I'm pleased to announce that the website I have been working on is progressing nicely. While there are many sites that provide model forecast graphics (and there is technically nothing new here on the model front), not every site shows them in ways favorable for chase forecasting. To that end, I have taken 4 km NAM CONUS nest data and made a series of forecast plots specific for those looking to make a chase forecast. Those graphics can be found on the bottom half of the page linked above.
You'll notice the top half of the page is for GFS time-lagged ensemble products. While you can view dProg/dt graphics on other sites (like twisterdata), what I've done here is to combine all of those into one product valid at each time. Therefore, each GFS control run is effectively an ensemble member in which different members are given by other GFS control runs initialized at different times. This will give an idea of how stable a given forecast is for the GFS. Due to computational limitations, there have been problems getting the GFS TLE plots to be stable and available at regular intervals. Therefore, this part of the page will continue to undergo significant changes as I search for a series of plots that is computationally feasible. Most likely, these products will focus less on specific severe weather forecasting and more on general synoptic and mesoscale forecasting (still useful for making a chase forecast, however).
I welcome all sorts of comments, critiques, and/or suggestions. Is there a product you'd like to see that isn't there? Is there a product you don't find useful? How are the color schemes? Do the plots with a lot of fields in them clutter the map? Things like that.
ADDED 2/9/2013: see page 2 for update information on GFS TLE products.
