Depending on how the forecast goes, if it isn't as expected remember what day it is. :-P

Slight Risk for tomorrow, main storm mode will be elevated hail producers. Another round of some good rain for Oklahoma nonetheless.

Slight risk tomorrow is generally east of a line from just west of I-35 up through Canadian County and then northeast to Osage county.

The outlooks typically run 7AM to 7AM, not Midnight to Midnight. Yeah, everything else down the road right now looks really isolated or pretty tame. But things are able to change on a dime this time of year.

I don't think today is going to change on a dime or a nickle or a penny or a quarter for that matter, lol.
