Best Aviation Weather Website?

Here are a few I like to use.

Type in the 3-character airport identifier or city, state and get the
latest forecast. At the top of the forecast page are links to current
regional and local radar maps. The radar maps also have looping
capability, which is great for determining movement of precipitation
areas. You may have to be a member to access the looping capability,
but it's only $5 per year and gets rid of all ads.

Provides links to numerical model forecasts. "eta model forecast"
shows 12, 24, 36, and 48-hour large-scale forecast of pressure,
temperature, and precipitation. The eta model is the most commonly
used model on which short-term forecasts are based in the US. "RUC
model" is the same model, but displays output in 3-hourly instead of
12-hourly time increments. "MRF model" gives longer term predictions.

Click on the state of interest and read the latest forecast discussion
from forecast offices serving various regions in that state. Lots of
technical jargon in there, but it can still be very useful. I find it
particularly helpful to assess "how sure" the forecasters are of their
predictions. Often they'll be less certain of a forecast if the
numerical models (available at http://weather.unisys.com mentioned
above) aren't in close agreement.

A potpourri of satellite, radar, and forecast products. Some
aviation-specific. Easy to use.

www.nws.noaa.gov

Good starting point to download lots of weather maps and forecasts,
including a link for aviation-specific info.
