One shift, start to finish

WxLens follows the work you already do, from the first look at guidance to the morning after.

  1. Start with what changed

    Every model's newest run for your airport sits in one sheet, shaded against NBM. Runs still arriving say so, and stale data is labelled as stale.

    NBM tonight's low
    −3°

    ECMWF 12Z
    collecting 31/48
  2. Make the call in seconds

    Type or nudge a high and low for each period. NBM's value is frozen the moment you save, so the comparison later is fair.

  3. Give the producer something clean

    Copy a brief or a spreadsheet-ready table. It carries run times, data age and source credits, so nothing old passes for new.

  4. Leave the next shift a note

    Handoff notes sit beside the sheet for your whole station team, with who wrote them and when. The morning crew starts where you left off.

    “Leaning under NBM tonight. Clear skies and light winds by midnight, and the airport decouples early. Watch the GFS warm bias.”

    See how the call verified

    When the period ends, observations from the airport settle it. Your scorecard compares your forecasts with NBM's on the same nights, and only counts calls made before the period began.

Verification you can defend

Beating NBM is the comparison that matters. WxLens keeps the record honest enough that a chief meteorologist can stand behind it.

NBM is frozen when you save
Every forecast is compared with the NBM run you could actually see at the time, never a later one.
Only real forecasts count
Updates made after a period has started are kept, and scored separately from the forecast that came before.
Old data never looks new
Each run shows its age, partial runs say they are partial, and copied output carries the run dates.
Model upgrades stay apart
Every run is tagged with its model version. Results from different versions are never pooled.

Works next to the tools you already have

Keep your graphics system and your map sites. WxLens is the point forecast and the record behind it, with one-click links out to Pivotal Weather, College of DuPage, SPC and your NWS office.

Guidance in the sheet today

HRRR, RRFS, NAM, GFS, ECMWF IFS and NBM, with the AI models AIGFS and AIFS available alongside. Ten-day highs and lows, airport observations, daily normals and records.
