MESOPULSE FROM PLACEFILENATION
MesoPulse.
The outlook evolves.
Living weather intelligence that evolves with the atmosphere.
MesoPulse combines broader forecast guidance with current mesoscale analysis, observations, automated analysis, and machine-learning techniques to continuously evaluate whether severe-weather and flood signals are strengthening, weakening, shifting, expanding, or disappearing.
Backed by more than 70 combined years of operational forecasting and meteorological experience, MesoPulse currently provides evolving guidance for Severe Impact, tornado, damaging wind, hail, and flooding.
The LIVE map combines evolving hazard intelligence with optional operational context layers, including NWS alerts and satellite imagery; additional situational-awareness enhancements are in development.

Map first
The live interactive map is the centerpiece — not a dashboard full of unrelated widgets.
Change matters
Current risk matters. How it moved, strengthened, weakened, expanded or shifted matters too.

WHY PLACEFILENATION
Weather data should be easier to use.
PlacefileNation turns public weather data into practical overlays, tools, and intelligence products for people who already know what they want to do with the data.
The goal is straightforward: stable access, fast workflows, clear presentation, and products that are useful during real weather operations.
Stable endpoints
URLs are treated as operational links, not disposable web-page decorations.
Fast access
Search, quick packs, and copy actions cut friction when time matters.
Clear boundaries
Products are supplemental and do not replace official warnings, forecasts, or emergency information.
Build forward
MesoPulse expands the platform without abandoning the placefile users who built the community.
TRUST & TRANSPARENCY
Supplemental weather intelligence.
PlacefileNation provides weather-data placefiles, overlays, mapping tools, and experimental intelligence products. PlacefileNation is not affiliated with the National Weather Service.
Official forecasts, watches, warnings, advisories, and emergency information should always come from the National Weather Service, emergency management, and authorized public-safety sources. Data can fail, delay, or become stale; use all PlacefileNation and MesoPulse products as supplemental situational-awareness tools.
