Each model's day runs midnight to midnight local time; models that reach fewer days are left blank. Rain: daily total. Wind: the day's highest average wind and, in small type, the strongest gust. Highlighted: values that stand out from the rest. The chance of rain comes from many runs of the same model with slightly different starting data.
