free! Thanks to numerous WXSIM users, including Ken True, for being so industrious as to come up with this!
Upgrade policy
Before Version 10.0, I hadn't charged an upgrade fee in at least 7 years, through over 50 steadily improving versions. Versions 10.0 and 11.0 were major upgrades, though, so if you are upgrading from a pre-10.0 version, there is a one-time fee of $30. This will get you a unique registration code which will unlock the program for use with your existing custom site; otherwise it will default to Atlanta. I will not be charging any more WXSIM upgrade fees until at least 2009.
Also, the WXSIMATE data collection tool, Version 3.9.2 available for download.
WXSIMATE is a very handy and time saving tool for collecting internet data as well as home weather station data, for easy import into WXSIM. It can now be scheduled to run automatically, to collect data for WXSIM even while you're asleep, and can also now gather local station data over the internet. A brand new feature is the ability to import data from Ambient's Virtual Weather Station, as well as from Davis WeatherLink and Breian Hamilton's Weather Display. Version 3.9.2 updates the URL for FOUS data from Ohio State, as they recently had an outage and brought the data back with different URL's.
To see what's new in WXSIM, see New Features and Revision History. Also see News Briefs and the WXSIMATE section of this page. For a review of (an older version of) WXSIM, or if you wish to order there by credit card, take a look at Tim Vasquez's Weather Graphics page. I now accept orders through PayPal (including a credit card option), in addition to checks or money orders.
To download
Version 11.8.6 of WXSIM, for IBM compatibles with Windows 98 and later,
either click here or go to the Downloads
section of this page. This shareware program is fully functional (no time
limits, and nothing disabled) and even includes the User's Guide! The main
incentive to register (aside from the fact that this is a very valuable
program that took many years to create) is that - for full accuracy and
convenience in forecasting for a particular site - customization for that
site is necessary. This is a service that I perform upon receipt of your
order, and I then forward the modified files to you. Note
to current users: As always, you can easily upgrade from this site. After
the $30 upgrade to 10.x or 11.x, upgrades will be free until at least 2009.
If you decide you want a new customization job, contact me at eburger@aol.com
about reduced rates for re-customization.
