Earliest Alert 5.25.18

Welcome to the holiday weekend!
As we plan out the outdoor events and memorials...the headlines for the weekend remain the same.

Humid, hot and the risk for very heavy downpours.

The good news is that we are getting better data this morning that is helping us to group the rain chances during the weekend setup.  One trend that was becoming apparently was the increase in thunderstorm coverage Saturday.  Still not a washout setup, but there radar will have moments where it is will be lit up with many clusters of heavy rain and intense lightning.  Mixed in with that will be hazy sunshine.  Just make sure you are aware of this potential.

Otherwise, this afternoon's rain chance still looks isolated and to the south east.  
There is a fading boundary to our west that spark thunderstorms near St. Louis and work them east into WAVE Country overnight tonight.  They look to fade as that move in, so the rain chance is there west of I-65, but low.

It is that faded boundary that will help promote the greater t-storm coverage for Saturday.

On Sunday, we have the humidity, but not the trigger.  So other than spotty thunderstorms, most of you will remain hazy and humid.

Same story really for Memorial Day.  In fact, humidity levels may even drop just a smidgin to allow for a hotter day into the lower 90s.  Rain chance will still exist, but looks to remain low for now.

Why the changes toward the end of the period?
The tropical wave in the Gulf.  It likely will become a tropical storm (Alberto) over the weekend. With it trending stronger to storm status, that should keep the deeper moisture closer to its center with a drier setup on its N/NW side.  Which will get awful closer to us to help us out.

The down side in that trend is that it (Alberto) is showing signs of getting pulled northward into WAVE Country next week.  That would really ramp up the rain chance and even lead to flooding concerns.  Still some questions on that setup right now.

Attached is the video update for today!  Enjoy the weekend and be safe!
