I have not found a really good source for current Jet Stream analysis
and Forecast Charts.

This is the best one I've seen so far:

Anyone got a better source? In the past I've seen similar charts from
NOAA or NWS[?] That had a white background and was quite a bit
clearer.

looking to upgrade my wx page:
