WSV3 Version V7.10

WSV3 Professional V7.10


N.B.: As announced in late 2023, further updates to first-gen WSV3 Professional 2015 are sustaining-operations-only (quality/stability/bugfixes) with all substantive new improvements and feature developments confined to the next-generation rewritten-from-scratch WSV3 Tactical Mesoanalyst product.

V7.10 is a special exception to that status quo because several upstream NWS/SPC data changes and high-impact operational issues required deeper work exposing high-value improvement opportunities in these limited areas.

1. Rewritten SPC Convective Outlooks Layer

V7.10 includes a rewritten and modernized SPC Convective Outlooks layer. The new implementation adds the new Conditional Intensity Groups (CIG) and is based on SPC GeoJSON data instead of the older shapefile-based workflow, improving robustness.

- Added support for the new March 2026 SPC Conditional Intensity Groups on Day 1 through Day 3 outlooks.
- CIG1, CIG2, and CIG3 areas are now handled as separate intensity tiers and can display together when present, matching the SPC graphic model more closely.
- Added dedicated style channels for CIG1, CIG2, and CIG3.
- Enlarged and modernized the on-map convective outlook contour labels for better readability on modern high-DPI displays.
- Expanded the convective outlook label sheet to include 75% and 90% probability labels, plus CIG1, CIG2, and CIG3 labels.
- Updated Scene Builder support so convective outlook selections are preserved and applied, rather than only supporting a simple on/off state.

2. Dual-Source Severe Watch Ingestion + new optimized data sourced backed by mission-critical next-gen WSV3 Tactical server infrastructure

V7.10 substantially updates the private severe watch data path used by WSV3 Professional.

New NWWS-Based Watch Source

-Created a new NWWS-based, instant-updating private data source for severe thunderstorm and tornado watch outline history. This source runs on next-generation WSV3 Tactical Mesoanalyst mission-critical server infrastructure: a bare-metal Pascal daemon running on an optimized ARM64 Linux server.

WSV3 Professional V7.10 still uses the first-gen 2015 polling-based client architecture, so it cannot match the 100% live server-push model used by next-gen WSV3 Tactical Mesoanalyst. However, this new private source gives the legacy V7 client much faster watch availability within the limits of that polling model.

Fixed Legacy TGFTP Watch Backfill

Fixed the legacy private TGFTP-based watch data source used as a backfill path. The legacy source now includes the additional watch information-box data that existed in the older watch source retired for V7.10 because of recently reported update delays.

This means either the new NWWS-based source or the repaired TGFTP backfill source can provide the data needed for complete watch display.

Client-Side Dual-Source Merge

-V7.10 debuts client-side dual-source severe watch ingest. The client now downloads both private watch feeds, merges them locally, deduplicates overlapping products through the existing watch parser, and builds the displayed watch layer from the synthesized result.

This provides the speed and fast refresh behavior of the NWWS/Tactical-based source while preserving TGFTP backfill as a robust backup path during NWWS outage events.

Faster Watch Refresh Polling

The V7.10 client watch refresh interval was reduced from 30 seconds to 20 seconds.

As mentioned, WSV3 Professional V7 remains a first-generation 2015 application with a polling-based product architecture, so it cannot match the fully live server-push model used by next-generation WSV3 Tactical. However, the new V7.10 watch path substantially reduces practical watch latency within the limits of the legacy client architecture.

3. City Label "fixed" mode + collision detection fixes

-Fixed issue with population 0 "fixed" labels
-Corrected fixed city label placement behavior with fixed labels, enabling collision detection between fixed city labels and other label types.

4. WPC QPF Styling Fix

-Fixed a WPC QPF shapefile styling issue where QPF contours could render with the wrong style because of upstream DBF field changes.
-Improved shapefile parsing resilience when upstream field ordering changes.

5. Drought Monitor Cache Invalidation Fix

-Fixed a Drought Monitor shapefile cache invalidation issue that could cause WSV3 to keep displaying stale extracted shapefile data even after a newer ZIP file was downloaded.
