Friday's weather across the Lower 48 is forecast to be so quiet that weather maps are showing up virtually blank... During more active weather, this NWS webpage can resemble modern art, sprayed with a Crayola box full of colors representing multiple warnings, watches and advisories for severe thunderstorms, flooding, snow, ice and wind. While these quiet days aren't tracked as far as we know, anecdotally, we don't believe they happen more than a couple of times a year.
