Description

WarnWeather is a weather watchface for Pebble, inspired by ForecasWatch2. It packs a
whole day of temperature, precipitation, and wind into a single graph, and keeps a
3-week calendar and a live rain radar one wrist-flick away.

FORECAST GRAPH VS. RAIN RADAR
The forecast graph is the hourly prediction — looking up to 24 hours ahead, it shows the
chance of rain each hour. It's a model forecast, good for "will it rain this afternoon?"
The rain radar is short-term and based on actual radar measurements moving toward you: it
turns the next 2 hours into a bar graph where each bar is one 5-minute frame and its height
is the rain amount, so you see exactly when (and how much) rain reaches your exact spot.
Good for "is it about to rain on me right now?"
