Time runs across. Height is maximum sustained wind, read from each status's METAR. The red ring marks the current position, and the cone ahead of it assumes conditions persist.
Meteogram /the last two days and the week ahead/
The chance of an update in each six hours comes from this project's last four weeks: its usual days and hours. The sky, the wind, and the pressure follow from that, its own storm fading as its usual updates bring new weather. The shaded part is the last two days, as they happened. It is persistence and climatology, the two simplest forecasts there are, and no promise of what will be logged.

Recurring system, first observed years ago and now redeveloping over orbital waters. The Cartesian derivation is expected to be long.
