Model agreementHow to read this
The big number is our blend of every model, each corrected by how it has verified here. Where there is no blend yet, it is the middle model's.
Under it, the range is the lowest and highest high the forecast models give for the day. Where they disagree a lot, the two models at the ends are named.
Rain is the middle model's chance of rain and the middle model's total.
Model agreement is how close the models' forecasts for one day sit to each other once each model's usual lean at the place is set aside, judged separately for the high, the low and rain: good, fair or poor against how far apart they usually are that many days out, and for rain against the band of chances where a plan changes.
These are the numbers from the models' last run we stored, at the time above. They are not an official forecast, and this page carries no weather warnings: for those, see the National Weather Service.
