There are a lot of great weather and climate based resources out there. This page has links to a few, some are weather forecast and historical data, others are GIS resources, and some are just cool ways of representing weather patterns.

There are several climate change related resources on this page as well.

Automated Statistical Downscaling (ASD)

https://grupos.unican.es/ai/meteo/ensembles/index.html

This portal provides user-friendly web access to statistical downscaling techniques and simulations (global and regional model outputs) produced in ENSEMBLES
