Wednesday Weather Briefing: Weather battleground setting up for second half of the week...

Submitted by: Daniel Crawley


Good Wednesday morning to everyone, the weather pattern is becoming active once again across the Carolinas. After dealing with several warm and sunny days post-Florence, the clouds have returned in a big way so far this week and most locations has received a bit of rainfall. That will continue for today and if anything will begin to pick up here for the second half of the work week…

 

 

Water vapor imagery shows a nice trough that is moving through the northern tier of the country. Meanwhile high pressure is slowly giving way across the Southeast US, it is all setting up a battle ground between each feature with southwest flow providing a good moisture tap in the mid and upper levels. Meanwhile southerly winds at the surface will saturate the lower levels.

This battle ground appears to be locking in for today and lasting through the end of the work week and into the upcoming weekend. A couple days ago it appeared that the region may get a good push of cooler and less humid into the region but that has changed at bit. The Southeast ridge is going to remain stubborn and will not give up its ground without a fight. As you can see on the upper level charts, the ridge continues to take a southwest to northeast configuration, much like a kidney bean shape. This is a classic fall look at the upper levels across the Eastern US. This in configuration with slow moving surface boundary will provide a trigger for showers and thunderstorms in several waves. The heaviest action looks to begin later today and last through Thursday and into Friday…possibly impacting High School Football games on Friday night.

It’s not until Saturday that our ridge will finally begin to flatten just enough to where some drier air may filter into the state of North Carolina. As you can see on the Saturday upper level charts the southwest flow veers more to a west and west-northwest flow…

Coming back to the short term, the short range models are picking up on increased rain chances starting this afternoon and lasting through Thursday. This by no means will be an all-day rainfall, but instead periods of rain shower activity. A few rumbles of thunder also possible with this boundary.

The periods of rainfall again will persist beyond Thursday morning, it may not be until Saturday before parts of the coverage area may dry out.

 

This should give most everyone a solid chances at getting rainfall totals in the 1 – 1.5 inch range through Saturday…

 

Have a great Wednesday!
