"The quality of your products is second to none."

— C. Brian Batey

"Thanks Tim for your quick response (we like that at FedEx) about our Professional Versions! As we're a 24/7 operation, we're look forward to augmenting our present weather system with Digital Atmosphere."

— Mel Bradley, FedEx Operations

"Wow. Your books are incredibly technical and useful. I consider myself a very amateur weather watcher and feel that I am already ahead of the curve. Thank you."

— Terry W. Taylor

"The NEXRAD support is truly awesome and easy to use and the other feature just really tops it off. This is about my sixth email tonight the other five being to other spotters in the area telling them they just have to download Digital Atmosphere and give it a serious going over."

— David Cashion

"I'm really looking forward to the next phase of Digital Atmosphere Workstation. I'm sure it will be as excellent as all your other products."

— Simon Keeling
Weather Consultancy Services, UK

"I run and manage a number of festival type events and Digital Atmosphere is able to produce charts that I can use for normal weather forecasting with a fair degree of accuracy and in particular wind speed and direction that is crucial to many of events."

— Robert Connolly, GI7IVX

"The archive data arrived today. WOW! What an amazing set of data! Thanks again for all the extras that you included as well!"

— Bryan Bollman, IA

"We do run GEMPAK and all the Unidata software also, but your package has numerous advantages, the biggest being Windows."

— Anonymous

"I am very impressed with what you have done. I have already shown several people at work your site. I plan on talking to our MIC [Meteorologist In Charge] soon to see if we can get Digital Atmosphere in the office to complement/supplement AWIPS."

— Ken Simosko, NWS, Pocatello

"This new version is even better than the older version which was awesome! Your programming skills and met knowledge amaze me!"

— Chris Kincaid

Current Weather Maps

Contained on this page are sets of large, high-resolution surface maps. They will produce optimal results when printed on an 11 x 17" printer such as the HP 5000 Laserjet or Epson 1520. Some of the maps have surface plots only, as those are intended for manual ("hand") analysis. The isobar maps will give a more complete depiction of conditions. These maps are all produced using Digital Atmosphere weather analysis package.

All maps use the legacy NMC/NCEP bitmap fonts developed by programmer Gloria Dent in the late 1960s. Since they are highly readable and were used on National Weather Service weather fax products for many decades and continue to be used now at NCEP, we have converted them from their FORTRAN implementions and include them as an optional font in Digital Atmosphere (File > Font Mode > NMC) and they are demonstrated here in these charts. The exception is the European topographic chart, which uses normal Truetype fonts.
