This likely will reduce/preclude any significant threat later except for areas that see more sun and do not get stabilized early. 

Looks like elevated convection at best.

Nothing severe here with that line, but some booming thunder with lightning and pouring rain.  Winds gusting to 30.

Yup. We at least need the rain. Would be surprised if we actually get into the mid 90s like previously forecast.

       There is some hint of destabilization later today in guidance, and it wouldn't take much with these wind fields, so I don't think we're totally dead.  That said, the models have a lousy handle on the ongoing convection, so the idea that we may be too stable is valid.

Sun is coming out quickly here

This happens *every* time new technology becomes available.  It is sold as the best thing since sliced bread w/ lofty claims.

I recall in the 80s it was said "in 10-15 year advancement in computer modelling will make human forecasting obsolete!'  Right, how did that work out?

In fairness, computer modelling advancement has removed a lot of manual work a human used to do, but this is a *good* thing actually.  Why?, b/c the shear volume of wx data now is enormous and keeps increasing. We need faster computers and AI to help sort and manage it all (do the grunt heavy lifting) so the human forecast can provide the insight/wisdom/understanding -- which AI does not have -- to give concise and clear messages to all.  That's one reason why IDSS is so big in the NWS.  Forecasts have become very good, but the real challenge is *communicating* it all effectively in this information overload and social media world. 

So I would not worry about AI "taking over," so to speak, anytime soon.
 

AI will not remove the forecasters. I can't even get a Comcast AI bot to schedule a service appointment, there's no way an AI person will replace a forecaster at a WFO when I need help.

Weenie comment - but I know we've had some events where early showers/precip gave us some REALLY soupy air and if clearing happens it could intensify fuel for later. 

June 13, 2013 comes to mind. Granted that was a Day 2 MOD, but the morning convection blew through and dropped a surface boundary that fire up the Leesburg to Rockville to College Park tornado.
