This page has links to various weather sources. Since my weather needs span everything from Pacific typhoons, Australian fog, and midwestern dewpoint spreads, I will try and organize this page as it goes along.
US Domestic Weather
GFS 10-day predictive model – Good for checking the forecast more than 4 days out. Click “model guidance”, then GFS above, and NAMER below. I use the 850mb temp mslp precip model, which is good for about a week in the future.AWC Standard Briefing – Good for a general briefing, I start here.
University of Wisconsin satellite page – Take a look at the Madison satellite, it covers Chicago and is 1km resolution.
CWSU map of Chicago Center – Good graphical view of METAR/TAF info.
ATC Advisories – Select the center and it will show any advisories.
NOTAM database – Enter ICAO ID and get all NOTAMs for the facility.
National Hurricane Center – The source for tropical weather.
GFS-LAMP Real-time Products – One of my favorites, shows realtime model forecasting data for thunderstorms, and airport forecasts. Use to see probabilistic forecast data, most accurate 12-16 hours out.
