Chasing from home today unless something develops within 50 miles of Fort Smith today and then i might have a go. Looking at the visible satellite there is hardly any clouds at all across much of the slight and all of the moderate risk area. I dont think i have even been out and by 2pm not had any clouds at all at any level. Usually i like to have at least a few cu clouds by this point and this got me thinking about what some of you have seen as far as going from completely clear to storms?? Whats the quickest you have seen storms go from nothing?
