The last 13 hours along this shore
Every meter on this chain, half an hour to a column. A diagonal band of bright cells is wind moving along the coast, and your station is marked. 1 of 5 meters have hit 12 kt in that window.
5 meters on the Lake Superior - South Shore chain. Each column takes the nearest reading within 25 minutes of it; hatching means that meter sent nothing, which is a different fact from a calm one. Nothing is modelled and nothing is filled in between meters. 2 meters on this coast are permanently offline and absent from the picture entirely — we would rather show the hole than paint over it.
