Chance of rain from the ensemble models

Model	Today	Fri 30	Sat 31	Sun 1	Mon 2	Tue 3	Wed 4
ECMWF (51 scenarios)	10%	0%	0%	8%	22%	4%	2%
GFS (GEFS, 31 scenarios)	3%	0%	0%	7%	45%	22%	16%

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.

Weeks: ECMWF 46-day (average of its scenarios), against the normal of the last 20 years for those dates. Months: ECMWF SEAS5. Rain: total against normal. The further ahead, the closer it gets to normal and the less detail it can give. The long-range sea temperature isn't usable at this spot (the model's grid cell falls on land).
