Good Wednesday everyone and thanks for making the blog one of your weather stops. A major rainfall event is likely across the entire state over the next few days and this will lead to an increasing threat for flash flooding and even river flooding.

We have been setting the table with this event for a while now and the parameters appear to be in place for a lot of water to fall from the sky in a short period of time. Low pressure will be developing later today in the plains states and will roll northeastward toward the lower Ohio Valley later Thursday into early Friday. This happens as warm, moist air surges northward into the region and interacts with a warm front draped across the area. This will be the initial focusing mechanism for a wave of rain and thunderstorms to form late tonight into early Thursday.

Additional waves of rain and storms will crank up along this boundary into Thursday night. It is by this time we get an additional surge in the action from the low itself. Here is a visual on this setup…
 


This will lead to widespread heavy rains from Arkansas and Tennessee northward throughout the entire state. Here is a look at what i’m currently expecting…



The impressive part about the rain is most of it will fall in less than a 24 hour period. I would anticipate flash flood watches coming soon from the local NWS offices that service our region.

On a brighter note… the greatest threat for severe weather may stay just to our south and southwest. It is still close enough to keep an eye on, however.

After a lull in the action Saturday… watch out. Another, more powerful, storm will move into this region later Sunday into Monday with another round of heavy rainfall and a possible higher threat for severe thunderstorms. Here is the GFS…

Sunday Afternoon


Sunday Night


Between the late week storm and the one coming late weekend into early next week… that is a whole lot of rain that can fall across our entire region. That may lead to local flash flooding and even river flooding and anyone living in a flood prone area should stay alert to the high water potential over the next several days.

As usual… the blog will update you every step of the way so check back for updates. Have a great Wednesday and take care.
