SPC already has Slight Risk areas posted for OK, KS and surrounding areas for Tuesday and Wednesday.

Not much of a threat, but OK doesn't really need anything right now.

Definitely nothing like last week, more typical summer like showers with scattered to isolated severe weather. Oklahoma doesn't need the flooding but lets remember this part of the country has been in severe drought for years so this somewhat needed. All droughts end in flood unfortunately, and it looks like they will add on more rain.

What has amazed me is central OK has been in the moderate and slight risk areas like non-stop since May 14...its becoming unusual now. OK truly has the worst severe weather on earth (thunderstorms).

Yeah, but that week kind of fizzled out. More just typical spring weather.

Funny thing is, 'Slight Risk' seems to mean different things in different areas. It can mean some pretty nasty stuff for the Ohio valley, but that's an area that doesn't see the scale of severe that the plains do.
