---

Features

• Automated net script generation — fetches live NWS Area Forecast Discussions (AFD) and Hazardous Weather Outlooks (HWO) for all regional WFOs (GJT, BOU, GLD, PUB, CYS) and builds a complete, section-by-section net script
• Regional Weather Roundup — renders the NWS Pueblo RWR as a styled HTML table with color-coded temperature, wind, and conditions columns
• Weather Resource Toolkit — categorized quick-access panel linking to SPC convective outlooks, NWS office pages, radar & satellite tools, Skywarn resources, mesonets, and more
• Built-in web browser — opens dashboards in-app via PyQt6-WebEngine (optional; falls back to external browser)
• PDF export — generates a formatted, bookmarked PDF of the net script via pdflatex when TeX Live / MiKTeX is installed
• Session persistence — save and restore operator callsign, name, and location; auto-saves every 60 seconds
• Dark / Light / Blue themes — full Qt stylesheet theming
• Auto-advance mode — steps through script sections on a configurable timer
• Cross-platform — tested on Windows 10/11 and Linux (Ubuntu 22.04+)
